What Actually Slows Aging? The Science vs. Hype | Dr. David Barzilai

Fri, 25 Sep 2026 13:48:57 -0400

In this episode of New Frontiers, Dr. Kara Fitzgerald sits down with longevity physician Dr. David Barzilai to separate promising science from hype and explore where the field of longevity medicine is headed.

They discuss the evolution of biological age testing, including DunedinPACE and other aging clocks, and why these tools can provide useful information without telling the whole story. They also explore how AI and emerging technologies could transform personalized medicine, helping clinicians better identify which interventions may actually benefit an individual.

You’ll also hear why the fundamentals still matter, how to think critically about the growing number of supplements and longevity “hacks,” and which emerging interventions deserve attention as the science evolves.

In this episode, you’ll learn: - What biological age and aging clocks can—and can’t—tell us - How to distinguish promising longevity science from hype - Why slowing the rate of aging may matter more than chasing a biological age number - How AI could change personalized longevity medicine - Why individualized diet, exercise, sleep, and other foundational interventions still come first - How clinicians can evaluate emerging longevity therapies without getting ahead of the evidence - Where longevity and geroscience may be headed next

If you’re interested in biological aging, healthspan, precision medicine, or the future of longevity science, this conversation offers a practical look at what we know today—and what may be coming next.

The Estrogen Effect Nobody Talks About | Kiran Krishnan

Tue, 05 May 2026 00:00:00 -0400

Cardiovascular health and longevity are deeply influenced by aging, perimenopause, and systemic changes that extend far beyond cholesterol markers alone.

In this episode of New Frontiers in Functional Medicine, Dr. Kara Fitzgerald sits down with Kiran Krishnan to explore the biology of vascular aging, endothelial dysfunction, and metabolic changes that emerge in midlife and beyond. As estrogen declines during perimenopause, patients often experience shifts in lipid metabolism, weight regulation, and overall metabolic resilience—driving increased cardiovascular risk.

This conversation dives into the critical role of the endothelial glycocalyx, nitric oxide signaling, and the gut microbiome in maintaining vascular integrity and systemic health. Dr. Fitzgerald and Kiran connect the dots between gut health, cardiovascular disease, joint degeneration, and systemic inflammation, offering a systems biology approach that is highly relevant for functional medicine practitioners.

You’ll also hear how targeted interventions—specifically Arterosil, Vascanox, and Cartigenix—can be used synergistically to support endothelial health, nitric oxide production, microbial balance, and joint integrity.

Topics covered include: - Endothelial glycocalyx dysfunction and cardiovascular risk - Nitric oxide signaling and vascular health - Perimenopause, estrogen decline, and metabolic changes - Gut microbiome influence on cardiovascular and joint health - Anabolic vs catabolic balance in aging - Clinical applications for Arterosil, Vascanox, and Cartigenix - Moving beyond LDL: a systems-based approach to heart health

This episode provides a clinically grounded, functional medicine perspective on aging, cardiovascular disease prevention, and whole-body resilience.

The Hidden Immune Signal Accelerating Aging & the Beta-Glucan That Fixes It

Tue, 02 Dec 2025 00:00:00 -0400

Beta-glucans might be one of the most overlooked levers in immune resilience, and that has major implications for longevity. Talking with my long-time friends and colleagues Drs. Bob Rountree and Chris D’Adamo reminded me just how powerful this molecule truly is. The clinical reach here is stunning, from immune aging and cancer support to vaccine response, gut–brain effects, and overall resilience. What struck me most is how beta-glucans help the innate immune system respond more effectively over time, from overtraining and chronic infections to vaccine responsiveness. Clinicians really need this on their radar.

Why Centenarians Are Defying Science: Secrets to Living 100+

Sun, 17 Aug 2025 00:00:00 -0400

It was a pleasure to sit down with Dr. Nir Barzilai for a conversation that turned out to be both lively and thought-provoking. His decades of research on centenarians, biological age, and the hallmarks of aging have shaped how we think about longevity—and what’s possible when we start targeting aging itself, not just individual diseases.

We get into the science behind why some people live 20–30 years longer and healthier, and what it means to measure the biological age of individual organs. But we also hit a few sparks—especially when it comes to nutraceuticals and the role of metformin in prevention. I don’t agree with everything you’ll hear, and I followed up with Dr. Barzilai afterward to unpack some of the more provocative claims. We may just need a second round for this one... stay tuned.

The Science-Backed Bitter Compound That Mimics GLP-1 (No Injections Needed!)

Tue, 05 Aug 2025 00:00:00 -0400

I’ve been watching the science behind Calocurb evolve over the last year, and I have to say—this is one of the most exciting clinical tools I’ve seen emerge in the metabolic space in quite some time. A hops-derived compound that stimulates endogenous GLP-1, CCK, and PYY—without a prescription or injection? That’s a big deal, especially for patients struggling with appetite regulation, weight plateaus, or the aftermath of GLP-1 discontinuation.

In this episode, I sit down with Sarah Kennedy, founder of New Zealand-based Calocurb, to talk about the years of government-funded research that led to this discovery, the remarkable clinical outcomes they’ve seen so far, and how I’ve personally used it in my practice with excellent results. If you’re looking for science-backed, natural strategies to support appetite control, fasting, or GLP-1 transitions—this one’s worth a listen. ~DrKF

10 Year Anniversary: What I Learned After 200+ Conversations with the Best Minds in FxMed

Tue, 22 Jul 2025 00:00:00 -0400

In this very special episode, I have the privilege of turning the tables on Dr. Kara Fitzgerald as we celebrate 10 years of the New Frontiers podcast. I’ve been honored to walk alongside Kara on much of this journey—as a colleague, a collaborator, a mentee, and a friend—and it’s been incredible to witness the evolution of both her work and the field itself.

Together, we reflect on the stories, science, and people who have shaped this podcast—and the remarkable growth of epigenetics, personalized medicine, and functional medicine along the way. From early conversations around methylation and aging to hosting pioneers like Dr. Jeff Bland, Dr. Sidney Baker, and Dr. Charles Serhan, New Frontiers has become a living archive of how this field has moved forward.

As we talked about during the conversation: “Everybody is a piece of this ecosystem, and everybody has their role... It’s really cool to be part of that community.” This episode is a celebration of that collective journey—and a look at where we’re headed next. ~Romilly Hodges MS CNS

Dead Mitochondria Might Be Fueling Cardiovascular Aging — Here’s The Fix

Tue, 08 Jul 2025 00:00:00 -0400

This is a really exciting conversation with Dr. Davide D’Amico from Timeline, where we’re taking a closer look at Urolithin A and heart health. It should come as no surprise that this mitochondrial wonderkin of a nutrient is showing promise here—especially when you consider that 40% of the heart’s weight is mitochondria. That’s an extraordinary factoid, and one that really shifts how we think about aging in the cardiovascular system.

What’s particularly compelling in this new preclinical research is that restoring mitochondrial function may do more than just improve ejection fraction. It may also have ripple effects on other hallmarks of aging—like chronic inflammation, cellular stress signaling, and impaired autophagy. I’m thrilled Timeline is continuing to invest in both preclinical and clinical research on this front—and yes, I’m totally nerding out over what they’re up to. ~DrK

Why Human-Centered AI Is the Future of Medicine & Mental Wellness

Sun, 22 Jun 2025 00:00:00 -0400

This episode is a little different from what we usually cover on New Frontiers, but it’s one I couldn’t wait to bring to you. I’ve been thinking a lot about how we—as clinicians—are supposed to keep up in this era of high-throughput technology. We’re swimming in data: labs, multi-omics, diet logs… and an ever-growing stream from wearables. There’s just so much coming at us, and too often, we’re awash in a sea of information without adequate interpretive power.

That’s why this conversation with Dr. Rana el Kaliouby felt so important. She’s not just an AI scientist—she’s a visionary and a total badass. She’s building technology that doesn’t just process data, but actually helps us become better clinicians and better humans. We get into the ethics, the potential, the parenting implications—and yes, a personal story about a tragedy in my own hometown that made this all hit very close to home. This one’s powerful, and I hope it sparks the same questions and inspiration for you as it did for me. ~DrKF

TRIGGER WARNING

This episode touches on sensitive topics, including gun violence and suicide, in the context of empathy, mental health, and technology. If you or someone you know is struggling, please seek help. We share this with care and hope it offers support and perspective.

What New Research Says About Cartilage Regeneration and Joint Longevity

Mon, 05 May 2025 00:00:00 -0400

What if a human trial of over 1200 patients showed improved mobility and reduced pain in osteoarthritis (OA) patients using a natural combination of boswellia and celery seed extract? What if a second follow-up randomized, placebo-controlled human trial found that within 90 days, this same combination increased OA patients' ability to perform a walk test by over 50%, reduced markers of cartilage degeneration by half and increased markers of cartilage regeneration by half. This is what the research team at Calroy Health Sciences have discovered, putting a tremendous amount of work and financing into studying the effects of the uniquely-developed Cartigenix-HP. Not only that, increased joint space at the end of the trial was clearly visible via radiography, and 90% of the intervention group did not need any "rescue" pharmaceutical medication at the end of the 90 day period (compared with only 20% of the placebo group) and this effect was sustained beyond the end of the trial. I have to say, I am impressed and excited about the potential for this new product to help my patients and I am thinking about other applications like OA prevention and osteoporosis! Listen in to find out more. ~ DrKF

The Truth About Chronic Illness: How to Reset Your Nervous System & Slow Aging

Sun, 20 Apr 2025 00:00:00 -0400

We’ve all had patients struggling with chronic conditions like long COVID, fibromyalgia, Lyme disease, and chronic fatigue. Despite all the tools in our functional medicine toolkit, there’s still something missing. How can we truly help them? I’m excited to have Ashok Gupta back on the New Frontiers podcast to offer a new take on healing from chronic illness. He explains that many chronic diseases stem from a malfunction in the brain's threat detection system, where the body overreacts to perceived threats, triggering immune, nervous system, or mood responses, creating a vicious cycle. Ashok shares how retraining the brain and calming the nervous system can reset the body’s response to chronic stress and presents the growing body of research supporting the Gupta Program, including new subjective measurements like CRP showing its impact. What excites me most is the potential for this approach to help some of my toughest-to-treat patients. With more studies emerging, I’m increasingly hopeful this could be a game-changer. It’s a conversation you won’t want to miss! ~DrKF

Hidden Mitochondria Problems Are Accelerating Your Age & Draining Your Health

Tue, 08 Apr 2025 00:00:00 -0400

What if the key to reversing chronic disease, slowing cognitive decline, and boosting energy lies in the tiny powerhouses inside your cells—and we’ve finally found a way to protect them?

We know mitochondria power our cells, but did you know they also create oxidative stress as they generate energy? Protecting mitochondrial health is critical—but most antioxidants can't reach inside the mitochondria where protection is needed most—until now. MitoQ, a scientifically advanced, mitochondria-targeted antioxidant developed by visionary researchers in New Zealand penetrates mitochondria up to 90%, offering protection where it's needed most.

In this episode with Dr. Siobhan Mitchell, we dive into how MitoQ is transforming the way we tackle chronic disease, inflammation, and cognitive decline. From improving heart health to supporting brain function, MitoQ is changing the game. It’s something I’m using personally and recommending to most of my patients. Listen in to discover how this powerful tool can help you support your patients at the cellular level—before symptoms even appear. ~DrKF

A Fresh Take on Exposomics: Resiliency Factors That Offset Environmental Risks

Thu, 20 Feb 2025 00:00:00 -0400
It’s very difficult (often impossible) to completely avoid many of the environmental toxins that can cause harm - like air pollution and forever chemicals that contaminate our water and food supply. But Drs. Bob and Rosalind Wright at Mount Sinai have a hopeful solution to this dilemma. They are pioneering the study of “resiliency factors,” not just “risk factors,” that can offset the risks of harmful exposures. It’s a fresh and welcome take on exposomics that I am very excited to share with you. For instance - did you know that omega-3 intake during pregnancy can protect against the development of asthma in the child, even if the child is exposed to known risk factors for asthma? Or that positive relationships (ones that create a sensitive, positive, caregiving environment) have been shown to potentially mitigate the effects of environmental toxins? As a practitioner, I am always looking to empower patients with real solutions to the health challenges we inevitably face and I hope you enjoy this conversation as much as I did. ~DrKF

The Podcast After the Podcast: More on Age Reversal with Dr. Greg Fahy

Fri, 06 Dec 2024 00:00:00 -0400
After my conversation with Dr. Greg Fahy in August, I realized that I had additional questions that we didn't have time to address the first time around. Importantly, since here I am studying the effects of dietary and lifestyle interventions on aging, I wanted to know his thoughts on the dietary components of the TRIMM study and beyond. Dr. Fahy shares his thoughts on my question and some others on side effects on different medication and supplement interventions, the mechanism by which he thinks the restoration of hair color occurred in some of his study participants, and how to think about (and feel motivated about!) incorporating safe exercise. This brief bonus podcast episode is just right for squeezing into your holiday schedule. Enjoy! ~DrKF

Innovative Approaches to Restoring Brain Function After Concussion and TBI

Mon, 25 Nov 2024 00:00:00 -0400
The brain’s ability to recover after trauma is astonishing—and often overlooked in conventional care. In this episode of New Frontiers in Functional Medicine, I sit down with Dr. David Musnick, a long-time friend and brilliant clinician, to explore how we can unlock the brain’s full potential for healing. Dr. Musnick challenges the standard of care for traumatic brain injuries and post-concussion syndrome, introducing a functional medicine approach that integrates advanced tools like Frequency-Specific Microcurrent, targeted nutritional strategies, and personalized interventions.
His insights into the stages of recovery, the importance of addressing neuroinflammation, and the role of the gut-brain connection were a true "aha" for me. We also dive into groundbreaking methods for reversing secondary brain damage, a concept that could change everything for patients and practitioners alike. This conversation is packed with actionable takeaways and hope for those navigating brain injuries, cognitive impairment, or persistent post-concussion symptoms. You don’t want to miss it.~DrKF

An HRT Revolution is Underway. Ready to Individualize Recommendations for Hormone Health?

Tue, 19 Nov 2024 00:00:00 -0400
For anyone who has been paying attention, you may already know that the takeaways related to hormone replacement therapy (HRT) from the original Women’s Health Initiative (WHI) study have been completely overhauled. It’s about time! As a result, it’s not an understatement to say that we are in the midst of a total transformation in hormone replacement therapy (HRT) and it’s essential that as providers we (1) get up to speed on the nuances of the new interpretations and (2) learn how to personalize the guidance we give. Dr. Allison Smith, from Precision Analytical, is really a bright, guiding light in this new era of hormone care. She joins me in this episode of New Frontiers to start to unpack some of those important considerations and share resources for where practitioners can learn more. She explains why more detailed hormone metabolite testing can provide answers to hormonal symptoms when standard serum measures of testosterone and estrogen are “normal.” She also shines a light on the need for understanding how our patients are metabolizing hormones, especially if they are on HRT as well as to optimize their long-term cardiovascular, bone, skin, and brain health. This is indispensable listening and I’m sure you’ll enjoy this conversation as much as I did. - DrKF

Are You a Fast Metabolizer of Omega Fatty Acids? Lessons from a Legend

Tue, 29 Oct 2024 14:47:16 -0400
It’s not overstating it to say that I have cited Dr. Artemis Simopoulos’ work in virtually every lecture I have ever given that included the topic of omega-3 fatty acids. She is an incredible human being, indomitable NIH researcher, and absolute legend in her field. In our conversation on New Frontiers, Dr. Simopoulos reviews those essential truths about the evolution of our dietary intake of omega-3 vs. omega-6 fatty acids, the increase in ultra-processed food consumption, and how these play into our health landscape today. She also pulls on some particularly interesting threads around genetic variability in our ability to metabolize fatty acids and the implications of this for inflammatory conditions (of course, almost all chronic diseases have an inflammatory component). This is especially relevant for “rapid metabolizer” populations that tend to over-produce prostaglandins and leukotrienes, compared to resolvins, when exposed to a standard American diet. I know her insights will inform how you personalize your recommendations. - DrKF Check out the show notes at https://www.drkarafitzgerald.com/fxmed-podcast/ for the full list of links and resources.

A 360-Degree View of the Microbiome: Practical Strategies for Clinicians

Thu, 10 Oct 2024 19:35:27 -0400
The centrality of gut health in total body health and aging means it’s a key topic for us to keep revisiting and updating our knowledge on. For instance, how confident do you feel about interpreting analytical indices such as phyla distribution, dysbiosis index, diversity score, as well as the myriad bacterial populations that can be resident in the GI tract? Join me and Dr. Julia Malkowski as we dive into advanced stool testing and how the insights gleaned from the GI360 test can tell us a lot about our patients’ health and lifestyle (ever wondered how the carnivore diet, long-term use of GLP-1 agonists, or chronic stress impact the gut?). We also explore keystone bacterial species and their impact on systemic health, what is better than fiber for increasing microbiome diversity, different testing methods including the impressive MALDI-TOF Mass Spectrometry Technology and a ton of clinical pearls on tackling those report findings in clinical practice. There is something for everyone in this excellent conversation with Dr. Julia Malkowski, from the newly-minted to the seasoned functional medicine practitioner, and health-savvy consumers too.

Promise and Controversies: State of the State of Longevity Science with Matt Kaeberlein, PhD

Thu, 26 Sep 2024 18:56:14 -0400
It's important to me to include a variety of voices in the sphere of aging and longevity, and Matt Kaeberlein PhD is certainly one that I appreciate for his tempered and rational arguments. I value his insights and his work with other scientists who are tussling with the challenging questions and research interpretations in this field. We are at this extraordinary inflexion point where scientists are debating the very definition of aging itself, which has important implications for how we then measure and study it. Dr. Kaeberlein shares his thoughts on this as well as the latest on longevity interventions such as rapamycin, metformin, intermittent fasting, and caloric restriction. Find out why he thinks we'll always hit a wall with moving the needle on lifespan, and why healthspan is such an important target. I think you will find this conversation illuminating and useful. An additional note for any of my listeners/readers who have been tracking the various discussions around the utility of epigenetic clocks and other measures of aging: I personally very much believe in epigenetics, even as the field continues to evolve. The foundation of this traces back to my beginnings in this field, working under my mentor Richard Lord PhD, who taught me that as scientists and clinicians we have no choice but to embrace uncertainty. No laboratory tests are as precise as many of us would like to think they are - microbiome, organic acid, nutrient testing, those foundational tools of functional medicine that we are very comfortable using, included. This applies to standard labs too - I recently received a notification from one of the two biggest labs in the US stating that, due to a change in the testing instrument used, values for red cell indices (the oldest tests on the planet!) would be altered compared to prior results. As clinicians we have to grapple with uncomfortable uncertainty in medicine every single day - from that reality we still have to move forward and make the best clinical decisions we can. Epigenetic age testing is simply another tool in the mix that can add value to understanding a patient's picture, and we can use it even as we interpret it with a similar acknowledgement of uncertainty. If you would like to add your thoughts to this discussion, please share below. - DrKF

You Are Only As Young As Your Immune System with Dr. Greg Fahy

Thu, 22 Aug 2024 11:29:52 -0400
Your thymus isn't talked about much, but this small organ in your upper chest is a key component of your immune system that is solely responsible for the essential "education" of the immune cells that protect your body from invaders. Through this action it also affects levels of inflammation (an immune-mediated process). It's also interesting to note that most of us end up dying of an immune-related dysfunction - even cardiovascular disease, as Dr. Greg Fahy points out in this New Frontiers podcast, is often caused by atherosclerosis driven by underlying chronic inflammation.
I was thrilled to finally sit down with Dr. Fahy, whose groundbreaking work in aging has reshaped our understanding of what’s possible. His 2019 TRIIM study, showing clear epigenetic age reversal through thymus regeneration, was an absolute game-changer. The thinking prior to that was that epigenetic age reversal was not possible! It was exciting to read his publication as we were in the midst of our own original clinical trial. I'm sure you'll enjoy his recounting of that adventure and just how he's rejuvenating thymic function, the rationale for targeting immune rejuvenation, and the trial extensions he's currently working on now. ~ DrKF

Resolving Chronic Inflammation using SPMs: A Two-Phase Approach with Ashley Koff RD

Tue, 25 Jun 2024 18:04:35 -0400
Practitioners, if specialized pro-resolving lipid mediators (SPMs) aren't already on your radar, you'll be a convert by the end of this New Frontiers episode.

In functional medicine, we excel at addressing inflammation through nutrition and lifestyle. However, brilliant researchers like Dr. Charles Serhan from Harvard have shown us that resolving inflammation requires a two-phase approach. We need to shift gears, rally the cleanup crew, start the repair process, and turn down the volume on the immune system. This transition from inflammation to resolution is exactly what our guest, Ashley Koff, RD, will discuss.

We'll explore why SPMs, discovered by Dr. Serhan, are crucial for healthy inflammation resolution and how Metagenics has developed a product using the patented Serhan method that has numerous clinical applications, from managing inflammation and pain to addressing neurodegenerative conditions, autoimmunity, and even infertility. We'll also delve into factors that influence our ability to convert omega-3 and -6 fatty acids into these superstar molecules, such as diet, genetics, inflammatory bias, and poor vagal tone. This conversation is packed with clinical pearls for your practice and personal use. Enjoy. ~DrKF

Towards Predicting Autism in Utero with Dr. Janine LaSalle

Wed, 12 Jun 2024 16:10:55 -0400
What if we could actually identify and even correct significant autism risk factors in utero, before a baby is born? This is the promise of the game-changing research of Dr. Janine LaSalle, epigeneticist extraordinaire from UC Davis. With autism rates continuing to increase at alarming rates (the latest data from the CDC, released in 2023, is 1 in 36 children in the US, an increase from the prior 1 in 44), new ways to prevent and treat this condition are of utmost importance. Dr. LaSalle is on a mission to change that, by investigating something you probably haven't heard much about yet - the placental methylome. Methylation signatures in the maternal placenta are yielding information both for predicting autism in children and for intervention targets to prevent the development of the disease. It's just incredibly exciting.
In our conversation, you'll also learn how placental methylation behaves differently to DNA methylation in other tissues, and how the placental methylome may also help us better understand cancer as well as mechanisms that restore more youthful epigenetic patterns. Hold onto your hats folks - yes this is deep science, but it's also actionable even now. You'll hear how methylation support specifically in the early pregnancy window is key and how it's also protective against insults from environmental toxicants. You’re in for a treat with this fascinating conversation that has far-reaching implications for you and your patients. ~DrKF

Challenging Food Reactions? Addressing the Gut Microbiome and More with Dr. Thomas Fabian

Tue, 21 May 2024 21:12:57 -0400
Addressing adverse food reactions goes way beyond simply cutting out the culprits, so I’m thrilled to have Dr. Tom Fabian join us again on New Frontiers to highlight the interventions that will move the needle for our patients. We explore the mechanisms through which specific strains can either exacerbate or alleviate both immune-mediated and non-immune-mediated food reactions, and discuss the fascinating connection between circadian rhythms of mast cells and intestinal permeability, feeding times and increased susceptibility to food reactivity. We look at why some patients may be more sensitive to symptoms and how histamine-producing microbes may lead to visceral hypersensitivity. But we also talk strategy, with one pearl after another, such as the potential of Lactobacillus reuteri in attenuating immune-mediated food reactions, the role of butyrate and indole in stabilizing mast cells, and using specific polyphenols to calm the immune system and promote a health microbiome. For any practitioner or health-savvy individual grappling with these issues, this is an episode you won’t want to miss. ~DrKF Head over to https://www.drkarafitzgerald.com/fxmed-podcast/ for the transcript, a COMPLETE LIST OF SHOW NOTES and all the FxMed resources.

Mitigating Muscle Loss from GLP-1 Agonists, with Dr. Anurag Singh

Thu, 25 Apr 2024 20:19:07 -0400

Even as we prioritize natural interventions in functional medicine, GLP-1 agonist drugs such as Wegovy and Ozempic offer sometimes life-changing support for those who have long struggled with resistant overweight/obesity and high blood sugar. However, there are side effects, including the risk of substantial muscle loss and sagging, aged skin ("Ozempic face" as it's indelicately known). It's a concern that hits home for me, considering the pivotal role we know that muscle plays in overall health and longevity.

In this New Frontiers podcast episode I welcome back Dr. Anurag Singh to unravel the complexities of these issues. We explore the interplay between metabolic health and muscle preservation, touching on everything from the mechanisms of GLP-1 agonists and their long-term effects on aging and sarcopenia, to the promising potential of dietary and lifestyle interventions to counteract negative effects. We consider the potential for one of my all-time fave postbiotic epinutrients - Urolithin A - to assist by supporting mitochondrial health and preserving/enhancing muscle quality. This timely conversation is one you won't want to miss. Tune in and please leave us a review wherever you listen to New Frontiers. – DrKF

Tackling Alzheimer's Disease Head On - the Inspiring Work of Dr. Heather Sandison

Tue, 09 Apr 2024 20:25:31 -0400
Dr. Sandison confesses that when she first heard Dr. Dale Bredesen talk about his work reversing cognitive decline and Alzheimer's disease she was skeptical. But when she started to apply the Bredesen principles in her clinical work and saw just how meaningful the improvements were to patients' symptoms and quality of life, as she puts it: "...how do I do anything else with my life, but basically tell as many people who will listen that this is possible?" She then went on to found the first two residential care facilities for individuals with cognitive decline that are based on the Bredesen approach. She's published research on her clinical outcomes and is continuing to gather more data for publication. The information and inspiration she shares are relevant to anyone dealing with cognitive decline, caring for someone with cognitive decline, or even those of us who want to preserve and optimize cognitive function as we move through life. I found her report that environmental toxins were one of the most common findings among her patient population illuminating. - DrKF

Targeting Senescent Cells? Dose and Timing Matters - with Dr. Greg Kelly

Thu, 28 Mar 2024 17:39:16 -0400
Get ready for a deep dive into the world of cellular senescence and its implications for aging. Dr. Greg Kelly joins me on New Frontiers to explain the science behind targeting this Hallmark of Aging and share natural compounds and activities that target cellular senescence. I am particularly excited for you to hear his thoughts around dosing and cyclical timing of exposure to senolytic compounds, such as fisetin, luteolin, quercetin, and piperlongumine, and why that may make the difference between having the effect you want... or not. Don't miss his advice on smart exercise tweaks for aging and the caution that overdoing it with exercise in our later years is much more harmful than it was in our twenties. Lots to unpack here.

Barry Sears (of Zone Diet Fame) on Lifetime Metabolic Health and Sourcing Omega-3s

Mon, 18 Mar 2024 17:24:27 -0400
I'm excited to welcome Dr. Barry Sears, the renowned creator of the Zone Diet and a pillar in our field. Dr. Sears has not only authored bestsellers but has also made incredibly important contributions to clinical practice which we still rely on today: He is, for instance, the scientist who put the use of the AA:EPA ratio on the map. Dr. Sears provides elegant and accessible explanations of the unassailable importance of diet in addressing inflammation, metabolic health, chronic disease, and longevity, and the role that fatty acids play in that milieu. And while he and I might not agree that polyphenols need to be absorbed intact for benefit - there's plenty of evidence that their postbiotic products are very important players, especially in their interactions with the epigenome - his concerns about the chemical structure of highly concentrated fish oil supplements (with the potential for isomerization, as he argues) has opened my eyes and is important, without doubt. I think the jury is still out as to whether there is a negative influence of isomerization in highly concentrated EPA and DHA, but it's worthy of further investigation and (importantly) is another factor in the argument for a whole-food approach. - DrKF

AI, Digital Twins, and the Future of Personalized Medicine Interventions with Dr. Nathan Price

Wed, 14 Feb 2024 20:29:03 -0400
Fellow clinicians, get ready for a mind-blowing conversation with Dr. Nathan Price, Chief Scientific Officer of Thorne HealthTech and author of The Age of Scientific Wellness. Imagine harnessing AI to predict outcomes of our functional interventions (diet, supplements, lifestyle) by implementing a “digital twin” model that is populated with all of your patient’s bio data. And being able to test the response of our treatments (and importantly, the synergistic response of multimodal interventions). It’s heady stuff, but amazingly, it is where we are headed today. Dr. Price illustrates the incredible potential this technology brings for personalized evidence-based medicine, such as tailoring interventions based on microbial markers or targeting specific lifestyle changes for Alzheimer's prevention. The podcast is a captivating exploration of cutting-edge concepts and provides a glimpse into the exciting future of healthcare. I was wowed by my conversation with Nathan and can’t wait to start kicking the tires on this baby. I know you’ll feel the same. ~DrKF Check out the show notes at www.drkarafitzgerald.com/fxmed-podcast/ for all the relevant links and resources.

Decoding Aging: The Science Of Cellular Rejuventation With Dr. Vittorio Sebastiano

Tue, 16 Jan 2024 17:40:24 -0400
It was a career-defining (and perhaps life changing) moment when Dr. Vittorio Sebastiano, a reproductive biologist by training, realized that because we are able to create life, that same body of information could be harnessed to create youth - that is, radically reverse our biological aging process to a younger time point without losing cellular identity. In 2014, he and his lab began unpacking this epiphany. They made the radical decision to conduct their investigations in human cells and tissue rather than in rodents, with the expectation that such a start would be a better bridge to human clinical trials. Flash forward a decade and Dr. Sebastiano and his team stand poised to begin trials in humans. Dr. Sebastiano is, in my opinion, one of the most extraordinary scientists in the longevity space today who flies under the radar of most of us in functional medicine. In this podcast - which is actually two-in-one because I continued the conversation with him on a second date - you’ll hear about the remarkable work they’re undertaking at his lab. For example: They’ve created a biological clock that encompasses the whole genome consisting of millions and millions of CpG sites. They are able to clearly demonstrate the reversal of bioage using their methodology - a cocktail of Yamanaka factors plus, with clear time limits - which changes the epigenome first, and in so doing influences all of the hallmarks of aging. Teaser: they’ve identified one intervention routinely used in clinical practice that influences their bio age clock in the same way that their cocktail does. What is it? I was riveted with this conversation, as I am sure you’ll be. Leave a review if you like it, and - Yes - let me know what you think. I know this will prompt deep questions for you, as it did for me. ~DrKF Check out the show notes at www.drkarafitzgerald.com/fxmed-podcast/ for all the relevant links and resources.

Burnout in Healthcare: Causes, Consequences, and Solutions with Dr. Jonathan Prousky

Thu, 07 Dec 2023 17:50:08 -0400
Working in healthcare brings a unique set of challenges and stressors. But the truth is that any of us can get to burnout through challenging circumstances of work or study. And the consequences can range from severe to devastating. Burnout still hasn't been fully understood or recognized by the medical profession and other industries - there is still no official diagnosis classification. Along with other mental health disorders, it is often still (wrongly) stigmatized and can even sometimes be seen as a "badge of honor," much to our detriment. Dr. Jonathan Prousky, Chief Naturopathic Medical Officer at the Canadian College of Naturopathic Medicine, joins me once again in this New Frontiers episode to explore the state of burnout in healthcare workers and beyond. Whether you work in our field or not, I guarantee you'll find it insightful. Together we explore the challenges we all face, and practical solutions to help you maintain your own health and well-being. As always, please feel free to share, comment, and rate - and let us know your thoughts on this important topic. ~DrKF Do You Think You Might Be Suffering From Burnout?

Harvard's award-winning Dr. Charles Serhan isn't just an expert on specialized pro-resolving lipid mediators (SPMs), he is the scientist who actually discovered them. His breakthroughs opened up a brand new field of research and clinical application with immense potential. After all, chronic, unresolved inflammation is a contributor or cause of so many conditions. The growing body of research on the utility of SPMs continues to astound (although when you start to understand the mechanisms, it's perhaps easy to understand some of the "why") - pain, rheumatoid, osteo- and Lyme arthritis, macular degeneration, periodontal disease, uveitis, surgical recovery, and repetitive head injury, for instance, have all been shown to be potentially benefited by the ability of SPMs to promote inflammation resolution. Clinically, I consider SPMs in all conditions where unresolved inflammation is a contributing factor. Not only that, but SPMs appear to have some rather surprising additional effects including stem cell regulation, tissue regeneration, and inhibition of amyloid-beta peptide in Alzheimer's models (even restoring memory loss in mice). I am honored to host Dr. Serhan here on New Frontiers along with his esteemed colleague, Dr. Megan Sulciner. Dr. Sulciner is a clinician-scientist and resident in the Serhan Lab whose exciting work focuses on advancing postoperative outcomes for surgical patients as well as the role of SPMs in enhancing cancer therapy and preventing cancer metastasis. I’m sure you will love this insightful, tour-de-force conversation! ~DrKF

Thu, 27 Jul 2023 18:10:57 -0400
Vascular health is fundamentally essential to longevity and health span, and that’s why I’m thrilled to be welcoming Dr. Michael Twyman to New Frontiers. Trained as an invasive cardiologist, Dr. Twyman has made the shift to a more preventative approach, moving beyond traditional cath lab results to focus on the health of the 60,000 miles of blood vessels that carry vital blood, oxygen and nutrients to every organ in the body, with hopes of reaching patients before they reach the end stages of disease. In this episode we’ll look at endothelial glycocalyx dysfunction as the root cause of cardiovascular disease, and dive into the key roles of nitric oxide, circadian biology, and the oral microbiome on cardiovascular health. I know you’ll find this interview to be absolutely fascinating. Have a listen and leave me a comment let me know what you think. ~DrKF

Evidence-Based Diet for Health and Stress Resiliency through the Microbiome with Dr. Vincent Pedre

Fri, 07 Jul 2023 18:24:38 -0400
I’m so happy to be here with Dr. Vincent Pedre to dig into emerging science on the microbiome. Dr. Pedre shares extensive clinical pearls from his vast experience in functional gut health in an approachable and fun way as he drills down on possible causes of the challenging gut epidemic we clinicians see in the increasing numbers of IBS patients walking through our doors. Dr. Pedre and I discuss how microbial diversity is the holy grail for reducing the risk of chronic disease, and how the gut disruptors of our time, (including food and environmental toxins, chronic stress, our over-sterilized world and lack of time in nature) are leading to many of the health challenges of the day. We get into current science on the impact of a high-fiber vs a diet high in fermented food on microbial diversity and immune activation. And there’s more: we talk about how where we live matters when it comes to our microbiome, the health- or disease-promoting post-biotics that are created, our optimal diet, overall health and our ability to create stress resiliency. It’s a lot -- and I’m sure you’ll be fascinated by Dr. Pedre and find numerous valuable insights to support your patients. Thanks for listening, and please leave me a review wherever you hear my voice. ~DrKF

Disrupting Anti-Aging Skincare by Targeting Senescent Cells

Mon, 05 Jun 2023 15:47:08 -0400
Imagine accurately determining the status of your skin’s age to tell whether it is younger or older than your chronological age, and then use this technology to determine whether expensive anti-aging serums and creams are effective, or actually causing more harm than good. Amazing, right? This is precisely the technology Dr. Carolina Reis Oliveira and her fellow stem cell biologists at OneSkin created and you will find this interview fascinating on so many levels – I know I sure did! After creating their skin clock, the OneSkin team discovered peptide OS1, which targets senescent cells, one of the root mechanisms of aging, and is being shown in current studies to have a positive effect on hydration, firmness, elasticity, and the skin barrier. Listen as Dr. Reis explains the science and ongoing studies exploring the possible benefits of OS1 for the skin microbiome, hair loss, inflammation, and overall health.

Optimizing Mitochondrial Health with Urolithin A, with Dr. Anurag Singh

Wed, 08 Feb 2023 18:30:20 -0400
I always appreciate talking to companies who heavily invest their time and dollars into preclinical and clinical science. And Timeline Nutrition, sponsor of this episode, is doing just that with dramatic results. They have figured out how to make a bioidentical Urolithin A, which compelling research has shown positively influences our mitochondrial health, with wide-ranging knock-on effects. In addition, since it relies on microbial formation from the right polyphenols within the gut, those of us without the right dietary precursors, or dysbiotic microbiomes, may not effectively produce it on our own. Please join me in this episode to learn more about the research and clinical applications of Urolithin A. And if you would be so kind, leave us a review and starred rating wherever you listen to New Frontiers! ~ DrKF

SPONSORED | Hydrogen Sulfide in Health, Disease & Longevity with Dr. Tom Fabian

Thu, 17 Nov 2022 09:00:09 -0400
In this New Frontiers in Functional Medicine® podcast, Dr. Tom Fabian delivers a well-justified challenge to our current thinking and a chance to build a more nuanced approach that will improve patient results around the topic of hydrogen sulfide, a compound that we have typically thought of as the “problem child” behind certain difficult SIBO cases. However, there is a LOT more to know about it, such as its ability to convert to potent antioxidant compounds, and its therapeutic roles in cardiovascular and metabolic disorders (diabetes and NAFLD), neurodegenerative disorders, and more. But how do we start to both broaden and nuance our approach to assessing hydrogen sulfide status? And what interventions can not only supply the substrates for beneficial hydrogen sulfide production, but also help achieve that all-important balance between too little and too much. Listen in to find out, and let us know what you think! ~DrKF

What to Do When Autoimmune Patients Fail Standard Elimination Diets

Mon, 07 Nov 2022 15:42:18 -0400
Functional medicine providers are well versed in addressing the myriad manifestations of autoimmune disease, but while our success rates are remarkably high, we still aren’t always able to help everyone using current toolsets (labs, sophisticated elimination diets, gut protocols, and so on). Enter Mymee, a digital app and coaching platform that helps plug that gap – this sophisticated tool helps identify elusive trigger foods and lifestyle factors that may still be contributing to an individual’s disease process. Mymee’s work with COVID long-haul patients and the Mount Sinai post-COVID treatment center (long-COVID is highly autoimmune-related) is impressive and especially relevant for clinicians and patients alike. Some fascinating patterns are emerging from their long-COVID patient data that feed directly back into how to approach these cases differently. I am sure you will find this as interesting and useful a conversation as I did! Please review New Frontiers wherever you hear my voice and let us know what you think! ~DrKF

SPONSORED | The Critical Role Telomeres Provide in Aging, Senescence, and Disease

Wed, 05 Oct 2022 19:07:57 -0400
It’s always a pleasure to tap into Dr. Raffaele’s brain, and in this podcast he doesn’t disappoint. In fact, his practical contextualization of where we are with anti-aging medicine might just be one of the smartest you’ve heard yet. What is truly remarkable about Dr. Raffaele is not just his grasp of the field both scientifically and clinically, but his ability to apply a nuanced approach that is tailored to each individual patient. After all, as he eloquently points out, we must first figure out which of the many components of aging needs improvement or correction, then target our approach accordingly. The simplicity of that statement belies his firm grasp of the complex landscape of anti-aging assessments and interventions, as you’ll see. One of the important topics that surfaced in our conversation is the role of telomere length. Dr. Raffaele has been measuring telomeres in study cohorts and in his patient population for well over a decade. Has looked at well over 2,000 telomere length measurements, many of them longitudinally. Not only that, but he has also integrated telomeres alongside other biomarkers of aging, including DNA methylation clocks, and tried-and-true metabolic markers such as lipids. So, if you thought newer approaches to biological age assessment were making telomeres and other assessments redundant, think again. We’re entering a time where we must wrestle with how to incorporate and act on all these important measures. ~DrKF

SPONSORED | Using Metabolomic Analysis For Clinical Insight

Tue, 05 Oct 2021 21:07:51 -0400
So many of us in functional medicine use standard organic acid interpretations, but newer research is using them in a broader metabolomics assessment (the vast landscape of clinically relevant metabolites). A great example is the assessment of in-born errors of metabolism. Utilizing metabolomics resulted in a six-fold higher diagnosis rate and identification of new in-born errors, compared to traditional organic acid assessment methods. Impressive, isn’t it? Think of what it could do in a full assessment. I’m thrilled to be joined by my dear friend and metabolomics enthusiast Dr. Betsy Redmond in today’s podcast. I worked with Dr. Redmond back at Metametrix and deeply admire her passion and skill in bringing metabolomics into clinical practice. With years of experience in functional lab testing and a doctorate degree in nutrition, Dr. Redmond shares exciting pearls from the latest metabolomics research, including using urinary dicarboxylic acids to identify early cognitive decline and strategies to modulate the kynurenine tryptophan ratio (KTR) – a novel biomarker associated with inflammation, cognitive decline, and kidney disease. I was excited to hear that this ratio could also be used as an innovative biological age marker – a topic at the center of my recently published study on reversing epigenetic aging, and focus of my book, Younger You. Thanks for listening to New Frontiers; please leave us a review and comment to let us know what you think! ~DrKF

Impact of Therapeutic Dietary Interventions on Disordered Eating

Sun, 01 Aug 2021 07:00:11 -0400
Therapeutic dietary interventions such as an elimination diet, a cardiometabolic diet, intermittent fasting, or caloric reduction, are some of the most important tools we have in functional medicine. Transitioning to healthful eating can for some patients be a joyous experience of liberation, but then for others it can be restrictive and problematic, and sometimes fall in the continuum of eating disorders. How do we tease this out? How do we screen for vulnerability in disordered eating and support patients who fall within this spectrum? In this episode of New Frontiers, Dr. Carolyn Fisher PhD, a licensed clinical psychologist who specializes in helping individuals with binge eating, emotional eating, chronic dieting, and other medical conditions heal their relationships with food. Today we discuss the importance of identifying disordered eating tendencies before guiding patients into dietary changes, tools to recognize those at risk, what is involved in treating eating disorders, and how to discuss weight in a sensitive manner with patients. This needs to be front and center in our minds, perhaps more now than ever, as we rely heavily on therapeutic dietary interventions to address chronic disease.

As a functional medicine clinician and scientist, I absolutely appreciate the deep literature dives my colleagues take. When they come up for air, there is a synthesized body of knowledge that is riveting, satisfying to listen to, trust-worthy and, most importantly, practice-changing. Such was my conversation on all things menopausal hormone therapy with Dr. Doreen Saltiel, currently consulting for Precision Analytical (they’re lucky to have her). She spent the bulk of her impressive career as an interventional cardiologist (although confesses she wanted to go into OBGYN) and jumped into integrative and functional medicine after her own “ah-ha” healing journey, involving hormone replacement therapy, relatively early on in her life. The first solid debunking Doreen provides are the findings from WHI. IT’S TIME these ideas are PUT TO BED. I asked Dr. S about the political backstory for the WHI debacle – it’s a good listen, and like me, you’ll probably want to read more. We then dive into the solid body of evidence for transdermal estradiol, oral progesterone. We discuss compounding, dosing, testing, addressing metabolites … and SO MUCH MORE. Keep a pen or your phone handy for note-taking, there’s tons of info in this podcast. Thanks as always, to Precision Analytical, creators of the DUTCH test, for bringing Dr. Saltiel to our listeners.

Understanding Genetics of Aging with Harvard Professor Dr. David Sinclair

Sat, 01 Aug 2020 09:00:06 -0400
Harvard scientist and NYT best-selling author David Sinclair, PhD and I take a tour around the science of aging. If aging is THE root cause of all of the chronic diseases of aging, then arguably, if we focus on the aging journey itself, we might be able to stop playing “whack-a-mole medicine.” A lot of complex environmental, genetic, epigenetic and biochemical processes go into the aging journey, however, as Dr. Sinclair discusses, it looks like a very heavy lifter in aging is epigenetic changes – specifically, DNA methylation and demethylation (plus histone acetylation). In this episode of New Frontiers, learn about the amazing research going on at Dr. Sinclair’s lab, hear what’s getting translated to humans, and what you can do NOW to stop the epigenetic clock from ticking…. Listen and learn, leave us a 5 star review if you’d be so kind, and be sure to share with your colleagues! ~DrKF

Making Functional Medicine Practice Accessible and Profitable with James Maskell

Fri, 03 Jul 2020 18:39:07 -0400
COVID19 is upon us. Months earlier, we scheduled James Maskell to discuss his recent book: The Community Cure. Amazingly, his message today is all the more urgent. James argues for the group visit model, was an early adopter and proponent of group visits (in fact, we discuss the pre-publication Cleveland Clinic group visit research findings, which are astonishingly good; even better than the first JAMA publication comparing functional medicine one-on-one with family medicine.) Now, with COVID19 and self-isolation, the virtual visit and the virtual group visit (where James saw FxMed eventually going) is upon us. And specifically, his vision is that this model works in insurance – and even Medicare. James’ message – the promise of functional medicine – is timely, inspiring, and essential. ~DrKF

SPONSORED | Panoramic Microbial Assessment: GI360 Stool Test with Dr. David Quig

Wed, 01 Jul 2020 20:15:48 -0400
The GI360 is a smart, evidenced-based stool test that is easily actionable by the clinician. Listen to my conversation today with VP of Scientific Support from Doctor’s Data, Dr. David Quig. One of the most useful tools I am aware of in stool testing is the Dysbiosis Test, which identifies and characterizes more than 45 targeted analytes across six Phyla using PCR and compares the patient results to a characterized normobiotic reference population. DDI is also using the Luminex PCR panel for pathogens, parasites and viruses – an FDA cleared panel for accurate detection of microbes that are almost always a problem. But what if they are not? Hear my discussion with Dr. Q on that. Finally, beta glucuronidase – it’s SO MUCH more complex than we’ve understood. Yes, we’re aware of the estrogen connection, but the BG story has evolved. We also walk through the chemistries – DDI includes a wide range of chems (appreciated by me and my colleagues here in our practice). Give us a listen, then leave a 5 star review and comment -- if you would be so kind! Thank you! ~DrKF

Episode 85: Essential Cardiovascular Risk Laboratory Analysis with Dr. Thomas Dayspring

Thu, 04 Jun 2020 18:44:45 -0400
What a superb conversation with leading expert lipidologist and – importantly – clinician of 30+ years, Tom Dayspring, MD. In this tour-de-force conversation, we break down the essential cardiovascular risk laboratory analysis you need to be undertaking on all your patients. We spend a little extra time on Lp(a) and the coronary calcium score. Our conversation is practical; I was fervently taking notes through the entire recording, as I suspect you’ll be doing. I will likely bring Tom back for additional conversation, perhaps focusing on women’s cardiovascular health, so stay tuned! As with many of my podcasts, I chat with my guests before and after the recording. Tom and I discuss on the podcast whether we’re concerned about brain cholesterol deficits with an excessively lowered LDL. He unequivocally stated not; we synthesize all the cholesterol we need locally, including in the CNS. However, after the recording, he added that statins can cross the BBB and lower brain cholesterol. Serum desmosterol is an analyte that can readily be assessed that is a surrogate marker of brain cholesterol: consider this if needed. Enjoy this in-depth conversation, and be sure to leave New Frontiers a rating on iTunes or Stitcher or wherever you listen. It’s the best thing you can do to help share this valuable content and help put FxMed in front of more and more listeners! Thank you! ~DrKF

Sponsored | Dr. Victoria Albina shares clinical use of CBD for anxiety and stress in patients

Tue, 02 Jun 2020 21:28:13 -0400
Globally, stress and anxiety levels have never been higher. According to one recent survey, a full 70% of Americans are stressed out, with a disproportionate impact on people of color. From worry about getting sick, to sick family members, to financial pressures, to homeschooling, the list of possible contributing factors is long. How do we care for our patients or clients in this climate? Victoria Albina, NP MPH is a family nurse practitioner in NYC – the COVID epicenter. She’s also a cognitive behavioral life coach and breathwork meditation facilitator. In short, she’s remarkably suited to walk us through tools to consider using with patients immediately. Victoria was an early adopter of using CBD for anxiety and has a wealth of knowledge around how to work with it for acute anxiety (regardless of how it presents: from insomnia to addictive “buffering” behavior). She also covers lifestyle interventions and key botanicals she’ll use concurrently when the need exists. And to top it off, Dr. Albina walks us through a lovely breathing exercise at the end of our conversation. It was one of the most grounding – and informative- podcasts I’ve done 😊, and I can’t wait to hear what you think. Leave us a review and 5-star rating on iTunes or wherever you listen to New Frontiers. Thank you! ~DrKF

Episode 83: SPONSORED | Ultimate Metabolomics Panel for Clinicians with Dr. Betsy Redmond

Tue, 19 May 2020 19:52:19 -0400
Many of us in functional/integrative medicine have used organic acid testing for decades to identify nutrient, toxin, and genetic imbalances. I am proud that the lab I once worked in developed one of the original panels – still quite popular and in wide use today. Inspiration for organic acid testing came from inborn errors of metabolism research, where a handful of compounds are (still) measured in newborns to rule out severe genetic diseases. Flash forward to the “Omics” revolution: you know, the genome, the epigenome, exposome, microbiome, etc. We’re beyond the 42 organic acids of old, and moving closer to clinical metabolomics. For me, it's about time, to be honest. Metabolomics in the research setting has been happening for years, and today I talk with Betsy Redmond, PhD, on the ultimate metabolomic panel for clinicians and what that might look like: actionable, straightforward, and evidence-based. Perfect for the busy clinician, and satisfying for those who want a drill-down into the biochemistry. Thanks for listening, and please leave us a review wherever you listen to New Frontiers! ~DrKF

The Tapping Solution: A Technique to Lower Cortisol and Reduce Stress with Nick Ortner

Tue, 05 May 2020 17:37:26 -0400
A nurse wakes in the night in profound anxiety, she can’t breathe, her first panic attack. Her husband is quarantined with COVID19; while she works the frontlines at a large hospital, witnessing what looks like the apocalypse. She begins a series of gentle, EFT Tapping exercises. After three brief rounds, she’s through the panic, able to once again relax. Nick Ortner is the CEO of The Tapping Solution, LLC, and my guest today on NFFM. Tapping is such a simple, elegant, immediate solution to the profound anxiety that comes with the out-of-control stress, fear and economic panic intrinsic in the COVID pandemic. With the Tapping Solution app (full access is available to healthcare providers for free), we can ground ourselves as needed. And for the data hounds among us (yes, that would be me); the app is tracking outcome. Over 1.5 million sessions have been conducted using the app. Regarding COVID19 specific exercises, Nick reports a couple of things: 1. Stress is at an all-time high 2. There is a daily average 45% reduction in the experience of stress after TAP exercises. You will enjoy this in-depth interview with Nick, and takeaway immediate tools to put to use for yourself and your patients. Let me know what you think, and please rate and review wherever you’re listening to New Frontiers.~DrKF

Episode 81: Sponsored | Optimizing Metabolism by Fueling the Microbiome with Dr. Alex Vasquez

Mon, 06 Apr 2020 20:54:04 -0400
Dr. Alex Vasquez has been teaching clinicians, publishing articles, books, and also edits his own journal – for decades. If you know Alex, you know he’s a bright light – highly regarded in our field. You may also know he’s struggled with a “tough gut” for years; in fact, this is what brought him to integrative medicine. From our years teaching together, I know Dr. V is diligent – profoundly committed, actually – to trying/vetting/evolving integrative protocols for gut health (botanicals, diets, pharma, fiber combinations, gentle, aggressive), often receiving small measure of benefit. He’s used various protocols with his patients, case studies he often generously shares when teaching. But here’s the thing: when Dr. Vasquez says he experimented for a long time on himself, creating and tweaking, over and over, a fiber-centric product that resolved his gut issues, we shut up and listen, do we not? So that’s what this podcast is about: talking about a wonder product, designed primarily by Dr. Alex Vasquez, that will likely revolutionize our approach to treating tough guts (think refractory SIBO, dysbiosis, inflammation, permeability, etc). Furthermore, it looks like this program will balance metabolic irregularities and address weight loss resistance – all very exciting! I had a great conversation with Dr. Vasquez on the origin and design, and science behind this new intervention. I would LOVE to hear how you like it, what kind of results you’re getting, and if you decide to try it on your TOUGH gut patients. Listen and learn from Dr. V, and please share with your colleagues, and leave a review wherever you listen to New Frontiers. ~DrKF

Traditional Chinese Medicine (TCM) for COVID-19 with Dr. John Chen

Wed, 01 Apr 2020 13:44:01 -0400
Traditional Chinese Medicine (TCM) is used in all settings in China for COVID19, with preliminary outcome data very, very strong. Indeed, outcome data using TCM for prevention and treatment of SARS Cov1 was equally strong. Listen to one of the most important and timely conversations I’ve had to date on New Frontiers with Dr. John Chen, one of the world’s leading experts in TCM (with western pharma training). Framing TCM in language clear for the Western-trained clinician, and translating the early descriptive language, Dr. Chen (author of the seminal textbooks used in all the TCM training programs in the US) is actively following TCM in China, and shares his experience, insight, and observations with all of us. An incredible, and timely, conversation, worthy of your utmost attention. ~DrKF Dr. Chen, author of the seminal textbooks used in all the TCM training programs in the US is actively following TCM in China

Episode 79: How The Wahls Protocol came to be, How to Launch Your Own Clinical Research Trial

Thu, 19 Mar 2020 17:17:15 -0400
We are all familiar with the Wahls Protocol. But how about the story behind the protocol? Did you know, for instance, that her director at U of Iowa (Terry is a clinician researcher) told her to write up herself as a case report? That was the first step. Her “N of 1”; then she wrote up a case series. Then she received a small grant and product for a slightly larger study. Then a million dollars. And now she’s heading into her largest study to date (yes, you will be able to refer patients). Listen to our New Frontiers conversation on how YOU as an FxMed clinician can contribute to the body of research demonstrating that: What. We. Do. Works. Terry and I also talk about behavioral change as THE MOST Important piece of the change journey. Hear how she supports it. This was by FAR one of my most treasured convos this year, and I appreciate you listening, commenting, giving us a 5-star review pretty please, and sharing with your colleagues! ~DrKF

Episode 77: The Secrets to Improving Patient Compliance with Dr. David Perlmutter

Wed, 12 Feb 2020 16:42:11 -0400
This interview was, without doubt, one of the most moving for me. What Dr. Perlmutter and his son, Austin Perlmutter MD, have created is really nothing short of a revolution in returning us to our consciousness. It directly addresses one of the biggest elephants in the room – despite what we know to be good for us, good for others, good for the planet, why do we more often than not fall short of putting that knowledge into action? We. Are. Disconnected. As a people. As a world. Our prefrontal cortex allows us to engage in reflection, empathy and good decision making. However, when we lose the ability to engage our prefrontal cortex, we regress to a more primitive part of our brain – the amygdala – which fosters impulsivity, narcissism, and anger. It is virtually impossible to make the choices that we want to when our amygdala is in charge. And as we make those poorer choices – poor diet, less sleep, less exercise, more screen time – we reinforce our amygdala’s superior position. It’s a vicious cycle. In short, our modern world stacks the deck against us. And what can we do? Dr. Perlmutter gives us a unique lens through which to work with ourselves and our patients to start to support that prefrontal cortex connection. Tips to start to re-wire our neuronal circuitry in ways that will help us all make better choices. Be better people. ~DrKF

Episode 75: Aging as an Evolutionary Program with Josh Mitteldorf

Sun, 01 Dec 2019 08:19:26 -0400
As FxMed docs, we’re committed to working with the body’s own capacity for health. Dr. Josh Mitteldorf offers a contrarian strategy, one which he says is grounded in a new breed of evolutionary medicine. He tells us that diseases of old age are qualitatively different from the diseases we get when we’re younger, different because in old age, our bodies are part of the problem, not part of the solution. Aging, says Josh, is the body deliberately destroying itself (for the sake of the population), via inflammation and apoptosis and autoimmune diseases. In this interview, Josh and I find common ground talking about hormesis. In Josh’s theory, the fact that the body lives longer when stressed (e.g. caloric restriction) is proof that the body isn’t trying its hardest to stay young when it’s not stressed. It may sound like philosophy, but there are real consequences for the future of medicine. These are challenging ideas, so I’m eager to hear what you think, and be sure to leave a review wherever you listen to New Frontiers! Thank you! ~DrKF

Episode 74: Sponsored | Innovations in Clinical Laboratory Testing with Dr. Michael Chapman

Fri, 01 Nov 2019 05:53:39 -0400
A work horse laboratory in any functional medicine practice is stool testing. But really gleaning the best insight into our patient’s clinical picture can be tough. What do all of these commensal organisms really suggest? How do they correlate with the inflammatory findings? Of the bell weather bugs (like akkermansia) how can we increase levels? Is there ANY place for microscopy (O&P) and culture in today’s high throughput Omics world? You see where I’m headed. Even for the most seasoned FxMed clinician, a review of how to use these tests with an eye towards what to expect in new technology is essential. Disagreement with methods? Yes. Why? Zonulin Family Peptide – any utility? A great conversation with Dr. Michael Chapman of Genova Diagnostics. Thrilled with their commitment to in-house “data mining” and peer reviewed publication (IMO all of the Fx labs should be doing this). ~DrKF

Episode 73: Making Sense of the Microbial Ecosystem with Dr. Marvin Singh

Fri, 01 Nov 2019 05:52:48 -0400
Marvin Singh, MD is a practicing gastroenterologist with a focus in personalized lifestyle medicine. I met Marvin in 2017 when I was asked to submit a chapter to Oxford University Press Integrative Gastroenterology, 2nd Ed. Marvin has been coediting this behemoth with my IFM colleague Gerry Mullin, MD. (Full disclosure: very large props must go to Nikky Contractor, PhD for the heavy lifting on our chapter). Marvin’s evolution from a very traditional, academic gastroenterologist to integrative gastroenterologist to a cutting-the-edge personalized lifestyle medicine doctor (folded inside his own healing) is a story I think you’ll find interesting, and relatable. As we move through his story, I ping Dr. Singh on labs, interventions, books, all sorts of content – lots included, be sure not to miss this one. Brilliant guy, and I ‘d love to hear what you think! Be sure to rate, comment and review New Frontiers, wherever you listen to the podcast – I so appreciate you listening! ~DrKF

Episode 72: Nocturnal Hypoglycemia & Continuous Glucose Monitoring: the amazing Dr. Sara Gottfried

Tue, 08 Oct 2019 18:48:57 -0400
By far one of my most wide-ranging conversations on New Frontiers, Dr. Sara Gottfried and I set out to talk about her new book Brain, Body Diet and quickly headed north. Listen to our lively, personal, smart, heart-felt conversation as we dive into her experience using a continuous glucose monitor to address fairly severe nocturnal hypoglycemia, her thoughts on addictions and genetics, taming the dopamine-deprived COMTer, and lots of women’s health. You know that Sara is, of course, extraordinarily bright, but she’s also an open book in a lovely, inspiring way. For instance: How would a concussion, obtained through a dearth of self-care plus wine, lead to the Brain Body Diet? Besides the obvious connection, Sara describes a personal reckoning and rebirth that I can certainly relate to.

Episode 71: SPONSORED: Cornerstone Interventions for GERD with Victoria Albina

Wed, 02 Oct 2019 20:23:37 -0400
Take a second and think about this: what clinical presentation would prompt you to prescribe cognitive behavioral coaching, breathwork or meditation? Did GERD make your list? Along with gentle, but powerful botanicals and nutraceuticals (IT’s Motility Activator, DGL Chewables, Heartburn Advantage), these are cornerstone interventions for GERD in the practice of Victoria Albina, NP, MPH. Victoria operates from a patient empowerment position, believing that it’s essential for lasting change in a ubiquitous lifestyle condition such as GERD. We also cover epidemiology (30% incidence in the US), root causes, laboratory—and really interesting to me—the variable clinical presentations GERD can take. Finally, are PPIs .. safe? Victoria discusses a recent study that made the PR rounds. Take a listen, and be sure to like, comment and rate the podcast in iTunes, Spotify, or wherever you’re hearing my voice. Thank you! ~DrKF

Episode 68: What’s the deal with Lectins and Autoimmunity? with Dr. Datis Kharrazian

Thu, 29 Aug 2019 11:17:26 -0400
If you’re practicing functional medicine, you’re aware of (and likely prescribing) the autoimmune paleo diet, pulling folks off of many foods, lowering carbs, reducing or eliminating lectins (and nightshades). In this terrific podcast with Dr. Datis Kharrazian, we talk about his research in stratifying who’s who with regard to autoimmunity. For example, Dr. K suspects that very roughly about 30% of his autoimmune patients are truly lectin sensitive; they tend to be those with arthritic musculoskeletal autoimmunity, most classically, RA. For many of these folks, lectins must be eliminated. However, lectin/nightshade elimination may not be required for, say, Hashimoto’s; although there IS a collection of potential cross reactive foods that could play a role in promoting antibody production (and removing will reduce ab production)….

Episode 69: SPONSORED Telomere Integrity: What Clinicians Need to Know with Dr. Joseph Raffaele

Thu, 29 Aug 2019 11:15:02 -0400
Are you thinking about age management with your patients these days? I am. And I’m thinking about it regarding myself, quite frankly. To that end, I just had a tour-de-force conversation with clinician researcher Joe Raffaele, MD. Can we halt, or even reverse, the biological aging process? There are an extraordinary number of variables to consider here, but the take-home appears to be YES. Of course, FxMed is our foundation, but layer onto that telomere biology, and telomerase activation using innovative approaches such as the astragalus-derived molecule like the one found in TA-65, and some pretty impressive outcomes are possible, as we discuss. With over 5000 “N of 1’s” in his database, and principle investigator of a number of published clinical trials, Dr. Raffaele has plenty of experience on how we want to be addressing (and measuring) the aging journey. Generally, lifestyle interventions – such as those we’re doing in FxMed – will slow biological aging. But what about HALTING or even REVERSING biological aging? Listen to our convo on New Frontiers, and PLEASE be sure to comment and share wherever you listen to the podcast, and let us know what you think! ~DrKF

Episode 67: Functional Medicine Pediatrician Dr. Elisa Song on PANS/PANDAS DX and Treatment

Sat, 13 Jul 2019 09:12:50 -0400
In this podcast of New Frontiers, I’m talking with Dr. Elisa Song, a functional medicine pediatrician and superb teacher. If you are practicing FxMed, you’re probably seeing more and more kids if your scope allows (even if you didn’t before). Kids need FxMed, yet there are arguably LESS pediatricians transitioning into FxMed than other disciplines. Thus, working with kids can come with questions – labs, dosing interventions. Listen as Dr. Song and I gallop through loads of foundational information (and we’ll provide more down the road – a blog, another podcast – we’ll see) as this is a huge, important area for us. Here, the bulk of our time on New Frontiers is on PANS/PANDAS: how to identify, and what to do. Both are forms of infection-triggered autoimmune encephalitis. Take a listen, and be sure to comment on iTunes or wherever you’re listening. I’d love to learn your thoughts! ~DrKF

Episode 66: SPONSORED | New Hope for Fibromyalgia Patients with Erik Lundquist, MD

Mon, 08 Jul 2019 16:26:52 -0400
As a clinician interested in participating in research, it’s very exciting to see others jumping into the research conversation, too. Today I talk to Dr. Erik Lundquist, who heads a large, integrative clinic out in Southern California. Erik recently completed a clinical pilot study looking at the use of SPMs (just 2 gelcaps per day) in patients diagnosed with fibromyalgia (Dr. Lundquist reports that the bulk of these patients have underlying mold exposure or Lyme as the primary etiology for FMS). While labs and pain scores didn’t improve markedly in the population, there was a clear, statistically significant jump in quality of life for these folks. In fact, Dr. L suspects that the increased movement and engagement in life probably influenced the lack of drop in pain. And further, Dr. L pointed out that standard labs such as CRP were NOT elevated at baseline in the chronic mold/Lyme population. Listen to the details, and Erik’s story. If you are wanting to participate in clinical research yourself, I’d love to hear about it, and, as always, I appreciate you listening and ask that you please rate, comment and share New Frontiers with your colleagues! ~DrKF

Episode 65: Bacteriophages in the age of antibiotic resistance - Drs. Paul Turner and Benjamin Chan

Fri, 14 Jun 2019 14:14:21 -0400
Once upon a time, in a pre-antibiotic world, bacteriophages were a hot research topic in this country and elsewhere. In the 1940’s, Eli Lilly had seven OTC bacteriophage products available – good for everything from abscesses to URIs and mastoiditis. However, with the advent of antibiotics, the research into and use of phages ceased in the US. But in the age of antibiotic resistance, we’re back at phage research, and its wildly interesting and extremely important to explore. Phages are bacterial viruses that invade and kill bacterial cells: an obvious answer to antibiotic resistance. Listen to my conversation on New Frontiers with phage scientists Paul Turner and Benjamin Chan of The Paul Turner Laboratory at Yale University, get the background on all things phage research, and hear a handful of inspiring case reports from “pond to bench to bedside” as Drs. Turner and Chan like to say. Sit back and listen to this terrific podcast, and be sure to comment on iTunes, share with your colleagues, and let me know your thoughts! ~DrKF

Wed, 12 Jun 2019 09:20:22 -0400
Compounding pharmacies: SO essential to the FxMed clinician’s toolkit. Compounding individualized prescriptions are at the heart of what we do, and on this podcast of New Frontiers, I am delighted to talk to Michelle Violi, Pharm. D, of Women’s International Pharmacy. Located in Wisconsin and Arizona, but serving clinicians and patients everywhere, WIP has been compounding bioidentical hormones for decades. Join our conversation, where we cover the background of WIP, their commitment to education (patients and clinicians; how to access), regulation of compounding pharmacies (its rather extraordinary), how to pick a good compounding pharmacy (check for PCAB status), and of course, we talk about hormones, too.

Episode 62: SPONSORED Methionine Metabolism and Methylation with Dr. David Quig

Mon, 06 May 2019 17:29:26 -0400
I enjoy discussing all things nutritional biochemistry, and few minds are more engaging to chat with than David Quig, PhD, VP of Scientific Support at Doctor’s Data. In this NFFM podcast, we’re drilling down into the laboratory assessment of methylation and sulfuration. As Dr. Quig makes clear (yet again)--- while we might make some *basic* inferences around methylation activity by looking at a person’s SNPs, SNPs are not our destiny (thank God!). Ultimately, SNP assessment doesn’t hold a candle to direct assessment of key methylation intermediates. And indeed, we often find our biochemistry- i.e. what is actually happening in the body at any given time—is very, very different from what our SNP patterns suggest we might find. You’re going to want to hear what he has to say, so settle in because you’re going to learn a lot. And you’re not going to want miss the valuable downloads in the shownotes! ~DrKF

Episode 61: Must-know Causes for Refractory Sibo with Dr. Steven Sandberg-Lewis

Tue, 23 Apr 2019 17:39:31 -0400
A huge, constant question we get from clinicians and patients is: what to do about refractory SIBO? Patients want hope, clinicians want to successfully resolve… Listen to my podcast to discover what one of the greatest minds thinks about all this and more. Dr. Steven Sandberg-Lewis, co-founder with Dr. Allison Siebecker of the National University of Natural Medicine SIBO Center – one of only four centers in the US dedicated to diagnosis, treatment, education and research, is a longtime naturopathic physician and perennially popular professor of gastroenterology at NUNM. In this NFFM episode, DrSSL covers less commonly explored reasons for SIBO, including hiatal hernia syndrome, ileocecal valve syndrome, adhesions & scar tissue and hypochlorydria. Learn signs/symptoms (often unexpected), diagnosis and treatment for these all-too-often missed underlying issues. FYI – great downloads in the shownotes too – the “common causes of SIBO” PDF is essential, IMO. Be sure to rate, like, comment, and share our podcasts! Thanks always! ~DrKF

Episode 60: SPONSORED: Dutch™ Research and Validation in Peer-Reviewed Journal

Fri, 19 Apr 2019 20:17:35 -0400
What’s the best way to test hormones? That is the key question that drove Mark Newman to create the DUTCH test. DUTCH stands for Dried Urine Test for Comprehensive Hormones and it gives clinicians a robust picture of a patient’s hormone levels and functioning. DUTCH tests are used by many leading functional medicine practitioners, including hormone expert Sara Gottfried, MD. Here, Dr. Kara Fitzgerald talks with Mark Newman about the advantages of using the DUTCH test, the strengths and limitations of lab testing in general, and how to interpret results. If you’re a clinician who relies on lab testing in your practice, you won’t want to miss it.

Mon, 04 Mar 2019 17:36:04 -0400
Lyme disease (and co-infections) can be tough to treat. The Lyme spirochete, Borrelia burgdorferi, has adopted loads of devilishly clever cloaking devices – from thriving in biofilm to existing in pleomorphic forms – to ensure survival despite aggressive treatment. Enter botanical therapy. With or without concurrent antibiotics, botanical combinations are an essential component of the FxMed clinician’s toolkit.

Wed, 13 Feb 2019 15:55:59 -0400
DSL’s GI-MAP stool test is, as CEO Tony Hoffman states, “a clinician diagnostic tool;” it’s not a microbiome test. Yes, of course the GI-MAP looks at the microbiome, but it's not a broad sweep of the myriad of bugs taking up residence. Rather, it’s a carefully curated investigation of organisms with demonstrated imbalance potential, be it pathogenic or dysbiotic in nature. The test is designed to be user-friendly, interpreted rapidly, logically, providing clearly actionable data that, when addressed, gets results. I’ve known Tony for years; we were both involved in the development of the first stool test using PCR analysis offered to clinicians. He’s brilliant, fun to listen to, and offers loads of pearls in this conversation. Take a listen, share, comment, and let us know what you think!

Episode 57: The Future is Great with Medicinal Mushrooms with expert Jeff Chilton

Wed, 13 Feb 2019 15:55:47 -0400
A wide body of research—not to mention centuries of use in Chinese medicine—has shown the power of medicinal mushrooms in promoting health, and no one knows more about the cultivation, manufacture, and distribution of supplemental mushrooms in modern integrative health care than Jeff Chilton. The president of Nammex, one of the biggest medicinal mushroom extract companies in the nutritional supplement industry, Jeff talks with Dr. Fitzgerald in this episode of New Frontiers about how mushrooms are grown and cultivated (and why that matters for supplement quality) and how clinicians and consumers can tell if mushroom supplements contain any actual medicinal value or not.

Episode 55: Plant Medicine, Photonutrients, and the Health Benefits of Eating a Rainbow

Wed, 09 Jan 2019 09:10:58 -0400
Dr. Deanna Minich preaches: Eat a rainbow. Why? There are over 700 carotenoids found in plants – all bioactive, and generally pleotropic (ie: they do more than one thing in the body). We don’t need tons of any single carotenoid, and indeed – if anyone recalls the beta carotene smoker study from the early 2000’s, too much of a single compound could arguably be toxic. But variety is essential. And amazingly, certain groups of carotenoid colors favor certain organs. Think “orange for ovaries”; blue for brain and green for heart. Listen to my riveting conversation with Dr. Deanna Minich as she shares her own healing journey from endometriosis and how color, plant medicine and spirit converged…. carotenoid science to artist. Variety. ‘Bridging the gap between science, soul and art’ in medicine. And hear about the Scio and how you can test your food nutrient density in this cool, cutting edge, handheld device – and loads MORE! There are 25,000 plant phytonutrients that we are aware of, and probably many, many more that we are not. Listen to this revealing podcast with the incredible Dr. Deanna Minich, and be sure to comment, give a thumbs up, and share with a friend!

Episode 54: SPONSORED Non-Alcoholic Fatty Liver Disease: Dr. Robert Rountree shares his Expertise

Thu, 03 Jan 2019 19:14:57 -0400
Non-alcoholic fatty liver disease is an urgent, often unrecognized concern. It’s the hepatic pandemic of the 21stcentury, and there is NO approved pharmaceutical therapy (the race is on, however…). Fortunately for us, there is MUCH we can do in functional medicine – indeed, our toolkit is powerfully effective in turning around NAFLD and even NASH – the next step progression. Listen to my conversation with my good friend and longtime colleague Dr. Robert Rountree (finally on NFFM!). Bob outlines the scope of the problem (did you know 80% of obese kids are at risk?) how to evaluate for it, and most importantly: what to do. This was such a content-dense discussion, I am most grateful Bob has made his full powerpoint deck available to you for download. Take a listen to the podcast, then circle back to the deck for all the specific details on what to do.

Episode 53: SPONSORED From Biological Plausibility to Clinical Efficacy w Food Sensitivity Testing

Fri, 07 Dec 2018 14:00:35 -0400
Dr. Joel Evans – you probably know him as long-time IFM faculty teaching in the Advanced Practice Hormone Module. He’s also donned a newish hat as KBMO’s Medical Director. Dr. Evans loves the FIT test for delayed hypersensitivities to foods, and states that the addition of complement fragment C3d to their test significantly reduced the incidence of false positive results found on standard IgG testing. Listen to our convo on the FIT test, how he’s using it in practice, who he uses the test on, and why its essential in preconception planning. Also: this just in! We’re the first to hear about his study using KBMO vs healthy diet on 100 individuals with IBS – get the outcome data here.

Episode 52: Ground Zero for Gut Health: Probiotics, Microbiota Manipulation and Dr. Jason Hawrelak

Wed, 05 Dec 2018 10:26:50 -0400
The centrality of gut health in overall health cannot be overstated, and for many years researchers and practitioners have encouraged probiotic use to promote gut health. But their recommendations have been based on early and inchoate research. Today, several decades after the emergence of gut health as the ground zero of overall health, science has been able to correlate specific bacterial strains with specific health outcomes—and one man has spent years anthologizing all that research and making it available to practitioners and patients. Dr. Jason Hawrelak is a scientist, educator, and naturopathic physician. He’s one of the leading experts in microbiota manipulation and the use of specific strains for specific conditions. He is also the creator of probioticsadvisor.com, where practitioners and patients can access information about specific bacterial strains. Check out my conversation with Dr Hawrelak on NFFM. I am thrilled to be introduced to his work (have referred folks to him already), and so appreciate his dedication to crunching the data for us clinicians on Probioticadvisor.com.

Episode 51: All things Mast Cell with World-Renowned Clinical Researcher Dr. Theoharides

Tue, 20 Nov 2018 11:29:29 -0400
In my Tour de Force conversation with the brilliant Dr. Theoharis Theoharides, we covered all things mast cells, from “bench to bedside.” In case you have not yet encountered his work yet, he is one of the most highly decorated, well-published clinician researchers in the world. The focus of his life’s work has been on all things mast cells, and mast cell associated conditions. Given the meteoric rise in said conditions (and our improved understanding of the role of mast cells in most chronic diseases), as clinicians, we need to understand how to diagnose and treat. Buckle up for this podcast, and get your pen and pad ready – the depth and breadth of Dr. T’s knowledge requires careful listening. Give a listen, then give a thumbs up for this brilliant, generous clinician!

Episode 50: SPONSORED Multi-mechanistic approach to treat anxiety & depression w Dr. Corey Schuler

Fri, 16 Nov 2018 16:28:10 -0400
Some of our most popular podcasts have been with Dr. Corey Schuler: he’s down-to-earth, practical in his approach to patient care, and very evidence-informed. And today is no exception! Join me and Corey as he talks through his “4 Pillar” approach to treating anxiety and depression. He discusses the multifactorial biochemical underpinnings of both conditions, his assessment tools (including labs), treatment (for acute presentations, chronic and co-managing those on pharma) and expectations of outcome. You won’t find the usual arsenal of natural therapeutics in Corey’s approach – he rarely uses 5HTP or St. Johns Wort – rather, he starts with full functional medicine and drills down into his 4 Pillars to determine next steps. We chat on new research – I think you’ll be impressed – and citation links are in show notes – including a recent study on Theracumin for memory and mood. Give us a thumbs up, leave a comment, and let us know what you think! ~ DrKF

Episode 49: SPONSORED Prescribing bioidentical hormones using DUTCH test w Dr. Lynne Mielke

Mon, 29 Oct 2018 16:25:02 -0400
It’s not often that I get to spend an hour chatting with a busy clinician on pearls learned over years of practice. In today’s podcast, I’m talking with long time integrative medical clinician and anti-aging expert Lynne Mielke, MD about her approach to bioidentical hormones and why the Precision Analytical DUTCH is her preferred test for assessing HRT response. It’s her experience that the “gold standard” blood tests often lead to over-prescribing, and she commonly finds herself initiating tapers for those patients who come to her already on biHRT. Lynne also shares with us her journey to integrative medicine- as a psychiatrist, she faced the limitations of her training when her son was diagnosed with autism. As she puts it, she entered another world as she dove into integrative, biomedical treatments for autism decades ago: “Given the complexity of spectrum disorders, If you know how to treat them, you know integrative medicine.” From there, she leaped into anti-aging medicine, as parents of autistic children sought her care. Dr. Mielke discusses her transition into practicing integrative medicine, and what her clinic looks like today. ~DrKF

Episode 48: Mastering Diabetes with Dr. Mona Morstein

Mon, 01 Oct 2018 12:44:57 -0400
Dr. Mona Morstein has focused the bulk of her career on treating all types of diabetes (DM). In late 2017, she published the a superb 500+ page very well-referenced book on the topic, titled Master Your Diabetes: A Comprehensive, Integrative Approach for Both Type 1 and Type 2 Diabetes. Despite written in layman language, clinicians will find it meaty enough to be useful in practice – I especially like the sections on DM complications. In our conversation, we look at the four main types of diabetes, discuss etiology and epidemiology of types 1 and 2. We discuss standard labs, including the limitations of A1C, and the utility of the GlycoMark test. Learn how she does a glucose/insulin tolerance test and specialty lab testing considerations in patient management, managing the microbiome, intestinal permeability, food sensitivities. Diets: Dr. M recommends a very low carbohydrate diet (VLCD), but we had a great sidebar convo on the paradox of VLCD and vegan macrobiotic diets demonstrating equally good outcome – learn why Dr. Morstein suspects that is. Toxins, particularly POPs, but also metals, play a huge role in ushering in diabetes – learn how she’s evaluating and treating. We discuss nutraceutical interventions, medications – what she’s using and why. Of course, no conversation on DM is complete without discussing the influence on lifestyle. An interesting point Mona makes is that the program of treatment must be doable and relatively stress-free. Please give this terrific podcast a thumbs up and share if you like it as much as I think you will, and as always, let me know your thoughts!

Episode 47: Dr. Stephen Sinatra and the Past, Present and Future of Integrative Cardiology

Tue, 04 Sep 2018 12:22:35 -0400
If you’ve listened to my podcasts, you surely know that I love what I do. And my podcast with Dr. Stephen Sinatra is no exception. One of my most inspiring conversations to date, Dr. Sinatra is, as you know, a pioneer in the field of integrative cardiology. Hear about his remarkable, very early transition to integrative cardiology, including pivotal encounters with patients and scientists that shaped his thinking; his gutsy, hospital grand rounds presentations on the use of CoQ10 for heart failure patients, and the story of my mom working as a cardiac nurse with him during his fellowship. While Sinatra doesn’t maintain an active medical practice anymore, he still goes into his office often “to see how my former heart failure patients are doing. I don’t charge them. I just want to check in” He talked about a 9 year old boy he saw with florid heart failure. That boy is 32 years old now, and doing great. He was involved in designing the treatment plan for the now oldest-living person with tetralogy of Fallot. What did he prescribe? The “fearsome foursome”: CoQ10, magnesium, ribose and carnitine. At 73 years old, the first heart failure patient he prescribed CoQ10 to (10mg TID!) is alive and well. We move through loads of research on nutrients (yes, we discussed K2) diets, fats and what we need to be doing for ourselves, our families and our patients. Update: Dr. Sinatra and I spent a chuck of time on the famous PREDIMED study, published in the New England Journal of Medicine in 2013. PREDIMED garnered much attention by validating the use of a Mediterranean diet supplemented with olive oil or mixed nuts for reducing incidence of cardiovascular disease in persons at high risk. Interestingly, the day we recorded, news broke that the PREDIMED was retracted. However, the study authors re-published the PREDIMED in NEJM June, 2018 with compromising data omitted. The findings remained similar to the original PREDIMED. Listen to Dr. Jeff Bland discuss the details.

Episode 46: SPONSORED Endotoxemia: The Underlying Reason Most of Your Patients Need Immunoglobulins

Wed, 25 Jul 2018 17:27:56 -0400
Endotoxemia. A fundamental driver of chronic disease. What is it? And more importantly, what do we do to address it? In my podcast with Dr. Jill Carnahan this month, she unleashes a torrent of compelling science and clinical savvy on all things endotoxemia. From heart disease and diabetes to autoimmunity (genetic or acquired) and mast cell activation, Dr. Carnahan is clear that pathological intestinal permeability (she discusses testing, but at this point in her career believes most everyone who sees her with chronic disease has IP) drives inflammation by allowing excess microbial endotoxins- primarily as lipopolysaccharide (LPS)- to enter circulation. Focused on root cause functional medicine (toxins, diet, infection, genetics), she concurrently heals the gut to drop the inflammatory burden. A key intervention for Jill is sugar-free, GMO-free, serum-derived bovine immunoglobulin (SBI), and we spend quite a bit of time on why SBI is crucial. With 43 human trials behind it, if you are not using SBI yet, you’ll be compelled to start, I suspect. We also have a fun dialogue on the role of fatty acids and toll-like receptor activation, connected directly to LPS. Jill shares a handful of very compelling case vignettes AND talks candidly about how she set up an extremely successful functional medicine practice and positioned herself as an expert in the field. And let me know: will you be changing how you prescribe high fat diets based on the research we discuss?

Episode 45: Acupressure Tapping in Clinical Practice - A conversation with Jessica Ortner

Tue, 24 Jul 2018 11:30:58 -0400
Anxiety can get in the way of patients achieving their health goals—especially when a practitioner recommends significant lifestyle and nutrition changes. Patients may feel suffocated by the new regimen and then make changes for a while but revert back—or they may not make them at all. The Emotional Freedom Technique, also known as tapping, can help patients ease anxiety and better achieve their health goals. It can also help with the subjective experience of pain or be used in service of a specific health goal, like overcoming weight loss resistance. In this podcast, Dr. Fitzgerald talks to Jessica Ortner, author of The Tapping Solution for Weight Loss & Body Confidence, about how tapping could help patients in a functional-medicine clinic setting. And, together, they walk step-by-step through a round of tapping so listeners can hear how it’s done (and follow along).

Episode 44: The Lyme Solution: A conversation with Dr. Darin Ingels

Thu, 28 Jun 2018 12:30:38 -0400
After suffering through a lengthy Lyme infection himself (with classic presentation), which initially responded to antibiotics but didn’t resolve the infection, Dr. Darin Ingels went on a years-long quest to recover, returning to naturopathic principles and discovering essential less-used protocols. The results are in his book: The Lyme Solution: A 5-Part Plan to Fish the Inflammatory Autoimmune Response and Beat Lyme Disease (Penguin Random House), and he has been treating patients with Lyme and co-infections successfully since then. In this clinical pearl dense podcast, Dr. Ingels pulls from his experience as a clinical microbiologist by training, to share what he is doing today in practice – from labs that work and those that don’t, using immunotherapy, the association with mold allergy and mycotoxicity, to botanical protocols and when to use antibiotics. While he doesn’t use the word “functional,” it’s clear that his approach to Lyme embraces a full functional approach, and that addressing the whole person, and their environment, is essential to recovery.

Episode 43: Fasting Mimicking Diet: Beyond caloric restrictions with Dr. Valter Longo

Fri, 08 Jun 2018 11:05:07 -0400
Wow! What a great conversation with Dr. Valter Longo, director of USC’s Longevity Institute. It’s always exciting to talk to someone in the trenches of bench and clinical research, especially a rock-star like Valter Longo! You can hear my nerves as we begin ☺, yet there’s much to learn about Dr. Longo’s journey from a Blue Zone upbringing in Italy to music major to biochemisty major to leading expert in articulating the biochemical and genetic underpinnings of the aging process. Dr. Longo was a post-doc under Dr. Roy Walford – famous for his research on caloric restriction and longevity. While Walford’s work – famously the 2-year Biosphere study conducted on humans – yielded remarkable improvements in chronic diseases, there were many side effects. The limitations of the human Biosphere study prompted Dr. Longo to turn his attention to longevity in single-celled organisms (S. Cervascie, specifically), then animal studies, and most recently humans. Longo designed his short term fasting mimicking diet (FMD), which does away with the fallouts he observed in long term caloric restriction. We cover a lot of great material in this conversation – and Dr. Longo makes compelling points against the unfettered use of MCT and exogenous ketones. Take a listen and let me know what you think!

Episode 42: SPONSORED Unlocking the potential of endocannabinoid system w Dr. Jacqueline Jacques

Wed, 16 May 2018 10:16:44 -0400
Yes, hemp & marijuana are major providers of cannabinoids, and in the FxMed space, we are extremely excited about this potent family of bioactive molecules. In particular, we are looking at CBD for indications ranging from pain to mood, inflammation, memory and more. Turns out the endocannabinoid system (ECS) extends body-wide, and similarly, phytocannabinoid sources extend far beyond hemp and marijuana. Listen to my conversation with Dr. Jacqueline Jacques, Senior VP with THORNE – and tour the ECS and the use of phytocannabinoids from hemp, rosemary, clove, black pepper and even hops, whose constituents have an “entourage” effect on the ECS, along with other commonly prescribed compounds including diindolylmethane, ginseng, echinacea. It strikes me as extremely logical we’d be thinking about using phytocannabanoids with most of our patients and ourselves – probably PCs are foundational interventions not dissimilar to the regularly prescribed essential fatty acids. We get the inside scoop on all this and more in New Frontiers! Take a listen and let me know what you think:

Episode 41: Food: What the Heck Should We Eat with Expert Dr. Mark Hyman

Sun, 06 May 2018 00:00:00 -0400
In my conversation with Mark Hyman on his new NYT best seller, Food: What the Heck Should I Eat?, we discuss the myriad challenges consumers face in figuring out the correct diet, but also, what WE as clinicians caring for patients – what do we prescribe? What do the data show? Are grains really verboten? Is dairy completely off-the-plate? What about meat? And fats/cholesterol and the APOE4 patient? Mark enlightens me to the new “regenerative agriculture” movement; going far beyond organic, regenerative agriculture regenerates the environment while providing good, clean food. Amazing, right? He also addresses the common price complaint. What is the cost of eating clean vs eating conventional? We also go behind the scenes to address the insidious agribusiness at the heart of US policy, and chat about Steven Savage’s recent take-down of Environmental Working Group’s Dirty Dozen Clean Fifteen lists. This was such a fun convo for me, and as always, Mark is doing great detective work getting to the heart of concerns around diet and the ecology of eating. Take a listen, I bet you’ll be as intrigued as I was.

Episode 40: The Epicenter of Epigenetics; Discussing the Agouti Mice Study with Dr. Randy Jirtle

Thu, 12 Apr 2018 11:27:58 -0400
I am thrilled and honored to podcast with Dr. Randy Jirtle. The field of epigenetics has exploded in the last decade, initiated almost exclusively by the groundbreaking research of Randy and his colleague Robert Waterland. Their 2003 study on the effects of nutrition on epigenetic gene regulation in agouti mice is the most cited paper in the history of science, and his trailblazing discoveries have expanded our understanding of human health and the etiology of disease. Listen to my fascinating conversation with Dr. Randy Jirtle.

Episode 39: SPONSORED: Scientific Serendipity: Beautiful Bio-Botanicals with Dr. Rachel Fresco

Fri, 06 Apr 2018 10:33:38 -0400
A lot of scientific discoveries are borne out of serendipitous moments where a brilliant idea and unmet need collide. Such is the case with one of my all-time favorite “workhorse” botanical combination products, Biocidin. Listen to Dr. Rachel Fresco, founder and president of Bio-Botanical Research, talk about the story of Biocidin, the decades of interesting and on-going in-vivo and in-vitro research, and loads of clinical reports demonstrating efficacy. Also hear about Bio-Botanical’s suite of other no less creative products, including Oliverex, Proflora4R and GI Detox. In my practice, Biocidin is a work horse botanical combination I use ALL the time. It’s well-tolerated, and being a liquid formulation, I can dose low and slow or high and aggressively as I need to. Listen to my conversation with Dr. Rachel Fresco here!

Episode 38: SPONSORED HPA, Organic Acids and the DUTCH Test with Dr. Carrie Jones

Wed, 21 Mar 2018 18:05:52 -0400
Why would Precision Analytical, the laboratory famous for the ground-breaking DUTCH test (Dried Urine Test for Comprehensive Hormones) and Cortisol Awakening Response test, decide to offer a handful of key organic acids on their panel (incidentally, at no extra charge)? The answers will wow you in this terrific podcast with Dr. Carrie Jones, Medical Director at PA. Turns out, looking at compounds such as homovanillic acid, vanillmadilic acid, 5HIAA, pyroglutamate, 8OH2DG and xanthurenate have LOADS to do with our sex hormones and our HPA axis at many different levels. As usual, Dr. Jones provides fun analogies (how does a trampoline explain perimenopause?), clinically useful information on test interpretation and on intervention considerations. Don’t miss it.

Episode 37: The Gut/Thyroid Connection with Dr. Michael Ruscio

Fri, 16 Mar 2018 10:01:35 -0400
Join me for an interesting, clinician-friendly conversation on the gut/thyroid axis with Dr. Mike Ruscio. Dr. Ruscio challenges both conventional understanding (where the gut/thyroid relationship isn’t recognized outside the research setting) and in the functional medicine world, where he argues we are often over-treating and over-testing thyroid function. What is the thyroid adrenal relationship? What should we expect with regard to thyroid antibodies and successful treatment? What should we be thinking about with regard to gut health when diagnosing and treating thyroid disease? Listen to this great New Frontiers episode where we dive deep into all this and more!

Episode 36: Changing the World with Unconventional Medicine – A Conversation with Chris Kresser

Tue, 20 Feb 2018 12:21:18 -0400
When Chris Kresser, M.S., L.Ac, was in his early twenties, he traveled the world surfing and learning to meditate. Along the way, he fell ill — and when he returned to the States he discovered that the conventional medical paradigm had little to offer when it came to treating complex, chronic illness. So he embarked on his own healing journey, studying acupuncture and Chinese medicine and learning about ancestral health. Today he is a globally recognized leader in the fields of functional and integrative medicine. In this podcast, he talks with Dr. Fitzgerald about being one of the first holistic practitioners to establish a solid online presence; why blogging and writing about functional, ancestral, and integrative approaches to health matter today more than ever; and how the current medical paradigm needs to be reinvented both to prevent and reverse chronic disease and to prevent the collapse of the entire healthcare system. His new book Unconventional Medicine is available now.

Episode 35: SPONSORED: Dr. Kenneth Brown / Atrantil

Tue, 13 Feb 2018 09:47:24 -0400
Small-intestinal bacterial overgrowth, or SIBO, is notoriously hard to treat. Patients often experience persistent bloating—and even when they find relief, symptoms can return months later, seemingly out of the blue. After struggling to help patients feel better using the tools of conventional gastroenterology, Dr. Ken Brown began to research compounds that could effectively treat SIBO-related bloating. The result of his work is Atrantil, the only all-natural formulation for treating SIBO-related bloating. In this podcast, Dr. Fitzgerald talks to Dr. Brown about dosing and treating patients with Atrantil, when to run further tests, and what other treatments can be used in conjunction with Atrantil to get the best results.

Episode 34: Miracle Mind, Warrior Heart: A conversation with JJ Virgin

Wed, 22 Nov 2017 21:12:09 -0400
JJ Virgin was a well-known fitness and nutrition expert and author of several books when her son was hit by a car and severely injured. The doctors told her to prepare for the worst; they didn’t expect him to make it through the night. But, Grant lived. And JJ’s insistence on making sure he had access to both conventional and functional medical care is the reason why. She became an expert on the essential interventions for severe traumatic brain injury and insisted on their use during his recovery. In this podcast, the four-time New York Times bestselling author tells the story of her son’s accident and recovery, talks about her newest book, Miracle Mindset, and shares amazing clinical pearls on treating traumatic brain injury with functional interventions. In this podcast, you’ll hear JJ’s list of essential interventions for severe traumatic brain injury, including CBD oil with omega 3’s Essential oils, lavender combination (find details at www.grantvirgin.com) Autologous stem cell therapy (stem cell revolution) Progesterone/hormone balancing Prayer Diet Very high dose omega-3 fatty acids (up to 20 grams) Amino acids (higher dose branched-chain amino acids to prevent catabolism) Hyperbaric oxygen therapy The power of mindset Avoiding hospital food

Episode 33: SPONSORED: Further Down the Elemental Diet Road with Dr. Corey Schuler

Sat, 18 Nov 2017 10:55:33 -0400
Elemental Diets have a long therapeutic use history for myriad GI issues. EDs allow the gut to take a break from the hard work of digestion, offering the GI tract a chance for renewal and repair. They have been shown to help with a variety of conditions, including SIBO, IBS, non-specific intestinal inflammation, and autoimmunity, including IBD (among others). In this podcast, the director of clinical affairs for Integrative Therapeutics, Dr. Corey Schuler, answers some of the most frequently asked questions about using the Elemental Diet with patients, from how to use it while simultaneously treating other conditions (like fungal overgrowth or severe vitamin D deficiency) to creative ways to help patients stick to a challenging eating protocol.

Episode 32: SPONSORED | The Cortisol Awakening Response With Mark Newman, MS

Wed, 25 Oct 2017 11:54:28 -0400
Mark Newman is the founder Precision Analytical and the developer of the DUTCH test, one of the most accurate and patient-friendly measures of sex hormones on the market. The test eliminates the need for multiple types of testing by using dried urine to measure sex hormones, hormone metabolites, and free cortisol. Free cortisol is a key indicator of the health of the HPA axis — and having that measure, alongside a measure of sex hormones and their metabolites, gives providers more information so they can achieve better clinical outcomes. The test can be especially valuable in complex cases. Now, Mark has developed DUTCH Plus with Cortisol Awakening Response and he talks with Dr. Fitzgerald about the new test, testing best practices, and the most cost effective tests for patients.

Episode 31: Calorie-Restricted Ketogenic Diet for Cancer with Miriam Kalamian CNS

Tue, 17 Oct 2017 17:10:51 -0400
Tumor cells have more insulin receptors than healthy cells, so they preferentially metabolize glucose. When you cut off the glucose supply to tumor cells, they struggle to make the fuel they need to proliferate. The ketogenic diet sharply limits the glucose that reaches tumor cells (while providing other anticancer benefits), and animal studies (and one small but seminal human study) have shown promise in using the ketogenic diet as an adjunctive treatment for cancer. Author of the new book, Keto for Cancer, Miriam Kalamian, EdM, MS, CNS, talks with Dr. Fitzgerald about the how ketogenic eating for cancer differs from other keto and low-carb protocols and outlines specific steps for pacing a keto protocol for the specific needs of cancer patients.

Episode 30: Transformational Approaches to Multiple Sclerosis and Autoimmunity with Dr. Terry Wahls

Fri, 29 Sep 2017 23:49:38 -0400
Dr. Terry Wahls was a practicing primary care physician when she was diagnosed with relapsing-remitting MS. Despite treatment at some of the finest medical institutions in the United States, her health progressively declined until she could no longer walk. When she discovered functional medicine, she made a rapid turnaround. Soon she wasn’t just walking again, she was doing 20-mile bike rides. Today, Dr. Wahls conducts research using variations of her protocol, including intensive directed nutrition, progressive exercise programs, electrical stimulation, and the use of dietary supplements for patients with MS. She conducts her research at the Iowa VA, through the University of Iowa and is supported through grassroots fundraising. In this episode of New Frontiers in Functional Medicine, Dr. Wahls talks with Dr. Fitzgerald about her physical and spiritual transformation — and how other patients with chronic conditions can realize similar results.

Episode 29: The Vaccine Balancing Act with Dr. Hilary Andrews

Wed, 30 Aug 2017 15:51:16 -0400
I went to school with Dr. Hilary Andrews. She graduated before me, but I recall her then—she had a reputation for brilliance (and was voted class valedictorian, incidentally). Hilary applied that brilliance to childhood health and nutrition, which inevitably included investigation around vaccine safety. Flash forward to current time, Hilary continues to research and lecture extensively on the topic of immunization. She’s developed a number of CE courses available for clinicians. Make no mistake: Dr. Andrews recognizes the profound benefits of immunization-from the virtual elimination of polio, to the exciting work in cancer. However, Dr. Andrews also recognizes among other things, that one immunization schedule does not fit all. And that optimizing baby’s health, including supporting immune system maturation, ensuring nutrient sufficiency, and adequate detoxification capacity, is essential to ensure the safest, most effective response.

Episode 28: Moving Beyond SIBO with Dr. Vincent Pedre

Mon, 26 Jun 2017 00:00:00 -0400
Small Intestinal Microbial Overgrowth: A Conversation with Dr. Vincent Pedre, MD IFMCP All microbes, not just bacteria, can contribute to problems in the small intestines. Today more than ever, we see patients with hard-to- treat gut problems. Dr. Pedre brings his own gut healing journey and Functional Medicine background to the table to talk to us about treating patients with SIBO-or as he likes to call it-SIMO, which encompasses microbes beyond bacteria and includes the oft-overlooked fungal piece of the puzzle. Dr. Pedre shares loads of treatment pearls from his gut-centric practice, but reminds us that any protocol must be individualized for the person sitting in front of us.

Episode 27: SPONSORED | Using DUTCH hormone Test with Dr. Carrie Jones

Sun, 28 May 2017 00:00:00 -0400
Dr. Carrie Jones and I went to medical school (National College of Natural Medicine) together. She was a brilliant, awesome friend then, and still is. What a privilege it’s been to watch her grow into the expert she is today. As you’ll see in her bio, Dr. Jones has been focused on women’s health and hormones her entire career which has spanned academia, clinical practice and now as the chief medical officer at Precision Analytical, home of the DUTCH dried urine hormone panel. Given Carrie’s background, she’s uniquely suited to train us on using the DUTCH panel, as she’s literally interpreted thousands of these tests over the years. Her podcast is chock full of Monday morning pearls of the best kind- actionable content I think you’ll appreciate and use immediately.

Episode 26: SPONSORED Practical Application: Using An Elemental Diet in Clinical Practice

Dr. Corey Schuler is a man of many talents- an educator as well as a practitioner in integrative and functional medicine. In today’s podcast, Dr. Schuler will be wearing his nutritionist hat as we discuss individually designed elemental diets. Some of the applications we cover will be well-known to practitioners and patients alike. Others don’t have precedent in clinical practice but listen to this expert as he walks you through the critical thinking he calls on to come up with new and novel ways to use elemental diets to heal a number of conditions.

Episode 25: Stem cell therapy: Is it ready for Prime Time FxMed?

Wed, 03 May 2017 16:01:04 -0400
As you probably know, stem cell therapy outside of the research setting is the Wild West. It’s offered everywhere, here and outside of the US (there’s a whole “stem cell tourism trade”). Radical claims are made routinely without much evidence or oversight. Pricing for therapy, and protocols used, vary widely, although anyone (even those participating in research trials) can expect to spend thousands of dollars. Given that my patient has MS, I reached out to Dr. Terry Wahls and asked if she had any insight into a direction for us. She suggested I look into a massive, years-long multi-center clinical trial using stromal vascular fractions (AKA adipose-derived stem cells and growth factors) for a variety of conditions, including MS. The first publication from this study out February 2017, focusing on safety of SVF over 5 years, demonstrated a very low number of adverse events, and significant improvement in pain rating in a variety of musculoskeletal diseases.

Episode 24: The KBMO FIT: A Novel and Reliable IgG Food Sensitivity Test.

Mon, 17 Apr 2017 17:39:17 -0400
In general, I am a fan of IgG food sensitivity testing. While we can in some cases manage just fine using a standard elimination and challenge protocol, IgG testing can benefit patients in a few ways, such as: providing motivating data, individualizing the foods needing to be removed and identify less-common antigenic foods. However, if you are using IgG food sensitivity testing in practice, you’ve no doubt encountered false negatives and positives. (Indeed, you may have abandoned IgG testing for these reasons!) Dr. Brent Dorval, through a rather remarkable epiphany during his post-doctorate work, formed the hypothesis that testing for IgG/food immune complexes, along with the specific complement protein (C3d) that induces the inflammatory response, would increase the reliability of the test considerably. After a number of years of bench and clinical research, Brent finalized the methodology for his assay (now called the FIT Test, offered through KBMO Diagnostics) and the rest is history. Tune into our podcast for an overview on IgG food sensitivity testing (great if you are new to using this laboratory test, or an individual interested in this testing), and specific details about the unique FIT test, including case studies. See the links below for all the info on the FIT Test, including his current publication. Stay tuned for more research in the pipeline!

Episode 23: Functional Strategies for the Management of Gastrointestinal Disorders

Tue, 21 Mar 2017 22:34:07 -0400
Functional hypochlorhydria is a condition we see so often, yet Prilosec is a top ten medication: what’s the disconnect? Probiotics: which ones, how much, combo or single strain? What does the research really show probiotics are actually doing? Is there any truth to probiotics colonizing the GI tract? And what about soil-based probiotics, any reason to be jumping on that bandwagon? What is the correct lab test for identifying pancreatic exocrine insufficiency (PEI), and what is the optimal range? Is there any utility to testing fecal fats? What enzymes (vegetarian or animal-based), botanicals and other interventions are appropriate for addressing PEI?

Episode 22: Gene Whispering with Dr. Moshe Szyf

Mon, 27 Feb 2017 15:04:20 -0400
Have you been wondering what you should really do with the 23andme genetic data that you’ve gathered? Wondering if you should even take the test at all? Or wondering what the future of genetic/epigenetic medicine is? This podcast is for you. I am especially excited to bring you this conversation with epigenetic legend, Dr. Moshe Szyf. The study of epigenetics is continually breaking new ground in understanding how our environment dramatically influences our gene expression. With myriad published research studies and his ongoing work, Dr. Szyf is at the forefront in shaping this evolution. The power of epigenetics to alter the course of our health is compelling, and I hope you will enjoy the discussion we had, which I hope will be one of many.

Episode 21: Arthritis - oxidative stress, microbes, gut permeability and more with Dr. Susan Blum

Wed, 15 Feb 2017 22:56:52 -0400
Thanks to Dr. Susan Blum, functional medicine has even more to offer for patients with rheumatoid arthritis (RA) and osteoarthritis (OA). She shares new insights about RA’s underlying causes, details what goes missed in treatment plans, and gives practical tips for mining data from stool tests, utilizing functional blood markers, and combining herbs and probiotics to reverse processes that other practitioners may think are permanent

Episode 20: A Deeper Understanding of Fibromyalgia and Clinical Approaches

Wed, 28 Dec 2016 14:31:05 -0400
Fibromyalgia can be a particularly difficult condition to address conventionally, but Functional Medicine really has a lot to offer here. In this podcast, we mine the wealth of information that Dr. David Brady brings to the table on this important topic, including: · The signs and symptoms of fibromyalgia and how it is diagnosed (previously-defined tender points are no longer used!) – see also Dr. Brady’s questionnaire at www.fibrofix.com · What other mimicking conditions need to be considered or ruled out · How fibromyalgia differs from chronic fatigue syndrome—vastly different disorders that are commonly confused · Why not all pain is driven by inflammation · How not to fall into the trap of only looking at mitochondrial dysfunction · Organic acids, catecholamines, food reactivity and other relevant labs for assessment and tracking · Childhood and adult stress patterns in (especially female-dominated) fibromyalgia, and how that factors into interventions · Additional intervention options such as sleep support, energy pathways, detox, exercise, diet, immune balancing to reset metabolic patterns and promote recovery

Episode 19: Functional Gynecology Practice Pearls with Dr. Anna Cabeca

Mon, 14 Nov 2016 16:49:16 -0400
Dr. Cabeca is a wealth of information and inspiration when it comes to women’s health. I am delighted to share my conversation with her this month, in which you’ll learn about: - How Dr. Cabeca transitioned from performing multiple surgeries per week, to only needing to recommend a handful per year with a functional medicine approach - The best lab tests and specimens for hormone assessment - The importance of liquid chromatography mass spectrometry for serum free testosterone measures - Factors to be aware of that can confound hormone testing results - Estrogen metabolites and the importance of methylation assessment - The sweet spot of keto-alkaline status for sex hormone balance, cortisol management, mental clarity, insulin sensitivity and weight loss (target pH of 7, and some ketones 3+ days per week) - The benefits of vaginal testosterone and DHEA for tissue repair and incontinence - Watching out for behavior change with testosterone to ensure appropriate dosing and saving marriages! - Addressing vaginal dryness with safe oils and DHEA, diet and lifestyle

This is a jam-packed discussion on cancer prevention and management, from the soul-searching demands of a cancer diagnosis to highly practical treatment approaches.

Episode 16: Cancer as a Mitochondrial Metabolic Disease & The Calorie-Restricted Ketogenic Diet

Mon, 01 Aug 2016 23:23:47 -0400
Dr. Seyfried has dedicated his career to changing the way we think about- and therefore treat- cancer. Going back to Otto Warburg and others, couple with newer research Tom and his colleagues are actively conducting, it’s clear that the origin of cancer is in a fundamental disruption of mitochondrial oxidative phosphorylation. Cancer is not, as is commonly thought, a genetic disease. While somatic genetic mutations abound, their origin is from a proliferation of reactive oxygen species generated by damaged mitochondrial cellular respiration. The triggering agents for cancer are anything that disrupts mitochondrial energy metabolism, from chemicals and xrays, to viruses, diet (including GMOs) and lifestyle habits. Switching primary fuel sources from glucose to ketones by using the calorie-restricted ketogenic diet (RKD), we start to shut down the energy supply to cancer cells and reverse the trajectory of the disease.

Episode 14: Taking a Deeper Dive into Eat Fat, Get Thin with Dr. Mark Hyman

Tue, 31 May 2016 15:19:42 -0400
Science has demonstrated for over a century that fat simply isn’t the macronutrient villain it’s been made out to be. Join me and Dr. Mark Hyman as we spend some time discussing his new NYT best-selling book Eat Fat, Get Thin. We drill down into the research that has been published over the years demonstrating the largely beneficial aspects of most fatty acids.

Episode 13: Functional Dentistry and the Oral-Systemic Connection with Dr. Mark Burhenne, DDS

Mon, 11 Apr 2016 00:00:00 -0400
The oral-systemic disease connection has long been established (recall older recommendations for prophylactic antibiotics before dental work in individuals with endocarditis or joint implants), but with the emerging data on the oral microbiome, new attention is being paid to oral health and the prevention of diseases ranging from cardiovascular to autoimmune and more. A transient bacteremia is the normal course after brushing, but when there is a breakdown in oral health and alterations to the oral microbiome, this transient bacteremia leads to chronic, systemic inflammation, contributing to the course of systemic disease. There is much we can do to support our patients in correcting this inflammation, not the least of which includes a healthy, sugar-free diet; regular cleanings and appropriate brushing techniques. Ideally, the dentist is a part of the functional medicine team. Disordered sleep breathing is a wide-spread, underappreciated problem in children and adults. Once thought to be primarily stress or trauma related, bruxism is now understood to be evidence of disordered breathing (see reference link below). Additionally, a scalloped or fissured tongue (macroglossia) also contribute to disordered sleep breathing.

Episode 11: DUTCH: A Novel (and useful!) Urinary Hormone Test with Mark Newman

Tue, 09 Feb 2016 00:00:00 -0400
As a clinician measuring urine, serum and salivary hormone levels in my patients routinely, I’ve always got questions around which testing method is the best. Thus, I was excited to chat with Mark Newman and pick his brain on all things hormone testing. As he says, “I’m an inch wide and a mile deep. I’ve spent pretty much my whole career in measuring reproductive and adrenal hormones.” It’s true. As you’ll hear, Mark is a font of knowledge in this arena. In this interview, Mark covers the various specimen type and their respective utility and limitations, we then dive into a discussion around the unique characteristics of the DUTCH test….In brief, DUTCH is an easy 4 specimen urine test, collected over the course of a day, covering the bases of sex and adrenal hormones, plus metabolites (including 2-Methoxyestrone) and melatonin. It’s reflective of 24-hour output, but diurnal variation is captured as well-- thus great for cortisol.

Episode 10: The History (& Future) of Functional Medicine: with IFM Co-Founder, Dr. Jeff Bland

Sun, 17 Jan 2016 00:00:00 -0400
JEFFREY S. BLAND, PhD, FACN, CNS, is an internationally recognized leader in the nutritional medicine field.

Episode 9: The Functional Medicine Health Coach with Dr. Sandra Scheinbaum

Sun, 20 Dec 2015 00:00:00 -0400
Imagine: You’re a busy FxMed clinician, working overtime treating, educating and supporting your patients as they transition to a new state of health. It’s exciting, and you’re inspired to be practicing medicine in a way you never thought possible. But (to put it mildly) you’re struggling with time management: FxMed is a lot of work! And then into your life comes an individual just as passionate as you are about functional medicine, who happens to be a trained, certified Functional Medicine Coach! They’ve learned the “ins and outs” of Positive Psychology, so they understand the change process and can guide your patients supportively and effectively. They’re also familiar with the Functional Medicine model, having been taught by many IFM faculty, so they can assist you with educating and “translating” the FxMed processes. Would this individual be a Godsend to your practice? YES! Learn about functional medicine’s newest team member in this podcast with the Founder and CEO of the Functional Medicine Coaching Academy, Dr. Sandy Scheinbaum. This podcast is perfect for clinicians, folks interested in a FxMed Coaching career, and anyone interested in the process of FxMed.

Episode 8: Functional Psychiatry with Bob Hedaya, MD

Sat, 12 Dec 2015 00:00:00 -0400
According to Dr. Bob Hedaya, it’s malpractice NOT to use functional medicine when practicing psychiatry. ALL of the nodes on the Functional Medicine Matrix [gastrointestinal, endocrine, immune, toxicity, nutritional status and especially psychological, social and spiritual] influence mental health, mental function and brain function. The bottom line is, a good functional approach yields better health, less medicine. In this case-focused inspiring podcast, hear about Dr. Hedaya’s years of clinical experience in using functional medicine to address tough psychiatric conditions.

Episode 7: From Cell to Soul with Dr. Sara Gottfried

Sat, 14 Nov 2015 00:00:00 -0400
From Cell to Soul: A Functional Approach to Women’s Hormone Management with Sara Gottfried, MD. Dr. Sara Gottfried has elegantly distilled her years of clinical experience and thousands of patient contacts into a user-friendly body of knowledge for physician and layperson alike. She’s truly a functional/systems medicine pioneer, combining the best of scientific data with the art (and heart) of medicine. An expert in the area of women's hormones, Dr. Gottfried candidly shares her own personal experience with hormone imbalances. Sara was pivotal on my own journey toward better self-care, as you’ll hear in this podcast.

Episode 6: Enacting an Elimination Diet: Tips for Patients, Clinicians with Jennifer Fugo

Tue, 13 Oct 2015 00:00:00 -0400
One of the cornerstone tools of functional medicine is the elimination diet, be it a straightforward gluten/dairy free plan, or an involved, customized removal of many different foods. On top of this, we want our patients to choose clean, organic sources of foods. This dietary prescription is a tall order for many of our patients. Many years ago, Jen Fugo (author of The Savvy Gluten-Free Shopper: How to Eat Healthy Without Breaking the Bank) was prescribed just such a diet. With very limited funds, she figured out how to navigate the myriad pitfalls and change her life. Today, she’s dedicated her career to assisting individuals on therapeutic diets make the transition healthfully, affordably and successfully.

Episode 5: Osteoporosis- Metabolic Disease of the Bone with Dr. Keith McCormick

Sun, 06 Sep 2015 00:00:00 -0400
As a former Olympian and current Iron Man triathlete, (he qualified for the world championship in Hawaii this year!) Dr. Keith McCormick was diagnosed with severe osteoporosis at 45 years old. His own healing journey lead him to become a world expert on treating osteoporosis from a functional and integrative perspective. His 2008 book, The Whole Body Approach to Treating Osteoporosis, is useful for patient and clinician alike. This podcast is a goldmine of pearls for clinicians treating individuals with bone loss. Topics covered include underlying pathogenic mechanisms, laboratory evaluations and treatments-pharmaceutical and natural. Health savvy patients will find Dr. McCormick’s content useful.

Episode 4: Natural Cures for Dummies - with Dr. Kara Fitzgerald and Dr. Banks

Wed, 12 Aug 2015 00:00:00 -0400
Just released April, 2015, Natural Cures for Dummies is a superb survey of all things Natural Medicine. In this podcast, Dr. Banks and I cover a ton of content: The book, appropriate diets, including the elimination diet and the perils of gluten, we cover his approach to detox, appropriate supplements, genomics and systems medicine, Functional Medicine and so much more.

Episode 3: The Oral Microbiome - with Dr. Kara Fitzgerald and Cass Nelson-Dooley, MS

Mon, 06 Jul 2015 00:00:00 -0400
The oral microbiome is an important part of the gut microbiome and tending to its balance should a routine part of any good “gut protocol.” Indeed, dysbiosis of the oral microbiome (and a leaky oral mucosa) might be key underlying imbalances in pathogenesis of systemic diseases, including autoimmune (IBD, rheumatoid arthritis, Sjogren) as well as cardiovascular disease. As clinicians, addressing our patient’s oral health may be the missing link in treating many systemic diseases. This podcast is great for clinicians as well as anyone interested in gut health, the oral microbiome, autoimmunity, leaky gut and cardiovascular disease.

Episode 2: Air Pollution with Dr. Kara Fitzgerald and Winston Cardwell

Tue, 23 Jun 2015 00:00:00 -0400
Dr. Winston Cardwell’s podcast: best home mold testing, laboratory testing for toxin exposures, best air filtration systems, home cleaning products, “green” building materials, “green” flooring sources and much more!

Episode 1: Chronic Pelvic Pain with Dr. Kara Fitzgerald and Jessica Drummond

Fri, 15 May 2015 00:00:00 -0400
Chronic pelvic pain (CPP), including interstitial cystitis, chronic UTI, myofascial pain, pelvic floor pain, dyspareunia is a common, underappreciated problem in women. Indeed, one study looking at primary care practices found pelvic pain an issue in almost 40% of all reproductive-aged women. CPP is also identified in men, most commonly caused by prostadynia or prostatitis. What can we do as functional medicine clinicians to assist this population? Turns out, quite a bit. Listen to this very interesting and inspiring conversation I had with Jessica Drummond, MPT, CCN, CHC, founder and CEO of the Integrative Pelvic Health Institute. Jessica has made it her mission to train clinicians and treat women using a functional approach to chronic pelvic pain. As a physical therapist who later trained in nutrition (and is currently working on her PhD), Jessica discusses the multifactorial influences on CPP including: gut/microbiome health, hormone imbalances, nutrient deficiencies, stealth infections, diet, mind/body and toxins and what to do about them for our patients.
