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