117. Dr. Steven Gundry: The Microbiome War Shaping Your Mind
Most people think about the gut as a digestive system, yet emerging research shows it functions more like a command center shaping immunity, metabolism, mood, and even coronary artery calcification. The surprising twist is that your gut may be influencing your brain more than your brain influences your gut. In this episode of Extend, we sit down with Dr. Steven Gundry, cardiac surgeon and world leading expert on the microbiome, to uncover how gut bacteria communicate with your mitochondria and brain, why leaky gut silently drives inflammation throughout the entire body, and how keystone species like Akkermansia help rebuild the gut barrier. We break down the role of vitamin D in activating gut stem cells, the impact of glyphosate on serotonin producing bacteria, and why pasteurized or even dead bacteria can modulate the ecosystem just as powerfully as live strains. We also explore how gut derived signals from short chain fatty acids, gasotransmitters, and microbial messenger RNA shape mood, cognition, vascular health, and long term aging trajectories. Dr. Steven Gundry is a renowned heart surgeon, bestselling author, and pioneering researcher in microbiome science whose work has transformed our understanding of gut driven inflammation, autoimmune disease, and the gut brain axis. What's Discussed: (04:10) Why the gut acts as the body's first brain (07:45) How good and bad microbes compete for control of your cravings and mood (12:30) Why Akkermansia and other keystone species determine gut wall integrity (16:55) How dead and pasteurized bacteria still shape the microbiome (21:20) The link between leaky gut, coronary calcification, and systemic inflammation (27:40) How vitamin D activates gut stem cells to repair the intestinal barrier (32:15) How microbial gasotransmitters, short chain fatty acids, and mRNA communicate with the brain (38:50) Why glyphosate disrupts serotonin producing bacteria and impacts mental health Thank You for Our Sponsors: IM8: Try IM8 today with a 30-day money back guarantee.

116. Dr. Stephanie Venn-Watson: The New Essential Fatty Acid
Most people hear "saturated fat" and think of something harmful, yet emerging research reveals that one specific fatty acid supports stronger cell membranes, healthier metabolic function, and better long-term resilience. C15 plays a unique role in the biology of aging and may help explain why certain populations experience longer, healthier lives. In this episode of Extend, we sit down with Dr. Stephanie Venn-Watson, veterinary epidemiologist and co-founder of Fatty15, to uncover how Navy dolphin research led to the discovery of C15 as the first essential fatty acid identified in nearly a century. We unpack why odd chain fats behave differently than traditional dietary fats, how C15 stabilizes cellular aging pathways, and why declining levels in the modern diet may be contributing to metabolic and cognitive decline. We also explore how C15's effects on ferroptosis, inflammation, liver markers, and mitochondrial efficiency offer a new way to support healthspan at the cellular level. Dr. Stephanie Venn-Watson is a leading veterinary epidemiologist whose groundbreaking research on marine mammals revealed the essential role of C15 in aging, metabolism, and cellular integrity, ultimately leading to the development of the concentrated and clinically studied Fatty15 formulation. What's Discussed: (07:20) How Navy dolphin research led to the discovery of C15 (11:45) Why C15 functions differently from traditional saturated fats (15:10) The link between C15, cell membrane stability, and aging (19:40) How declining C15 levels influence metabolic and inflammatory markers (24:00) The science of ferroptosis and why it accelerates aging (28:30) How C15 interacts with AMPK, PPAR, mTOR, and mitochondrial pathways (33:10) The challenge of getting enough C15 through modern diets (38:25) How Fatty15 provides a bioavailable source of this essential fatty acid Thank You for Our Sponsors: Nexthealth: NextHealth: Your destination for cutting-edge health optimization—from IV therapy to hormone balancing.

115. Dr. Shivani Gupta: Heal Inflammation Through Ayurvedic Science
Most of us think inflammation is something we can fix with supplements, lab tests, or the latest diet trend. But what if the real solution comes from ancient wisdom that modern science is finally catching up to? In this episode of Extend, we sit down with Dr. Shivani Gupta, Ayurvedic practitioner, author, and founder of Fusionary Formulas, to explore how Ayurveda bridges timeless principles with modern longevity science. We break down how your dosha or "elemental design" shapes digestion, energy, and stress, and why aligning your daily rhythm with your biology can lower inflammation and optimize performance. We also explore the science behind Ayurvedic rituals that calm inflammation from the inside out, from cooking with healing spices like turmeric and ginger to grounding, tongue scraping, and creating simple routines that support recovery and resilience. Dr. Shivani Gupta is an Ayurvedic expert and founder of Fusionary Formulas, a modern supplement line combining ancient herbal medicine with clinical research. Her upcoming book, The Inflammation Code, reveals how to decode inflammation through food, lifestyle, and ritual to live longer and stronger.

114. Julia Putzeys: The App That Decodes Your Food Lies
Most of us grew up thinking anything sold at the grocery store was safe to eat. But behind every "heart healthy," "high protein," or "low fat" label lies a different truth one built on ultra-processed ingredients, chemical additives, and marketing tricks. In this episode of Extend, we sit down with Julia Putzeys, founder of the Trash Panda App, to uncover what's really in our food and how to make smarter choices that protect our long-term health. We break down what defines an ultra-processed food, why seed oils, food dyes, and artificial sweeteners disrupt metabolism and gut health, and how ingredient literacy can literally change your biology. We also explore how small, consistent choices like swapping one product at a time can help you shift from calorie counting to nutrient density and teach your kids the same. Julia Putzeys is a software developer turned nutritionist and creator of Trash Panda, the viral app helping millions of people decode food labels, identify hidden additives, and choose real, whole ingredients. What's Discussed: (09:00) How Ultra-Processed Foods Impact Longevity and Chronic Disease (12:30) The Psychology and Science Behind Food Addiction (20:00) Why "Low-Fat" and "Sugar-Free" Often Mean More Toxic (29:50) The Real Problem With Seed Oils and Food Dyes (18:00) How to Retrain Your Taste Buds and Microbiome (32:00) Practical Swaps for Clean, Nutrient-Dense Eating Thank You for Our Sponsors: Timeline: 20% off your order.
