The Ty Beal Show

What does the science say about plant-based diets, longevity, and cardiovascular health? In this episode of The Ty Beal Show, Dr. Gil Carvalho, research scientist and host of Nutrition Made Simple with over a million monthly viewers, cuts through the noise to reveal what the evidence shows. Dr. Carvalho challenges common assumptions about plant-based eating, explaining why the term itself is misleading and how Mediterranean, pescatarian, and even well-planned omnivorous diets can be equally health-promoting. Drawing from Harvard's landmark healthy aging studies and genetic research, he reveals how optimized nutrition patterns can add 10-12 years to your lifespan—but warns against the dangerous mythology surrounding certain dietary extremes. This deep-dive conversation explores the mechanics of cardiovascular disease, with Dr. Carvalho breaking down why ApoB—not LDL cholesterol—is the gold standard for assessing heart disease risk. He shares his personal experience with genetic risk factors including elevated Lp(a), explaining when imaging tests like coronary calcium scores become valuable and how to optimize lipid levels through diet, lifestyle, and targeted medications. What you'll learn: Why "plant-based" encompasses everything from Mediterranean to vegan diets—and why the distinction may matter less than you think The critical difference between ApoB and LDL cholesterol for predicting heart attacks Why B12 deficiency on vegan diets can cause irreversible nervous system damage How isometric exercises like wall squats can lower blood pressure as effectively as medication Why weight loss consistently improves glucose metabolism regardless of diet type Dr. Carvalho also shares his personal experiments with statin medications, revealing how different drugs affected his insulin resistance and ApoB levels differently, and explains why promising new Lp(a)-lowering medications might revolutionize cardiovascular prevention within the next few years. Whether you're navigating conflicting dietary advice, concerned about cardiovascular risk, or simply want to understand what nutritional science says about plant-based diets, this episode provides evidence-based clarity from one of the field's most trusted science communicators.

Can what you eat actually treat depression? In this episode of The Ty Beal Show, Dr. Ally Jaffee, MD, a psychiatry resident doctor and co-founder of NutriTank, reveals the science behind nutritional psychiatry and why your gut health might be the key to mental wellness. Dr. Jaffee, winner of the 2024 Cura Mental Health Advocate of the Year Award, shares her deeply personal journey into psychiatry—from losing her grandfather to suicide at two weeks old to experiencing her own clinical depression during medical school. Her story illuminates the concept of the "wounded healer" in healthcare and how lived experience can enhance, rather than compromise, clinical practice. Drawing from landmark research including the SMILES trial—the first randomized controlled trial to show dietary intervention could put depression into remission—Dr. Jaffee explains how the gut-brain axis creates a bidirectional pathway between our digestive system and mental health. She breaks down why people with inflammatory bowel disease have higher rates of mental illness, and how restoring gut microbiome balance can enhance both mood and medication effectiveness. What you'll learn: Why medical schools barely teach nutrition despite diet being the leading cause of death worldwide The "triple F" approach to brain health: fermented foods, fiber, and fish How NutriTank is revolutionizing medical education across the UK and influencing national health policy Why traditional psychiatric treatment often jumps straight to medication instead of addressing root causes The power of "safe disclosure"—when healthcare providers thoughtfully share their own experiences How social prescription is transforming mental health treatment for young people Why closing "third spaces" like youth centers contributes to rising adolescent loneliness The remarkable story of transforming psychiatric ward culture through cooking programs Dr. Jaffee also addresses the mental health crisis among young people, explaining how creative arts, nature therapy, and non-traditional interventions can succeed where conventional talk therapy fails. From spoken word poetry to surf therapy, she reveals innovative approaches that are helping disconnected youth find community and healing. Whether you're struggling with mental health challenges, curious about the food-mood connection, or interested in how healthcare systems can evolve beyond the "pill for every ill" mentality, this episode offers hope and practical insights from a passionate advocate working to transform both medical education and patient care.

Why do so many conventional treatments fail to solve chronic health problems? In this episode of The Ty Beal Show, Chris Kresser, MS, LAc, former functional medicine practitioner and New York Times bestselling author, reveals how a systems-based approach uncovers and addresses the true drivers of disease—leading to lasting results instead of temporary symptom relief. Drawing on over 15 years of clinical practice, Chris explains the critical differences between functional, integrative, and conventional medicine, sharing remarkable stories of patients who reversed serious autoimmune conditions, avoided major surgery, and reclaimed their health. He breaks down how environmental triggers, gut health, nutrient deficiencies, and lifestyle factors interact to cause chronic illness—and how personalized nutrition and lab testing can uncover the hidden causes conventional ranges often miss. What you'll learn: Why functional medicine asks "why" instead of just suppressing symptoms with drugs or supplements How a patient with severe Crohn's disease avoided intestinal surgery and healed in weeks Why conventional lab ranges often overlook early nutrient deficiencies The most common nutrient shortfalls: potassium, magnesium, vitamin D, EPA/DHA, iron, zinc, and B12 Why there's no one-size-fits-all diet—and how to create a personalized nutrition template The 80/20 principle: why striving for perfection can harm your health How social connection and stress management can be as important as diet for healing Chris also shares his surprising take on vegan, carnivore, and omnivorous diets, explains how lab work can reveal dietary patterns, and tells the story of the "beer and pizza" recovery that transformed a patient's life. Whether you're facing unexplained symptoms, frustrated by conventional treatments, or simply curious about holistic approaches, this episode offers a masterclass in root cause medicine from one of the field's most experienced voices.
