    Food Fix Uncensored: The Chronic Disease Crisis & How We Fix It | Mark Hyman, MD

    In this episode, Dr. Mark Hyman joins me to unpack his new book Food Fix Uncensored and the revolution in American food policy—chronic disease, ultra‑processed food, SNAP reform, new dietary guidelines, and more. With over three decades of experience in functional medicine and a track record of advising policymakers at the highest levels, Dr. Hyman offers an insider's perspective on what he calls "the most exciting moment" in his career—a time when the ideas he once thought would take generations to implement are suddenly becoming reality. We explore why chronic diseases that barely existed 150 years ago now affect nine in ten Americans, how ultra-processed foods bypass our biology's natural satiety mechanisms, and the powerful story of a South Carolina family on food stamps who transformed their health by simply learning to cook real food.   We also dig into the unprecedented policy changes reshaping the American food landscape—from SNAP waivers allowing states to restrict soda purchases to the new dietary guidelines that for the first time call out highly processed foods. The conversation turns to implementation: mandating nutrition education in medical schools, reforming agricultural policy, changing food marketing to children, and funding $100 million in functional medicine research through Medicare. Whether you're a healthcare professional, policymaker, or someone trying to navigate the modern food environment, this episode offers a candid roadmap for the revolution that's already underway—and how you can be part of it.

    Ultra-Processed Foods, Sugar & What the Evidence Shows | Michael Goran, PhD

    In this episode, Dr. Michael Goran—one of the leading scientists behind the 2025 Dietary Guidelines for Americans—joins the show to reveal what the evidence says about highly processed foods, refined grains, and added sugars. As the researcher who led three critical umbrella reviews that shaped these landmark guidelines, Dr. Goran walks us through the methodology behind the recommendations and shares findings that may surprise you: a 10% reduction in highly processed food intake can lower diabetes risk by 14%, replacing just one serving of refined grains with whole grains reduces mortality risk by 13%, and cutting one sugary beverage per day can slash diabetes risk by 26%. We also explore a paradigm shift in nutrition science—the idea that the burden of proof should now fall on highly processed foods to demonstrate safety, rather than requiring whole foods to prove their benefit. The conversation gets practical when we dig into what these findings mean for families. Dr. Goran challenges some of the guidelines' recommendations (like avoiding all added sugars until age 10) while strongly endorsing others—particularly the emphasis on eliminating liquid sweetness from children's diets, including fruit juices, sports drinks, and even diet sodas, which show concerning links to all-cause mortality. We discuss "kitchen processing" as an alternative to factory-processed foods, the importance of developing basic cooking skills, and why the first few days of dietary change are the hardest but also the most rewarding. If you want to understand what the new dietary guidelines mean for your health and your family, this conversation offers both the science and the practical wisdom to make meaningful changes.

    The Politics of Food Guidelines and the Real Food Revolution | Marion Nestle, PhD

    In this episode, legendary food policy expert Dr. Marion Nestle joins the show to discuss her new book "What to Eat Now" and share her unfiltered take on the 2025 Dietary Guidelines for Americans. At 89 years old, Dr. Nestle brings over five decades of experience to the conversation, including her role as editor of the 1988 Surgeon General's Report on Nutrition and Health and as a member of the 1995 Dietary Guidelines Advisory Committee. We explore how supermarkets are designed to maximize spending rather than health, why the food industry's profit motive conflicts with consumer wellbeing, and why the simplest nutrition advice—eat real food, not too much, mostly plants—remains so difficult to follow.   We also dig into the controversy surrounding the new dietary guidelines, examining both what Dr. Nestle praises (the emphasis on real food and limiting ultra-processed products) and what concerns her (the meat-forward messaging and questions about equity). As a member of the Scientific Review Group that developed the scientific foundations for these guidelines, I offer an insider perspective on what the evidence actually says versus how it's been communicated. The conversation turns to implementation challenges—from school meals to SNAP policy—and asks the critical question: how do we translate good dietary guidance into meaningful change when funding for community programs is being cut? If you're interested in understanding the forces shaping American food policy and what it means for public health, this episode offers a candid, nuanced discussion from two experts coming from different perspectives on the debate.   Timestamps 00:00 Introduction to Marion Nestle's Journey 04:20 The Evolution of Food Choices 10:36 Understanding Nutrition and Consumer Choices 13:17 The Role of Dietary Guidelines 19:23 Insights on the New Dietary Guidelines 28:08 The Whole Milk Debate 30:59 Philosophy of Eating Real Foods 32:19 Equity in Dietary Guidelines 33:49 Policy Changes and School Meals 35:43 Plant-Based vs. Animal Protein 39:37 Messaging and Public Perception 41:22 Conflicts of Interest in Guidelines 44:43 Evidence and Scientific Review 47:36 Implementation Challenges in Schools 52:41 Future of Dietary Guidelines   Connect with Ty YouTube: https://www.youtube.com/@TyBealPhD X: https://www.x.com/TyBealPhD LinkedIn: https://www.linkedin.com/in/tybeal Instagram: https://www.instagram.com/tybealphd Website: https://www.tybeal.com

    Evolutionary Psychiatry & Brain Health | Emily Deans, MD

    In this episode, board-certified psychiatrist and "Evolutionary Psychiatry" creator Dr. Emily Deans joins the show to explore the profound connection between what we eat and how we think and feel. We discuss the limitations of a purely pharmaceutical approach to mental health and examine how an evolutionary framework—looking at the mismatch between our hunter-gatherer biology and our modern industrial environment—can offer a more complete picture of brain health. Dr. Deans breaks down the science behind the gut-brain axis, explaining how the microbiome, vagus nerve, and hormonal signals constantly communicate between our digestive system and our brain to influence mood and cognition. We also dive into the nuances of nutritional psychiatry, moving beyond "single nutrient" studies to look at whole-diet interventions like the modified Mediterranean diet. The conversation challenges common dietary dogmas, highlighting the critical role of brain-essential nutrients often missing from plant-exclusive diets—such as creatine, B12, and iron—and why red meat may actually support mental well-being despite its controversial reputation. From the dangers of "savory frosting" (ultra-processed foods) to the link between metabolic syndrome and depression, this episode offers practical, evidence-based insights for anyone looking to support their mental health through diet. Timestamps 00:00 Introduction 02:05 Limitations of psychiatric medications 03:00 Evolutionary mismatch & modern life 05:51 Paleo diet vs. standard advice 08:11 How diet affects mood & cognition 12:21 The gut-brain axis: Vagus nerve & microbiome 15:54 Single nutrients vs. whole diets 18:24 The SMILES trial & Modified Mediterranean Diet 20:00 Diet and hippocampus size 22:39 Red meat and creatine 23:32 Nutrients in vegan vs. omnivore diets 25:09 Understanding inflammation 28:41 Ultra-processed foods ("Savory Frosting") 29:34 Metabolic syndrome & depression 32:34 Brain metabolism & mitochondria Dr. Emily Deans X: https://x.com/evolutionarypsy Psychology Today: https://www.psychologytoday.com/us/contributors/emily-deans-md Private Practice: https://www.emilydeansmd.com Connect with Ty Website: https://www.tybeal.com X: https://www.x.com/TyBealPhD LinkedIn: https://www.linkedin.com/in/tybeal Instagram: https://www.instagram.com/tybealphd

    Unpacking the New Dietary Guidelines: Real Food, Protein, and the Fat Debate | Mario Kratz, PhD

    In this special episode, I share a conversation hosted by Dr. Mario Kratz, former professor at the Fred Hutch Cancer Center and founder of Nourished by Science, to unpack the recently released Dietary Guidelines for Americans. We discuss the focus on "real food" that prioritizes minimally processed nutrient-dense options, examining the move to center diets around quality protein sources and fiber-rich plants while tackling the chronic disease crisis linked to diet and lifestyle. We examine the bold recommendations to significantly increase protein intake and the transformative language used to discourage refined grains and highly processed foods. The conversation also critiques the guidelines' stance on dietary fats, highlighting the controversy over saturated fats and the omission of seed oils, while exploring the nuances of full-fat dairy, the "food matrix" effect, and the practical challenges of implementing these changes in public policy. Timestamps 00:00 Introduction to Dietary Guidelines Discussion 01:08 Overview of Current Health Issues 03:25 Critique of Previous Dietary Guidelines 06:30 The New Food Pyramid Explained 09:55 Protein and Fiber: The New Focus 16:15 Specific Dietary Recommendations 25:20 The Role of Dairy in Nutrition 30:03 Fruits and Vegetables: A Daily Essential 32:30 Understanding Dietary Fats and Their Impact 45:27 The Role of Whole Grains in Nutrition 51:34 Limiting Processed Foods for Better Health 58:21 Alcohol Consumption and Health Guidelines Dr. Mario Kratz Website: https://nourishedbyscience.com YouTube: https://www.youtube.com/@nourishedbyscience Connect with Ty X: https://www.x.com/TyBealPhD LinkedIn: https://www.linkedin.com/in/tybeal Instagram: https://www.instagram.com/tybealphd Newsletter: https://www.tybeal.com

    Livestock, Climate, and the Myth of “Natural” Emissions | Pablo Manzano, PhD

    In this episode, rangeland ecologist Dr. Pablo Manzano of the Basque Centre for Climate Change joins the show to challenge the dominant narrative that livestock are inherently harmful to the climate and the planet. We examine the two most common critiques of animal agriculture—greenhouse gas emissions and land use—and unpack why these arguments often ignore how ecosystems actually function. Dr. Manzano introduces the concept of baseline emissions, explaining how grazing livestock largely replace the ecological role once filled by vast populations of wild herbivores, meaning many methane emissions attributed to livestock are part of natural, unavoidable ecosystem processes rather than purely human-caused additions. We also explore why land use itself is not inherently negative, how undergrazing and land abandonment can increase wildfire risk and ecological degradation, and why mobile pastoralism may be one of the most effective tools for conserving rangelands while producing food. The conversation critiques conventional life cycle assessments (LCAs), highlighting how “carbon tunnel vision” and simplistic accounting can lead to misguided policy recommendations. If you’re looking for a more nuanced, ecosystem-based perspective on livestock, climate change, and sustainable food systems, this episode offers a powerful reframing of the debate. Timestamps 00:00 Introduction to Livestock and Ecosystem Conservation 02:30 The Role of Herbivory in Ecosystem Dynamics 06:05 Understanding Baseline Emissions from Wild Herbivores 15:50 The Complexity of Livestock Emissions and Management 18:24 Comparative Emissions: Livestock vs. Wild Herbivores 24:58 Future of Herbivory: Rewilding and Ecosystem Restoration 26:28 Rewilding and Ecological Challenges 32:14 The Role of Livestock in Ecosystem Management 38:06 Food Security and Sustainable Practices 47:08 Rethinking Land Use and Emissions 52:04 Understanding Complexity in Nature Dr. Pablo Manzano X: https://x.com/PabloPastos LinkedIn: https://www.linkedin.com/in/pablo-manzano/ Basque Centre for Climate Change: https://www.bc3research.org/pablo_manzano Connect with Ty X: https://www.x.com/TyBealPhD LinkedIn: https://www.linkedin.com/in/tybeal Instagram: https://www.instagram.com/tybealphd Newsletter: https://www.tybeal.com

    The Case for Ethical Omnivorism | Frédéric Leroy, PhD

    In this episode, Frédéric Leroy, PhD, a professor of food science and biotechnology at the Free University of Brussels, joins the show to dismantle the polarized debate surrounding animal-source foods. We explore the nutritional risks associated with restrictive vegan diets, particularly for vulnerable groups like infants and women of reproductive age, while examining the evolutionary and biological role of meat in the human diet. Dr. Leroy challenges the current push toward exclusively plant-based global policies, discussing the limitations of the EAT-Lancet report and the "carbon tunnel vision" often applied to environmental sustainability. We also dig into the misunderstood science of saturated fat and processed meats, distinguishing between traditional preservation methods and modern ultra-processing. Dr. Leroy introduces the "Nourishment Table," a flexible, evidence-based framework for healthy eating that prioritizes nutrient density and minimizes ultra-processed foods. Finally, we discuss the concept of "ethical omnivorism" and how to balance animal welfare with the ecological realities of food production. If you want a nuanced, scientific perspective on the role of livestock in a healthy and sustainable future, this episode is for you.

    Evidence, Uncertainty, and Nutrition Science | Gordon Guyatt, MD

    What do we know about health, nutrition, and medicine — and how confident should we be? In this episode, Dr. Gordon Guyatt, the clinician-scientist who coined the term evidence-based medicine and co-created the GRADE framework, breaks down why so much health and nutrition guidance rests on weak foundations. We dig into the hierarchy of evidence, why observational studies so often mislead us, and what went wrong with hormone replacement therapy and antioxidant vitamins. Dr. Guyatt also explains the intense backlash to the NutriRECS red-meat guidelines and why overstating certainty erodes trust in both science and public health. We also explore the growing influence of health influencers, why acknowledging uncertainty is essential, and how AI could both help and harm evidence-based decision-making. From the limits of nutrition research to the future of trustworthy guidelines, this conversation offers a clear, honest look at what we know — and what we don’t. If you want rigorous, hype-free insight into how evidence should inform health decisions, this episode is for you. Timestamps 00:00 Introduction 01:10 What evidence-based medicine actually means 04:28 When low-quality evidence misleads (HRT, antioxidants) 07:29 Why most nutrition research is low certainty 11:29 The NutriRECS red-meat guidelines and backlash 17:55 How the nutrition field overstates certainty 21:02 Influencers and misinformation 23:42 AI’s role in evidence-based decision-making 31:58 Why uncertainty and humility matter 32:34 Advice for clinicians and researchers 37:14 How to make recommendations with low-quality evidence Dr. Gordon Guyatt X: https://x.com/GuyattGH LinkedIn: https://www.linkedin.com/in/guyattgh McMaster University: https://experts.mcmaster.ca/people/guyatt Connect with Ty X: https://www.x.com/TyBealPhD LinkedIn: https://www.linkedin.com/in/tybeal Instagram: https://www.instagram.com/tybealphd Newsletter: https://www.tybeal.com
