Foods and Habits That Keep Your Immune System Resilient

Many communities face an uneven food landscape: plenty of cheap junk food, but few places to buy fresh, healthy food. This pattern—often called “food apartheid”—doesn’t happen by accident; it grows from redlining, unfair rules, and corporate control. The impacts are steep: higher rates of type 2 diabetes, kidney failure, and learning problems in Black, Latino, and Indigenous communities, along with unsafe conditions for farmworkers. These harms have a long history, and government subsidies and convincing marketing keep ultraprocessed foods on top. However, we take practical steps to make change including investing in regenerative and community farms, protecting and fairly paying farmworkers, and enforcing civil-rights laws so public dollars support real food, healthy soil, and communities that thrive. In this episode, Leah Penniman, Dr. Rupa Marya, Raj Patel, Karen Washington, and I discuss why food injustices exist and how we can create regenerative food systems to serve everyone. Leah Penniman is a Black Kreyol educator, farmer/peyizan, author, and food justice activist from Soul Fire Farm in Grafton, NY. She co-founded Soul Fire Farm in 2010 with the mission to end racism in the food system and reclaim our ancestral connection to land. As co-Executive Director, Leah is part of a team that facilitates powerful food sovereignty programs - including farmer training for Black & Brown people, a subsidized farm food distribution program for communities living under food apartheid, and domestic and international organizing toward equity in the food system. Leah has been farming since 1996, holds an MA in Education and a BA in Environmental Science from Clark University, and is a Manye (Queen Mother) in Vodun.  Dr. Rupa Marya is a physician, activist, mother, and composer. She is an Associate Professor of Medicine at the University of California, San Francisco where she practices and teaches Internal Medicine. Her research examines the health impacts of social systems, from agriculture to policing. She is a co-founder of the Do No Harm Coalition, a collective of health workers committed to addressing disease through structural change. At the invitation of Lakota health leaders, she is currently helping to set up the Mni Wiconi Health Clinic and Farm at Standing Rock in order to decolonize medicine and food.  Raj Patel is a Research Professor at the University of Texas at Austin’s Lyndon B Johnson School of Public Affairs, a professor in the University’s department of nutrition, and a Research Associate at Rhodes University, South Africa. He is the author of Stuffed and Starved, the New York Times bestselling The Value of Nothing, co-author of A History of the World in Seven Cheap Things. A James Beard Leadership Award winner, he is the co-director of the award-winning documentary about climate change and the food system, The Ants & The Grasshopper.  Karen is a farmer, activist, and food advocate. She is the Co-owner and Farmer at Rise & Root Farm in Chester, New York. In 2010, Karen Co-Founded Black Urban Growers (BUGS), an organization supporting growers in both urban and rural settings. In 2012, Ebony magazine voted her one of the 100 most influential African Americans in the country, and in 2014 Karen was the recipient of the James Beard Leadership Award. Karen serves on the boards of the New York Botanical Gardens, SoulFire Farm, the Mary Mitchell Center, Why Hunger, and Farm School NYC. This episode is brought to you by BIOptimizers.

Thyroid trouble often starts as a whisper—tiredness, stubborn weight, dry skin—until a closer look shows the tiny neck gland that sets the body’s “speed” is out of tune. Basic tests can miss the real issue, so checking active hormones and thyroid antibodies—and hunting for triggers like stress, gluten sensitivity, toxins, nutrient gaps, and gut imbalances—can reveal what’s really going on. When understood this way, thyroid health is no longer just about numbers on a lab report—it’s about restoring balance in the whole system. With the right testing, nutrition, and support, energy, mood, and metabolism can all return to their natural rhythm. In this episode, I discuss, along with Dr. Elizabeth Boham and Dr. George Papanicolaou, thyroid conditions such as hypothyroidism, hyperthyroidism, thyroid autoimmunity and how Functional Medicine practitioners take a different approach to find the root cause of the imbalance. Dr. Elizabeth Boham is Board Certified in Family Medicine from Albany Medical School, and she is an Institute for Functional Medicine Certified Practitioner and the Medical Director of The UltraWellness Center. Dr. Boham lectures on a variety of topics, including Women’s Health and Breast Cancer Prevention, insulin resistance, heart health, weight control and allergies. She is on the faculty for the Institute for Functional Medicine. Dr. George Papanicolaou is a graduate of the Philadelphia College of Osteopathic Medicine and is Board Certified in Family Medicine from Abington Memorial Hospital. Over time as the healthcare system made it harder for patients to receive personal care, Dr. Papanicolaou decided a change was needed. He began training in Functional Medicine through the Institute of Functional Medicine. In 2015, he established Cornerstone Personal Health—a practice dedicated entirely to Functional Medicine. In August 2017, I invited Dr. Papanicolaou to join The UltraWellness Center and we’ve been successfully helping people together ever since. This episode is brought to you by BIOptimizers.

For too long, psychiatry has treated mental illness as if it lives only in the brain. But what if the real story begins in the body? My guest today, Dr. Shebani Sethi, is a Clinical Associate Professor at Stanford and founding director of the Metabolic Psychiatry Program, the first clinic to unite psychiatry with nutrition and metabolism. On this revealing episode of The Dr. Hyman Show, we explore how shifts in metabolism affect the brain and why this whole-body lens could transform how we prevent, understand, and treat mental health. Watch the full conversation on YouTube, or listen wherever you get your podcasts. We discuss: • How to recognize metabolic red flags behind mood and focus • Tests you can ask for to uncover hidden drivers of mental health • Everyday steps to restore brain energy and resilience • Foods and nutrients that calm inflammation and support cognition Dr. Shebani Sethi coined the term Metabolic Psychiatry, capturing what I’ve long believed and explored: that mental health begins in the body. Embracing this shift could reshape how we treat the mind and how we live each day.
