In this wide-ranging and deeply informative episode, Sean A. Russell welcomes Dr. Neal Barnard, physician, author, and president of the Physicians Committee for Responsible Medicine, for a science-backed conversation answering the most common questions about plant-based living. Dr. Barnard explains how food functions as medicine, breaks down the role of animal products in chronic disease, highlights the power of fiber, and shows how a whole-food, plant-based lifestyle can prevent and even reverse conditions like type 2 diabetes, high blood pressure, and hormone-related cancers. The discussion also tackles controversial topics, including soy, dairy, eggs, cholesterol, pregnancy, autoimmune conditions, and meal timing, all while grounding the conversation in compassion, environmental responsibility, and long-term health for future generations.
