Dr. Michael Greger has spent his career translating nutrition research most people never see into practical, evidence-based advice. That mission was front and center when Dr. Michael Greger joined Sean Kelly on the Digital Social Hour to talk about the outsized role diet plays in chronic disease and early death.
The conversation covers a lot of ground quickly, moving from the evidence behind plant-based eating to practical questions about supplements, sleep, and everyday habits, all through the lens of a physician who has built his career on reading the underlying research rather than following food trends.
