In this episode, host Tricia Friedman sits down with Dr. Michael Greger, bestselling author and founder of NutritionFacts.org, to explore why non-commercial, evidence-based health guidance matters more than ever. They discuss lifestyle medicine, plant-based nutrition, scientific integrity, cannabis research, and how small, testable behavior changes can dramatically improve long-term health.
What This Conversation Is Really About
Health advice is everywhere — but trustworthy guidance is not. This conversation slows things down and examines how to make informed choices in a noisy, commercialized health landscape, without absolutism, hype, or fear-based messaging.

Why he donates 100% of book proceeds to charity
-
How lifestyle medicine transformed his own family's health
-
What the science actually says about cannabis — both risks and benefits
-
Why updating guidance as evidence evolves is a strength, not a weakness
-
How social support, not willpower, determines whether health changes last
