Summary
In this episode, I’m joined by Christopher Gardner and Ty Beal to break down the science and debate behind the latest U.S. Dietary Guidelines. We explore ultra-processed foods, protein recommendations, plant-based alternatives, and how nutrition evidence is interpreted when shaping national dietary advice. Despite disagreements on specific points, this conversation highlights how much common ground exists when scientists engage in open, constructive dialogue.
