On this week's episode, Brent is joined by Dr. Barry Popkin, a leading nutrition researcher known for his work on ultra-processed foods and global diet trends. Dr. Popkin explains how modern food systems have reshaped what we eat, why ultra-processed foods are linked to obesity, diabetes, and heart disease, and how liquid calories and added sugars uniquely drive metabolic harm. The conversation also examines the political and industry forces that shape food policy in the U.S., including regulation, lobbying, and why meaningful dietary reform has been so difficult to implement. Hope you enjoy.
