The Hype vs. Data on Saturated Fat, Red Meat, & Seed Oils

What should you eat when everyone disagrees about nutrition? In this episode, Dr. Dariush Mozaffarian, cardiologist and director of the Food is Medicine Institute at Tufts, joins Dr. Rhonda Patrick to reexamine the evidence on saturated fat, red meat, seed oils, and the true drivers behind the obesity epidemic. He also explains how the GRAS loophole allows food companies to introduce additives without FDA review, and makes the case for using healthcare dollars to expand access to nutritious, minimally processed foods.
