Where Optimal Meets Practical 287: Akash Patel - Science vs Policy: The Dietary Guidelines Problem
The U.S. Dietary Guidelines are supposed to reflect the best available nutrition science… but what happens when the final recommendations don’t match the evidence?
In this episode, I’m joined by Akash Patel to break down how the Dietary Guidelines are created, where they diverged from the scientific report, and what this means for nutrition, public health, and your everyday food choices.
Akash Patel is an MD/MBA student at the University of Miami focused on nutrition, lifestyle medicine, and public health, with a focus on improving nutrition education in healthcare.
