Understanding Dietary Fats: MUFAs and PUFAs

In this episode, Dr. Jessica Steier and Dr. Sarah Scheinman welcome Dr. Christopher Labos to examine the controversial topic of seed oils in nutrition.

They investigate how seed oils became demonized in contemporary diet culture, analyzing claims about their alleged inflammatory properties and health impacts. The conversation extends to broader nutritional misconceptions, food processing methods, and the polarization of dietary choices.
