Demonized by Design: The Science Behind Why High Fructose Corn Syrup, MSG, Seed Oils, Soy, Eggs, and Dietary Cholesterol Aren't the Villains You Think They Are

from Why's That, Dad? | The Science, History & Culture of Everyday Questions for Curious Adults and Kids · host Phillip.paulsen

From "No HFCS!" labels to MSG paranoia to fifty years of egg guilt, food fear has become a multi-billion-dollar marketing industry — and most of us have fallen for it. In this episode, we trace the real science, flawed studies, and deliberate PR campaigns behind some of the most demonized ingredients in the modern diet: high fructose corn syrup, monosodium glutamate, seed oils, phytoestrogens in soy, and dietary cholesterol — with eggs as the most dramatic case study of official nutrition science getting it badly wrong for half a century. We examine how regulatory science works, why the body self-regulates cholesterol in ways most people don't know, and how industry manipulation shaped what hundreds of millions of people ate for decades. By the end, you'll have a sharper, more skeptical toolkit for reading nutrition headlines — and probably a guilt-free breakfast tomorrow.
