Dr. Nancy Keller on Mold and Mycotoxins

This week, Brent sits down with Dr. Nancy Keller, one of the world's leading experts on fungi and mycotoxins, to explore how mold actually affects human health. Dr. Keller explains how certain fungi produce toxic compounds that can contaminate crops like peanuts, corn, and apples, why improper food storage is often the real culprit, and how modern food systems work to reduce those risks. The conversation examines the difference between visible mold and invisible mycotoxins, the surprising ways fungi use these chemicals to compete with other microbes, and why some of the most dangerous exposures are concentrated in parts of the developing world. They also dive into the controversial topic of mold in homes, separating well-established risks from claims that remain scientifically uncertain. Dr. Keller is a wonderful guest with decades of experience in the field. Hope you enjoy.
