In this episode, Dr. Kelly Brogan sits down with Dr. Daniel Roytas—clinical educator, researcher, and author of Can You Catch a Cold?—to unravel one of the most deeply held beliefs in both mainstream and alternative health: the idea that parasites are invaders that must be eradicated. Daniel’s work challenges the foundations of germ theory and dives into the seductive psychology of victim consciousness that underpins much of modern medicine—yes, even “natural” medicine.
