Episode 277: Dr. Rachel Herz | The Science of Disgust, Smell, and Why You Eat What You Eat

Neuroscientist Dr. Rachel Herz, an expert on the psychology of smell, discusses how disgust is mostly a learned response and how ultra-processed foods are engineered to bypass our natural “this isn’t real food” signals. She and Dr. Vera Tarman explore the links between smell, memory, and eating behavior, and touch on where Herz’s more psychological view of disordered eating differs from the addiction model.
