Food Junkies Podcast Episode 238: Dr. Raphael E. Cuomo, Ph.D. - Addiction, Cancer & the Biology of Compulsion
In today’s episode, we explore the groundbreaking intersection of addiction, biology, and cancer with internationally recognized scientist Dr. Rafael Cuomo. Drawing on insights from his book Crave, Dr. Cuomo reveals how addiction is not simply a behavioral or psychological issue—it’s a biological condition that reshapes the terrain of our health and directly contributes to the development of chronic disease, including cancer.
Dr. Cuomo introduces the concept of “molecular scars”—long-term physiological changes left behind by repeated addictive behaviors, even low-grade ones like screen use or ultra-processed food consumption. He explains how these behaviors disrupt key systems in the body, including the dopamine, opioid, GABA, glutamate, cortisol, and the endocannabinoid systems, ultimately weakening immune surveillance, fueling inflammation, and accelerating cellular damage.
From the anticipatory nature of craving to the role of trauma and adverse childhood experiences, this episode invites clinicians, patients, and everyday listeners to reconsider addiction not as a character flaw, but as a biologically driven imbalance with profound public health implications.

Dr. Rafael Cuomo is a biomedical scientist, global health researcher, and associate professor at the University of California, San Diego School of Medicine. With over 100 peer-reviewed publications and recognition from the Royal Society for Public Health, his work focuses on the biological intersections between addiction, cancer prevention, and public health policy. His new book, Crave: The Hidden Biology of Addiction and Cancer, uncovers how repeated behavioral addictions create a biological terrain that promotes chronic disease—and offers a new roadmap for prevention and healing.
📖 Key Quotes from Dr. Rafael Cuomo:“Addiction doesn’t just leave behavioral scars—it leaves molecular scars that change how your body functions.”
“Cravings aren’t your character—they’re signals. And once we learn to listen to those signals, we can start rewriting our story.”
“We need to shift prevention efforts upstream—not just focusing on behaviors, but addressing the mindset and environment that drive those behaviors.”
“Chronic overstimulation from food, screens, and stress narrows our ability to feel genuine reward—leading to emotional flatness and compulsive seeking.”
