Foods and Habits That Keep Your Immune System Resilient
The Dr. Hyman Show
Why Phytochemicals Trigger Healing Responses
Mark Hyman explains phytohormesis: plant defense polyphenols induce mild stress that upregulates human cellular repair and longevity pathways.
Our immune systems are under more pressure than ever—from processed diets, environmental toxins, stress, and fast-spreading infections—and the result is faster aging and greater vulnerability to disease. As we grow older, “zombie cells” spread inflammation throughout the body, weakening defenses and accelerating decline. But research shows we’re not powerless: the emerging science of immuno-rejuvenation reveals that we can retrain and rebuild our immunity. Through the right foods, lifestyle habits, and even strategic stressors, the body has hidden pathways for repair and renewal—offering clues to how we might slow aging and unlock greater resilience.
In this episode, I discuss, along with Dr. Elizabeth Boham and Dr. Roger Seheult, how we can support the immune system by using food, lifestyle, and hormetic stress to reduce illness and restore resilience while slowing aging.
