In this podcast episode, Dr. Mark Hyman explores the vital role of polyphenols in supporting our immune system. He explains that these compounds, abundant in plant-based foods, act as gentle stressors that enhance our body's defenses through a process known as hormesis. Dr. Hyman highlights key polyphenols, such as catechins found in green tea and dark chocolate, quercetin present in various fruits and vegetables (especially Himalayan Tartary Buckwheat), and rutin, which is also in Himalayan Tartary Buckwheat. He discusses their antiviral, anti-inflammatory, and antioxidant benefits. The episode underscores how polyphenols contribute to gut health by nourishing beneficial gut bacteria and reinforcing the gut barrier, ultimately boosting immunity and lowering the risk of illnesses like colds and the flu. Additionally, Dr. Hyman emphasizes the significance of vitamin C and zinc for immune function, recommending both dietary sources and supplements.
