In this episode, Dr. Li explains why food can have real biological power, how certain foods tested against cancer drug models, and why the body is designed around balance rather than extreme “on” or “off” switches.
Dave and Dr. Li also explore centenarians, super agers, healthspan, and why the future of longevity may depend on measuring your own biology over time instead of following generic rules. The conversation then turns to one of the most important modern health threats: microplastics.
Dr. Li breaks down how microplastics in arteries, microplastics in brain tissue, microplastics in food, microplastics in chewing gum, and airborne plastics from the environment may affect inflammation, the gut microbiome, the blood brain barrier, and long-term brain health. They also discuss the surprising connection between smell, memory, stem cells, and Alzheimer’s disease.
