This interview podcast features Max Lugavere interviewing Dr. William Li about food as medicine for longevity. The conversation begins by defining longevity as living long and well, then discusses common diseases that shorten lifespan (diabetes, cancer, cardiovascular disease) and how to mitigate them. Dr. Li emphasizes simple, actionable steps like eating whole, fresh foods, portion control, and occasional meal skipping to reset metabolism. He also highlights the importance of dietary diversity, including various protein sources and less-processed options, and cautions against ultra-processed foods by advising listeners to check ingredient labels. Finally, the discussion touches on the benefits of various foods (strawberries, cruciferous vegetables, mushrooms, coffee) and the importance of muscle health and regular exercise for both physical and mental well-being.
