The rise in diseases like Parkinson's and Alzheimer's could have a surprising source: the gut. Scientists are still exploring the link between the gut and the brain, but there is evidence that a balanced holistic lifestyle could reduce stress, inflammation, and, potentially, the risk of neurodegenerative conditions.

On this episode of On Nutrition, we talk with gastroenterologist Dr. Partha Nandi about his new book, "Heal Your Gut, Save Your Brain: The Five Pillars of Enhancing Your Gut and Optimizing Your Cognitive Health."
