## Resource

Did you know that populations that primarily eat plant-based diets have dramatically lower rates of dementia? In this episode, Dr. Michael Greger, a renowned physician and author, shares groundbreaking research on how nutrition, particularly plant-based diets, affects Alzheimer's prevention. We examine the science behind heart-healthy, brain-boosting foods, emphasizing the importance of a whole-food, plant-based diet for overall well-being. You’ll learn how simple dietary changes can alter the course of cognitive health and how the latest studies are reshaping our understanding of brain aging. Whether you’re looking to prevent Alzheimer’s or simply optimize your brain health, Dr. Greger offers actionable advice supported by decades of research. Tune in to discover how small changes in your diet can have a profound impact on your cognitive function and longevity. “Alzheimer's is related to the atherosclerotic buildup of plaque inside the intracranial arteries in the brain. So the same dietary changes that can help with cardiovascular health can also help with cognitive health. In other words, what's good for the heart is good for the head.” ~ Dr. Michael Greger, M.D. FACLM In this Episode 00:00 - Introduction to Dr. Michael Greger 02:28 - The importance of lifestyle for brain health 04:50 - How heart-healthy diets support brain health 06:40 - Practical tips for adopting a plant-based diet wherever you are 10:00 - The ketogenic diet debate 14:27 - How pollutants affect brain health 16:46 - The link between diabetes and Alzheimer's 22:04 - Dr. Greger's thoughts on lab testing 24:28 - Debunking common myths about plant-based eating 28:07 - How to stick to healthy habits 29:59 - Is fasting good for cognitive health?
