The Daily Habits That Protect Your Brain At Any Age: The New Science Of Dementia Prevention with Dr David Perlmutter #674
Dr. David Perlmutter explains that dementia is not an inevitable part of aging but the result of decades of metabolic damage. He reveals the critical role of microglial cells in protecting or damaging the brain, and how diet and lifestyle can keep them in a protective state. He discusses how ultra-processed food triggers neuroinflammation and outlines key blood biomarkers—fasting insulin, homocysteine, and uric acid—that offer a window into long-term brain health.
