Is dementia simply the result of ageing and genetics, or could modern food be contributing decades before symptoms appear? Dr. Eric Westman reacts to Dr. Anthony Chaffee’s argument that high-sugar, nutrient-poor diets may starve the brain of ketones, cholesterol and key animal-based nutrients.
The discussion covers insulin resistance, Alzheimer’s as “type 3 diabetes,” ketones as an alternative brain fuel, statins and memory concerns, B12, animal nutrients and early ketogenic-diet studies in Alzheimer’s and Parkinson’s disease. Dr. Westman finds the evidence promising but cautions that many trials remain small.
