Calorie restriction may prevent Alzheimer's through promotion of longevity program in the brain

...s which influence a variety of functions including metabolism and aging. Dr. Pasinetti and colleagues used an experimental mouse model to demonstrate that beta-amyloid peptides in the brain can be reduced by subjecting the mice to dietary caloric restriction, primarily based on low carbohydrate food. Conversely...
