Calorie restriction preventing Alzheimer’s
A Mount Sinai School of Medicine study indicates that caloric restriction helps “calm or even reverse symptoms of Alzheimer’s Disease (AD)”.
This study is the first to suggest that caloric restriction through promotion of SIRT1 (a molecule associated with brain longevity) may initiate a cascade of events like the activation of alpha-secretase which can prevent AD amyloid neuropathology. Since alpha-secretase is known also to inhibit the generation of beta-amyloid peptides in the AD affected brain, the study demonstrates a mechanism by which dietary caloric restriction might benefit AD. Most remarkably, the study finds that a high caloric intake based on saturated fat promotes AD type beta-amyloidosis, while caloric restriction based on reduced carbohydrate intake is able to prevent it.
