Maybe…we don’t know yet. From a recent scientific article:
•Impaired brain glucose metabolism and amyloid β plaques are associated with Alzheimer’s disease pathology.
•Ketones provide an alternative metabolic precursor to glucose in the brain.
•Ketogenic diets likely reduce amyloid plaques and may reverse their neurotoxicity.
•Modern diets high in carbohydrates may contribute to increasing Alzheimer’s incidence.
•The ketogenic diet (including carbohydrate restriction) might be useful in the management of Alzheimer’s disease.”
