Association of Nutrients with Biomarkers of Alzheimer's Disease.

Prospective cohort studies, cross-sectional surveys, autopsy studies and intervention clinical trials that investigated the association between nutrients and Alzheimer's disease (AD) have been reviewed. To estimate the relationship between specific nutrient intake and the risk of AD, Cochrane Library, PubMed, EMBASE, and the Fisher Center for Alzheimer's Research Foundation were searched for this purpose. Most published observational studies found an inverse relationship between vitamins, n-3 fatty acids and AD.
