An essential nutrient found in fish oil does not appear to slow the mental decline associated with Alzheimer’s disease, according to a new study in the Journal of the American Medical Association.
The study is merely the latest to cast doubt on the mental benefits of the omega-3 fatty acid docosahexaenoic acid (DHA), which until recently was considered a promising way to minimize the risk and damage of dementia. (The other main ingredient found in fish oil, eicosapentaenoic acid, or EPA, is not believed to play a significant role in brain health.)
