Eating fish delays Alzheimer's disease – Alzheimer prevention by eating fish – sea food

A recent study has revealed that docosahexaenoic acid (DHA) which is a kind of omega-3 fatty acid may slow the growth of two brain lesions that are the core causes of Alzheimer's disease.

The most common and widely available source of DHA is cold water oily fishes.

Researchers found that DHA works better on its own than when paired with omega-6 fatty acids.

The study also determined the mechanism by which DHA leads to lower levels of beta amyloid.

DHA leads to lower levels of presenilin, an enzyme responsible for cutting beta amyloid from its parent, the amyloid precursor protein. Without presenilin, beta amyloid cannot be generated.
