Omega-3 fatty acids and brain health

A recent study published in the Journal of the American Heart Association looked at the relationship between consumption of omega-3 polyunsaturated fatty acids and some physical measures of the brain that have been linked to “brain health” and “cognitive health.” This research was a bit different from many other studies of omega-3 fatty acids and potential health benefits, because most other studies have looked for relationships between dietary intake of these compounds (found especially in deep water fish like salmon, sardines, tuna, and mackerel) and major health outcomes, such as cardiovascular disease or depression. The JAHA article, on the other hand, narrowed the focus by examining measurable small-scale physical changes in the brain over a period as long as five years.

The results: people with higher omega-3 fatty acid levels showed a significantly lower number of the small-scale physical brain changes that may be associated with brain dysfunction or cognitive decline.
The study authors concluded that, among the older men and women who were the study’s subjects, higher blood levels of omega-3 fatty acids, “and in particular DHA, were associated with specific findings consistent with better brain health.”

Our comment: a fascinating study, because it adds another level of evidence contributing to the already widely accepted view that omega-3 fatty acids are beneficial for your brain, and indeed may provide important help in maintaining brain function as you age.

See the NYBC catalog for a selection of fatty acids, and note especially the Nordic Naturals Pro Omega choices, which are excellent quality fish oil supplements, containing the omega-3 polyunsaturated fatty acids studied in the JAHA article:

Of special interest is the Jarrow supplement Max DHA, which provides an enhanced dose of the omega-3 fatty acid often associated with brain health:
