Results from a recent study published in the Journal of the American Medical Association, showed that omega-3 supplements did not slow cognitive decline in 4,000 older patients that were followed over a five-year period. These results are divergent with some evidence indicating that a diet high in omega-3 fatty acids can protect brain health. “Contrary to popular belief, we didn’t see any benefit of omega-3 supplements for stopping cognitive decline,” said Emily Chew, M.D., deputy director of the Division of Epidemiology and Clinical Applications and deputy clinical director at the National Eye Institute (NEI), part of the NIH. The Age-Related Eye Disease Study (AREDS), led by Dr. Chew, investigated a combination of nutritional supplements for slowing age-related macular degeneration (AMD), one of the main causes of vision loss in older Americans. Results from that study showed that daily consumption of high doses of certain minerals and antioxidants (the AREDS formulation), could slow progression of AMD. In a subsequent study named AREDS2, the team of researchers examined the effects of adding omega-3 fatty acids to the original formulation. However, the results showed no significant differences. Previous studies that surveyed health and diet habits concluded that regular consumption of fish (rich in Omega 3-fatty-acids) was linked to lower rates of AMD, cardiovascular disease, and poss
