Researchers from the University of California in San Francisco found that among patients with stable coronary artery disease, there was an inverse relationship between blood levels of omega-3 fatty acids and telomere shortening, a marker of biological age. In other words, patients with the highest intakes of omega-3 fatty acids had the slowest rate of biological aging at the cellular level.
While the study provides insight on how omega-3 fatty acids can benefit people with exiting heart disease, its not clear if the results apply to healthy people as well. Further studies are also needed to find out just how much omega-3s have to be consumed to offer the level of protection seen in this study, since patients didn’t receive a supplement, and their dietary intake wasn’t documented.
The best dietary sources of omega-3 fatty acids include salmon, herring, sardines and mackerel. Plant-based sources of the fatty acid can be found in walnuts and flaxseeds.
