(NaturalNews) As NaturalNews has previously reported, omega-3s, the fatty acids found primarily in cold water fish like salmon, have a host of health benefits, including alleviating depression, preventing age-related blindness and protecting against prostate cancer. And now there's evidence omega-3s may have a profound anti-aging effect, too.

Telomeres, structures at the end of chromosomes that are involved in the stability and replication of chromosomes, are markers of biological aging. Genetic factors, exposure to certain chemicals and environmental stressors shorten the length of telomeres and are believed to contribute to the aging process. New research just published in the Journal of the American Medical Association (JAMA) shows that omega-3s slow down the shortening of telomeres -- this means omega-3 fatty acids may protect against aging on a cellular level.

Previous studies have shown that people with established cardiovascular disease who have a high dietary intake of marine omega-3 fatty acids live longer than others with the same health problems who do not have adequate omega-3s in their diet. However, the exact way omega-3s exert this protective effect is not well understood, according to background information in the JAMA study.
