Health Shorts: A fishy way to slow aging

Heart patients with high blood levels of omega-3 fatty acids showed signs of slower biological aging at the cellular level, according to a study published in the Journal of the American Medical Association [January 20, 2010]. The most important omega-3 fatty acids, DHA and EPA, are found in fatty fish such as salmon and cod.

Patients with the highest levels of omega-3 fats showed the least shortening of telomeres, a sign of biological aging. The authors pointed out that a cause-effect relationship was not established. The patients with high levels of omega-3s may have had other healthy habits that influenced the results.
