Possible link between omega-3s and longevity

Omega-3 fatty acids are oils found in fatty fish such as salmon. They're thought to help people with heart disease live longer. Now researchers reporting in the Journal of the American Medical Association think they may know part of the reason why. Higher fish oil levels in the blood may protect the caps on DNA called telomeres. That raises the possibility that these healthy fats could slow biological aging.

Telomeres protect valuable genetic material that helps keep the body young. Those with the lowest levels of omega -3 fatty acids had shorter looking telomeres, suggesting these patients were aging faster.
