It is generally admitted that a diet rich in omega-3 fatty acids decreases the risk of cardiovascular events, see 1,2,3, and could perhaps prolong the lifetime.
According to the JAMA of January 20th, 2010 the shortening of telomeres (measured into leukocytes at 6 years interval), was slowed down in people having a high blood level of omega-3 fatty acids, EPA and DHA.
These results are to be taken with some reluctance because the concentration of omega-3 fatty acids was measured only once and in addition there was not correlation between the length of telomeres and omega-3 fatty acids at baseline. The question telomere length as an ageing marker is not very simple; see for example this paper "Telomere diseases" in the NEJM of December 10th, 2009.
