Study: Omega-3 Supplements May Actually Affect Aging
PROBLEM: It's an eternal and irreversible certainty that as we get older, our telomeres shorten. Every time a cell divides, a bit of the chromosomal end-piece is clipped off, our DNA diminishing in length; aging, cancer, and our ultimate demise following closely behind. If we can't preserve our fleeting youth, can we at least save our telomeres? And -- let's be honest, here -- can we do so without making any major lifestyle changes?
METHODOLOGY: Researchers at Ohio State University put adults (over one hundred of them, middle-aged and older, mostly overweight but otherwise healthy) on a four month regimen of already-known-to-be-good-for-us omega-3 supplements. The pills, derived from cold-water fish like salmon and cod, were administered in two different doses, while a control group received placebos.
RESULTS: Members of both groups given the real stuff had longer telomeres than the sugar pill group -- a promising sign. But differences in telomere length reached statistical significance when looked at as a function of the lowered ratios of omega-6 fatty acids to omega-3 in the experimental groups' blood.
The fish pill groups also had a 15 percent reduction in oxidative stress, the disease-causing condition behind science's much-enthused over endorsement of red wine and dark chocolate.
CONCLUSION: Getting enough omega-3 fatty acid to change the balance of oils in your system may help preserve the length of your telomeres, with the potential to reduce the risk of age-related diseases.
Already a big fish-oil fan. Interesting about the telomeres. The
Mediterranean Diet is about the best one out there. I follow it in spirit but still eat too much red meat.
