Omega-3s May Fend Off Age Related Disease
OK, maybe omega-3 fatty acids do nothing for heart health, but new research suggests that they may be good for something else that is near and dear to all of us: our lifespan. An Ohio State University news release reports that researchers at the school gave a group of more than 100 healthy but overweight people (two different) doses of omega-3 fatty acids made from cold water fish like salmon and cod. And yes, a control group got a placebo. After four months, the researchers found that those who took omega-3 supplements showed, on average, lengthening of telomeres, segments of DNA that shorten as we age, compared to those in the placebo group. When the researchers analyzed the participants’ omega-6 to omega-3 ratio in relationship to telomere lengthening, a lower ratio was clearly associated with lengthened telomeres. Does that mean that omega-3s can slow the aging process? In some small ways, yes: the researchers think they may reduce the risk of age-related disease. And wait, there’s more: Both omega-3 groups showed an average overall 15 percent reduction in oxidative stress compared to effects seen in the placebo group. Read more from Ohio State.
