Taking enough omega-3 fatty acid supplements over a four month period to change the balance of oils in the diet could slow a key biological process linked to aging, new research suggests.
The study showed that most overweight but healthy middle-aged and older adults who took omega-3 supplements for four months altered a ratio of their fatty acid consumption in a way that helped preserve telomeres, tiny segments of DNA that when shortened, are known to cause aging.
Omega-3 supplementation also reduced oxidative stress, caused by excessive free radicals in the blood, by about 15 percent compared to effects seen in the placebo group.
People with diets high in vitamins C, D, E and the B vitamins and omega 3 fatty acids are less likely to experience brain shrinkage associated with Alzheimer’s disease than people whose diets are not high in those nutrients, according to a new study published in the December 28, 2011, online issue of Neurology®.
Aging is often associated with undesirable events, like wrinkles, tiredness, disease. While everyone ages, some people seem to age more gracefully then others. Could good nutrition be the key to a healthier, longer life?
