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?
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®.
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.
