SIRT1 - DNA Protection & Repair

From USNews:
...maintain their telomerase levels: switching from regular to nonfat dairy products, adding two or three servings of fruits and vegetables to their diet, or doing just a few minutes of daily meditation, for example. The same may be true for other longevity boosters such as calorie restriction, which is thought to extend life span by boosting SIRT1, a protein involved in protecting and repairing DNA (and thus protecting against potential killers like heart disease and cancer). Cutting calorie intake by a hunger-pang-producing one third might help people live about 20 percent longer, suggests David Sinclair, a professor of pathology at Harvard Medical School who conducted studies, similar to the monkey one, in mice. He says reducing calories by a smaller amount—say, 50 calories a day—could moderately boost SIRT1.

Telomerase

From USNews:Even if you've been slipping up until now, making healthful changes today can turn back the clock—or at least slow it down. Ornish's research has found that a low-fat diet, regular exercise, and relaxation techniques all work in synergy to increase levels of telomerase, an enzyme thought to slow cellular aging and prevent healthy cells from turning cancerous. Specifically, he found that telomerase was boosted by 30 percent in prostate cancer patients who followed a plant-based, whole-grain diet with very little fat or sugar for three months. The men also took fish oil supplements, did daily 30-minute bouts of exercise, and practiced yoga or meditation for an hour a day. "Telomerase turns up those genes associated with disease prevention and turns down the genes associated with heart disease, diabetes, and cancer," explains Ornish.
