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.
