Researchers have long known that resveratrol—a substance commonly found in red wine, peanuts, and grapes—acts as a potent antioxidant, sweeping up free radicals that damage cells and increase the risk of cancer, heart disease, and brain diseases such as Alzheimer's disease.

But up until recently, little was known about how resveratrol works to slow the aging process and maximize lifespan. Researchers have now discovered this powerful phytonutrient influences age-regulating genes, allowing cells to live longer.

In a recent study published in Nature, scientists found resveratrol mimics calorie restriction in yeast -- activating specific enzymes that slow aging and preserving the stability of DNA.
