Dr. Oz's Anti-Aging Checklist

Dr. Oz says one of his favorite anti-aging foods are blueberries. You can tell blueberries are chockfull of antioxidants because of their dark color. "All foods with dark colors in them have some of these really protecting antioxidant chemicals in them," he says. "Blueberries lead the charge."

Other good anti-aging foods include sweet potatoes, broccoli and tomatoes. "[When eating] tomatoes, heat them up a little bit and put a little oil in them. It makes it easier to absorb the lycopene," Dr. Oz says. "Lycopene is another antioxidant, but it has additional benefits as well, which are particularly valuable for the heart."

While he's mentioned many of these antioxidant-rich foods before, Dr. Oz is ready to introduce a new entry to his hall of fame—the acai (pronounced "AH-sigh-EE"), a small fruit from South American rainforests that is often found in the United States in juice. "It has twice the antioxidant content as a blueberry, so it's a wonderful alternative," Dr. Oz says. "Look at the food label and make sure they don't have too many carbohydrates in there. It's available in all major stores now. It's just sort of breaking through."
