Consider these foods your anti-aging staples. As a rule, fruits and vegetables high in flavonoids and carotenoids, two powerful plant-based antioxidants, will remove the free radicals from your skin and body that cause you to age prematurely. A well-balanced diet can help you lose weight, live longer and feel fitter. But it can also help you look younger. Forget the fountain of youth. Load up a plate at the feel-better buffet and turn back the clock on a full (and happy) stomach.
