Juicy and tart Montmorency cherries are your best source of the antioxidant melatonin. Other cherries have it, too, but Montmorency has the most. Melatonin protects the skin against ultraviolet radiation. Researchers have discovered that this powerful little nutrient also helps repair sunburned skin, since it stimulates new skin-cell growth. Cherries are also packed with vitamin C, which is needed to build collagen—your skin’s natural “scaffolding” and a wrinkle preventer.

Brussels sprouts

These broccoli cousins have plenty of bitter sulforaphane as well as compounds called isothiocyanates, which detoxify cancer-causing substances in the body before they can do their dirty work. In one Dutch study, guys who ate brussels sprouts daily for three weeks had 28 per cent less genetic damage (gene damage is a root cause of cancer) than those who didn’t eat sprouts.
