Lycopene
Why you need it: This chemical pigment, found in red fruits and vegetables, appears to have antioxidant properties. Some studies suggest that lycopene may help guard against a range of ailments, including heart disease and several different types of cancer.
Where to get it: Tomatoes are the best-known source of lycopene, and sure enough, tomato products—such as sauces, pastes, and purees—contain up to 75 mg per cup. Raw, unprocessed tomatoes aren’t as lycopene-rich, however, and watermelon actually contains more per serving: about 12 mg per wedge, versus about 3 mg per tomato.
