Sweet Potatoes
Beta-carotene is a powerful antioxidant. Studies have shown that people who eat a diet high in beta-carotene — found primarily in orange vegetables and leafy greens — have a reduced risk of cancer, particularly of the lung, colon, and stomach. Among premenopausal women, one study found that eating a lot of vegetables that include beta-carotene, folate, vitamin C, and fiber – like sweet potatoes — reduced the risk of breast cancer by about half.
Peanuts and Peanut Butter
Some research shows that eating a vitamin E–rich diet reduces the risk of stomach, colon, lung, liver, and other cancers, but, as with other antioxidants, vitamin E supplements have largely struck out. I recommend adding vitamin E–rich foods like peanuts, peanut butter, almonds, almond butter, and sunflower seeds to your diet; they’ll help keep your cells’ defenses strong. Spread a tablespoon of peanut butter or almond butter on a slice of whole grain toast for a filling snack packed with cancer-fighting vitamin E.
