Munching on broccoli spears may help thwart breast cancer.

Broccoli contains a compound that may retard the growth of breast cancer cells, a recent study suggested. The compound, called sulforaphane, is a potent antioxidant that stimulates cell detoxification. Add a new twist to this veggie favorite by stir-frying crisp broccoli spears in sesame oil and garlic.

All cruciferous vegetables -- including not only broccoli but also cauliflower, Brussels sprouts, and kale -- contain high levels of sulforaphane, a powerful antioxidant with cancer-fighting properties. In a recent study, sulforaphane was shown to inhibit the growth of breast cancer cells by interfering with the cells' ability to divide. Studies have potentially revealed a similar effect on prostate cancer cells. However, experts caution that no one food or compound can completely eliminate cancer risk. Your best bet to reduce your risk of cancer is to exercise regularly, maintain a healthy weight, and eat a variety of fruits, vegetables, and plenty of fiber.
