Lycopene is an antioxidant that fights against cancer. It gives tomatoes, watermelons, pink grapefruit and other vegetables their red color. Lycopene has been shown to inhibit the growth of many types of cancer cells. In fact, men who eat pizza have been found to have a reduced risk of prostate cancer because of the lycopene- rich tomato sauce. Lycopene has also been found to protect against the carcinogens in tobacco smoke and exposure to the sun's ultraviolet rays.
New research shows that it helps prevent heart disease as well.
