Tomatoes are high in important antioxidants such as vitamin C and Vitamin A. These vitamins work to fend of DNA damage from free radicals. Consequently, tomatoes may help to ward off age related diseases such as atherosclerosis and diabetes. Lycopene, a flavonoid antioxidant, is an unique phytochemical present in the tomatoes. Red varieties are especially concentrated in this antioxidant. Together with carotenoids, lycopene may help protect cells and other structures in the human body from harmful oxygen free radicals. Studies have shown that lycopene protects the skin from ultra violet (UV) rays and thus offers some defence against skin cancer.
