The tree tomato is an excellent source of antioxidants because it contains a type of flavonoid known as anthocyanins. Furthermore, and more importantly it contains the carotenoids lycopene and beta carotene. Free radicals are the cause of chronic diseases such as cardiovascular disease and cancer. Moreover, numerous invitro studies have demonstrated that lycopene is particularly effective against prostate cancer. Lycopene, along with the other carotenoids, betacorotene, lutein and zeaxanthin, help protect and repair cells against DNA damage, thereby helping to prevent premature aging. However, of the four carotenoids, lycopene has by far the most antioxidant activity.
