Lycopene is currently the most powerful antioxidant which has been measured in food (2) and is thought to play a role in preventing cancer, heart disease, and macular degeneration (3,4,5,6,7,8). How large a protective role lycopene plays is a controversial issue which is still under scientific study.
Lycopene is a carotenoid that gives many fruits and vegetables their red color, eating lycopene in excess amounts can cause the skin and liver to have a yellow color. Unlike other carotenes, lycopene does not get converted into vitamin A.
There are no known symptoms of a lycopene deficiency, and no daily value (DV) for lycopene.
Foods high in lycopene include guavas, cooked tomatoes, watermelon, grapefruit, papaya, sweet red peppers, persimmon, asparagus, red cabbage, and mangos. (1)
