Lycopene, belonging to the carotenoids, is abundantly found in tomatoes and tomato-based products, pink grapefruit, and watermelon. Asparagus and parsley despite not having red or orange color, also are good sources of lycopene.
Lycopene is a potent antioxidant-an important deactivator of reactive oxygen species. The human body cannot synthesize lycopene and therefore, it must be consumed with daily food. The absorbed lycopene is mostly stored in the testes, liver, adrenals, and prostate, with concentrations in the testes as high as 10 times that of other tissues. This may point to an exclusive biological role of lycopene in certain tissues.
