fS-Lykop ATK 7016
Lycopene is a red pigment, belonging to the carotenoid group, found in e.g. tomatoes. Other compounds of the same group include alfa- and beta-carotene. Several studies have found that high lycopene intake protects from cancer and cardiovascular disease. Sources of lycopene include tomato, watermelon, red grapefruit and rose hip. Like other carotenoids, the most efficient absorption of lycopene is achieved from processed foods. Grinding and cooking significantly enhance its absorption. Good lycopene sources thus include e.g. ketchup, tomato juice or pureed tomato rather than fresh tomatoes.
