Tomatoes and tomato sauces, juices and ketchup meet approximately 85% of the dietary intake of lycopene. Typical carotenoid, lycopene is a replaceable element in the human diet, but it possesses important biological significance. Lycopene is found in the blood (plasma), skin and liver, adrenal glands, lungs, prostate, and colon.
Lycopene has a strong antioxidant effect and clears the body from free radicals. Lycopene may be the most potent neutralizer of singlet oxygen - an unstable form of molecular oxygen responsible for the destructive effects of sunlight on organic matter. Upon exposure to UV light, singlet oxygen directly influences the aging of the skin. Studies have shown that the neutralizing effect of lycopene is 100 times more effective than vitamin E.
