Jamie What is lycopene? • Solanum lycopersicum • Carotene • no pro-vitamin A activity • Long-chain structure with double bonds • more than other carotenoids • Not an essential nutrient
Jamie What is lycopene? • Pigment naturally in foods and also used as a food coloring • Excess is not thought to be harmful, but can cause lycopenodermia
Niraja In foods • Lycopene is found in red/pink fruits and vegetables • Best sources: • Tomatoes • Watermelon • Pink grapefruit • Guava • Papaya • Red bell pepper • Also in: apricots, sea buckthorn, wolfberry (or goji, a berry relative of tomato), and rosehip.
Niraja In the body • Most common carotenoid in the human • Naturally present in human serum and tissues in higher concentrations than the other carotenoids • Fat soluble, so it concentrates in LDL and VLDL • Also found in adrenal glands, liver, testes, colon, and prostate • However, unlike other carotenoids, lycopene levels in serum or tissues do not correlate well with overall intake of fruits and vegetables.
Tobias Health BenefitsAntioxidant-blocks the action of free radicals, molecules that can damage cells • Helps fight degenerative diseases • lycopene may lower the risk of heart disease and macular degenerative disease, an age-related illness that can lead to blindness • Anti-inflammatory • may lower the risk of lipid oxidation, “the damage to normal fat molecules that can cause inflammation and disease” • Increased protective effect • “Said to lower LDL levels, enhance the body’s defenses, and protect enzymes, DNA, and cellular fats” (cancer.org)
Tobias Health Benefits Cancer Prevention and Treatment • More research is needed • Many studies found that those who ate diets high in lycopene appear to have lower risk for certain types of cancers • Evidence for a benefit was strongest in prostate, lung, and stomach cancer studies (possible benefits for pancreas, colon, cervix, breast, esophagus also) (JNCI) • “Numerous studies correlate high intake of lycopene-containing foods or high lycopene serum levels with reduced incidence of cancer, cardiovascular disease, and macular degeneration. However, estimates of lycopene consumption have been based on reported tomato intake, not on the use of lycopene supplements. Since tomatoes are sources of other nutrients, including vitamin C, folate, and potassium, it is not clear that lycopene itself is beneficial.” (mayoclinic.com)
