Tomato lycopene content by Ray Sahelian, M.D. Tomato health benefit
Botanically speaking, a tomato is a fruit since it is the ovary, together with its seeds, of a flowering plant. However, from a culinary perspective, the tomato is served as part of a main course of a meal, as are other vegetables, rather than at dessert. The term "vegetable" has no botanical meaning and is purely a culinary term.
Benefit of tomato plant and
lycopene
Tomatoes have many antioxidants including the popular lycopene. Is a
Lycopene supplement necessary for optimal health? If you have a high intake
of tomatoes and fruits such as pink grapefruit or watermelon that have a high
lycopene content, you may not need additional lycopene supplements. However, if
you shun tomato products, and hardly eat
watermelon, pink
grapefruit, or other lycopene containing foods, then a lycopene supplement could be of benefit to you. To
learn more about lycopene.
Lycopene content of tomato and
tomato products per 100 grams.
Tomato Juice has 9 mg; Tomato Ketchup 17 mg; Spaghetti Sauce about 16 mg; and
Tomato Paste has about 30 mg. In contract, a raw tomato has about 3 mg per 100
grams of fruit.
Buy organic tomatoes
Organic vegetables and fruits are healthier for you. For instance, two
flavonoids - quercetin and kaempferol - are found in higher amounts in organic
tomatoes.
Tomato research
Tomatoes, tomato products and lycopene in the
prevention and treatment of prostate cancer: do we have the evidence from
intervention studies?

Lycopene-rich foods such as fresh tomatoes and tomato products are discussed as
potential effectors in the prevention and therapy of prostate cancer. This
review provides an overview on the efficacy of supplementation with tomatoes,
tomato products and lycopene on appropriate surrogate endpoint biomarkers such
as DNA damage and metabolites of the insulin-like growth factor pathway in
healthy individuals and prostate cancer patients. Intervention studies show that
the daily consumption of one serving of tomatoes or tomato products, but not
supplementation with lycopene alone, increases the resistance of mononuclear
leukocytes against DNA strand breaks induced by reactive oxygen species in
healthy volunteers. Data from clinical trials with prostate cancer patients are
scarce and contradictory. There is a paucity of reliable data on DNA damage in
prostate tissue. Increasing evidence suggests that a single serving of tomatoes
or tomato products ingested daily may contribute to protect from DNA damage. As
DNA damage seems to be involved in the pathogenesis of prostate cancer, the
regular ingestion of tomatoes or tomato products might prevent the disease.
Further well-designed studies are necessary to establish the role of tomatoes
and tomato products in the prevention and therapy of prostate cancer.
Effects of antiplatelet components of tomato extract on
platelet function in vitro and ex vivo: a time-course cannulation study in
healthy humans 1,2,3
American Journal of Clinical Nutrition, Vol. 84, No. 3, 570-579, September
2006
Natural antithrombotic agents that influence platelet function are of potential
interest for primary prevention of cardiovascular disease. Previous reports
showed that tomato extracts. The objectives of the study were to examine the
antiplatelet activity of specific tomato components by in vitro experimentation
and to establish their ex vivo efficacy in healthy humans. The mechanisms of
action of antiplatelet components isolated from tomato extracts were examined in
vitro. A 7-h time-course study was carried out in cannulated human subjects (n =
23) to determine the ex vivo efficacy of a supplement drink containing tomato
extract and the onset and duration of antiplatelet effects. Results: The
inhibition of ADP-, collagen-, thrombin-, and arachidonate-mediated platelet
aggregation by tomato extract components appears to be linked to the inhibition
of glycoprotein IIb/IIIa and platelet secretory mechanisms. We found a
significant inhibition of baseline platelet function after supplementation with
a dose of tomato extract equivalent to 6 tomatoes. The observed effects
persisted for >12 h. Coagulation variables were not affected. Conclusions: The
ingestion of tomato components with in vitro antiplatelet activity significantly
affects ex vivo platelet function. The reported cardioprotective effects of
tomatoes are potentially linked to a modulation of platelet function.
