Tomatoes



Tomato, rich in antioxidants (抗氧化劑)and lycopene(番茄紅素), can remove free radicals(自由基).
Regular consumption of tomatoes can reduce the risk of lung cancer, gastric cancer, bladder cancer, uterine cancer, skin cancer, prostate cancer risk

In 2002 March 6, Journal of the National Cancer Institute, Men who consumed two-plus servings of tomato sauce per week had a 23% lower risk of total prostate cancer, and a 36% lower risk of metastatic prostate than participants who consumed less than one serving of tomato sauce per month. . Tomatoes contain abundant lycopene, which is a kind of carotenoids(類番茄紅素) that can used as antiocidants. And carotenoids also are the chemical substance to turn tomatoes, watermelon, and grapefruit into red heart.

Because human body cannot produce lycopene itself, human have to intake lycopene from foods. In addition, for both men and women, lycopene would be lower with increasing age.

In fact, almonds, guava, watermelon, papaya, red meat has a considerable content of grapefruit lycopene too, but tomato is still the best source. All forms of tomato (raw, in ketchup, spaghetti sauce, tomato paste, soup, and salsa) had beneficial effect; however, tomatoes cooked in oil (such as in tomato sauce) appeared to be the most protective. But the burgers and fries with the tomato sauce is not enough, so there’s no use to eat a lot burgers and French fries.
Most people think that fresh fruits and vegetables would be better to provide people healthy substance. However, according to studies, the lycopene in cooked tomatoes would help people more.

NTU Hospital Urology physicians said that raw tomatoes or drinking tomato juice would not be more effective than eating cooked tomato products. Therefore, if you want to absorb vitamin C, eat fresh tomatoes or drink tomato juice is good. But if you want to absorb the lycopene, tomato sauce added in the cooked vegetables or the fried tomatoes would be a better choice. For example, cooked tomato with scrambled eggs is a good example.
