6、nting cancer is a compelling reason to lead up your cart in the produce department. Scientists have recently estimated that approximately 30 to 40 percent of all cancers could be averted if people ate more fruits, vegetables, and plant based foods and minimized high-fat, high-calorie edibles that ha
7、ve scant nutritional value. Up to 70 percent of cancers might be eliminated if people also stopped smoking, exercised regularly, and controlled their weight.In the past, researchers had linked fat consumption with the development of cancers, but they currently believe that eating fruits, vegetables,
8、 and grains may be more important in preventing the disease than not eating fat. The evidence a bout a high-fat diet and cancer seemed a lot stronger several years ago than it does now, says Melanie Polk, a registered dietitian and director of nutrition education at the American Institute for Cancer
9、 Research.Although scientists are still not certain about the specifics, theyre beginning to close in on the healthful constituents of plant-based foods. In particular, theyre looking closely at two componentsantioxidants and phytochemicals.Antioxidants. The antioxidants(carotenoids, such as beta ca
10、rotene and lycopene, and vitamins C and E) found in fruits, vegetables, and other plant-based foods fight free radicals, which are compounds in the body that attack and destroy cell membranes. The uncontrolled activity of free radicals is believed to cause many cancers.The carotenoids, in particular
11、, which give fruits and vegetables their bright yellow, orange, and red colors, are now gaining recognition for their nutritional worth. Numerous studies have extolled the virtues of lycopene(the carotenoid that makes tomatoes red) in preventing prostate cancer. One such study at Harvard University
12、found that men who include tomato products in their meals twice a week could reduce their risk of developing prostate cancer by one-third compared with men who never touch tomatoes.Other lycopene-rich foods, such as watermelon, red grapefruit, and guava, are now piquing the interest of researchers.
13、Watermelon not only yields more lycopene per serving(15 mg in 11/2 cups ) than raw tomatoes(11 mg per 11/2 cups), but its also a rich source of vitamins A and C.Can watermelon help reduce the incidence of cancer? No one knows for sure because there havent been sufficient studies. We assume that well
14、 see benefits, says Penelope Perkins-Veazie, Ph.D. a research scientist with the USDAs Agricultural Research Service. Researchers there plan to compare people who eat watermelon with those who eat processed tomatoes-because cooking enhances lycopene absorption-to see which group absorbs more lycopen
15、e.(A 11/2 cup serving of tomato sauce packs 53 mg of lycopene.)Phytochemicals. The phytochemicals present in fruits and vegetables protect the body by stunting the growth of malignant cells. Phytochemicals, naturally occurring substances, include indoles(生化吲哚) in cabbage or cauliflower, sapenins(生化皂

They are confident, however, that you can get a basketful of ant-cancer nutrients by mixing and matching at least five seA.Y B.N C.NG8.Using technology is an easy way to
