title: [Free-radical theory and the antisenescence effect of fruits and vegetables].
abstract: Oxidative damage resulting from free radical is a major cause of ageing and chronic degenerative disease. Epidemiological studies show that frequent consumption of fruit and yellow or green leafy vegetables may prevent many kinds of chronic degenerative diseases associated with the increasing of age. These may be related with the anti-oxidative ingredients in fruit and vegetables. Nevertheless, trials using anti-oxidative nutrient, such as vitamin C, E and beta-carotene supplements, did not get the expected result so far. Thus, it is necessary to strengthen the research on the potential effective anti-oxidative ingredients in fruit and vegetables. On the other hand, the study on the effect of fruit and vegetables on life span and improving life quality are also needed.
