The association between high intake of fruit and vegetables and low incidence of certain cancers is well established....  These findings strongly support the hypothesis that fruit and vegetables exert a cancer-protective effect via a decrease in oxidative damage to DNA.”

“Chlorophyllin, a derivative of the green plant pigment chlorophyll, was found to be a potent inhibitor of hepatocarcinogenesis...  Because of the abundance of chlorophyll in the human diet, it is suggested that this compound might be an important contributing  factor to the observed cancer preventive activities associated with a  high intake of vegetables and fruits.” ,

Epidemiologic studies have provided circumstantial evidence for cancer prevention by dietary vegetables and fruits.... Numerous factors could influence these results. Several studies have demonstrated potential antimutagenic properties of vegetables and fruit extracts.

Vegetables and fruits contain certain compounds which can be converted to biologically active hormone-like substances, such as lignans and isoflavones, by intestinal flora. The interaction of these compounds with endogenous hormones may be a novel, diet-dependent mechanism in cancer prevention.

We conducted a population-based study of diet and lung cancer among the multiethnic population of Hawaii in 1983-1985....  This  observation suggests that other constituents of vegetables, such as lutein, lycopene, and indoles, and others, may also protect against lung cancer in humans.r

The main source of dietary antioxidants is fruits and vegetables. Insufficient fruit and vegetables consumption increases the rate of most types of cancer about two fold as shown by about 200 epidemiological studies that are  remarkably consistent.

Epidemiological studies have shown that diets  containing large quantities of vegetables and, to a lesser extent,  fruits are associated with relatively low risks from cancer... As studies of the inhibitory  capacities of dietary non-nutrients continue, a clearer picture of their potential impact in cancer prevention is emerging.

"The lower risk of cancer observed in these studies among people who eat more carotenoid-rich fruits and vegetables (and who consequently have higher blood levels of carotenoids) could be due to substances other  than carotenoids in these foods,.. For now, the most rational and prudent choice would be  to consume a diet high in fruits and vegetables"

“It is conceivable that the decrease in mortality risk associated with higher initial plasma beta carotene concentrations in our study was actually a manifestation of the conjoint beneficial effects of a number of factors related to diet. If so, programs to change dietary patterns toward consumption of more vegetables, fruits, and grains may prove  more effective than altering intake of individual micronutrients such as beta carotene.”
