I have to chime in with Brian. I eat a huge bowl of fruit every day, as one meal, and because I like it. Blueberries, blackberries, raspberries and strawberries and anything else in season, melons, peaches, kiwi, pears, papaya, mangos, etc. It makes me feel better - is it really "chemopreventive"? Who knows. My wife pointed out to me that (fresh) fruits and vegetables are the only food we eat that are actually "alive" when we consume them. In any case the fiber is good for you.

Keeping these fresh is a challenge. Luckily I work at home and the market is 5 minutes away so I shop for fruit at least 3-4 times a week. Even so, I have some VERY happy and well fed worms in my composter.

Gary -- sounds like you're on the right track:

NEW YORK (Reuters Health) - Men who consume high quantities of fruits, especially citrus fruits and juices, have a significantly lower risk of developing oral premalignant lesions, irregular tissue that has not yet developed into cancer, according to the findings published in the American Journal of Epidemiology. ...

Citrus fruits, citrus fruit juice, and vitamin C-rich fruits and vegetables were associated with a significantly lower risk of oral premalignant lesions. Greater quantities of these foods in the diet were linked to a 30- to 40-percent lower risk.

For example, the risk of oral premalignant lesions in subjects with the highest level of citrus fruit juice in the diet was 30 percent lower than those with the lowest level.

Overall, the researchers conclude that "dietary recommendations to increase consumption of fruits are appropriate for preventing oral precancer and cancer."
