Recent Studies Show Limited Association of Fruit and Vegetable Consumption and Cancer Risk

The message from the most thorough examinations to date of the benefits of diets high in fruits and vegetables is that higher consumption of fruits and vegetables decreases the risk of heart disease, but the benefit to cancer risk is less clear.
"But that's not to say there's absolutely no benefit for fruits and vegetables," said Walter Willett, M.D., Dr.P.H., who studies diet and cancer at the Harvard School of Public Health in Boston. He cited recent studies that have found an association between lycopene from tomatoes and reduced prostate cancer risk. "So if you get down to much more detail, there may be some things going on. But if you just stand back and look broadly at [eating five servings of fruits and vegetables each day], it's probably not going to have much benefit."
