In this study consumption of fruits and vegetables was associated with
reduced risk of various types of cancer, including cancer of the colon or
rectum as in the study mentioned by Brian in which fiber was named as the
reason for the reduced risk.

We compared the effect of 26 types or groups of vegetables and fruit on the
risk of cancer using data from two case-control studies that included 1,225
cases of cancer of the colon, 728 cases of cancer of the rectum, 2,569 cases
of cancer of the breast, and 5,155 hospital controls interviewed between
1991 and 1996 in six Italian areas. Most vegetables were inversely
associated with cancer of the colon and rectum, whereas only carrots and raw
vegetables lowered breast cancer risk. High fruit intake was associated only
with a reduction of rectal cancer. Different contents of sugar, fiber,
carotenoids, and folic acid in fruits vs vegetables plus the concurrent
consumption of oil with vegetables may partly explain these findings.
