57. Diet: Consume Fruits and Vegetables
In contrast to factors such as fat and calories, which appear to increase cancer risk, other dietary components may decrease cancer risk. The most compelling evidence has been obtained for fruits and vegetables, whose consumption has been strongly correlated with a reduction in cancer risk. Although the exact chemical components in these foods that are responsible for a protective effect are yet to be identified, eating five to nine servings of fruits and vegetables each day is recommended by many groups.
