Diet: Limit Fats and Calories

Studies suggest that differences in diet may also play a role in determining cancer risk. But in contrast to the clear-cut identification of tobacco, sunlight, and alcohol, the exact identity of the dietary components that influence cancer risk has been difficult to determine. Limiting fat consumption and calorie intake appears to be one possible strategy to decrease risk of some cancers, because people who consume large amounts of meat (which is rich in fat) and large numbers of calories exhibit an increased cancer risk, especially for colon cancer.
