Colorectal Cancer

Risk Factors

Diet

Population studies suggest that diets high in fat (especially animal fat) and low in calcium, folate, and fiber may increase the risk of colorectal cancer. Also, some studies suggest that people who eat a diet very low in fruits and vegetables may have a higher risk of colorectal cancer. However, more research is needed to better understand how diet affects the risk of colorectal cancer. The link between diet and colorectal cancer is not firmly established.
