Colorectal cancer is a cancer that begins in the colon or rectum, and it is one of the leading causes of cancer-related death in the United States. According to the American Cancer Society (ACS), around 95,520 new cases of colon cancer and 39,910 cases of rectal cancer will be diagnosed in the U.S. this year, and more than 50,000 people are expected to die from the disease. A wealth of research has suggested that a diet rich in fiber and whole grains may protect against the development of colorectal cancer.
