The Importance of High-Fiber Diets in Preventing Colon Cancer

Fiber is vital for a healthy digestive system. Dietary fiber provides nourishment for beneficial bacteria in the colon. Colon bacteria are beneficial because they produce vitamins and enzymes that help make digestion possible. The bacteria also enhance the immune system and help to control cholesterol. All the parts of the plants you eat that aren’t digested contain fiber, also called roughage and bulk. A healthy bacterial balance in the colon may help prevent some cancers. Dietary fiber is important to help keep colon bacteria healthy, which may reduce the risk of colon cancer.

Does eating a high fiber diet reduce the risk of colon cancer? There are studies that support the contention that it does reduce the risk of colon cancer, while other studies don’t indicate a significant benefit for reducing the risk of colon cancer. According to a study reported in the Journal of American Medical Association, titled Dietary Fiber Intake and Risk of Colorectal Cancer, researchers concluded that “high dietary fiber intake was not associated with a reduced risk of colorectal cancer.” The American Gastroenterological Association recommends eating foods that have a high roughage content as a preventative measure against colon cancer. In contrast, Methods May Affect Fiber-Cancer Link, Harvard Health Publications noted that people who reported eating an average of twenty-four grams of roughage daily were thirty percent less likely to develop colon cancer than people who ate ten grams or less. Harvard Men’s Health Watch reported in 2005 that men who consume between thirty and thirty-eight grams daily could reduce their risk of developing colon cancer by as much as fourty percent.

Let us continue with this blog post. A high fiber diet has many health benefits including some links to reduced risk of colon cancer. Dietary fiber may be insoluble or soluble. Insoluble fiber doesn’t dissolve in water, but moves through the digestive system and is primarily associated with regularity and relief of constipation. Raw vegetables, whole grains and wheat bran are excellent sources. Soluble fiber dissolves in water. It’s associated with reducing sugar and cholesterol. Food like oats, beans, carrots and peas can meet this dietary requirement. Fiber rich diets also help you to feel fuller so that you eat less. This effect can help reduce obesity which has been linked to some cancers.

A diet rich in roughage and bulk foods that don’t digest may help you reduce your risk of colon cancer. A healthy diet includes foods that will provide the necessary bulk to help your digestive system function normally.
