Protective effect of dietary fibers against colorectal carcinoma.

Dietary fibers are remnant of plant cells resistant to hydrolysis by human alimentary tract enzymes. These are cellulose, hemicellulose, lignin, pectins and gums. Intake of dietary fibers or foods rich in dietary fibers decreases the incidence of colorectal carcinoma. Reduced risk of colorectal carcinoma is reported when populations with diet high in red meat and total fats switched to a diet high in total fibers and certain whole grain, goods. Fibre intake is also inversely related to mortality from colorectal carcinoma. Beneficial influence of most vegetables and fruits against colorectal carcinoma is confirmed and this is due to their fibre contents.
