discuss the importance of roughage in our diet


Roughage consists of undigestible carbohydrates found in fruits and vegetables and remains undigested in the entire digestive tract from mouth to anus.

The roughage serves certain important functions:
  1. It helps the muscles of the digestive tract in the formation of stools.
  2. It prevents constipation and ensures proper bowel movement.
  3. A diet that supplies adequate roughage is thought to reduce the incidence of heart diseases, bowel cancers and irritation of the bowels.
