discuss the importance of roughage in our diet

Solution:

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.
