Original Khojo Papers practice question — not from a past board paper.
Answer
Roughage is the indigestible plant fibre, largely cellulose, in the diet. Whole grains and green vegetables and fruits are good sources. It supplies no nutrient but adds bulk to the food, holds water and stimulates the muscular movement of the intestine, so it prevents constipation.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
A diet low in roughage is associated with several disorders of the bowel.
