On World Health Day, a doctor emphasizes adding roughage (dietary fiber) to our meals. Why is roughage essential for health, even though it provides no energy or nutrients?
  1. It destroys bacteria present in the stomach
  2. It adds bulk to food and helps in smooth bowel movement
  3. It converts fats directly into proteins
  4. It dissolves toxic minerals in blood

Solution

Roughage consists mainly of indigestible cellulose which adds bulk to indigestible food waste, aiding smooth movement through the digestive system.
