Rani avoids eating fruits and vegetables but likes to eat biscuits, noodles and white bread. she frequently complains of stomach ache and constipation What are the food items that she should include in her diet to get rid of this problem? Give reasons for your answer.

Answer»

Rani should start eating foods rich in dietary fiber to get rid of this problem.

  • Dietary fiber or ROUGHAGE makes the feces BULKY by increasing its weight and size making it easier to pass, thus RELIEVING constipation.  .

  • Roughage is found in whole grains, fruits, vegetables, legumes, etc.
  • It has many health benefits, so it is included in the diet for the management of diabetes, heart DISEASES, improper bowel movements, etc.  and weight loss programs.
  • In addition, Rani should avoid eating unhealthy foods to stay healthy.
