Importance of Dietary Fibre

Dietary Fibre is an essential nutrient required for proper digestion of foods, proper functioning of the digestive tract and helping you give the Satiety.

Senior Nutritionist Khushbu Shah briefs the importance of dietary fibre, its types, and its importance in our diet.


There are 2 major types of Fibre


  1. Soluble Fibre

  2. Insoluble Fibre





Role of Fibre in the Digestive Tract:

  • Dietary fibre mixes with partially digested food in the stomach

  • In the small intestine, Soluble Fibre entraps Sugar, Cholesterol and Fats slowing their absorption in the body.

  • Hydration of the Fibre i.e. it mixes with water and forms gel-like substance that increases the viscosity of food mass giving the feeling of fullness which actually increases the Satiety value in the stomach.

  • In the Large Intestine, the Polysaccharide Fibre gets metabolized by the bacteria and creates Short-chain Fatty acids.

  • Thus Aids in Bulking of the food which promotes the regularity of Bowel Movement.


Benefits of High Fibre Diet:

  • Normalizes Bowel Movement: Dietary Fibre increases the weight and Size of the Stool and softens it. A bulky stool is easier to pass decreasing the chances of Constipation.

  • Helps in Curing Diarrhoea: In case of Diarrhoea, Fibre helps in solidifying the stool as the Soluble Fibre will absorb water and add bulk to the stool.

  • Helps Maintain Bowel Health: A high Fibre Diet may lower the risk of developing Haemorrhoids and Diverticulitis. Studies have proved that it also helps to lower the risk of Colon Cancer.

  • Lowers Cholesterol: Soluble fibre lowers cholesterol by binding to it in the small intestine. Once inside the small intestine, the fibre attaches to the cholesterol particles, preventing them from entering into the bloodstream and travelling to other parts of the body. Instead, cholesterol will exit the body through the faeces.

  • Helps Control Blood Sugar: In people with diabetes, fibre — particularly soluble fibre — can slow the absorption of sugar and help improve blood sugar levels. A healthy diet that includes insoluble fibre may also reduce the risk of developing type 2 diabetes.

  • Maintenance of weight: Consumption of High Fibre foods tends to give more Feeling of fullness i.e. higher Satiety Value than low fibre foods, thus making the person eat less and stay satisfied longer. And high-fibre foods tend to take longer to eat and to be less "energy-dense," which means they have fewer calories for the same volume of food.
