Fiber contributes to lowering the postprandial rise in blood glucose because it delays the absorption of carbohydrates from the meal that has been eaten.

What is fiber?

Fiber is made up of various polysaccharides called non-starch (non-glycemic) polysaccharides that are not digested by human digestive enzymes.

Characteristics of fiber

  • It prevents a sudden increase in blood glucose levels after meals.

  • It cannot be broken down into sugar molecules, so it passes through the body undigested, binds to fat in the intestine and drags it along, helping to regulate blood sugar.

Therefore, we can conclude that fiber decreases the absorption of food substances such as cholesterol and delays the absorption of glucose, lowering the glycemic index of foods.
