What is soluble fibre?
A. Soluble fibre dissolves and thickens in water. Soluble fibre is probably best known for its cholesterol-lowering effect. Soluble fibre is made up of sticky substances like gums and pectin, which form a gel-like substance in the presence of liquid. Cholesterol that is stored in the blood is used to produce bile acids; and therefore, as the gel binds the cholesterol and bile acids in the small intestine, it is eliminated from our body with regular bowel movements. This action of gelling and binding is also responsible for soluble fibre’s ability to promote a feeling of fullness. In contrast, insoluble fibre is the roughage in our diet that helps promote a healthy digestive system.
