Fibers (dietary fiber, more rarely non-nutritive carbohydrates) are largely indigestible dietary constituents, mostly carbohydrates, which occur predominantly in plant foods. They are found mainly in cereals, fruits, vegetables, legumes and in small quantities in milk. For the sake of simplicity, one divides the fiber into water-soluble (such as locust bean gum, guar, pectin and dextrin’s) and water-insoluble (for example, cellulose). Dietary fiber is now, quite differently than the name suggests, as an important part of the human diet. The EU Nutrition Labelling Regulation gives them a gross calorific value of 2kcal /g.
