Fiber

undefined: Fiber is a non-absorbable part of food, usually of plant origin.

It is divided into soluble, fibre, which can be partially utilised by intestinal bacteria, and non-soluble, fibre, which passes through the digestive tract unchanged.

Chemically, they are mostly polysaccharides, such as cellulose, hemicelluloses, lignin, pectin, agar or inulin.
