The so-called “insoluble fibre” includes cellulose, insoluble hemicellulose and lignin. They are mainly found in grains and legumes. Insoluble fibre is characterised by its high swelling capacity. In this way, they increase stool volume and stimulate intestinal activity.
Oats contain 11 g fibre / 100 g. These are made up of approximately 54 % insoluble fibre and 46 % soluble fibre. As part of the Health Claims Regulation, the statement “Oat grain fibre contributes to an increase in faecal bulk” is permitted.
