Dietary Fibre and Metabolic Benefits

The purpose with this project is to study the association between bacterial fermentation in the colon of specific mixtures of cereal dietary fiber and effects on systemic metabolism and appetite regulation. For this purpose, short term studies are performed in healthy adult subjects. Different cereals, cereal blends and from cereal extracted dietary fiber will be studied, as well as effects of different processing of the cereals. Cardiometabolic test markers and colonic fermentation metabolites will be followed up to 14 h after intake of the test substrates, and gut microbiota composition will be determined prior to and after the interventions.
