Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The overall aim is to investigate the intake of beta-glucan in relation to glucose metabolism and satiety in a postprandial study with healthy subjects. The potential effects will be related to changes in the gut microbiota, the circulating levels of short chain fatty acids, inflammation and gene expression in peripheral mononuclear blood cells

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The intervention study will have a fixed order, cross-over design with three test meals containing low (0.5 g / 100 g of product), medium (3.5 g / 100 g of product) and high (8 g / 100 g product) amount of beta -glucans, respectively. The test meals are in the form of cereals. All participants will eat the three test meals three constitutive days with 2 weeks apart. At day four, the participants will perform a postprandial glucose test (OGTT, 75 g glucose in 150 ml water) at Oslo and Akershus University College. Blood samples will be taken before and at different time points after glucose test.

At the screening visit the participants will be asked to limit the intake of dietary fiber from grains two weeks prior to the baseline visit (0) and during the study. Otherwise, participants will be asked not to change their diet and exercise habits during the study period.

At the baseline visit (visit 0) an OGTT will be performed. OGTT will also be performed at visit 1, 3 and 5 after intake of low, medium and high beta-glucan, respectively.

The participants will receive the test meals at visit 1, 2 and 4.
