About

The consumption of oat bran fiber also has a significant bulking effect in humans. However, besides fecal bulk, dietary fiber can promote gut health in other ways. Therefore, the purpose of this study is to investigate the effects of oat bran (rich in oat beta-glucan) supplementation on bowel function and appetite.

Full description

The study is a randomized, double-blind, placebo-controlled crossover study it involves a total of 8 visits with a 14 day run-in period for total study duration of 84 days. A washout period of 2 weeks will occur in between the 2, 28 day treatment periods. The effects of an oat bran beverage for breakfast on bowel function will be tested after 2 week and 4 weeks of intake.
