简要总结
The aim of the study is to better understand the interplay between the intake of dietary fiber and intestinal bacteria, their metabolic activity and the effect on the intestinal barrier.
The effect of two different dietary fiber supplements is tested (arabinoxylan & ß-glucan versus inulin & fructooligosaccharides) in a randomized crossover intervention trial including healthy volunteers.
