5. Study Description

Brief Summary
The aim of the present study is to determine the effect of non-nutritive sweeteners on intestinal barrier function and inflammatory markers in healthy subjects in comparison to mono- and disaccharides.
Detailed Description
In the intervention study normal weight participants will receive beverages sweetened with non-nutritive sweeteners, mono- and disaccharides for a defined number of days. Before and after intervention parameters of intestinal barrier function will be assessed.
