Non-alcoholic, fiber-enriched beer and its effect on blood sugar levels: A scientific study
Summary description of the study
This study investigates how different non-alcoholic beverages affect blood sugar levels. The beverages include a non-alcoholic, fiber-enriched beer, a regular non-alcoholic beer, and a sugar solution. Participants drink one of these beverages on different days. Afterwards, a sensor on the upper arm measures the sugar content in the body fluid under the skin over two hours. The goal is to find out how much the blood sugar level rises after drinking. This will help determine whether the new beer has a more favorable impact on sugar metabolism compared to conventional beverages. Participation is voluntary, and the data will be treated confidentially.

Intervention under investigation
The study investigates a non-alcoholic, fiber-enriched beer (FEB) that has an increased fiber content which could positively affect blood sugar levels. The intervention consists of consuming this FEB compared to a commercially available non-alcoholic reference beer (Störtebecker Alkoholfrei) and a glucose solution. The goal is to compare the blood sugar response (iAUC) to the respective beverages.

Disease under investigation
This study does not investigate a specific disease. The aim is to examine the blood sugar response of healthy adults to various beverages (non-alcoholic, fiber-enriched beer, non-alcoholic reference beer, glucose solution) to evaluate postprandial glucose regulation.
