About

This study examines how various non-alcoholic beverages affect blood sugar levels.

The beverages are a non-alcoholic, fiber-enriched beer, a conventional non-alcoholic beer, and a sugar solution. Participants drink one of these beverages on different days. Afterwards, a sensor on the upper arm is used to measure the sugar content in the body fluid under the skin over a period of two hours.

The aim is to find out how much blood sugar concentration rises after drinking. This will be used to check whether the non-alcoholic, fiber-enriched beer has a more favorable effect on sugar metabolism than conventional beverages. Participation is voluntary, and the data will be treated confidentially.
