About

Epidemiological studies have indicated a positive health impact of coffee. Nevertheless, intervention studies testing the effect of daily coffee consumption over a longer period are lacking so far. Moreover, there is a lack of knowledge about the properties of different coffees and their influence on weight development. Therefore, we tested the effect of two coffees differing in their alkyl pyridine content over a period of 3 months on weight development.

Full description

Participants were randomly associated to two groups, a test coffee group and a control coffee group. After coffee abstinence of 1 months, participants in both groups got a coffee machine and coffee pads for three months. Clinical data have been assessed before and after coffee abstinence and after 3 months of coffee consumption.
