Health Effects of Coffee Consumption (DüsselKaffee)

December 28, 2012 updated by: Stephan Martin, West German Center of Diabetes and Health
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.

Detailed Description

Participants were randomly associated to two groups, a test coffee group and a control coffee group.
