JAMA (Journal of the American Medical Association) 2005;294:97-104.
ABSTRACT

Context Emerging epidemiological evidence suggests that higher coffee consumption may reduce the risk of type 2 diabetes.
Objective To examine the association between habitual coffee consumption and risk of type 2 diabetes and related outcomes.
Data Sources and Study Selection We searched MEDLINE through January 2005 and examined the reference lists of the retrieved articles. Because this review focuses on studies of habitual coffee consumption and risk of type 2 diabetes, we excluded studies of type 1 diabetes, animal studies, and studies of short-term exposure to coffee or caffeine, leaving 15 epidemiological studies (cohort or cross-sectional).
