High coffee consumption may reduce the risk of type 2 diabetes

A medical article by Rob M. van Dam, PhD and Frank B. Hu, MD, PhD in JAMA (Journal of the American Medical Association) suggests that higher coffee consumption may reduce the risk of type 2 diabetes.
The objective of the study was to “examine the association between habitualcoffee consumption and risk of type 2 diabetes and related outcomes:”

We searched MEDLINE through January 2005 and examined the reference lists of the retrieved articles. Because this review focuses on studies of habitualcoffee 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).
