I love coffee. Strong, black, rich-tasting coffee. But my enjoyment has been tempered in recent years by speculation that coffee (and its caffeine content) may reduce insulin sensitivity and lead to metabolic disorders such as diabetes.
However, a new meta-study looked at all the available information to assess the risk of type-II diabetes in habitual coffee drinkers.
The review consisted of a search in MEDLINE through January 2005 and examined the reference lists of studies that focused on habitual coffee consumption and risk of type 2 diabetes. Nine studies involving 192,473 participants met the criteria and were included in the review. Studies of Type 1 diabetes, animal studies, and studies of short-term exposure to coffee or caffeine were not included in the review.
The relative risk of type 2 diabetes was lowest in those who had the highest coffee consumption (6 to 7 cups per day) compared to those in the lowest consumption group (0 to 2 cups per day. The association did not differ substantially by gender, obesity, or region (United States and Europe). The results are consistent with cross-sectional studies conducted in northern Europe, southern Europe, and Japan. Higher coffee consumption was consistently associated with a lower prevalence of newly detected hyperglycemia, particularly post-prandial (following a meal) hyperglycemia.
The results of this review suggest that habitual coffee consumption is associated with a substantially lower risk of type 2 diabetes.
