Caffeinated and decaffeinated coffee associated with lower risk of type 2 diabetes

Higher consumption of coffee is associated with lower risk of type 2 diabetes, according to research published in the February issue of Diabetes Care.

Consuming coffee has been shown to have beneficial effects on everything from weight gain to liver disease, including the prevention of hepatic fibrosis in chronic hepatitis C and NAFLD, as well as lowering the risk for hepatocellular carcinoma HCC.

A systematic review published in this months issue of Diabetes Care suggests caffeinated and decaffeinated coffee also reduced the risk of type 2 diabetes, a summary of data is provided by  HealthDay News, below.

MONDAY, Feb. 17, 2014 (HealthDay News) -- Higher consumption of coffee is associated with lower risk of type 2 diabetes, according to research published in the February issue of Diabetes Care.

Ming Ding, of the Harvard School of Public Health in Boston, and colleagues conducted a systematic review of the literature and performed a meta-analysis of 28 prospective cohort or nested case-control studies. The authors sought to assess the effect of coffee consumption on risk of type 2 diabetes.

The researchers found that, compared with no coffee or rare consumption of coffee, the relative risk (RR) for type 2 diabetes was 0.92 (95 percent confidence interval [CI], 0.90 to 0.94) for one cup per day; 0.85 (95 percent CI, 0.82 to 0.88) for two cups per day; 0.79 (95 percent CI, 0.75 to 0.83) for three cups per day; 0.75 (95 percent CI, 0.71 to 0.80) for four cups per day; 0.71 (95 percent CI, 0.65 to 0.76) for five cups per day; and 0.67 (95 percent CI, 0.61 to 0.74) for six cups per day.

No significant difference was found between the reduced risk of diabetes associated with a one cup per day increase for caffeinated coffee (RR, 0.91; 95 percent CI, 0.89 to 0.94) versus decaffeinated coffee (RR, 0.94; 95 percent CI, 0.91 to 0.98) (P for difference = 0.17).

"Coffee consumption was inversely associated with the risk of type 2 diabetes in a dose-response manner," the authors write. "Both caffeinated and decaffeinated coffee was associated with reduced diabetes risk."
