Moderate coffee consumption is associated with a reduced risk of having diabetes, according to researchers in Greece.

The findings come from a study of 500 men and 437 women (aged 65-100 years) from Cyprus, Crete, and other Mediterranean islands. Of the 937 subjects, 84% of them reported drinking coffee.

All were asked about the frequency of any type of coffee consumption throughout the past year. Most participants drank boiled coffee. Subjects reported drinking coffee for at least 30 years of their life.

Compared with those who did not drink coffee, those who drank one to two cups a day had a 53% lower risk of having diabetes, after adjusting for potential confounders, investigators report in The Review of Diabetic Studies (2007;4:105-111). Diabetes prevalence was not associated with greater coffee consumption. The association of coffee drinking with diabetes was significant only among non-tea drinkers, the authors state.
