It appears that antioxidants in coffee, and not the caffeine, reduced women's risk of developing diabetes, according to an 11-year study.
The study involved close to 29,000 older women who answered questions about their risk factors for diabetes and reported information about their dietary habits. Women who drank more than six cups of coffee a day were 22 percent less likely to develop type 2 diabetes than those who drank no caffeine.
However, among those who drank over six cups of decaffeinated coffee a day, the risk decreased by 33 percent.
The researchers pointed out that coffee is a rich source of antioxidant chemicals, and drinking four or more cups a day could lead to powerful antioxidant activity, even when no caffeine is involved.
For instance, coffee contains chlorogenic acid -- also present in red wine and chocolate -- which slows cells' absorption of sugar and animal studies have found to lower blood sugar levels.
