Can Coffee or Green Tea reduce the risk of Diabetes?

Diabetes is a disease in which the body does not produce or properly use insulin. Insulin is a hormone that is needed to convert sugar, starches and other food into energy needed for daily life. The cause of diabetes continues to be a mystery, although both genetics and environmental factors such as obesity and lack of exercise appear to play roles.

Coffee reduces risk of diabetes
Research suggests that people who drink coffee are less likely to get type 2 diabetes. It isn’t known whether the caffeine or some other ingredient in coffee is responsible for its protective effects.

The researchers wanted to see whether there is a link between diabetes and drinking coffee and green, black, and oolong tea. Participants completed a detailed questionnaire about their health, lifestyle habits, and how much coffee and tea they drank. The questionnaire was repeated at the end of the 5-year follow-up period.

When other factors were accounted for, researchers found that the more green tea and coffee participants drank, the less likely they were to get diabetes. People who drank six cups or more of green tea or three or more cups of coffee each day were about one-third less likely to get diabetes. The link was stronger in women than in men. No pattern was seen with black or long tea. (see Diabetes Symptoms)
