To Prevent Diabetes, Have Another Cup Of Coffee

Seems like every day there's another study telling us that coffee is good for us. Or terrible. Well, here's one more to add to the mix.

Researchers from the Harvard School of Public Health have examined not just coffee's effects on health, but how changes in habits of coffee and tea drinking may affect health. Their recent study, published in the journal of Diabetologia last week, showed that increased coffee intake over a four-year period was linked to a decreased risk of having type 2 diabetes.

The study, which draws on longterm observational information from more than 120,000 health professionals for up to 20 years, found that those who had increased their coffee intake by more than one cup a day over a four-year period had an 11% lower risk of having type 2 diabetes. And increased intake wasn't the only consumption change that seemed linked to the disease. Participants who decreased their consumption by more than a cup a day were at a 17% greater risk of having type 2 diabetes.

These differences in risk, the study said, held true for coffee but not tea, caffeinated and not decaffeinated coffee, and seemed to exist regardless of initial coffee intake and other lifestyle changes occurring during the same four-year period.

Researchers also noted that a previous meta-analysis had found that for every additional cup of coffee consumed per day, risk of type 2 diabetes dropped by 7%.

Maybe we don't have to feel guilty about that post-lunch cup of coffee after all!
