Pereira and colleagues1 found that coffee consumption, especially decaffeinated, was independently associated with lower risk of type 2 diabetes mellitus after adjusting many confounders in postmenopausal women.1 In Table 3 of their article, there were 104 cases of type 2 diabetes mellitus among heavy coffee drinkers (ie, total coffee ≥6 cups per day). The number of cases declined further when decaffeinated coffee was analyzed separately.1 Considering the large number of study participants (n = 28 812) during the 11 years of follow-up,1 the absolute contribution of coffee intake to the risk of type 2 diabetes mellitus could be minimum. Therefore, at this point, encouraging coffee intake might not become a very popular recommendation. However, their study is a big step in exploring the potential benefit of coffee consumption in reducing the risk of type 2 diabetes mellitus, an epidemic disease.
