October 9, 2008 — Regular consumption of coffee and potentially black tea, but not green tea, is associated with a lower risk for type 2 diabetes mellitus in Singaporean Chinese men and women, according to the results of a study reported in the October issue of the American Journal of Clinical Nutrition.
"Increasing coffee intake was inversely associated with risk of type 2 diabetes in populations of European descent; however, data from high-risk Asian populations are lacking as are data on tea intake in general," wrote Andrew O. Odegaard, from the University of Minnesota in Minneapolis, and colleagues. "We investigated the prospective associations between intakes of coffee, black tea, and green tea with the risk of type 2 diabetes in Singaporean Chinese men and women."
