Coffee and tea can reduce type 2 diabetes: more evidence

Yet more research, this time a meta-analysis published in Archives of Internal Medicine that accepted data from 18 studies with information on 457,922 patients. They found that "every additional cup of coffee consumed in a day was associated with a 7% reduction in the excess risk of diabetes..." They go on to conclude: "Similar significant and inverse associations were observed with decaffeinated coffee and tea and risk of incident diabetes. High intakes of coffee, decaffeinated coffee, and tea are associated with reduced risk of diabetes." HOWEVER: those individuals who have a common Th2-type autoimmune disorder or severe sympathetic nervous system hyperarousal can be made worse from these beverages.
