To the Editor: In their Review article, Drs van Dam and Hu1 present evidence of the protective effect of coffee against development of type 2 diabetes. They speculate on possible mechanisms for this association, which include the antioxidant capacity of coffee and its role as a source of chlorogenic acid, quinides, caffeine, and magnesium. However, another phytochemical may also contribute to this effect.
