Study suggests coffee can lower the risk of diabetes

Drinking more coffee may reduce the risk of developing the most common form of diabetes, a study has found.

Compared with non-coffee drinkers, men who drank more than six cups a day lowered their risk of type 2 diabetes by about half. Women drinking the same amount of caffeinated coffee reduced their risk nearly 30 per cent, says the study published in the Annals of Internal Medicine.

But experts said more research was needed to establish whether it really was the coffee, or something else about coffee drinkers that protected them.
