"Tea and coffee drinkers have a lower risk of developing type 2 diabetes. And the protection may not be down to caffeine since decaf coffee has the greatest effect, say researchers," reports the BBC. " Analysis revealed that people who drink three or four cups of coffee or tea a day cut their risk by a fifth or more, say researchers. The same amount of decaffeinated coffee had an even bigger effect, lowering risk by a third. Type 2 diabetes usually starts after the age of 40 and develops when the body can still make some insulin, but not enough, or when the insulin that is produced does not work properly. Type 2 diabetes is treated with a healthy diet and increased physical activity. In addition to this, medication and/or insulin is often required."
