People with type 1 diabetes lose an average of 12 years of life because of their disease. But tight control of blood-sugar levels may reduce that loss. Those are the conclusions of 2 new studies. People with type 1 diabetes have to inject insulin because their bodies don't make it. The first study looked at nearly 25,000 adults with type 1 diabetes. Men died 11 years earlier and women 13 years earlier than people in a comparison group without the disease./Health Day People who eat more whole grains may live longer, a large new study finds.
