怎样有效预防糖尿病?

　　In the United States alone,more than 20 million people have diabetes. That’s according to Paul Robertson, president of Medicine & Science at the American Diabetes Association.

　　据美国糖尿病协会医学科学主席保罗·罗伯逊说，仅在美国就有超过2000 万人患有糖尿病。

　　Paul Robertson: With all diabetes, the diagnosis is made because blood glucose, or blood sugar levels, rises above normal. He said that diabetes is so devastating because it’s a progressive illness that does lots of organ damage, and the disease gets worse with time.

　　保罗·罗伯逊：对所有糖尿病病例来说，我们都以血液中的葡萄糖水平——即所谓的血糖——高于标准作为确诊依据。他说， 糖尿病非常具有破坏性，因为这种逐步恶化的疾病会造成许多器官损伤，症状也会随时间加重。

　　Robertson: The longer that the blood glucose levels stays elevated, the more damage it does to very important tissues in the body. And actually it damages the pancreas itself, after a while.

　　罗伯逊：血糖水平过高的时间越长，它对身体非常重要的器官造成的伤害就越大。事实上，一段时间之后它对胰腺本身也会产生伤害。
