《中英對照讀新聞》Dairy foods could help prevent diabetes 乳製食品可能有助預防糖尿病

◎國際新聞中心

A natural substance found in dairy products appears to protect against diabetes, say researchers. Trans-palmitoleic acid is present in milk, cheese, yoghurt and butter but cannot be made by the body. A study of over 3,700 people found higher levels of trans-palmitoleic acid was linked with a reduced risk of type 2 diabetes. People with the highest levels cut their risk by 60％.

研究人員說，乳製品中的天然物質似乎可預防糖尿病。反式棕櫚烯酸在牛奶、起司、優格與奶油中找得到，但無法透過身體製造。針對3700人的研究發現，反式棕櫚烯酸較多，與第2型糖尿病風險較低相關。反式棕櫚烯酸最高者，風險降低60％。

Lead author of the research, Dr Dariush Mozaffarian, said： "The magnitude of this association is striking. "This represents an almost three-fold difference in risk of developing diabetes among individuals with the highest blood levels of this fatty acid."

研究首席作者莫札法林恩博士說：「相關性高達這種程度令人震驚。」「這代表擁有此種脂肪酸最高血液濃度者，糖尿病發作風險將近3倍的差異。」

Deepa Khatri, clinical advisor at Diabetes UK, said： "Milk and dairy foods can be high in fat, which if eaten in excess can contribute to weight gain. So it’s advisable to choose lower-fat dairy foods instead."

英國糖尿病臨床顧問卡特里說：「牛乳與乳製食品可能含高脂肪，如果食用過量可能導致體重增加，所以建議改選較低脂乳製品。」

Experts say more research is needed to see whether these trans-palmitoleic acids can play a useful role in preventing Type 2 diabetes. In the meantime, they recommend that all people, with or without diabetes, should have a healthy balanced diet, low in fat, salt and sugar with plenty of fruit and vegetables.

專家說，還需要較多研究，觀察反式棕櫚烯酸是否在預防第2型糖尿病扮演實用角色。同時他們也建議，不論是否有糖尿病，所有人都應該飲食健康均衡、低脂、低鹽、低糖、多吃蔬果。
