People who increased their consumption of red meat during a four-year period were more likely to develop Type 2 diabetes in a subsequent four-year period, according to an analysis involving about 150,000 people.
据一项涉及约15万人的分析显示，四年时间内增加红肉摄入量的人在随后四年内更有可能罹患II型糖尿病。
The analysis, led by researchers at the National University of Singapore, took data from three long-running Harvard University studies involving mostly nurses and doctors. The results were published online Monday in JAMA Internal Medicine, a journal of the American Medical Association. The studies were funded by grants from the National Institutes of Health.
该分析由新加坡国立大学(National University of Singapore)的研究员带头进行，从哈佛大学(Harvard University)三项主要涉及护士和医生的长期研究中获取数据。研究结果于6月17日发表在美国医学会(American Medical Association)旗下的《美国医学会杂志•内科学》(JAMA Internal Medicine) 网站上。这些研究由来自美国国立卫生研究院(National Institutes of Health)的津贴资助。
While prior studies have also found a link between red-meat consumption and the development of Type 2 diabetes, the new analysis is believed to be the first time researchers have tracked changes in red-meat consumption over time with the risk of developing Type 2 diabetes. Study participants filled out detailed questionnaires about the types of food and drinks they consumed at the beginning of the study and every four years. The analysis looked at some 20 years of data.
虽然以往的研究也发现红肉摄入与II型糖尿病存在联系，但这项新研究被认为是研究员首次追踪到长时间内红肉摄入的变化与罹患II型糖尿病风险的关系。参与研究者在研究开始时详细填写了有关自己所摄入饮食类型的调查问卷，随后每四年接受一次调查问卷。该分析研究了约20年的数据。
Broadly, the study showed that, compared with a group of people who had no change in red-meat intake, increasing red-meat consumption by more than a half-serving per day over a four-year period was associated with a 48% increase in the risk of developing Type 2 diabetes during the next four years.
总的来说，研究表明，四年内红肉日摄入量每增加半份，随后四年罹患II型糖尿病的风险就会比红肉摄入量无变化的人 高出48%。
However, reducing red-meat consumption by the same amount during the same time period didn't cut the risk of diabetes during the next four years. It did reduce the risk by 14% over a longer time period, though.
不过，同期内减少相同红肉摄入量者随后四年罹患II型糖尿病的风险并未下降，但更长时间内减少红肉摄入量令患病风险减少了14%。
The changes were independent of other factors such as body weight and overall diet quality.
这些变化排除了体重和整体饮食质量等其他因素的影响。
'Our results confirm the robustness of the association between red meat and [Type 2 diabetes prevention] and add further evidence that limiting red-meat consumption over time confers benefits for…prevention,' the study authors wrote. An Pan, an assistant professor at the National University of Singapore's Saw Swee Hock School of Public Health, was the study's lead author.
研究报告的作者写道：“我们的研究结果证实了红肉摄入与?II型糖尿病预防?之间的稳固联系，并进一步证明长期限制红肉摄入有助于预防该疾病。”新加坡国立大学苏瑞福公共卫生学院(Saw Swee Hock School of Public Health)助理教授An Pan是该项研究的首席作者。
Other doctors say red meat in and of itself isn't necessarily the trouble.
有医生表示红肉本身并不一定是问题所在。
'It is not the type of protein (or meat) that is the problem; it is the type of fat,' said William J. Evans, who is affiliated with both Duke University and GlaxoSmithKline PLC., and who wrote a commentary about the study that was also published online in JAMA Internal Medicine. 'It's mischaracterizing red meat as high fat,' Dr. Evans said in an interview.
隶属杜克大学(Duke University)及GlaxoSmithKline PLC.医药公司的威廉•埃文斯(William J. Evans)针对这项研究撰写了一份评论，也发表于《美国医学会杂志•内科学》网站上。他说：“问题并不在于蛋白质（或肉类）类型，而是脂肪类型。”埃文斯博士在采访中说：“研究把红肉曲解成了高脂肪。”
He said consumers could choose lean cuts of red meat such as sirloin tips or round steak over high-fat cuts like rib-eye.
他说，消费者可以选择比较瘦的红肉，比如牛里脊肉或腹腿牛排，而不要选择肋眼牛排这样的高脂肪部位。
Dr. Pan could not be reached for comment Monday.
记者未能联系到An Pan博士对此置评。
Similar to general dietary guidelines from the U.S. government, the American Diabetes Association recommends people with diabetes eat lots of vegetables and fruit and choose whole-grain foods including dried beans, as well as eating fish two or three times a week. Lean meats include cuts of beef or pork that end in 'loin,' such as pork loin and sirloin.
与美国政府的通用饮食指南相似，美国糖尿病协会(American Diabetes Association)建议糖尿病患者大量摄入蔬菜和水果，选择包括干制豆类在内的全谷类食品，每周食用两次或三次鱼类。瘦肉包括以“里脊”结尾的牛肉或猪肉，比如猪里脊肉和牛里脊肉。
Diabetes affects about 26 million Americans and is characterized by high blood-glucose levels caused by the body's inability to either make or properly use insulin. Type 2 diabetes, the most common form of the disease, is often associated with weight gain and older age. The disease raises the risk of heart attacks and strokes, kidney disease, blindness, amputations and nerve damage. The other type of diabetes, Type 1, is an autoimmune disease and often diagnosed in childhood.
美国约2,600万人患糖尿病，主要表现为身体无法产生或正常使用胰岛素而造成的高血糖。II型糖尿病是最普遍的糖尿病类型，通常与体重增加和年龄增加有关。这种疾病会增加心脏病发作和中风、肾脏疾病、失明、截肢及神经损伤的风险。另一种是I型糖尿病，是一种自身免疫疾病，通常在孩童时期得到确诊。
The Centers for Disease Control and Prevention has projected that as many as 1 in 3 U.S. adults could have diabetes by 2050. The disease is currently the seventh leading cause of death in the U.S.
美国疾病控制与预防中心(Centers for Disease Control and Prevention，简称CDC)预测到2050年，高达三分之一的成年美国人都会患糖尿病。目前糖尿病是美国人第七大死因。
Doctors say that improving diet is important not only for managing diabetes, but for keeping the adult-onset Type 2 at bay for those with the highest risk. The CDC estimates that 35% of U.S. adults age 20 and older─nearly 80 million Americans, by the agency's estimate─are affected with prediabetes, a condition in which people have higher-than-normal blood-glucose levels. People with prediabetes also have a higher risk of developing problems like heart disease and stroke.
医生们表示，改善饮食不仅对控制糖尿病至关重要，而且可以预防风险最高的成年人群的患病。CDC估计35%的20岁及以上的美国人──据估计相当于近8,000万人──处于糖尿病前期状态，即血糖水平高于正常值。糖尿病前期病人出现心脏病和中风等问题的风险也较高。
Researchers said one of the limitations of the study was that participants were mostly white, educated U.S. adults. Some groups have a higher risk than others for developing Type 2 diabetes, according to the diabetes association, including African-Americans and Hispanics.
研究人员说，该项研究的一个局限是大多数参与研究者都是受过教育的美国白人。据美国糖尿病协会称，有些人群罹患II型糖尿病的风险比较高，包括非洲裔和西班牙裔美国人。
The diabetes and red-meat analysis involved data from the Health Professionals Follow-Up Study collected between 1986 and 2006, as well as information from two groups of women in the Nurses' Health studies collected during a similar time period
这项针对糖尿病和红肉摄入的研究分析了来自从医人员跟进研究(Health Professionals Follow-Up Study)1986年至2006年间的数据，以及护士健康研究项目(Nurses' Health Study)在同一个时期内收集于两组女性参与者的信息。
