2024考研英语同源外刊:阿斯巴甜可能致癌,意味着什么?
On Thursday, two World Health Organization agencies released their findings on aspartame, the artificial sweetener found in thousands of sugar-free products like diet sodas, chewing gums, yogurts and energy drinks.
周四，世界卫生组织的两个机构公布了他们对阿斯巴甜的研究结果，这是一种人工甜味剂，被用于成千上万的无糖产品中，如无糖汽水、口香糖、酸奶和能量饮料。
The organization’s International Agency for Research on Cancer classified aspartame as possibly carcinogenic to humans. A separate group, the Joint Expert Committee on Food Additives, said that there was not convincing evidence of a link between aspartame and cancer in humans and that people could still safely consume the sweetener in moderate amounts.
世卫组织下属的国际癌症研究机构将阿斯巴甜列为可能对人类致癌的物质。
The announcement does not mean that aspartame definitively causes cancer, W.H.O. experts said in a news conference; instead, it is a call for additional research into its health effects. The W.H.O. is not advising companies to withdraw products that contain aspartame or urging people to stop consuming it altogether, said Dr. Francesco Branca, director of the Department of Nutrition and Food Safety at the agency. “We’re just advising for a bit of moderation,” he said.
世卫组织专家在新闻发布会上表示，这一声明并不意味着阿斯巴甜一定会导致癌症，而是呼吁对其健康影响进行更多研究。世界卫生组织营养与食品安全部门主任弗朗西斯科·布兰卡博士表示，世界卫生组织并不建议公司撤下含有阿斯巴甜的产品，也不会敦促人们完全停止食用阿斯巴甜。“我们只是建议摄入要适度，”他说。
According to the W.H.O., it is safe to consume up to 40 milligrams of aspartame per kilogram of body weight per day. Using diet soda as a measure, the limit means that, by some estimates, a 150-pound person would need to drink more than a dozen cans each day to surpass it. The Food and Drug Administration is slightly more permissive with its daily safety limit. It states that people can have up to 50 milligrams of aspartame per kilogram of body weight each day.
根据世界卫生组织的数据，每天每公斤体重较多摄入40毫克阿斯巴甜是安全的。以无糖汽水为衡量标准，根据估算，这意味着一个体重68公斤的人每天需要喝十几罐才能超过这个限量。美国食品和药物管理局的每日安全限量则稍微宽松一些。它指出人们每天每公斤体重较多可摄入50毫克阿斯巴甜。
Given the vast quantities of sweetener under discussion, several experts said that consumers should not necessarily worry about the cancer risk of their aspartame consumption. Reaching that upper daily level of aspartame intake “isn’t casual consumption,” said Dr. Dale Shepard, a medical oncologist at the Cleveland Clinic. “This is making a project out of trying to get aspartame.”
鉴于所议甜味剂的使用量之广，几位专家表示，消费者不必担心食用阿斯巴甜的癌症风险。克利夫兰诊所的肿瘤内科医生戴尔·谢泼德博士说，“日常摄入并不会”达到每日阿斯巴甜摄入量上限。“要获取那么多阿斯巴甜没那么容易。”
