From time to time, the Center for Science in the Public Interest, a Washington-based advocacy group, prepares an updated "report card" on changes in the American diet. The latest, collated by the nutritionist Bonnie Liebman and published in the September issue of the center's Nutrition Action Newsletter, is not one Americans should be especially proud of. 公共利益科学中心(Center for Science in the Public Interest)是一个总部设在华盛顿的宣传组织，它常常对美国人饮食习惯的变化作出评价，并不时发布最新的“成绩单”。其中最近的一份由营养师邦妮·利布曼(Bonnie Liebman)负责整理，并发表在该中心《营养行动通讯》(Nutrition Action Newsletter)的9月号上。老实说，这份“成绩单”可不怎么能令美国人感到自豪。 The analysis of changes in food consumption from 1970 to 2010 reveals that we still have a long way to go before we come close to meeting dietary guidelines for warding off obesity and chronic health problems like diabetes and heart disease. 这项关于1970年至2010年间食品消费变化的分析表明，要达到可抵御肥胖和慢性健康问题（如糖尿病和心脏病）的膳食指南的要求，美国人还有很长的路要走。 The news isn't all bad. Our consumption of added sweeteners, though still significantly higher than it was in 1970, has come down from the "sugar high" of 1999 when the average was 89 pounds per person. Nonetheless, an average of 78 pounds per person in 2010, mostly as sugar and high-fructose corn syrup, is still too much, Ms. Liebman points out. |
