Although food cooked at home is far more healthful than meals eaten at restaurants,Americans are dining out more than ever,the U.S.Agriculture Department said Tuesday.Restaurant food accounted for 39 percent of U.S.meals bought in 1996,up from 26 percent in 1970,the department said in a report,“Away-From-Home Foods Increasingly Important to Quality of American Diet.” “While the nutritional quality of foods consumed by Americans has improved overall,foods prepared at home are generally much more healthful than away-from-home foods,” the department said.“Despite nutritional gains at home,Americans will find it difficult to improve their diets because they purchase so many meals outside the home,” the study said.While the nutritional content of food prepared both at home and in restaurants has improved in recent years,food eaten out contains more of the nutrients Americans typically eat too much of,including fat and saturated fat（饱和脂肪）,and less of what is lacking from most diets,such as calcium,fiber and iron.The department recommended nutrition education programs should place more emphasis on teaching U.S.consumers about how to order healthful meals when dining out.Improved diets have been found to prevent risk of heart disease,stroke,cancer,diabetes,osteoporosis-related hip fractures（与骨质疏松症有关的髋关节骨折） and neural tube birth defects（神经管先天缺损）.Osteoporosis-related hip fractures cost up to $10.6 billion each year in the United States in medical care expenses,missed work and premature deaths,the department said.

美国农业部在周四指出：尽管在家就餐比在餐馆就餐要健康得多,但美国民众外出就餐比以往更加频繁了.农业部在一份报告中说：“自1970年到1996年,美国人下馆子就餐的比重由26%上升到39%,因此外出就餐所吃的食品越来越影响着美国人的饮食质量.尽管在美国人的食物中营养价值整体提高了,但通常在家里做的食物比在外面吃的食物要健康得多.虽然在家吃饭能增强营养,但由于美国人在外面吃惯了,所以他们很难改善他们的饮食.”研究表明：虽然这几年家里的饭菜和餐厅的饭菜在营养方面都有所提高,但外出就餐摄入过多的营养物质如脂肪、饱和脂肪酸,而缺乏像钙、纤维素和铁等营养物质.这种“多和少”在美国食谱中很典型.农业部建议营养教育课程应该着重教美国消费者在外出就餐时如何点健康的食物来吃.改良的饮食够规避得心脏病、中风、癌症、糖尿病、骨质疏松引起的骨折和神经管先天缺损的风险.农业部说：“骨质疏松导致的髋关节骨折每年使美国医疗保障、失业保障、早逝支出的成本增加了10.6亿美元,”
