背景：2010年《健康无饥饿儿童法案》要求美国农业部更新全国学校午餐计划的营养标准。2012-2013学年实施了新政策。在这些变化之后，有传闻说食物浪费增加了。需要进行实证研究，以可靠地衡量这一政策变化前后的学生人数和盘子浪费。研究方法：食物消费和浪费是每年从一个城市，低收入学区的12所学校的中学生队列收集之前（2012年春季）和之后（2013年春季和2014年）的政策变化。广义线性回归被用来比较前与后的政策选择和消费的主菜，水果，蔬菜和牛奶。结果如下：与2012年相比，2014年，学生选择水果的比例从54%显著增加到66%，水果消费量保持在74%的高位。每增加一种随餐提供的水果，学生对水果的选择就增加9%。选择蔬菜的学生比例从68%下降到52%，但选择蔬菜的学生多吃了近20%，有效减少了蔬菜浪费。入口消耗量从71%显著增加到84%，从而也减少了浪费。结论：学生对新午餐反应积极。他们吃了更多的水果，扔掉了更少的主菜和蔬菜，喝了同样多的牛奶。总的来说，修订后的膳食标准和政策似乎大大减少了学校食堂的餐盘浪费。
Background: The 2010 Healthy, Hunger-Free Kids Act required the USDA to update the nutrition standards of the National School Lunch Program. New policies were implemented in the 2012–2013 school year. These changes were followed by anecdotal reports of increased food waste. Empirical research is needed to reliably measure student intake and plate waste before and after this policy change. Methods: Food consumption and waste was collected annually from a cohort of middle school students in 12 schools in an urban, low-income school district before (spring 2012) and after (spring 2013 and 2014) policy changes. Generalized linear regression was used to compare pre- versus postpolicy selection and consumption of entrées, fruits, vegetables, and milk. Results: Comparing 2012 to 2014, the percentage of students choosing fruit significantly increased from 54% to 66% and fruit consumption remained high at 74%. Student selection of fruit increased by 9% for each additional type of fruit offered with the meal. The proportion of students who chose a vegetable dropped from 68% to 52%, but students selecting vegetables ate nearly 20% more of them, effectively lowering vegetable waste. Entrée consumption increased significantly from 71% to 84%, thereby also decreasing waste. Conclusions: Students responded positively to the new lunches. They consumed more fruit, threw away less of the entrees and vegetables, and consumed the same amount of milk. Overall, the revised meal standards and policies appear to have significantly lowered plate waste in school cafeterias.
