国家学校午餐计划一直以适度的营养标准为指导，推动消费的食物的可口性没有得到足够的关注。学校食物垃圾可能会对决策者、学生和他们的家庭产生重要的营养和成本影响。研究了与学校餐饮垃圾相关的营养损失和经济成本。这项研究还评估了学校提供的食物是否有效地替代了学生食用的食物。在一项为期两年的试点研究(2007-2009年)中，收集了波士顿两所厨师倡议学校(n=1609)和两所对照学校(n=1440)的中学生的盘子垃圾测量数据，在该研究中，一名专业厨师培训食堂工作人员制作更健康的学校膳食。计算了与食物浪费相关的成本，并将食物消耗的百分比与85%的黄金标准进行了比较。分析是在2010-2011年进行的。总体而言，学生摄入的营养素低于所需/推荐的水平。据估计，波士顿中学每年有432,349美元的食物(占总食物预算的26.1%)被中学生丢弃。对于大多数膳食成分来说，消耗的比例明显低于85%。波士顿的中学生中有大量的食物浪费。总体而言，学生的营养摄入水平低于学校膳食标准，所提供的食物不是所消费食物的有效替代品。与丢弃食品相关的成本很高；如果在全国范围内换算为学校午餐，每年大约浪费123884.64万美元。如果学校对学校膳食的质量和可口性给予更多关注，学生将受益。
The National School Lunch Program has been guided by modest nutrient standards, and the palatability of meals, which drives consumption, receives inadequate attention. School food waste can have important nutritional and cost implications for policy makers, students, and their families. Nutrient losses and economic costs associated with school meal waste were examined. The study also assessed if school foods served were valid proxies for foods consumed by students. Plate waste measurements were collected from middle school students in Boston attending two Chef Initiative schools (n=1609) and two control schools (n=1440) during a two-year pilot study (2007-2009) where a professional chef trained cafeteria staff to make healthier school meals. The costs associated with food waste were calculated and the percent of foods consumed was compared with a gold standard of 85% consumption. Analyses were conducted in 2010-2011. Overall, students consumed less than the required/recommended levels of nutrients. An estimated $432,349 of food (26.1% of the total food budget) was discarded by middle school students annually at lunch in Boston middle schools. For most meal components, significantly less than 85% was consumed. There is substantial food waste among middle school students in Boston. Overall, students' nutrient consumption levels were below school meal standards and foods served were not valid proxies for foods consumed. The costs associated with discarded foods are high; if translated nationally for school lunches, roughly $1,238,846,400 annually is wasted. Students would benefit if additional focus was given to the quality and palatability of school meals.
