School lunches must meet National School Lunch Program (NSLP) requirements to receive reimbursement. In this study, we sought to determine whether there are significant differences in nutrient content and nutritional quality between 2 menus meeting NSLP requirements.
A cross-sectional content analysis compared 6 weeks of a typical school lunch menu (TM) from an actual school district to a best practice school lunch menu (BPM) created by a registered dietitian based on Child and Adult Care Food Program (CACFP) best practices and Dietary Guidelines for Americans (DGA) healthy meal pattern recommendations. Daily nutrient content was determined using nutrient analysis software. Nutritional quality was computed using Healthy Eating Index (HEI) 2010.
For nutrients required for analysis, the BPM was lower in calories, saturated fat, and sodium and higher in protein, carbohydrate, and fiber (ps < .01). For other nutrients of concern, the BPM was higher in vitamin A, vitamin D, phosphorus, and magnesium (ps < .01). The BPM had higher HEI scores for nutritional quality (p < .001).
Results indicate the possibility for significant variation in nutritional quality of NSLP-qualifying lunches. Using CACFP best practices and DGA recommendations may significantly impact school lunch dietary quality.
学校午餐必须符合国家学校午餐计划（NSLP）的要求才能获得报销。在这项研究中，我们试图确定两份符合 NSLP 要求的菜单在营养成分和营养质量方面是否存在显著差异。
采用横断面内容分析，比较了一个实际学区的典型学校午餐菜单（TM）和由注册营养师根据儿童和成人护理食品计划（CACFP）最佳实践和美国人饮食指南（DGA）健康膳食模式建议创建的最佳实践学校午餐菜单（BPM）。使用营养分析软件确定每日营养成分。使用 2010 年健康饮食指数（HEI）计算营养质量。
对于需要分析的营养素，BPM 的卡路里、饱和脂肪和钠含量较低，而蛋白质、碳水化合物和纤维含量较高（p<.01）。对于其他关注的营养素，BPM 的维生素 A、维生素 D、磷和镁含量较高（p<.01）。BPM 的营养质量的 HEI 得分更高（p<.001）。
结果表明，符合 NSLP 资格的午餐的营养质量可能存在显著差异。使用 CACFP 最佳实践和 DGA 建议可能会显著影响学校午餐的饮食质量。
