Abstract

Various federal policies have weakened school meal nutrition standards in the United States since the passage of the Healthy, Hunger-Free Kids Act in 2010, including temporary school meal nutrition waivers to promote post-COVID-19 pandemic recovery. This study used school menu and nutrient data from a nationally representative sample of 128 elementary school districts to examine differences in nutrients (average calories, total fat, saturated fat, sodium, total sugar, and fiber) and alignment with United States Department of Agriculture (USDA) sodium targets in 2019 (pre-pandemic) and in 2022 (post-pandemic). Data were analyzed using analysis of variance accounting for repeated measures within school districts, adjusting for geographic region and urbanicity. Small differences in the nutrient content for both breakfast and lunch were observed between 2019 and 2022. Most weeks met USDA sodium Target 1 for breakfast (≥95% of weeks) and Target 1 (≥96% of weeks) and Target 1A for lunch (≥92% of weeks) in both 2019 and 2022, although compliance decreased slightly when condiments were included. Additionally, meals provided on average 57 g of total sugar. Overall, many meals are already in alignment with lower sodium targets. Simple strategies, such as offering lower sodium condiments, can further reduce sodium in school meals. The total sugar levels observed highlight that the USDA should consider limits on added sugars in school meals.

摘要

自 2010 年《健康,无饥饿儿童法案》通过以来,美国的各种联邦政策削弱了学校膳食营养标准,包括临时学校膳食营养豁免,以促进大流行后 COVID-19 的恢复。本研究使用来自全国代表性的 128 个小学区样本的学校菜单和营养数据,检查了营养素(平均卡路里、总脂肪、饱和脂肪、钠、总糖和纤维)的差异,并与美国农业部(USDA)在 2019 年(大流行前)和 2022 年(大流行后)的钠目标一致。数据使用在学区内重复测量的方差分析进行分析,调整了地理区域和城市性。2019 年和 2022 年之间,早餐和午餐的营养成分含量略有差异。在早餐方面,大多数周都达到了 USDA 目标 1(≥95%的周)和目标 1(≥96%的周)以及午餐的目标 1A(≥92%的周),尽管在包括调味品时,合规性略有下降。此外,每餐平均提供 57 克总糖。总体而言,许多餐点已经符合较低的钠目标。简单的策略,如提供低钠调味品,可以进一步减少学校餐中的钠。观察到的总糖水平突出表明,美国农业部应考虑在学校餐中限制添加糖。
