Many school food services sell extra foods and beverages, popularly referred to as “competitive foods,” in addition to USDA school meals. On the basis of national survey data, most competitive foods and beverages selected by students are of low nutritional value. Recent federal legislation will allow schools that participate in USDA school meal programs to sell competitive foods only if the food items they sell meet nutrition standards based on the Dietary Guidelines for Americans. Concerns have been raised about the potential effects of limiting competitive foods on local school food service finances. However, national data indicate that only in a subset of schools do food services receive large amounts of revenues from competitive foods. These food services are typically located in secondary schools in more affluent districts, serving higher proportions of students who do not receive free or reduced price meals. Compared to other food services, these food services couple higher competitive food revenues with lower school meal participation. Increasing school meal participation could increase meal revenues to offset any loss of competitive food revenues. Replacing less-healthful competitive items with healthier options could also help maintain school food service revenues while improving the school food environment. Nationally consistent nutrition standards for competitive foods may encourage development and marketing of healthful products.
许多学校的餐饮服务除了供应美国农业部(USDA)规定的学校餐食外,还会额外提供一些食品和饮料,通常被称为“竞争食品”。根据全国性调查数据,大多数学生选择的竞争食品和饮料营养价值都较低。最近的联邦立法将允许参与 USDA 学校膳食计划的学校销售竞争食品,但前提是他们所销售的食品符合基于《美国人饮食指南》的营养标准。人们对限制竞争食品可能对当地学校餐饮服务财务状况产生的影响表示担忧。然而,全国数据表明,只有在一部分学校中,餐饮服务从竞争食品中获得了大量收入。这些餐饮服务通常位于较富裕地区的中学,为更多不享受免费或降价餐食的学生提供服务。与其他餐饮服务相比,这些餐饮服务的竞争食品收入较高,而学校餐参与率较低。提高学校餐参与率可以增加餐食收入,以弥补竞争食品收入的任何损失。用更健康的选择来替代不太健康的竞争食品,也有助于在改善学校食品环境的同时保持学校餐饮服务的收入。全国统一的竞争食品营养标准可能会鼓励健康产品的开发和营销。
