We assessed the impact of legislation that established nutrition standards for foods and beverages that compete with reimbursable school meals in California.
We used documentation of available foods and beverages, sales accounts, and surveys of and interviews with students and food service workers to conduct 3 studies measuring pre- and postlegislation food and beverage availability, sales, and student consumption at 99 schools.
Availability of nutrition standard-compliant foods and beverages increased. Availability of noncompliant items decreased, with the biggest reductions in sodas and other sweetened beverages, regular chips, and candy. At-school consumption of some noncompliant foods dropped; at-home consumption of selected noncompliant foods did not increase. Food and beverage sales decreased at most venues, and food service à la carte revenue losses were usually offset by increased meal program participation. Increased food service expenditures outpaced revenue increases.
Regulation of competitive foods improved school food environments and student nutritional intake. Improvements were modest, partly because many compliant items are fat- and sugar-modified products of low nutritional value. Additional policies and actions are needed to achieve more substantive improvements in school nutrition environments and student nutrition and health.
我们评估了加利福尼亚州为与可报销学校餐食竞争的食品和饮料制定营养标准的立法的影响。
我们使用了可用食品和饮料的文件、销售账目,以及对 99 所学校的学生和餐饮工作人员进行的调查和访谈,来进行 3 项研究,以衡量立法前后食品和饮料的供应、销售情况以及学生的消费情况。
符合营养标准的食品和饮料的供应增加了。不符合规定的项目减少了,减少最多的是苏打水和其他含糖饮料、普通薯片和糖果。一些不符合规定的食物的在校消费有所下降;在家中对某些不符合规定的食物的消费并没有增加。大多数场所的食品和饮料销售下降,而餐饮服务的点菜收入损失通常被增加的餐计划参与所抵消。增加的餐饮服务支出超过了收入的增加。
对竞争食品的监管改善了学校的食品环境和学生的营养摄入。改善是适度的,部分原因是许多符合规定的项目是低营养价值的高脂肪和高糖的改良产品。需要采取更多的政策和行动,以在学校营养环境和学生营养和健康方面取得更实质性的改善。
