减少含糖饮料和高脂肪、高盐和甜食的学校食品政策变化对中学生能量消耗的潜在影响进行了评估。从23所学校获得了一个学年小吃店的销售额。计算了每种产品的能量含量，并确定了减少份量所节省的能量。每个学生每天购买约111千卡热量；当减少份量取代大份量时，每天可节省47千卡热量。这些发现应该为学校食物环境中食物份量的变化可能影响能量平衡提供一些保证。
The potential impact of a school food policy change reducing sweetened beverage and high-fat, salty, and sweet food portions on energy consumption of middle-school students was assessed. Snack bar sales for one school year were obtained from 23 schools. Energy content was calculated for each item and energy savings from reduced portion size was determined. Per student, about 111 kcal per day was purchased; 47 kcal per day was saved when reduced portion sizes were substituted for the large servings. These findings should provide some assurance that changes in food portion sizes in school food environments could impact energy balance.
