Abstract

This paper relies on 24-h dietary recall data from a nationally representative sample of approximately 3350 students to analyze the dietary intakes of students. Most US students eat at least five times during the day, and nearly all eat at least three times per day. The average daily intake of vitamins and minerals at least meets the recommended dietary allowances (RDAs). Overall, students consume more food energy on average than recommended, suggesting that some may be at risk of consuming more food energy than is optimal. Students also consume more protein, total fat, saturated fat, and sodium than is recommended for good health. National School Lunch Program (NSLP) participants' mean intakes of most nutrients at lunch meet the program goal of at least one-third of the RDA. NSLP participants, however, consume more fat, saturated fat, and sodium than is recommended. School Breakfast Program (SBP) participants' mean intakes of most nutrients at breakfast also exceed the program goal of one-fourth of the RDA. However, their breakfast intakes of saturated fat as a percentage of food energy, cholesterol, and sodium exceed dietary recommendations.

摘要

本文基于对约3350名具有全国代表性的学生样本进行的24小时饮食回顾数据,来分析学生的饮食摄入量。大多数美国学生一天至少吃五次饭,几乎所有学生每天至少吃三次饭。维生素和矿物质的日均摄入量至少达到了推荐膳食摄入量(RDA)。总体而言,学生平均摄入的食物能量比推荐量多,这表明一些学生可能面临摄入超过最佳量的食物能量的风险。学生摄入的蛋白质、总脂肪、饱和脂肪和钠也超过了健康所需的推荐量。参加国家学校午餐计划(NSLP)的学生午餐时大多数营养素的平均摄入量达到了该计划至少三分之一RDA的目标。然而,参加NSLP的学生摄入的脂肪、饱和脂肪和钠超过了推荐量。参加学校早餐计划(SBP)的学生早餐时大多数营养素的平均摄入量也超过了该计划四分之一RDA的目标。然而,他们早餐中饱和脂肪占食物能量的百分比、胆固醇和钠的摄入量超过了饮食建议量。
