Seven-day nutrient intakes of 517 Head Start and day care children participating in USDA's Special Food Service Programs for Children in Nebraska, Kansas, and Texas were assessed. Protein, vitamin A, and ascorbic acid levels from diets served at the centers were judged to be adequate, while calories and B vitamins were below recommendations but proportional to each other. Calcium intake from center diets did not increase proportionately as the number of meals and snacks increased. Nutrient contributions were only slightly greater from center diets when two meals and two snacks were provided than when one meal and one snack were served. Home diets made substantial contributions to the diets of all children, resulting in little difference in total nutrient intakes between children receiving fewer or more meals and snacks at the centers. Iron was the nutrient supplied in least amount in relation to recommendations, when intakes from home and center were combined.
对参与美国农业部在 Nebraska、Kansas 和 Texas 为儿童提供的特殊食品服务项目的 517 名启智计划和日托儿童的七日营养摄入量进行了评估。中心提供的饮食中的蛋白质、维生素 A 和抗坏血酸水平被判定为充足，而卡路里和 B 族维生素低于推荐水平，但相互成比例。随着餐食和零食数量的增加，中心饮食中的钙摄入量并未成比例增加。提供两餐和两份零食时，中心饮食的营养贡献仅比提供一餐和一份零食时略高。家庭饮食对所有儿童的饮食贡献很大，导致在中心接受较少或较多餐食和零食的儿童之间总营养摄入量差异不大。将家庭和中心的摄入量相结合时，铁是相对于推荐量供应最少的营养素。
