SUCROSE AND FOOD SELECTION BY PRESCHOOL CHILDREN

这个行为研究项目的总体目标是确定 学龄前儿童饮食中蔗糖取代营养素的程度 并促进蛋白质-能量摄取调节的紊乱。 以前在这一领域的研究发现，学龄前儿童 儿童在以下情况下会摄入大量的可口饮料 它是在一餐中提供的，不会减少他们对其他食物的摄入量 食物中的食物，提供时平均多摄入25%的卡路里 他们进餐时喝巧克力奶比提供纯牛奶时要好。这个 这里提出的研究将试图解释这种失败在 自我节制饮食，外加测试蔗糖对零食和 学龄前儿童进食。这项研究的设计包括 每周两天供应午餐和上午和下午的小吃 12周至120名学龄前儿童，要么在日托中心(N= 80人)或在私人家庭(N=40人)。轮流菜单上的四餐将是 使用。在十二个月期间，受试者每餐将被提供六次 一周内，三种测试饮料各两次，纯牛奶， 巧克力加蔗糖的牛奶和巧克力阿斯巴甜的牛奶。 本科生研究助理将把午餐运送到 受试者，记录所吃食物的顺序和时间 吃每一样东西的时间，并测量食物和饮料的数量 在午餐和零食中食用。数据分析的重点是 行为举止，而不是营养。预计这些调查结果 将为健康的学龄前儿童提供标准饮食的基线 重病儿童的饮食行为可能会对儿童造成伤害 被比较。这些发现将对我们的研究具有重要意义 蔗糖在儿童肥胖发展中的作用。

The overall objective of this behavioral research project is to determine the extent to which sucrose displaces nutrients in the diet of preschool children and promotes the disruption of protein-energy intake regulation. Previous research in this area has yielded the finding that preschool children consume enormous quantities of a highly palatable beverage when it is offered in a meal, without decreasing their intake of other food items in the meal, consuming a mean of 25% more calories when offered chocolate milk with their meals than when offered plain milk. The research proposed here would attempt to explain this failure in self-regulatory eating, plus test the effects of sucrose on snack and meal eating by preschool children. The design of this study involves serving lunch and a morning and afternoon snack two days a week for twelve weeks to 120 preschool children, either in daycare centers (N = 80) or in private homes (N = 40). Four meals on a rotating menu will be used. Subjects will be offered each meal six times during the twelve week period, twice with each of the three test beverages, plain milk, chocolate sucrose-sweetened milk, and chocolate aspartame-flavored milk. Undergraduate research assistants will transport the lunches to the subjects, record the order of food items consumed and the amount of time spent eating each item, and measure the amount of food and beverages consumed during lunch and snacks. The emphasis of the data analysis will be behavioral, rather than nutritional. It is expected that the findings will provide a baseline of normative eating by healthy, preschool children against which the eating behavior of seriously ill children can be compared. These findings would have important implications for the role of sucrose in the development of childhood obesity.
