研究了不同血糖负荷早餐对19名6 - 7岁儿童表现的影响。在为期四周的时间里，孩子们每天参加学校早餐俱乐部，吃三顿饭中的一顿。每顿饭提供的能量差不多，但血糖负荷不同。当单独工作时，在30分钟内，每隔10秒对一个孩子在教室里的行为进行评估，以衡量他们花在任务上的时间。记忆力是通过要求回忆一系列物品来评估的。保持注意力的能力是通过在各种延迟后要求回应来衡量的。当玩一款难度太大而无法成功的电子游戏时，消极行为的发生率被记录下来。在吃完低血糖负荷早餐两到三个小时后，他们在记忆力和保持注意力的能力测试中的表现更好，表现出的沮丧迹象更少，在课堂上单独学习时，他们最初花在任务上的时间更多。在影响学校行为的各种因素的背景下讨论了结果的重要性。(C) 2007爱思唯尔公司版权所有。
The impact of breakfasts of different glycaemic loads on the performance of nineteen children, aged six to seven years, was explored. Over a four week period, children attended a school breakfast club each day and ate one of three meals. Each meal offered a similar amount of energy but differed in their glycaemic load. When working individually, the behaviour of a child was rated in the classroom every ten seconds for 30 min to produce a measure of time spent on task. Memory was assessed by asking for the recall of a series of objects. The ability to sustain attention was measured by asking for a response after various delays. The incidence of negative behaviour was recorded when playing a video game that was too difficult to allow success. Two to three hours after a low glycaemic load breakfast had been consumed, performance on the tests of memory and the ability to sustain attention were better, fewer signs of frustration were displayed and initially more time was spent on task when working individually in class. The importance of the results was discussed in the context of the wide range of factors that influence behaviour in school. (C) 2007 Elsevier Inc. All rights reserved.
