为了探讨不同能量早餐对小学生认知能力和身体耐力的影响，从北京市２所小学三年级中随机抽取了４个班共１５１名小学生作为研究对象，在１周的星期一到星期五随机食用能量高的早餐 Ａ 或能量低的早餐 Ｂ，并在这周的星期二至星期五上午的第３、４节课进行加法、乘法、数字核对、逻辑、创造力、身体耐力和自我感觉共７项测试，结果食用不同能量早餐的学生间其加法、乘法、数字核对、逻辑测试的平均完成率、平均正确率没有显著性的差异，其创造力测试的得分、重复数的差异也没有显著性，其身体耐力和自我感觉测试也没有显著性的差异。早餐能量摄入对学生认知能力的影响尚需进一步研究。
In order to explore the effect of different energy breakfast on the cognitive ability and endurance of pupils, 151 pupils in 4 classes were randomly selected from the third grade of 2 primary schools in Beijing.
