饮食不健康的后果或许已经被美国《临床儿科学》月刊最近发表的一项新研究道破。该研究表明,经常吃麦当劳、肯德基、必胜客等快餐的孩子在学校的成绩不如其他孩子。

美式快餐

这项研究的带头人、美国俄亥俄州立大学的Purtell KM说:“研究的重点是孩子的食物摄取是如何影响儿童肥胖这一普遍现象的。我们的发现提供了证明吃快餐与另一个问题——即学习成绩较差——有关系的证据。”

这项研究使用了对8544名美国学生采集的数据,记录了他们在10岁时的快餐摄取情况,然后把这些数据与他们13岁时的阅读、数学与科学成绩联系起来。

比如在科学成绩方面,从来不吃快餐的孩子得分为83分,而每天都吃快餐的孩子的平均得分为79分。《每日电讯报》报道说,解释这一现象的理论是以脑化学为基础的——比如缺铁(这会导致发育速度减慢)以及食谱中含糖量的影响等等。

当然,快餐受欢迎的原因之一是它很便宜。经常给孩子吃快餐的家庭收入较低,这意味着他们提供其他有助于孩子学习的东西(比如书籍、安静的学习环境以及 家长帮助等等)的能力也较弱。当你在从事许多低薪的兼职工作时,为子女提供“直升机式教育”根本不可能。学习成绩通常反映着阶级差异。但是,俄亥俄州立大 学的研究声称已经证明的事情是,即使把“诸多潜在的干扰因素包括社会经济学指标(即贫富水平)、体育运动和看电视多少考虑在内”,吃快餐也仍然是一个影响 因素。

这项研究的另一个方面同样令人瞠目结舌:即究竟有多少美国孩子是靠吃快餐长大的。研究人员说,在他们采样的孩子中,52%的孩子在前一周最多的吃过3次快餐,10%的孩子在前一周吃过4到6次快餐,另有10%的孩子在前一周每天都吃快餐。
