3.Sugar Causes Hyperactivity

3.糖会导致多动

What parent of little ones hasn't heard that eating too much sugar will cause her kids to get too keyed up, or a bit hyper? And it often seems anecdotally true. Watch as kids scarf down candy, cake and soda at a birthday party, then promptly¹ run wild all over the place, screeching² and screaming. But do we ever stop to think that maybe they're just overstimulated by the excitement of the birthday party itself? Or ponder the fact that lots of adults pig out on sugary snacks and desserts with no similar aftereffects?

吃太多糖的小孩子会变得过于兴奋多动，这种说法估计家长们都听说过吧？有意思的是，看起来似乎真是这么回事。在生日聚会上，看着孩子们打翻糖果、蛋糕和苏打水，看着他们一下子疯跑起来，尖叫，大笑的样子。但是我们可曾停下来仔细想想，他们这样做只是因为生日聚会过度兴奋而已？可曾思考过，为什么很多大人在狼吞虎咽的吃糖果和点心后没有出现类似的情况？

There have been extensive studies about the relationship between sugar and hyperactivity, and no link has been found between the two. A group of researchers further reviewed several reputable studies and concluded that sugar in children's diets doesn't affect their behavior, apart from a small subset of kids. Interestingly, another study, published in the Journal of Abnormal Child Psychology³, asked mothers of boys whom they thought were "sugar-sensitive" to rate their sons' behavior after they'd had soda. The mothers of the boys who'd had a sugar-filled soda thought their children's behavior was more hyperactive than the boys who'd been given an artificially sweetened soda. The trick was that all the kids in the study had been given an artificially sweetened drink, meaning that the behavior was based on perception rather than sugar.

有很多关于糖和多动行为的研究，但还没发现这两者之间的联系。有研究人员进一步回顾了一些颇具争议的研究，得出的结论是：除了一小部分孩子以外，孩子们的摄糖量并不会影响他们的行为。。有趣的是，另一项发表在《儿童病态心理学杂志》上的研究曾要求一些认为自己的孩子对糖敏感的母亲们观察孩子喝了苏打水之后的行为变化。饮用含糖苏打水的孩子们的母亲认为她们的孩子比那些没饮用过含糖苏打水的孩子们的行为更活跃。这项研究耍了个小花招——其实所有孩子们的饮料都含糖，这就意味着母亲对于孩子行为的判断是基于感觉而不是糖的作用。
