“食欲”英语怎么说

　　名词解释：食欲，指人进食的欲望。如：增进食欲。

　　Australian researchers have found that junk food can suppress a person's appetite for a balanced, healthy diet.

　　The researchers experimented on rats and found that when they were put on a diet of junk food – like cookies, pie and cake – for two weeks, they not only gained weight but also lost their desire to seek out different foods. The findings help explain how excessive consumption of junk food can change behavior and lead to overeating and obesity.

　　The interesting thing about this finding is that if the same thing happens in humans, eating junk food may change our responses to signals associated with foods.

　　澳大利亚的研究人员发现，垃圾食品能够抑制人们对均衡、健康饮食的食欲。

　　这些研究人员在老鼠身上做实验，发现当给老鼠喂食两周的诸如饼干、馅饼和蛋糕等垃圾食品后，它们不仅体重增加了，而且还失去了寻找不同的食物的欲望。这项发现能够帮助解释过度摄入垃圾食品是如何改变人们的行为，导致过度饱食和肥胖的。

　　这个发现的有趣之处是，如果人类身上发生同样的事情，食用垃圾食品可能会改变我们对与食物有关的信号的反应。
