在剑桥雅思14Test1写作—饼状图中，三张饼图展示了美国人在日常几餐（早餐、午餐、晚餐和零食）中对钠、饱和脂肪和添加糖这三种营养素的平均摄入量。

The pie charts illustrate the average content of three types of nutrients, sodium, saturated fat and added sugar, in typical daily meals, namely breakfast, lunch, dinner and snacks, eaten in the USA.
Initially, when we look at the breakfast and lunch segments of each chart, it seems that throughout all three nutrients have approximately the same value. Breakfast shows 14%(sodium),16%(saturated fat)and 16%(added sugar), whereas lunch was 29%, 26%and 19%.
Moving on to the other two meals, we can clearly see that there was a much greater variety.Dinner ranged from 43%to 23%and snacks had the inverse trend, ranging from 14% to 42%.
Overall, from the charts it seems that the dinner is the least healthy meal with snacks being not far behind. Breakfast comes out as the healthiest meal to eat, with lunch being somewhere in the middle.

在剑桥雅思14Test1写作—饼状图中，本题的三张饼图展示了美国人在日常几餐（早餐、午餐、晚餐和零食）中对钠、饱和脂肪和添加糖这三种营养素的平均摄入量。
首先,我们来看每个饼图中的早餐和午餐部分。这三类营养物质(在每餐中)的摄入比例似乎差不多。早餐中有14%的钠、16%的饱和脂肪、及16%的摄入的糖,而午餐中这三类的比例分别是29%、26%和19%。
接下来再看另外两餐,我们可以很清楚地看到它们的差別较大。晚餐中三类物质的比例从43%到23%不等,而零食中的含量正好相反,从14%至42%不等。总之,从以上图中可以看出,晚餐是吃得最不健康的,零食紧随其后。而早餐是吃得最健康的,午餐居中。
综上所述，剑桥雅思14Test1写作—饼状图的数据表明，晚餐是最不健康的一餐，零食紧随其后。早餐则是最健康的，午餐居中。
