去超市购物的时候，你会着重的去看看你所购买的商品标签吗?有多少人都忽略了这个小东西而直接放入购物车。而你知道吗，这个小小的标签其实蕴含了很多的信息。

　　知道如何解读营养成分标签可以帮助我们日常适当的营养摄取和饮食。这些标签上的信息没什么难的。当这些信息的意义被我们所知时，了解哪些食品是好的，哪些是坏的就轻而易举了。

　　1.Serving Size

　　Each Nutrition Facts label lists its item's serving size and the number of servings per package. It's important to understand the number of servings in a package so you don't eat more.

　　2.Calories

　　The label notes calories, too. Calories are a measure of how much energy a serving of food provides. If one serving equals 200 calories but you ate two servings, then you consumed 400 calories worth of energy.

　　3.Nutrients

　　The food label provides two groups of nutrients: nutrients you should limit (fat, cholesterol, sodium) and nutrients you should have (fiber, vitamins, minerals). Cutting out saturated fats and sodium while increasing vitamin and mineral content should be a focus when reading food labels.

　　4.Daily Value Percent

　　Food contains a percentage under the label's heading Daily Value or DV, which is set at a 2,000-kilocalories average. The percentages on a food product reflect the recommended amount at a 2,000-kilocalorie daily level.
