Let's look at our example one more time.
让我们再看一下第一个例子
Again, focus on the right hand side of the food label, highlighted here in purple.
同样，还是关注食物标签右侧的紫色区域
The percent daily value heading is at the top of the column
日营养摄入比例最高的列在该栏的最上端
as listed below are the percentages of nutrients.
下面是各种营养物质百分比
You can see that for one serving of macaroni and cheese
你可以发现对于2000卡里路饮食建议的脂肪总量来说
you would consume 18% of your total daily allotment for what is recommended in a 2000 calorie diet for total fat.
每份通心粉奶酪提供了日摄入脂肪量的18%
Similarly one serving of macaroni and cheese will yield 15% of your daily limit of saturated fat.
相似地，每份通心粉奶酪中含有的饱和脂肪占建议日摄入量的15%
Another nutrient to notice here is sodium,
另一项要注意的营养物质是钠
with just one serving of this food you would have 20% of your daily limit for sodium.
每份该食物中其占有建议日摄入量的20%
As mentioned in the previous slide, 20% or more is considered high.
如上张课件中提到的20%及以上就被认为是高含量了
So this food product has a high amount of sodium.
因此这种食物钠含量较高
Even though this product has a lot of sodium and nutrients that you should limit
尽管该食品含有高量的钠和应有限量食用的营养物质
it also has 20% daily value of calcium.
它还含有20%的钙建议日摄入量
This means that one serving of macaroni and cheese has a high amount of calcium,
也就是说每份通心粉奶酪含有大量钙
which is a nutrient to be sure you consume enough of.
这是人体应当摄取足量的物质
One of the best uses of percent daily values is that
日营养摄入比例
it allows a quick way to compare one food product to another.
最好的用途之一就是可以比较不同产品
If you are in the grocery store and wanted to find out
如果你在杂货店想知道
if this particular brand of macaroni and cheese is a healthier choice than the next brand on the shelf,
是否这种牌子的通心粉奶酪比另一种牌子的更健康
you can easily compare the percent daily values for each of the nutrients and get a quick idea.
只要简单地比较日营养摄入比例，就能快速知道结果
For instance, if the other brand has a daily value of 16% for total fat,
比如，如果另一种品牌的产品中全部脂肪摄入量占日营养摄入的16%
14% for saturated fat and 17% for sodium,
饱和脂肪占14%，钠占17%
it would likely be that the other brand is a healthier choice than the brand shown here on the slide
那么这个牌子就比我们上张课件中讲到的那个牌子更健康
since the percent daily values are all based on the same common denominator,
因为日摄入营养比例的分母相同
which is a 2000 calorie diet
即2000卡热量的食物
you can compare one food product to another by comparing the percent daily values listed on the food label.
因此你可以通过比较食物标签上的日营养摄入百分比来比较不同产品
This presentation has explained how to read a food label
该讲介绍了如何阅读营养标签
and hopefully has made understanding these food labels a bit easier.
希望你能对此有一个更清楚的了解
Food labels contain a wealth of information if you know what to look for, how to understand it,
如果你知道怎样阅读理解食品标签并将其用于健康食品的选择
and then apply it to making healthy food choices.
那么它提供的信息还是很丰富的
The US food and drug administration dictates that food labeling is required for most prepared foods
美国食品及药物管理局规定大多数预加工食品如各种面包
such as breads, cereals, canned and frozen foods, snacks, deserts, drinks and many more.
谷类食品，灌装及冷冻食品，小吃，点心，饮料等都需要提供食品标签
However nutrition labeling for raw produce such as fruit and vegetables and fish is voluntary.
而未加工产品如蔬菜水果鱼等的营养标签则不是必须的
Reading a nutrition facts label or food label can be easily broken down into six sections,
营养标签或健康标签可以分为六个部分
which are serving size, calories, nutrients to limit, nutrients to get enough of, footnote and percent daily value.
食用分量，热量，需限量食用的营养物质，需足量食用的营养物质，补充说明和每日摄入百分比
It is best to start at the top of the food label and then work your way down,
你最好从食物标签最顶端一步步向下看
noticing all the sections we have discussed.
这些我们都已讨论
Remember the percent daily value offers a quick and easy way to compare one food product to another
记住，日摄入营养百分比提供了一个快捷简单的方法来比较不同商品
so that you can select the product that is the most healthy choice.
因此你可以选择最健康的那些食品
