Let's look at our example one more time.
讓我們再看一下第一個例子
Again, focus on the right hand side of the food label, highlighted here in purple.
同樣，還是關注食物標簽右側的紫色區域
The percent daily value heading is at the top of the column
日營養攝入比例最高的列在該欄的最上端
as listed below are the percentages of nutrients.
下面是各種營養物質百分比
You can see that for one serving of macaroni and cheese
你可以發現對于2000卡里路飲食建議的脂肪總量來說
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攝入脂肪量的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飽和脂肪占建議日攝入量的15%
Another nutrient to notice here is sodium,
另一項要注意的營養物質是鈉
with just one serving of this food you would have 20% of your daily limit for sodium.
每份該食物中其占有建議日攝入量的20%
As mentioned in the previous slide, 20% or more is considered high.
如上張課件中提到的20%及以上就被認為是高含量了
So this food product has a high amount of sodium.
因此這種食物鈉含量較高
Even though this product has a lot of sodium and nutrients that you should limit
盡管該食品含有高量的鈉和應有限量食用的營養物質
it also has 20% daily value of calcium.
它還含有20%的鈣建議日攝入量
This means that one serving of macaroni and cheese has a high amount of calcium,
也就是說每份通心粉奶酪含有大量鈣
which is a nutrient to be sure you consume enough of.
這是人體應當攝取足量的物質
One of the best uses of percent daily values is that
日營養攝入比例
it allows a quick way to compare one food product to another.
最好的用途之一就是可以比較不同產品
If you are in the grocery store and wanted to find out
如果你在雜貨店想知道
if this particular brand of macaroni and cheese is a healthier choice than the next brand on the shelf,
是否這種牌子的通心粉奶酪比另一種牌子的更健康
you can easily compare the percent daily values for each of the nutrients and get a quick idea.
只要簡單地比較日營養攝入比例，就能快速知道結果
For instance, if the other brand has a daily value of 16% for total fat,
比如，如果另一種品牌的產品中全部脂肪攝入量占日營養攝入的16%
14% for saturated fat and 17% for sodium,
飽和脂肪占14%，鈉占17%
it would likely be that the other brand is a healthier choice than the brand shown here on the slide
那么這個牌子就比我們上張課件中講到的那個牌子更健康
since the percent daily values are all based on the same common denominator,
因為日攝入營養比例的分母相同
which is a 2000 calorie diet
即2000卡熱量的食物
you can compare one food product to another by comparing the percent daily values listed on the food label.
因此你可以通過比較食物標簽上的日營養攝入百分比來比較不同產品
This presentation has explained how to read a food label
該講介紹了如何閱讀營養標簽
and hopefully has made understanding these food labels a bit easier.
希望你能對此有一個更清楚的了解
Food labels contain a wealth of information if you know what to look for, how to understand it,
如果你知道怎樣閱讀理解食品標簽并將其用于健康食品的選擇
and then apply it to making healthy food choices.
那么它提供的信息還是很豐富的
The US food and drug administration dictates that food labeling is required for most prepared foods
美國食品及藥物管理局規定大多數預加工食品如各種面包
such as breads, cereals, canned and frozen foods, snacks, deserts, drinks and many more.
谷類食品，灌裝及冷凍食品，小吃，點心，飲料等都需要提供食品標簽
However nutrition labeling for raw produce such as fruit and vegetables and fish is voluntary.
而未加工產品如蔬菜水果魚等的營養標簽則不是必須的
Reading a nutrition facts label or food label can be easily broken down into six sections,
營養標簽或健康標簽可以分為六個部分
which are serving size, calories, nutrients to limit, nutrients to get enough of, footnote and percent daily value.
食用分量，熱量，需限量食用的營養物質，需足量食用的營養物質，補充說明和每日攝入百分比
It is best to start at the top of the food label and then work your way down,
你最好從食物標簽最頂端一步步向下看
noticing all the sections we have discussed.
這些我們都已討論
Remember the percent daily value offers a quick and easy way to compare one food product to another
記住，日攝入營養百分比提供了一個快捷簡單的方法來比較不同商品
so that you can select the product that is the most healthy choice.
因此你可以選擇最健康的那些食品
