Next we will talk about the two sections highlighting information about nutrients on the food label.
下面我们要讨论一下食品标签上关于营养物质的两块显著信息
In general you can think of the nutrient sections in two different parts.
大体上你可以认为营养成分由两部分组成
The first part which is highlighted in our example in yellow on the next slide,
第一部分是下张课件例子中的黄色区域
are the group of nutrients that you should limit.
这部分是我们应该控制摄入的营养成分
These nutrients are total fat,
这些成分全部是脂肪
which include saturated fat and trans fat, cholesterol and sodium.
包括饱和脂肪，转化脂肪，胆固醇和钠
In the united states most people consume adequate amounts or too much of these nutrients.
大多数美国人过多食用这些营养物质
And they are also linked to an increased risk of chronic diseases.
它们还会增加慢性病的发病几率
Such chronic diseases are heart disease high blood pressure and some cancers.
如心脏病，高血压和癌症
The other group of nutrients which are highlighted in blue on the next slide
营养成分的另一部分就是下张课件中的蓝色区域
are ones that you should be sure to get enough of.
这些物质是我们必须充足获取的
They are dietary fiber, vitamin A, vitamin C, calcium and iron.
它们包括食用纤维，维生素A，维生素C，钙和铁
Opposite to the first group,
与上类物质相反
this group of nutrients are ones that Americans tend to not get enough of.
美国人对这些物质的食用有待加强
So you should aim to consume adequate amounts.
因此我们要注意注入足量的此类物质
These nutrients can reduce risk of some diseases or conditions.
它们能够减缓一些疾病的发病率和发病条件
Examples are a lack of calcium that can lead to osteoporosis
例如，缺钙会引起骨质疏松症
and adequate fiber is linked to healthy bowel function.
充足的维生素能够保证健全的肠功能
Now let's take a look at these nutrients on the food label.
现在让我们看一下食品标签上的营养物
Shown here in yellow total fat, saturated fat,
这里黄色区域是脂肪总量，包括饱和脂肪
trans fat, cholesterol and sodium are shown here with the amounts of each nutrient listed beside it.
转化脂肪，胆固醇和钠，旁边分别列举了其含量
Again you should aim to consume limited amounts of this group of nutrients.
再次说明你应该有节制地食用这些物质
The macaroni and cheese example has fairly large amounts of these nutrients in this section.
例中的通心粉奶酪含有大量这些物质
Highlighted in blue are the nutrients that you should aim to consume adequate amounts.
蓝色区域是你应该食用足量的物质
These are dietary fiber, vitamin A, vitamin C, calcium and iron.
它们是食用纤维，维生素A，维生素C，钙和铁
This example of macaroni and cheese is not a good source of dietary fiber,
例子中的通心粉奶酪不能提供足量食用纤维
as you can see there are zero grams of fiber in this product.
你可以看到此产品中含有的纤维量是0克
Understanding how to know if you are eating too much or too little of
一旦你了解了每日摄入量百分比
the nutrients mentioned is easier once you understand the percent daily value.
你就能更容易的理解如何知道自己是否摄入过多或过少的上述物质了
We will discuss the percent daily values just after the footnote section.
我们在介绍完补充说明一栏后就会讨论每日摄入量百分比

视频简介：

食物营养标签是什么？哪些食物应该贴有该标签？美国食药局规定大多数预加工食品，如各种面包，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。然而未加工产品如蔬菜水果鱼等则不必附有营养标签。营养标签的不同部分：食用分量，热量，两部分营养物质，补充说明和每日摄入百分比。本讲提供了一些对这些部分的简要说明。如何理解营养标签的这六个部分呢？食物分量、热量、营养成分，补充说明每日摄入百分比。
