First when reading any food label you should start by noticing the serving size given.
閱讀食物標簽時我們首先注意到的是提供的食用分量
There are two different parts in this section
它包含兩個不同的部分
the serving size and then the number of servings per container.
食用分量和使用分量的數量
The serving sizes are usually listed in standard measurements such as cups pieces tablespoons etcetera.
食用分量通常以標準尺度列出如杯，塊，匙等等
The serving size allows you to compare similar food products to each other.
食用分量可以使你比較相似的產品
After noticing the serving size you should also look to
關注完食用分量你還應該關注
see how many serving sizes are within the container
每包產品含有多少個食用分量
this information is listed just below the serving size.
這一項就列在食用分量之下
If you consume the whole package of food
如果食用了整包食品
you will have to multiply the number of servings per container by all the information listed on the box.
那就得把整包食品的食用分量數乘以標簽上的所有數據
Using this macaroni and cheese food label as an example.
以通心粉奶酪的食物標簽為例
The serving size is one cup.
其食用分量是一杯
Below this it reads servings per container two.
下面是每盒含有兩小包
This means if you were to eat the whole box of macaroni and cheese
也就是說如果你吃了一整盒通心粉奶酪
you would eat a total of two cups of macaroni and cheese.
相當于吃掉了兩杯通心粉奶酪
Also if you eat the whole box
同理，如果你吃掉了一盒，
you would then need to multiply the rest of the numbers on the food label
你需要將食品標簽上的其他數據
by the number two as well as to figure your calories consumed and the total nutrients consumed.
乘以2來獲知自己食入的總熱量和所有營養物質
Moving on, the next section of the food label is calories.
繼續看食物標簽的下一部分是熱量
Calories also have two pieces of information listed on the food label.
它也有兩欄信息列在食物標簽上
Calories per serving tell you the amount of energy in each serving.
每份熱量告訴你每份食品中含的熱量
Located just to the right of calories per serving a food label will list calories from fat.
位于其右側的是來自脂肪的熱量
Both of these are important in order to figure the total amount of calories you consume,
這兩個數據都很重要，要計算自己食用的熱量總量
you must multiply the calories per serving by the number of servings that you have consumed.
你得將每份含有熱量與食用的份數相乘
Calories from fat tells the consumer how many of the total calories consumed are coming from fat.
來自脂肪的熱量告知消費者攝入的總熱量中來自脂肪的部分
This information will allow you to
這部分信息可以使你
compare the calories from fat to the number of calories in each serving.
比較來自脂肪的熱量與每份含有的熱量
This number can be calculated by dividing the number of calories from fat by the number of calories per serving.
這一數據可以用脂肪提供的熱量與每份含有的熱量之比來表示
As you can see here listed just below the serving size is information about calories.
現在你在這里看到的食用分量之下的就是熱量信息
On the left it shows the calories per serving are 250 and on the right it shows calories from fat 110.
左側顯示每份含有熱量為250卡，右側顯示脂肪提供110卡熱量
This means that there are 110 calories per serving coming from fat
這就是說每袋脂肪提供110卡熱量
as compared to the total amount of calories per serving being 250.
而每袋總熱量是250卡
To calculate the percentage of calories from fat you can divide 110 by 250 which equals 44%.
要算出每袋脂肪提供熱量比例，就用110除以250得到44%
So if you are eating one serving of macaroni and cheese you would consume a total of 250 calories,
因此，如果你吃了一袋通心粉奶酪，就攝入了250卡熱量
110 of those calories are coming from fat which means that 44% of your total calories consumed are from fat.
其中的110卡來自脂肪，也就是說攝入總熱量的44%來自脂肪
If you eat the whole box of macaroni and cheese
如果你吃掉了整盒通心粉奶酪
you would consume a total of 500 calories which is 250 multiplied by 2 servings and this would be 220 calories coming from fat.
就共攝入了500卡熱量，由250乘以2獲得，其中220卡來自脂肪
