You will find this label on most foods.

The Nutrition Facts label allows you to compare similar foods or to check whether the food is a good source of a nutrient. The % Daily Value section can tell you whether a food is high or low in a particular nutrient. If you want to limit a certain nutrient (such as saturated fat or sodium), choose foods with a lower % Daily Value.

Serving sizes of similar foods are the same on all Nutrition Facts labels, to make comparing foods easier. There may be more than 1 serving in each container. This can make a difference when you are watching your calories and nutrients. *The % Daily Value is based on 2,000 calories a day. You may need more or less than 2,000 calories a day. You can see how many calories you need each day at www.choosemyplate.gov.
