Nutrition label in the USAThe United States also uses percent daily values in their required nutrition labels.
In the US the Percent Daily Values is presented on the Nutrition Facts panel, as is done in Canada, and communicates the key summary information consumers need to make informed dietary choices.
In the U.S., the % Daily Values (%DVs) are based on the Daily Value recommendations for key nutrients for a 2,000 calorie daily diet.
Consumers are encouraged to use the %DV as a frame of reference - whether or not they consume more or less than the 2,000 calorie guideline. The %DV helps consumers determine if a serving of food is high or low in a nutrient.
Consumers can tell high from low and know which nutrients contribute a lot, or a little, to their daily recommended allowance.
The Nutrition Facts label was mandated for most food products under the provisions of the 1990 Nutrition Labeling and Education

In addition to the Nutrition Facts panel information, America’s leading food and beverage manufacturers and retailers announced on 24 January 2011 the launch of Nutrition Keys, a new voluntary front of pack nutrition labeling system that will help busy consumers make informed choices when they shop. The program represents the most significant modernization of food labels since the Nutrition Labeling and Education Act of 1990.
The Nutrition Keys program was developed in response to a request from First Lady Michelle Obama in March of last year. She is working on projects to significantly reduce childhood obesity.
