Labels on food produce in the United States are required and supervised by the United States Food and Drug Administration. The purpose of the labels is to insure that consumers have the information they need to make informed decisions about the food items they purchase and consume.
Label information explains the nutritional value of the food item by listing the percentage of the Daily Recommended Allowance of specific nutrients that would be consumed in one serving of the item. The amount of the food that is considered to be one serving and the number of calories in one serving is also defined.
In the case of fresh produce, such as fruits and vegetables, the list of ingredients in the food item is short. If the food item has been processed or combined with other ingredients, the ingredients included in the food item would also be listed on the label.
