The DV, also called the Daily Value, is the amount of a nutrient (total fat, fiber, protein, calcium, and so on) that adults should consume daily to remain healthy, based on values set up by the Food and Drug Administration (FDA).
The % DV on food labels is the amount of nutrient provided by one serving of the food compared with the amount of nutrient recommended for adults each day. Check % DV on the nutrition labels of foods you eat. Then add up the percentages you have consumed over a day and see how close you come to 100%. Keep in mind that the standards used on Nutrition Facts panels are based on a daily 2,000 calorie diet for adults—so amounts will be different for children.
