Which standards used on food labels people determine the nutrient content of foods within their overall diet?

The Percent Daily Value (%DV) is a food label indicator that determines the daily value recommendations of the key nutrients in the food package.

The %DV helps in knowing if the food serving is high or low in its nutrient levels.

Since the serving size is almost the same for different brands of the same kind of food package, customers can use the %DV information for comparison and choose the better option.
