Final answer:
Food labels reference Daily Values on nutrition facts labels, indicating how much of each nutrient is in a serving of food relative to a recommended daily diet.
Step-by-step explanation:
Food labels express the nutrient content in relation to a set of standard values known as the Daily Values (DV). These values are referenced on nutrition facts labels on packaged foods to help consumers understand the nutrient content in the context of their total daily diet. The percent daily values (% DV) listed on food labels indicate how much a nutrient in a serving of food contributes to a daily diet, with the general advice being that if a nutrient has a DV of 5% or less, it is low in that nutrient, and if it has a DV of 20% or more, it is high.
