There are two sets of reference values for nutrients in nutrition labeling, Daily Reference Values (DRVs) and Reference Daily Intakes (RDIs). The DRVs are established for macronutrients, fat, saturated fat, total carbohydrate (including fiber), protein, cholesterol, sodium, and potassium. The RDIs are established for micronutrients, such as vitamins.

For clarity and simplicity on the label, the DRVs and RDI are combined in designation by a single term, the Daily Value (DV). Specifically, the Nutrition Facts includes the % DV.

Declaring nutrients as a percentage of the Daily Values is intended to prevent misinterpretations that arise with quantitative values. For example, a food with 140 mg of sodium could be mistaken for a high‐sodium food because 140 is a comparatively large number. In actuality, however, 140 mg represents about 6 percent of the Daily Value for sodium, which is 2,300 mg. On the other hand, a food with 5 grams of saturated fat could be construed as being low in that nutrient. In fact, that food would provide one‐fourth the total DV because 20 grams is the DV for saturated fat.
