Daily Reference Values. Recommended daily amounts set by the FDA for macronutrients - total fat, saturated fat, cholesterol, total carbohydrates, dietary fiber, sodium, potassium and protein. DRV's are based on current nutrition recomendations for a 2,000 calorie diet. They apply to anyone age four and older. The DRV for sodium, for example, is 2,400 milligrams, whether you are aged four, forty-four or one-hundred four
The second set of numbers you find on the food label are for nutrients and food components that traditionally do not have an RDA, such as fat and fiber, but that do have an important relationship with health. These values are referred to as Daily Reference Values (DRVs).
