what is the reference value for the intake of nutrients used on the food label?

The reference values for nutrient intake used on food labels are typically based on established dietary guidelines, such as the Daily Values (DVs) set by health authorities like the FDA. These values indicate the recommended daily intake of various nutrients for a standard adult diet, often based on a 2,000-calorie daily intake. DVs help consumers understand the nutritional content of food in the context of their overall daily diet. Specific values can vary by nutrient and demographic factors, such as age and sex.
