# What does the nutrient reference value in the nutritional composition table mean?

Update:19-05-2020

There is a nutrient composition table on the outer packaging of general food. Most people may not know what they mean. The following is an introduction for everyone:

When reading the nutrition table, don't assume that the value in it is the whole package. Usually the nutrition table is marked in units of 100g or 100ml, but there are also units according to the whole package and each packet. As for the following "nutrient reference value%", in simple terms, the country gives a "recommended daily dietary amount" for caloric value and each nutrient. "Nutrient reference value%" refers to the nutrient content accounted for each What is the percentage of the reference value of nutrients recommended for the daily diet, that is, "nutrient reference value%" in the nutrient composition table = "the content of the substance per serving / nutrient reference value", the reference value of nutrients in China is as follows:

Then let's calculate a nutrient reference ratio: for every 100 kr, the energy value is 2325kJ, and the energy in the nutrient reference value table is 8400kJ, then the energy "nutrient reference value%" = 2325kJ / 8400kJ = 0.276≈28% "Nutrient reference value%" of protein = 36.9 g / 60 g = 0.615≈62%; "Nutrient reference value%" of fat = 43.1 g / 60 g = 0.718≈72%; "Nutrient reference value%" of carbohydrate = 3.8 g / 300 g = 0.012≈1%; the “nutrient reference value%” of sodium = 244 mg / 2000 mg = 0.122≈12%. Some products have more nutrients in the nutrient composition table, and their nutrient reference value (NRV)% is also calculated according to the above method.
