This is easy to understand, and the table of nutrients is easy to understand. In the last column of NRV%, there may be quite a few people who don’t understand its meaning.
NRV% tells consumers the ratio of a nutrient or energy per 100 grams or serving (××g) to the daily demand, such as a food package labeled The 100 grams of protein provided by this food is 6.7 grams, and the NRV% is 11%. Then the protein that can be given to this person by eating 100 grams of this food is 11% of his daily intake.
The reference intake data should be derived from the “Chinese Dietary Nutrient Reference Intake” recommended by the Chinese Nutrition Society. In addition to infant food, the reference intake of nutrients in prepackaged foods is based on the daily intake of adults with light physical activity.
How to choose food based on food nutrition label?

If the protein is only a few tenths or 1.0, it is a milky beverage or milk beverage. , not milk; when buying confectionery, look at total energy or total fat, trans fatty acid and sodium. Buying meat or buying cooked meat products requires attention to fat and sodium.
2. According to the physical condition of the consumer or the target of the consumer, such as hypertensive patients, special attention should be paid to the sodium content. If the sodium content of the purchased food is 2300 mg per 100 g, eat 100 g. This kind of food reaches 6 grams of salt per day recommended for a balanced diet. This food is not suitable for patients with hypertension, and people who lose weight need to pay attention to energy values and so on.
