Through this value, you can know more intuitively how much energy you consume, so as to ensure that the total energy of one day does not exceed the standard. no

Yes, so it's not too much, so it must be wrong. It should be viewed in light of its own situation.
Through its calculation formula, we can see its principle:
The calculation formula is:
X/NRV× 100% = Y %
Where: X = the content of a nutrient in food.
NRV = nutrient reference values of the nutrient.
Y% = calculation result
NRV% has a great influence on our health. If today's NRV energy is close to the maximum (i.e. 100%), we should control the calorie intake. Daily NRV data of protein, fat, saturated fat, carbohydrate and sodium also need to be calculated.
