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
But the total energy of most foods is calculated according to the energy required by light manual workers (2000 kcal -2 100 kcal).
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%), I will
Children should control their calorie intake. Daily NRV data of protein, fat, saturated fat, carbohydrate and sodium also need to be calculated.
Count.
The most critical value in the nutrient composition table is "NRV%", that is, a certain nutrient in each unit of food (100g or 100ml or 1 serving of food).
Percentage of nutrient reference values Required Daily (NRV). This value is calculated by nutritionists according to the nutrients of China residents.
Recommended intake.
For example, if the "NRV%" of sodium in100g of a certain food is 2 1%, it means that the100g of this food can be provided to adults for about one day.
2 1% sodium requirement. We can scientifically match foods according to the "NRV%" values of various nutrients to maintain a balanced nutrition.
