1.？ According to the above recipes, calculate the daily energy and nutrient intake of the subjects? ：

2. Dietary energy and intake of various nutrients:

It can be seen from the data that the intake of energy, calcium and iron in protein is on the high side, and the intake of vitamins A, B 1 and C is deficient, especially vitamin C.

3.？ Energy supply ratio of three main nutrients:

Protein has a high energy supply ratio and a low carbohydrate energy supply ratio.

4, three meals energy distribution ratio:

Basically reasonable, the energy intake for dinner is slightly higher, and the energy intake for breakfast and lunch is slightly lower.

5. Proportion of high-quality protein:

The ratio of high-quality protein = (animal protein+bean protein)/total protein = (6+17.9+8.1+21.6)/83.7×100% = 64.0%, exceeding 30.0%.
