(2) protein content of chicken leg (80g) is 21.5 ÷100× 80 =17.2g, fat content is 2.5÷ 100×80=2g, and carbohydrate content is 0.7 \.

(3) protein content of braised pork trotters (120g): 21.5 ÷100×120 = 25.8g, and fat content: 2.5 ÷100×.

(4) Penaeus monodon (100g) contains protein17.6g, 0.8g of fat and 0.2g of fat; Carbohydrate;

(5) Rice (50g) Rice: protein content: 6.7÷2=3.35g, fat content: 0.7÷2=0.35g, carbohydrate: 77.9÷2=38.95g,

Therefore, in the above foods, the protein content is10.05+17.2+25.8+17.6+3.35 = 64g, and the fat content is 5.1+2+3+0.8+0.35 =.

Protein content; 64 > 30, fat content: 1 1.25 < 23, carbohydrate: 40.6 < 120,

A: Xiaoming's nutrition is unreasonable, which is quite different from the nutrition standard. It can be matched according to one meat, one vegetable and one staple food per person.

So the answer is:
