(1) For the convenience of calculation, protein accounts for 15% of energy, 60% of carbohydrate and 25% of fat.

Then: protein intake: 2200* 15%/4kcal/g=82.5g, carbohydrate intake: 2200*60%/4kcal/g=330g, fat intake: 2200 * 25%/4kcal/g =/kloc-0.

(2) 330g * 40% =132g, 330g *30%=

99g, 330*40%= 132g, rice intake = 132g/77.2%= 170g.

Flour intake: 99/74.6%= 132g.

Corn intake: 132g/66.6%= 198g.

(According to the food composition table, the amount of car in rice accounts for 77.2%, flour for 74.6% and corn for 66.6%. )
