选项
答案
解析 1．能量：平均每人需要量标准＝(2400+2100)/2＝2250kcal
实际摄入能量＝300g/100g×346＋100g/100g×344＋50g/100g×140＋75g/100g×144×0.88＋300g/100g×24×0.89＋100g/100g×43×0.97＋50g/100g×87＋50g/100g×143+30g/100g×899
＝1038＋344＋70＋95＋64＋42＋44＋72＋270＝2039kcal
2．蛋白质：平均每人需要量标准：（75＋65）/2＝70g
实际摄入量＝300g/100g×7.4＋100g/100g×11.2＋50g/100g×16.2＋75g/100g×13.3×0.88＋300g/100g×2.6×0.89＋100g/100g×1.4×0.97＋50g/100g×16.4＋50g/100g×20.3+30g/100g×0
=22.2+11.2+8.1+8.8+6.9+1.4+8.2+10=76.8g
3．脂肪：平均每人需要量标准：2250kcal×20％＝450kcal
450kcal/9=50g
实际摄入量＝300g/100g×0.8＋100g/100g×1.5＋50g/100g×3.6＋75g/100g×8.8×0.88＋300g/100g×0.3×0.89＋100g/100g×0.2×0.97＋50g/100g×2.4＋50g/100g×6.2+30g/100g×99.9
＝2.4+1.5+1.8+5.8+0.8+0.2+1.3+3.1+30
＝46.9g
4．钙：平均每人需要量标准：800mg
实际摄入量
＝300g/100g×13＋100g/100g×31＋50g/100g×308＋75g/100g×56×0.88＋300g/100g×66×0.89＋100g/100g×32×0.97＋50g/100g×6＋50g/100g×13+30g/100g×0
＝39+31+104+37+176+31+3+6.5＝427.5mg
5．铁：平均每人需要量标准：（15＋20）/2=17.5mg
实际摄入量
＝300g/100g×2.3＋100g/100g×3.5＋50g/100g×4.9＋75g/100g×2×0.88＋300g/100g×2.9×0.89＋100g/100g×0.5×0.97＋50g/100g×3＋50g/100g×2+30g/100g×0
＝6.9+3.5+2.45+1.32+7.74+0.49+1.5+1＝24.9mg
6．维生素A：平均每人需要量标准：（800＋700）/2=750ugRE
实际摄入量
＝300g/100g×0＋100g/100g×0＋50g/100g×0＋75g/100g×234×0.88＋300g/100g×487×0.89＋100g/100g×668×0.97＋50g/100g×44＋50g/100g×0+30g/100g×0
＝154.4+1300.3+648+22＝2124.7ugRE
7．维生素B1：平均每人需要量标准：（1.4＋1.3）/2=1.35mg
实际摄入量＝300g/100g×0.11＋100g/100g×0.28＋50g/100g×0.03＋75g/100g×0.11×0.88＋300g/100g×0.04×0.89＋100g/100g×0.04×0.97＋50g/100g×0.54＋50g/100g×0+30g/100g×0＝0.33+0.28+0.015+0.07+0.11+0.04+0.27＝1.12mg
8．维生素B2：平均每人需要量标准：（1.4＋1.2）/2=1.3mg
实际摄入量＝300g/100g×0.05＋100g/100g×0.08＋50g/100g×0.07＋75g/100g×0.27×0.88＋300g/100g×0.11×0.89＋100g/100g×0.04×0.97＋50g/100g×0.1＋50g/100g×0+30g/100g×0＝0.15+0.08+0.035+0.18+0.29+0.04+0.05＝0.825mg
9．维生素C：平均每人需要量标准：100mg
实际摄入量＝300g/100g×0＋100g/100g×0＋50g/100g×0＋75g/100g×0×0.88＋300g/100g×32×0.89＋100g/100g×16×0.97＋50g/100g×0＋50g/100g×0+30g/100g×0
＝85.4+15.5＝100.9mg
