我国人民素以谷类粮食为主食,谷类蛋白质含量一般较低,氨基酸组成不够平衡。据最近调查,我国人均日摄入热量已达到人体所需的2400大卡,而蛋白质的摄入量只有62.7克,距人体所需的70克尚差7.3克。其所摄入的蛋白质中,88%来源于植物蛋白,动物蛋白仅占12%。据联合国粮农组织的统计,1977年全世界人均可获得蛋白质为64.7克/人·天。其中动物蛋白为24.5/人·天。可见,我国目前的营养水平还低于1977年的世界平均值。为改变这一状况,我
The people of our country are mainly cereal grains, cereal protein content is generally low, amino acid composition is not balanced. According to a recent survey, China’s per capita daily intake of calories has reached the body’s 2,400 kilocalories, while the protein intake of only 62.7 grams, 70 grams from the body is still poor 7.3 grams. 88% of its ingested protein is derived from plant protein, and animal protein accounts for only 12%. According to the UN Food and Agriculture Organization, in 1977, the world’s per capita available protein was 64.7 g / person / day. Animal protein was 24.5 / person day. Can be seen that our current level of nutrition is also lower than the world average in 1977. To change this situation, I
