在日常生活中,人们往往认为,现在经济条件好,又是独生子女,应多食肉、蛋、奶,摄取的动物蛋白越多,营养价值就越高。这种看法是片面的,如何衡量蛋白质的营养价值呢?主要看食物蛋白质中必需氨基酸的含量是否齐全,配比是否恰当,以及消化率的高低来决定的。当食物蛋白质中某种氨基酸含量过高或过低造成氨基酸的不平衡,都可以降低氨基酸的利用率。所以,现在独生子女虽然条件好,自认为吃得好(肉、蛋、奶),但由于有偏食、挑食的坏习惯,虽 In daily life, people often think that now that economic conditions are good and they are only children, they should eat more meat, eggs and milk. The more animal protein they consume, the higher the nutritional value. This view is one-sided, how to measure the nutritional value of protein? Mainly look at the content of essential amino acids in food protein is complete, the ratio is appropriate, and the level of digestion to decide. When an amino acid content in food protein is too high or too low, the amino acid imbalance can reduce the utilization of amino acids. Therefore, although the only child now has good conditions and considers himself well eaten (meat, eggs and milk), due to the bad habits of partial eclipse and picky eaters,
