中小学是人生历程中的重要阶段,它不仅是长知识的时期,同时也是长身体的时期,实践证明,没有健康的身体就难以胜任这个最基本的学习。要有健康的身体不仅需要锻炼,更需要合理营养。根据1982年我国营养调查资料表明,中、小学生营养素食量占供给量的百分比明显低于全国人群的平均数,例如能量在中小学生中分别为99.1%、91.5%,而全国平均为102.2%。蛋白质为81.6%、87.1%和92.2%,钙为64.5%、49.9%和71.1%、维生素A为5.3
Primary and secondary schools are an important stage in their journey of life. They are not only a period of long knowledge, but also a long period of time. Practice has proved that it is difficult to qualify for this most basic study without a healthy body. To have a healthy body requires not only exercise, but also need rational nutrition. According to the 1982 China Nutrition Survey data, the percentage of primary and secondary school students serving nutrients in the total supply was significantly lower than the national average. For example, energy was 99.1% and 91.5% of primary and secondary students, respectively, while the national average was 102.2%. Proteins were 81.6%, 87.1% and 92.2%, calcium was 64.5%, 49.9% and 71.1%, and vitamin A was 5.3
