小儿的生长发育十分迅速,一年内体重增加可达出生时的3倍。3岁时可达13千克,6岁的孩子一般可长到20公斤左右。每增加1千克体重。约需增加血液80～100毫升.如此迅速的生长速度,必须有大量的造血原料来满足生长发育的需要。可偏偏在这段十分关健的时间里,由于人们对营养学的认识不足,常常以含造血原料较少的牛乳、巧克力、麦乳精、各种糖果点心来做为孩子的主要辅助食品.结果使这个年龄的儿童营养性贫血的发生率较高。就连上海这样的大城市,3岁以内的小儿也有50%左右发生不同程度的营养性贫血。
Children’s growth and development is very rapid, within a year of weight gain up to 3 times the birth. 3 kilograms up to 13 kg, 6-year-old children can generally grow to about 20 kg. Each additional weight of 1 kg. About to increase the blood 80 to 100 ml.Such rapid growth rate, there must be a lot of hematopoietic raw materials to meet the needs of growth and development. However, during this very crucial time, people often do not have sufficient knowledge of nutrition, and often use milk, chocolate, wheat milk essence and various confectionary desserts, which contain less raw materials for blood, as the main supplementary food for their children. As a result, children of this age have a higher incidence of nutritional anemia. Even in a big city like Shanghai, about 3% of infants under 3 years old have varying degrees of nutritional anemia.
