锌是人体内重要的微量元素,尤其对婴幼儿来说,锌缺乏将会影响今后的生长、智力发育和免疫功能。缺锌的原因孩子生长发育快,所需要的锌较成人相对多,如果有挑食习惯,不喜欢吃富含蛋白质的蛋、肉类食物,就易缺锌。营养不良和长期腹泻可使锌吸收减少。外伤、失血、尿毒症等也会使锌排出增多。人工喂养的宝宝也会缺锌,因为牛奶中的锌吸收利用率均不及母乳。 Zinc is an important trace element in the human body, especially for infants and young children, zinc deficiency will affect future growth, intellectual development and immune function.
