一.菠菜:菠菜中含有大量草酸,草酸在人体内遇上钙便生成草酸钙,不易吸收。幼儿生长发育需要多量的钙,如果体内缺钙,可导致骨铬、牙齿等发育不良。二.浓茶:浓茶中含有大量鞣酸,鞣酸在人体内遇铁便生成鞣酸铁,难以被人体吸收,造成人体缺铁。幼儿缺铁不仅会发生贫血,而且还会影响智力发育。三.咸鱼:各种咸鱼都含有大量的二甲基亚硝酸盐,这种物质进入人体后,会转化为致癌性很强的二甲基亚硝胺。研究表明,在10岁前开始常吃咸鱼,成年后患癌症的危险性比一般人高30倍。四.糖精:研究表明,大量食用糖精会引起血液、心脏、肺脏、末稍神经疾病,损害胃、肾、胆、膀胱等脏器。因此,我国规定在病人和儿童食品中不得使用糖精。五.人参:目前市场上有不少人参食品,如人参糖果、人参麦乳精、人参奶粉、人参饼干以及人参蜂皇浆等。人参有促使性激素分泌的作用,幼儿食用人参会导致性早熟,严重影响身体正常发育。六.罐头:罐头食品在制作过程中都加入了一定量的食品添加剂,添加剂有微量毒性,对成人影响不大,而对发育不完全的幼儿确有很大影响。幼儿常吃罐头会损害健康,甚至会造成慢性中毒。
