锌是人体重要的微量元素之一,人体微量元素中锌的含量仅次于铁。锌在人体内被融合在蛋白质、核酸、细胞膜之中,尤其是人体内100多种酶都含有锌,称之为含锌酶。含锌酶是人体代谢的重要物质,因此锌与人体许多生理功能有关:含锌酶是氨基酸代谢及蛋白质合成的物质,缺锌后可致蛋白质合成减少,从而影响细胞分裂增殖;锌能促进生长发育,尤其对生长发育迅速的儿童、少年和青年至关重要;锌和维生素A的代谢关系密切,缺锌后维生素A的体内合成减少导致维生素A缺乏;锌与细胞膜蛋白结合使细胞膜稳定,缺锌后体内细胞膜遭受体内氧自由基攻击的可能性增加,从而引起细胞膜稳定性下降和细胞损毁增加;锌参与免疫功能,对免疫功能具有营养和调节作用,故缺锌后可致细胞免疫功能下降,身体抵抗能力减弱。锌可提升胸腺释放胸腺素,改进或提升T淋巴细胞的攻击、歼灭病源微生物的行动,从而使机体少染多种“感染性疾病”。膳食搭配不当,营养素不全,经久泄泻、呕吐、不运动或运动量不足者均应纳入“缺锌”群体。对那些“饭来张口、衣来伸手”有人扶持的居家老人更应关注补锌。

补锌主要是通过饮食补充,食物中含锌量多的食物有牡蛎、鱼子、动物肝、肾、花生、蛋黄及坚果类,只要平时多吃一点上述食物,人体就不会发生缺锌现象,即使已经缺锌,也会很快补上。

所以当孩子缺锌的时候,家长要及时给孩子补点锌来增强免疫力哦。佰佰安全网关于儿童健康饮食以及增强宝宝免疫力的保健品有哪些这方面的常识正在更新当中,如果您有兴趣,可以持续关注哦。
