补锌的定义和作用;

补锌是补充人体必需的微量元素锌,锌在人体生长发育、生殖遗传、免疫、内分泌等重要生理过程中起着极其重要的作用。

锌存在于许多酶系统中,如碳酸酐酶、呼吸酶、乳酸脱氢酶、超氧化物歧化酶、碱性磷酸酶、DNA和RNA聚合酶等。它是合成核酸、蛋白质、碳水化合物和利用维生素A的必需物质..具有促进生长和改善口感的作用。

缺锌容易出现味觉和嗅觉差,厌食,生长缓慢,智力发育低于正常。补锌可以常吃富含锌的食物:如蛋白锌、牡蛎、核桃、蛋黄、海鲜等。

含锌食物:

瘦牛肉、猪肉、羊肉、鸡心、鱼、牡蛎、蛋黄、脱脂奶粉、小麦胚芽、芝麻、核桃、豆类、花生、小米、萝卜。

锌主要存在于海产品和动物内脏中,其他食物中锌的含量很少——儿童爱吃的水、主食和鸡蛋中几乎没有锌,含锌的蔬菜和水果也不多。

瘦肉、猪肝、鱼、蛋黄含锌,其中牡蛎含锌最高。据实验室检测,动物性食物一般含锌量较高,每100克动物性食物中含锌量约为3-5毫克,动物蛋白分解后产生的氨基酸也能促进锌的吸收。

植物性食物中锌含量较少。每100克植物性食物中含有约65438±0毫克的锌。各种植物性食物中含锌量较高的有豆类、花生、小米、萝卜、大白菜等。

每100克食物中的锌含量约为:

1,瘦肉3.8毫克;

2、猪肝4毫克;

3、鸡肝5毫克;

4、蛋黄3.4毫克;

5、海带3.2毫克;

6、鱼虾8毫克。
