随着检测手段的不断提高,现在已证实人体内存在的微量元素达41种之多,且绝大多数为金属元素,又称“金属酶”。本文主要介绍几种必需微量元素对人体健康的影响。 1 锌(Zn) 人体内至少有80余种酶中含锌。导致体内缺锌的主要原因为:①供给不足,主要是食物中含锌不足。②丢失过多,如钩虫病、血吸虫病及疟疾等。③吸收不良,如食物中含植物酸盐和纤维素过多、胰腺纤维囊性化、脂肪泻等均可造成锌吸收不良。 锌缺乏时,在临床上早期即可出现味觉减退、食欲低下及异食癖;多有贫血;重症者可表现为精神萎靡、生长停滞、性发育延迟、伤口愈合延迟甚至出现肢皮类
With the continuous improvement of testing methods, it has been confirmed that there are 41 kinds of trace elements present in the human body, and the vast majority of metal elements, also known as “metalloenzyme.” This article describes the effects of several essential trace elements on human health. 1 zinc (Zn) in the body at least 80 kinds of enzymes containing zinc. Lead to the body of zinc deficiency are the main reasons: ① lack of supply, mainly lack of zinc in food. ② lost too much, such as hookworm disease, schistosomiasis and malaria. ③ malabsorption, such as food containing too much salt and cellulose plant, pancreatic fiber cystic, steatorrhea, etc. can cause zinc malabsorption. Zinc deficiency, early in the clinical symptoms of diminished taste, loss of appetite and pica; more anemia; severe cases can be manifested as apathetic, stunted growth, delayed sexual development, delayed wound healing or even appear
