锌是人体内必需微量元素,它是体内多种酶的组成成分,这些酶主要参与机体的能量代谢,核酸代谢及免疫功能。当人体缺锌时,含锌酶的活力下降,随之出现锌缺乏症状。人体每日锌的需要量约为2.2毫克,如按混合膳食中平均吸收率20％估计,则每人每日供给量应为11—13毫克。为了了解武汉市常用食物中锌含量,我们选择了二十种食品,测定含锌量,并同时对89例12—13岁青少年测了发锌值与血清锌含量,今将结果报
Zinc is an essential trace element in the human body and is a component of various enzymes in the body. These enzymes are mainly involved in the body’s energy metabolism, nucleic acid metabolism and immune function. When the human body is deficient in zinc, the vitality of the zinc-containing enzyme is reduced, with consequent symptoms of zinc deficiency. The body needs about 2.2 milligrams of zinc a day, as estimated by the average absorption rate of 20% in a mixed diet, and the daily supply should be 11-13 milligrams per person. In order to understand the commonly used foods in Wuhan City, zinc content, we have selected 20 kinds of food, determination of zinc content, and 89 cases of adolescents aged 12-13 measured hair zinc and serum zinc content, the results will now be reported
