The zinc is one of basic essential trace-elements in human nutrition. The problem of the determination of zinc requirements in man is discussed in view of an appearance of adaptation to various levels of this trace element in a diet and degree of its bioavailability in basic kinds of foodstuff. The problem of evaluation of zinc bioavailability is highlighted from the positions of zinc absorption mechanisms based on the research data which have been obtained in model systems and in vivo in human and laboratory animals.
锌是人类营养中基本的必需微量元素之一。鉴于人体对饮食中不同水平的这种微量元素的适应情况以及其在各类基本食物中的生物利用度，本文讨论了确定人体锌需求量的问题。基于在模型系统以及人体和实验动物体内所获得的研究数据，从锌吸收机制的角度突出了评估锌生物利用度的问题。
