A total of 51 athletes, randomly divided into two groups (with or without zinc supplementation) and respective two subgroups (with or without cereal diet) had been tested for their serum levels in respect of zinc, iron, copper, phosphorus and potassium over a period of 8 weeks, i.e. during a period of competition. Furthermore, subpopulations of lymphocytes were defined. Modifications of the immunologic defense mechanism with special regard to the zinc level could, however, not be detected. Minerals, i.e. zinc and iron revealed to decrease significantly during simultaneous uptake of certain amounts of the cereal products. This is due to the relatively high amounts of phytates in cereals which are capable to bind the trace elements in form of complex salts.
共有51名运动员，随机分为两组（补锌组和不补锌组），每组又各自分为两个亚组（谷类饮食组和非谷类饮食组），在为期8周的比赛期间对他们的血清锌、铁、铜、磷和钾水平进行了检测。此外，还对淋巴细胞亚群进行了定义。然而，未检测到免疫防御机制随锌水平的变化。矿物质，即锌和铁，在同时摄入一定量谷类产品时显著减少。这是由于谷类中含有相对大量的植酸盐，能够以络合盐的形式结合微量元素。
