The dietary intake of copper, chromium, and zinc from foods in Tarragona Province (NE Spain) was determined by means of two different methods: the total diet study and the duplicate diet study. In the total diet study, a total of 375 food samples were analyzed, whereas duplicates of food consumed weekly by 20 families were analyzed for copper, chromium and zinc concentrations. Pulses were the group with the highest levels of the three elements; vegetables and fruits which are basic items in the 'Mediterranean diet', contained low concentrations of these metals. Total intakes of copper, chromium and zinc were 1156.3, 124.6 and 7522.9 micrograms day-1, respectively. On the other hand, the total intake of the elements obtained through the duplicate diet study was 1119.8 micrograms day-1 for copper, 129.0 micrograms day-1 for chromium, and 6800.1 micrograms day-1 for zinc. The daily intake of copper and zinc by the population of Tarragona Province is lower than the usually recommended values, while the intake of chromium is closer to those values.
通过两种不同方法测定了西班牙东北部塔拉戈纳省食物中铜、铬和锌的膳食摄入量：总膳食研究法和双份膳食研究法。在总膳食研究中，共分析了375份食物样本，同时对20个家庭每周食用的食物复制品进行了铜、铬和锌浓度分析。豆类是这三种元素含量最高的食物类别；作为“地中海饮食”基本组成部分的蔬菜和水果，这些金属的含量较低。铜、铬和锌的总摄入量分别为每日1156.3微克、124.6微克和7522.9微克。另一方面，通过双份膳食研究得出的这些元素的总摄入量为：铜每日1119.8微克、铬每日129.0微克、锌每日6800.1微克。塔拉戈纳省居民铜和锌的每日摄入量低于通常推荐值，而铬的摄入量更接近这些值。
