通过原子吸收光谱法测定，医院饮食中铜和锌的平均每日含量分别为0.76和9.4毫克。这些饮食与公布的数据比较显示，铜和锌的每日中位数分别为0.78和12.0毫克，从传统食品制成的20饮食。这些铜和锌的含量低于成人每天所需的2毫克铜和13毫克锌。医院的饮食，也许一般的饮食似乎是低的铜和锌;铜的量低于锌的量与各自的需求相比。这些元素的常见饮食量可能会导致健康问题。
The mean daily amounts of copper and zinc found in hospital diets by atomic absorption spectrometry were 0.76 and 9.4 mg, respectively. Comparison of these diets with published data showed median daily amounts of copper and zinc to be 0.78 and 12.0 mg, respectively, for 20 diets made from conventional foods. These amounts of copper and zinc are less than the 2 mg of copper and 13 mg of zinc thought to be required daily by adults. Hospital diets and perhaps diets in general seem to be low in copper and zinc; the amounts of copper are lower than those of zinc in comparison with respective requirements. Common dietary amounts of these elements may cause health problems.
