The uptake of iron, zinc, copper and lead by food cooked under domestic conditions in utensils made of different metals (cast iron, aluminium, plain and tinned copper) was investigated. It was found that the metal content of the food was generally related to the metal in immediate contact with the food during cooking. Daily dietary intake could vary from 11 to 6 mg of iron, 11 to 9 mg of zinc, 2 to 1 mg of copper and 0.4 to 0.1 mg of lead, depending on the cooking utensils used. Dietary intake of the metals was also related to sources and domestic practices regarding water supply. Consistent use of municipal water from a domestic hot water system could contribute a daily intake of 32 mg iron, 29 mg zinc and 12 mg copper. Rainwater stored in a galvanized iron tank could provide 23 mg of zinc per day when used for domestic purposes. The nutritional and toxicological significance of such adventitious sources of metals in the diet are discussed. The need to consider them when investigating the metal intake of individuals is stressed.
研究了在家庭条件下，使用不同金属（铸铁、铝、普通铜和镀锡铜）制成的炊具烹饪食物时，铁、锌、铜和铅的摄入量。结果发现，食物中的金属含量通常与烹饪过程中与食物直接接触的金属有关。根据所使用的炊具不同，每日膳食摄入量可能在铁11至6毫克、锌11至9毫克、铜2至1毫克、铅0.4至0.1毫克之间变化。金属的膳食摄入量还与水源和家庭供水习惯有关。持续使用家庭热水系统中的市政水，每天可能摄入32毫克铁、29毫克锌和12毫克铜。储存在镀锌铁罐中的雨水用于家庭用途时，每天可提供23毫克锌。文中讨论了饮食中这些偶然的金属来源的营养和毒理学意义。强调了在调查个体金属摄入量时需要考虑这些因素。
