The levels of intake and food sources of zinc and copper in 231 20-80 yr old healthy adults living in Bangkok and surrounding districts were determined. Dietary data from 3-d food records collected and validated at Research Center, Ramathibodi Hospital were analyzed. Levels of zinc and copper intake were compared between sexes and age groups (20-39, 40-59, and 60-80 yr). Mean daily zinc and copper intakes (+/-SEM) in men were 6.3+/-0.2 and 1.9+/-0.1 mg, respectively. Mean daily zinc and copper intakes (+/-SEM) estimated in women (5.5+/-0.2 and 1.6+/-0.1 mg) were significantly lower. Higher zinc and copper intakes were found in the younger (20-39 yr) age group of both sexes. This could be explained by higher density and percentage from animal source of both nutrients. Consumption of various types of meat, fish, egg, and milk accounted for 42 and 22%, and rice, the staple food of Thai people for 9 and 23% of total dietary zinc and copper, respectively.
测定了居住在曼谷及其周边地区的231名20至80岁健康成年人的锌和铜摄入量水平及食物来源。对在拉玛蒂博迪医院研究中心收集并验证的3天食物记录中的饮食数据进行了分析。比较了不同性别和年龄组（20 - 39岁、40 - 59岁和60 - 80岁）的锌和铜摄入量水平。男性的每日锌和铜平均摄入量（±标准误）分别为6.3±0.2毫克和1.9±0.1毫克。女性的每日锌和铜平均摄入量（±标准误）估计值（5.5±0.2毫克和1.6±0.1毫克）显著较低。在两个性别的较年轻（20 - 39岁）年龄组中发现锌和铜摄入量较高。这可以通过这两种营养素来自动物来源的更高密度和百分比来解释。各类肉类、鱼类、蛋类和奶类的消费量分别占膳食锌和铜总量的42%和22%，而泰国人的主食大米分别占9%和23%。
