題目是:年輕男子長期攝取高銅飲食之材料和方法的部分文

The subjects were confined in the metabolic research unit (MRU) of the Western Human Nutrition Research Center for the first 18 d followed by a 129-d free-living period and the second 18 d in the MRU.

They were fed diets containing 1.6 mg of copper (as copper sulfate) per day during the first 18-d period and were given copper supplements (7 mg of copper per day) with their regular diets for 129 d. After this period, they returned to the MRU for the second 18-d period and were fed the diets supplemented with copper (6.2 mg/d), resulting in a total copper intake of 7.8 mg/d.

This dose is approximately the amount of copper that would be ingested if a person consumed a normal diet and two or three commercially available multivitamin and mineral tablets each day.

During the first and second periods in the MRU, they were given identical 3-d rotating diets that contained the recommended amounts of all known essential nutrients. Compliance was checked by counting pills and by stool collections twice during the free-living period. These suggested that compliance was about 85% to 90% during the free-living period. During the MRU period, the additional copper was added to the diet.

    研究共分3個階段, 第1及3階段各為期18天, 受試者活動範圍僅限於"西方人種營養研究中心"之"代謝研究室"(MRU), 第2階段則是為期129天的自由活動期.

    第1階段在MRU中每天餵食含 1.6mg 銅(硫酸銅形式)之飲食, 而129天的自由活動期間受試者於其日常飲食中額外補充攝取銅(每日7mg),之後返回MRU繼續餵食與第1階段相同的飲食並補充銅6.2mg, 總計每日銅攝取量為7.8mg, 約相當於一般人日常飲食外加每天服用2-3粒綜合維他命及礦物質錠之含量.

    在MRU的2個階段受試者被餵予相同的飲食且每3天循環1次, 飲食中含所有必需營養素每日建議攝取量, 並額外補充銅. 自由活動期間以計算所服用的含銅錠劑數量及2次收集糞便方式檢測受試者之依循性, 結果顯示額外補充攝取銅依循性約為85-90%.
