Daily dietary intakes of 28 trace elements were estimated from 24-food duplicate records of 456 adult women. The estimates made it possible to classify the elements into three groups of high (i.e., >1 mg/day as a median ; 7 elements of Al, Cu, Mg etc.), medium (2-985 ug/day ; 13 elements of As, B,Ba, Be etc.) and low intake (<1 ug/day ; 5 elements of Cd, Co, Li etc.). Published values for the element intake were available for 15 elements among the 28. Comparison showed that the food composition-based estimates tended to agree with the published values only when the estimated intakes were above 1 ug/day, but the discrepancies were evident for four elements of low intake (i.e., <1 ug/day). In a subsequent study, 24-hour total food duplicates were collected from 231 adult women in 9 prefectures in Japan, and dietary intakes of 5 minerals [sodium (Na), potassium (K), phosphorus (P), calcium (Ca) and iron (Fe) ] were estimated from the weights of food items in each duplicate sample by use of food composition tables. Food components in each duplicate sample was homogenized and wet-ashed for element determination by inductively-coupled plasma spectrometry (ICP). The comparison of the two sets of values, the estimates and ICP-measured values, showed that the estimates were significantly larger than the measured values in cases of Na (the ratio of the estimated over the measured ; 118%), K (115%), Ca (109%) and Fe (130%), whereas the two values did not differ from each other in case of P (the ratio ; 93%). Thus, food composition-based estimation carries the risk of over-estimation in case of Na, K,Ca and Fe, but not so in case of P.

根据 456 名成年女性的 24 种食物重复记录估算了 28 种微量元素的每日饮食摄入量。通过估算，可以将元素分为三组：高摄入量（即中位数 >1 毫克/天；Al、Cu、Mg 等 7 种元素）、中摄入量（2-985 ug/天；As、B、Ba、Be 等 13 种元素）和低摄入量（<1 ug/天；Cd、Co、Li 等 5 种元素）。 28 种元素中，有 15 种元素的摄入量已公布。比较表明，只有当估计摄入量高于 1 微克/天时，基于食物成分的估计值才倾向于与公布的值一致，但对于四种低摄入量（即 <1 微克/天）的元素，差异很明显。在随后的研究中，从日本 9 个县的 231 名成年女性中收集了 24 小时总食物重复数据，并使用食物成分表根据每个重复样本中的食物重量估算了 5 种矿物质 [钠 (Na)、钾 (K)、磷 (P)、钙 (Ca) 和铁 (Fe)] 的膳食摄入量。将每个重复样品中的食品成分均质化并湿灰化，以便通过电感耦合等离子体光谱法 (ICP) 进行元素测定。两组值（估计值和 ICP 测量值）的比较表明，在 Na（估计值与测量值的比率；118%）、K（115%）、Ca（109%）和 Fe（130%）情况下，估计值显着大于测量值，而在 P 情况下（比率；93%），两个值没有差异。因此，基于食物成分的估算对于 Na、K、Ca 和 Fe 存在高估风险，但对于 P 则不然。
