As part of an international nutrition project sponsored by the International Atomic Energy Agency (see footnote), Vienna, Austria, a number of bench-mark mixed total diet composites from the United States were collected and analyzed for minor and trace elements. In this segment of the project, the daily dietary intakes of the minor elements Ca, Cl, K, Mg, N and P and the trace elements Al, As, Au, Br, Cd, Co, Cr, Cs, Cu, Fe, Hg, I, Mn, Mo, Ni, Pb, Rb, Sb, Sc, Se, Sn, Sr, V, Zn and W were determined in mixed total diet composites of foods collected in the FDA Total Diet Study (FDA-TDS). These diets are representative of foods consumed by 25-30-year-old males (representing the mixed population groups in the United States), the highest of eight intake groups in the TDS scheme. In order to link the US mixed diet composite results from this study group to the more comprehensive information generated by the FDA-TDS, the results are compared with the same age-sex group published by the FDA-TDS scheme. The FDA-TDS scheme is based on individual analysis of the 201 food items, with resultant calculation of the daily intake representative of various age-sex groups. The comparison shows excellent agreement for 21 elements which have been investigated by both approaches. Additional elements are reported in the US mixed diet composites from the present study which demonstrate a valuable supplement to the data obtained by FDA-TDS scheme. Further the mixed total diet composite approach has also proven useful for the assessment of dietary intake of proximates (protein, fat, carbohydrates), fiber and phytate. In addition, vitamins thiamin, riboflavin, niacin, B6, B12, pantothenic acid, folic acid and biotin were also assayed in these composites.
作为由国际原子能机构（见脚注）赞助的一项国际营养项目的一部分，从美国收集了一些具有代表性的混合总膳食样本，并对其进行了微量元素和痕量元素分析。在该项目的这一阶段，测定了美国食品药品监督管理局总膳食研究（FDA-TDS）中收集的混合总膳食样本中微量元素钙、氯、钾、镁、氮和磷以及痕量元素铝、砷、金、溴、镉、钴、铬、铯、铜、铁、汞、碘、锰、钼、镍、铅、铷、锑、钪、硒、锡、锶、钒、锌和钨的每日膳食摄入量。这些膳食代表了25至30岁男性（代表美国的混合人群组）所消费的食物，这是TDS计划中八个摄入量组中摄入量最高的一组。为了将本研究组的美国混合膳食样本结果与FDA-TDS生成的更全面信息联系起来，将这些结果与FDA-TDS计划公布的同一年龄性别组结果进行了比较。FDA-TDS计划基于对201种食品的单独分析，并据此计算出代表不同年龄性别组的每日摄入量。比较结果表明，两种方法所研究的21种元素具有极佳的一致性。本研究在美国混合膳食样本中报告了其他元素，这些元素对FDA-TDS计划获得的数据是有价值的补充。此外，混合总膳食样本方法也已证明对评估近似营养素（蛋白质、脂肪、碳水化合物）、纤维和植酸盐的膳食摄入量很有用。此外，还对这些样本中的硫胺素、核黄素、烟酸、维生素B6、维生素B12、泛酸、叶酸和生物素进行了测定。
