Iron intakes and iron status (serum ferritin and iron balance) were determined in 16 women and 13 men consuming self-selected diets over a 1-yr period. Iron balance was determined during four 7-day balance periods corresponding to the four seasons of the year. The seasonal variation in iron intake and serum ferritin and the correlation among iron intake, iron balance, and serum ferritin was examined. No seasonal variation was found in iron intake or serum ferritin. No direct correlation could be found between iron status (ferritin levels and iron balance) and iron intake. However, the men who met or exceeded their recommended dietary allowance for iron intake had ferritin levels in a range indicative of adequate iron status. None of the women met their recommended dietary allowance and their ferritin levels indicated marginal iron stores.
对16名女性和13名男性进行了为期1年的研究，他们食用自行选择的饮食，测定了铁摄入量和铁状态（血清铁蛋白和铁平衡）。在与一年四个季节相对应的四个为期7天的平衡期内测定铁平衡。研究了铁摄入量和血清铁蛋白的季节性变化以及铁摄入量、铁平衡和血清铁蛋白之间的相关性。未发现铁摄入量或血清铁蛋白有季节性变化。在铁状态（铁蛋白水平和铁平衡）与铁摄入量之间未发现直接相关性。然而，铁摄入量达到或超过推荐膳食摄入量的男性，其铁蛋白水平处于表明铁状态充足的范围内。没有一名女性达到其推荐膳食摄入量，并且她们的铁蛋白水平表明铁储备处于边缘状态。
