A dietary study among 110 teenage girls and 87 pregnant women revealed that their mean iron intake was lower than the Recommended Dietary Allowances. The explanation is assumed to be a relatively low energy intake. Considering the composition of Scandinavian food, in which about 40% of the energy calories are derived from animal products, it is suggested that about 90% of all pregnant women can cover their iron requirement without further supplements.
一项针对110名少女和87名孕妇的饮食研究表明，她们的平均铁摄入量低于膳食推荐摄入量。据推测，原因是能量摄入量相对较低。考虑到斯堪的纳维亚食物的构成，其中约40%的能量卡路里来自动物产品，建议约90%的孕妇无需额外补充就能满足其铁需求。
