Iodine food composition data of Norwegian foods have been sparse and knowledge about different dietary iodine sources limited. We compiled a comprehensive iodine food composition database and estimated dietary iodine intake among adults in the latest Norwegian national dietary survey (Norkost 3). The iodine content of food and beverages were compiled using international guidelines and standards. Iodine content of 3259 food items were compiled, including analytical values, values from other food composition databases, estimated values, and values that were based on recipes. Estimated iodine intake in the Norkost 3 population ranged from 15 to 1462 µg/day. Men had significantly higher intake of iodine than women ( < 0.001). The proportion of men and women with estimated iodine intake below average requirement was 19% and 33%, respectively. In young women, 46% had estimated iodine intakes below average requirement and a high probability of inadequate iodine intake. Several dietary sources contributed to iodine intake and differences in the consumption pattern may put subgroups at risk of insufficient iodine intake. In the coming years, the determination of iodine in foods and national dietary surveys should be regularly performed to monitor the iodine intake in the Norwegian population.
挪威的食物碘成分数据一直比较匮乏，人们对不同的饮食碘来源的了解也有限。我们编制了一个综合的碘食物成分数据库，并根据最新的挪威全国饮食调查（Norkost 3）估计了成年人的饮食碘摄入量。食物和饮料的碘含量是根据国际指南和标准编制的。我们共编制了 3259 种食物的碘含量，包括分析值、其他食物成分数据库的值、估计值和基于配方的值。在 Norkost 3 人群中，碘的摄入量范围为 15 至 1462 微克/天。男性的碘摄入量明显高于女性（<0.001）。估计碘摄入量低于平均需要量的男性和女性比例分别为 19%和 33%。在年轻女性中，46%的人估计碘摄入量低于平均需要量，碘摄入不足的可能性很高。有几个饮食来源会影响碘的摄入，不同的消费模式可能会使某些亚群面临碘摄入不足的风险。在未来几年，应定期进行食物中的碘含量测定和全国饮食调查，以监测挪威人口的碘摄入量。
