摘要

背景/目的:尽管碘是甲状腺激素产生和控制许多新陈代谢过程所必需的元素,但由于缺乏有关食物中碘含量的信息,有关居民碘摄入量的报道很少。本研究估算了韩国人从褐藻(自然界中碘的主要来源)中摄入碘的情况:本研究利用韩国国民健康与营养调查(2016-2021 年)的膳食摄入量数据和褐藻中的碘含量进行估算。研究人员在全国范围内采集了褐海藻样本,并采用韩国人膳食中具有代表性的制备/烹饪方法进行制备,然后通过碱性消化和电感耦合等离子体质谱法进行碘分析:韩国人从海芥菜中摄入碘的平均值(± SE)为 96.01 ± 2.36 µg/天。虽然海带中的碘含量约为海芥菜的 7 倍,但从海带(汤汁除外)中摄入的碘平均值与海芥菜相似,为 115.58 ± 7.71 微克/天,而从海带汤汁中摄入的碘平均值为 347.57 ± 10.03 微克/天。从褐藻中摄入碘的总平均值为 559.16 ± 13.15 微克/天,远远超过韩国人的碘营养推荐摄入量。然而,摄入量的中位数为零,因为在调查日只有 37.6% 的人食用褐藻,这表明韩国人并非每天都食用褐藻:结论:韩国人通常从糙米海藻中摄入碘的分布会更紧密,导致超过可耐受摄入量上限的人口比例更低,平均摄入量也可能低于本研究的结果。根据通常的摄入量对韩国人的碘营养进行评估的进一步研究是有必要的。尽管如此,这项研究还是为为数不多的有关韩国人碘营养状况的报告增添了新的内容。

Iodine intake from brown seaweed and the related nutritional risk assessment in Koreans.

Background/objectives: Although iodine is essential for thyroid hormone production and controls many metabolic processes, there are few reports on the iodine intake of the population because of the scarcity of information on the iodine content in food. This study estimated the iodine intake of Koreans from brown seaweed, the major source of iodine in nature.

Subjects/methods: The dietary intake data from the recent Korea National Health and Nutrition Examination Survey (2016-2021) and the iodine content in brown seaweed were used for the estimation. Nationwide brown seaweed samples were collected and prepared using the representative preparation/cooking methods in the Koreans' diet before iodine analysis by alkaline digestion followed by inductively coupled plasma mass spectrometry.

Results: The mean (± SE) iodine intake from sea mustard was 96.01 ± 2.36 µg/day in the Korean population. Although the iodine content in kelp was approximately seven times higher than that in sea mustard, the mean iodine intake from kelp (except broth) was similar to that of sea mustard, 115.58 ± 7.71 µg/day, whereas that from kelp broth was 347.57 ± 10.03 µg/day. The overall mean iodine intake from brown seaweed was 559.16 ± 13.15 µg/day, well over the Recommended Nutrient Intake of iodine for Koreans. Nevertheless, the median intake was zero because only 37.6% of the population consumed brown seaweed on the survey date, suggesting that Koreans do not consume brown seaweed daily.

Conclusion: The distribution of the usual intake of iodine from brown seaweed in Koreans would be much tighter, resulting in a lower proportion of people exceeding the tolerable upper intake levels and possibly a lower mean intake than this study presented. Further study evaluating the iodine nutriture of Koreans based on the usual intake is warranted. Nevertheless, this study adds to the few reports on the iodine nutriture of Koreans.

The journal had been published quarterly at the initial stage and has been published bimonthly since 2010. NRP aims to stimulate research and practice across diverse areas of human nutrition. The Journal publishes peer-reviewed original manuscripts on nutrition biochemistry and metabolism, community nutrition, nutrition and disease management, nutritional epidemiology, nutrition education, foodservice management in the following categories: Original Research Articles, Notes, Communications, and Reviews. Reviews will be received by the invitation of the editors only. Statements made and opinions expressed in the manuscripts published in this Journal represent the views of authors and do not necessarily reflect the opinion of the Societies.
