The aim of this research was to estimate the effect of a vegan diet on the Recommended Dietary Allowance (RDA) coverage for iodine in people from Poland. It was hypothesized that the problem of iodine deficiency is a concern, especially among vegans. The survey study was conducted in the years 2021-2022 on 2200 people aged 18-80 with omnivore and vegan diets. The exclusion criteria in the study were pregnancy and lactation. The study found that the coverage of RDA for iodine among people with a vegan diet was lower than among people with an omnivore diet ( < 0.05); 90% of the participants with a vegan diet had an iodine intake below 150 µg/day. Plant-based dairy and meat analogs were consumed by vegans frequently and in large portions, but none were fortified with iodine. It was found that iodized salt was each group's primary source of iodine. However, it was observed that the iodine supply from this source was limited among vegans, especially in female subjects, who consumed less salt and smaller portions of meals. That is why consideration should be given to the iodine fortification of plant-based foods commonly consumed by vegans.
本研究旨在评估素食对波兰人推荐膳食允许量（RDA）碘覆盖的影响。假设碘缺乏问题是一个关注点，尤其是对于素食者而言。这项调查研究于 2021 年至 2022 年在 2200 名年龄在 18 至 80 岁的杂食者和素食者中进行。研究中的排除标准为怀孕和哺乳期。研究发现，素食者的 RDA 碘覆盖率低于杂食者（<0.05）；90%的素食者碘摄入量低于 150μg/天。素食者经常大量食用植物性奶制品和肉类替代品，但它们都没有强化碘。研究发现，碘化盐是各组碘的主要来源。然而，研究发现，素食者的碘供应来源有限，尤其是女性，她们摄入的盐和餐量较少。因此，应该考虑对素食者经常食用的植物性食物进行碘强化。
