In regions with low selenium soil concentrations, selenium can be considered a critical nutrient for vegetarians and vegans. While the number of vegetarians and vegans is increasing in many countries, a large research gap remains in this field. For example, to date, no study seems to have assessed selenium intake in vegetarian and vegan children. Therefore, the selenium intake of 1- to 3-year-old vegetarian, vegan, and omnivorous children who participated in the cross-sectional VeChi Diet study was determined. Selenium intake was assessed based on 3-day food diaries (not including supplements) and food selenium concentrations provided by the European Food Safety Authority (EFSA). Between-group differences were assessed with analysis of covariance (ANCOVA). The median daily selenium intake was 17 µg, 19 µg, and 22 µg in vegetarian, vegan, and omnivorous children, respectively. However, only the difference between the vegan and omnivorous children was statistically significant. On average, all three groups met the harmonized average requirement (H-AR) for selenium of 17 µg/day. Nevertheless, the hypothesis that vegetarian and vegan children generally consume less selenium than omnivorous children could be confirmed, and 39% of vegetarians, 36% of vegans, and 16% of omnivores fell below the adequate intake for selenium (provided by EFSA) of 15 µg/day.
在土壤硒浓度低的地区，硒可以被认为是素食者和纯素食者的关键营养物质。虽然许多国家的素食者和纯素食者人数正在增加，但该领域仍存在大量研究空白。例如，迄今为止，似乎没有研究评估过素食和纯素食儿童的硒摄入量。因此，本研究通过横断面研究 VeChi Diet 来确定了 1 至 3 岁的素食、纯素和杂食儿童的硒摄入量。通过 3 天的饮食日记（不包括补充剂）和欧洲食品安全局（EFSA）提供的食物硒浓度来评估硒的摄入量。采用协方差分析（ANCOVA）评估组间差异。素食、纯素和杂食儿童的平均每日硒摄入量分别为 17µg、19µg 和 22µg。然而，只有纯素和杂食儿童之间的差异具有统计学意义。平均而言，所有三组均符合 17µg/天的硒平均需要量（H-AR）。尽管如此，素食和纯素食儿童的一般硒摄入量普遍低于杂食儿童的假设得到了证实，39%的素食者、36%的纯素食者和 16%的杂食者的硒摄入量低于欧洲食品安全局（EFSA）提供的 15µg/天的适宜摄入量。
