Biofortification of food crops with selenium is considered to be one of the most effective and economically beneficial way in the human selenium status optimization. At the same time as biologically activity of selenium is determined not only by a dose but also by chemical forms of the element it seems especially important to reveal peculiarities of their biosynthesis by different agricultural crops. The review presents the last data on the chemical forms of selenium in food products including food crops. Effect of agricultural crops biofortification with selenium on accumulation of special chemical forms of the element is discussed. Special attention is paid to representatives of Allium and Brassica species, capable to accumulate high concentrations of methylated derivatives of the element known to possess intensive anticarcinogenic acitivity. Selenium metabolism in hyperaccumulators and non-accumulators of selenium is discussed. Possible beneficial effects of selenium enriched cereals and vegetables on human health are presented. Success of Finland in improvement of human health via global utilization of fertilizers, fortified with selenium is indicated. The most important functional food products based on selenium fortified vegetables produced in different countries and developed in Russia are described.
用硒对粮食作物进行生物强化被认为是优化人体硒状况最有效且经济有益的方法之一。由于硒的生物活性不仅取决于剂量，还取决于该元素的化学形态，因此揭示不同农作物中硒生物合成的特点显得尤为重要。这篇综述介绍了包括粮食作物在内的食品中硒化学形态的最新数据。讨论了用硒对农作物进行生物强化对该元素特定化学形态积累的影响。特别关注了葱属和芸苔属植物的代表，它们能够积累高浓度的该元素甲基化衍生物，已知这些衍生物具有强烈的抗癌活性。讨论了硒超积累植物和非积累植物中的硒代谢。介绍了富硒谷物和蔬菜对人体健康可能产生的有益影响。指出了芬兰通过全球使用添加硒的肥料在改善人类健康方面取得的成功。描述了不同国家生产并在俄罗斯开发的基于富硒蔬菜的最重要功能性食品。
