Selenium (Se) is an important micronutrient for living organisms, since it is involved in several physiological and metabolic processes. Se intake in humans is often low and very seldom excessive, and its bioavailability depends also on its chemical form, with organic Se as the most available after ingestion. The main dietary source of Se for humans is represented by plants, since many species are able to metabolize and accumulate organic Se in edible parts to be consumed directly (leaves, flowers, fruits, seeds, and sprouts) or after processing (oil, wine, etc.). Countless studies have recently investigated the Se biofortification of plants to produce Se-enriched foods and elicit the production of secondary metabolites, which may benefit human health when incorporated into the diet. Moreover, feeding animals Se-rich diets may provide Se-enriched meat. This work reviews the most recent literature on the nutraceutical profile of Se-enriched foods from plant and animal sources.

硒生物强化以改善食品的营养特征的最新知识：综述

硒（Se）对生物体来说是重要的微量营养素，因为它参与了几种生理和代谢过程。人体中的硒摄入量通常很低，很少很少过量，其生物利​​用度还取决于其化学形式，有机硒摄入后摄入量最多。人体主要硒的饮食来源是植物，因为许多物种能够在可食用部分直接代谢（叶，花，水果，种子和芽）或加工后（食用油，酒）食用和代谢有机硒。等）。最近进行了无数研究，研究了植物对硒的生物强化作用，以生产富含硒的食物并引发次级代谢产物的产生，将其纳入饮食中可能有益于人类健康。此外，喂养动物富含硒的饮食可以提供富含硒的肉。这项工作回顾了有关来自动植物的富硒食品的营养成分的最新文献。
