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（Se）是生物体的重要微量元素，因为它参与了几种生理和代谢过程。人类摄入的硒通常很低，很少过量，其生物利用度还取决于其化学形式，有机硒是摄入后的最有效形式。人类硒的主要膳食来源是植物，因为许多物种能够代谢和积累可食用部分中的有机硒（叶、花、果实、种子和芽），或者在加工后（油、酒等）食用。最近，无数研究调查了植物的硒生物强化作用，以生产富含硒的食物，并诱导次生代谢物的产生，当这些次生代谢物被纳入饮食时，可能有益于人类健康。此外，用富含硒的饲料喂养动物可以提供富含硒的肉类。这项工作综述了植物和动物来源的富含硒的食物的营养特性的最新文献。
