Dietary Selenium-Enriched Aquatic Products for Human Health

Aquatic products are among the best sources of high-quality protein for humans. Selenium is also an essential trace element for animal growth and development. In animals, selenium primarily exists as selenoproteins, which perform vital physiological functions such as providing antioxidant protection, regulating the immune system, and facilitating growth and reproduction. Twenty-four of the selenoproteins identified in humans have also been found in aquatic animals. As living standards rise and health awareness grows, consumers are increasingly favoring selenium-enriched aquatic products. This article systematically reviews the advantages of these products, selenium levels in different farmed animals, and dietary recommendations. It also explores the functions of selenoproteins in these products. The article emphasizes the importance of selenium for human health and discusses its relationship with health. It also explores the application prospects of selenium-enriched aquatic products. The goal is to provide a scientific basis for utilizing these products and to guide consumers in supplementing their selenium intake.
