Background Although the prevalence of Selenium (Se) deficiency is unknown, there is an anxiety that most Europeans may be deficient in this micronutrient because data show that recommended daily intakes are not achieved. Some countries have implemented an agricultural fertilization program to raise cereal selenium concentrations, thereby boosting dietary intakes. However, the relationships between dietary reference values (DRVs), Se adequacy and optimum selenoprotein activity are unknown, while the functional sequelae of inadequate Se supply remain uncharacterized. Scope and approach This commentary examines the benefits and disbenefits associated with Se supplementation. It highlights the inadequacy of currently used surrogate markers of Se status and an absence of clinical data to support stated benefits. The aim is therefore to stimulate debate about whether we really need more than the variable amounts we already consume. [ABSTRACT FROM AUTHOR] |
