Selenium is an essential trace element in human nutrition, which is an integral part of the peroxide destroying enzyme, glutathione peroxidase (1). It also takes part in the constitution of other selenoproteins (2) and seems to play other biological functions, such as an important role in the peripheric deiodination of thyroid hormones (3). Normal selenium status varies widely from one part of the world to another. This situation, which is the consequence of differences in selenium intake, depends on the selenium content in soils and hence in food, as well as its bioavailability (4). Moreover, different physiological conditions and also the occurrence of pathological situations are liable to influence the status of the element in human beings.
