The overall protection of cells from oxida tive damage dueto reactive oxygen species is mediated by enzymatic and non-enzymatic systems. Selenium, copper and zinc are essential trace elements with major roles, since they are related to Se-dependent glutathione peroxidase enymes and to Cu, Zn-containing superoxide dismutase. Epidemiological studies have been.carried out in recent years to investigate the association between some blood parameters implicated in the antioxidant function and health conditions. The influence of various factors like age, gender, diet, medical treatment and lifestyle has been considered, especially in residents of particular geographic areas. The aim of this work is to present data on serum selenium, copper and zinc concentrations in five populations with different socioeconomic and dietary habits living on the island of S. Miguel (Azores Archipelago, Portugal). (Introduction)
