ADVANCES IN RESEARCH ON BIOLOGICAL CYCLE OF SE AND ACTIVE SE-CONTAINING SUBSTANCES

As an essential trace element, selenium (Se) is of fundamental importance to human health. There is evidence that less - overt Se deficiency can have adverse consequences for many diseases susceptibility. Se enters the food chain through plants, which take it up from the soil. Supplementation in a large scale with Se - containing products significantly decreased in diseases (eg, cardiovascular disease, cancer, viral infection etc.) morbidity and mortality of individuals in the regions notable for their low soil content of Se. Recognition of the importance of biological cycle and bio - organized pathway of Se helps us in promoting the exploitation of active se - containing products. Advances in the studies on biological cycle of Se and active se - containing products are reviewed.
