title: [Trace elements, human nutrition and health].
abstract: The importance of trace elements as essential dietary constituents is not sufficiently appreciated by the medical profession, although in recent years a significant increase of new finding on their essential character in nutrition occurred as well as of data on changes in the composition of the diet which can cause their deficiency and in some instances a toxic excess. The diagnosis of deficiency or excess of these substances in the organism is very complicated. because their blood level frequently does not provide sufficient information on their reserves in the organism and new laboratory methods suited for this purpose must be developed and tested. The interpretation of the assembled results is very pretentious and it will be therefore necessary to expand teaching of nutrition, where the problem of trace elements no doubt belongs, into undergraduate and postgraduate medical curricula to prevent health damage due to inadequate intake of trace elements as well as uncontrolled intake of freely available preparations sold as supplements.
