How should dietary guidance be given for mineral elements with beneficial actions or suspected of being essential ?
Workshop on New Approaches, Endpoints and Paradigms for RDAs of Mineral Elements. Grand Forks, ND USA, 1995/09/10.
The term ultratrace elements, often used to indicate elements with an established, estimated or suspected requirement generally indicated by mug/d, could be applied to at least 20 elements.
The quality of experimental evidence for nutritional essentiality varies widely for the ultratrace elements.
Thus, although differing dietary guidance is appropriate for these elements, most need increased attention in future editions of the Recommended Dietary Allowances (RDAs) for the following reasons : (1) Increased interest in these elements by the public has been stimulated by the mass media ; thus, responsible information about the usefulness of the ultratrace elements for health and well being is needed. (2) Risk assessments and toxicological standards are influenced by the RDAs.
Authorative advice is required to prevent standards that obstruct the achievement of beneficial intakes of ultratrace elements. (3) An emerging new paradigm is that the determination of nutritional requirements should include consideration of the total health effects of nutrients, not just their roles in preventing deficiency pathology ; some of the ultratrace elements have identified health benefits.
Six ultratrace elements, iodine, selenium, manganese, molybdenum, chromium and boron (and cobalt as vitamin B12), merit specific RDAs. (...)
