Dietary Requirements of Trace Elements

A Brief Overview of Population and Individual Requirements as Specified in Some Recent International and National Recommendations
  • R. M. Parr


During the past decade, new estimates of desirable levels of dietary intake of essential trace elements have been developed by several different national and international groups of experts. Their work has been stimulated partly by scientific advances in our knowledge of the role of trace elements in human nutrition and health, and partly also by the need for more accurate and informative food labelling. Although these experts have all had access to more or less the same, or very similar, sets of scientific data on which to base their conclusions, their recommendations show large numerical differences arising from different philosophical approaches and assumptions. Within a short publication such as this it is not feasible to present a comprehensive review of this subject. Instead, this report places emphasis on the recently developed recommendations of WHO, FAO and IAEA (1) and draws some comparisons with similar recommendations from the USA (2), ILSI Europe (3), and the UK (4).
