Define Trace elements for school children and adolescents?
Iodine requirements peak in adolescence. Consumption of iodized salt should be ensured. Adequacy of zinc for growth is well established. There are no specific age-wise requirements but adult zinc requirements are 15.5 mg /d and iodine 150 mcg/d (ICMR, 1990). These trace elements have great significance in this period of second growth spurt and further work is needed to delineate their requirements.
For FAO/WHO 2004 recommendations for vitamins and minerals for children and adolescents, we suggest you look up Units 7, 8, 9 and 10 under the respective vitamins and minerals.
