Role of proper sampling in the estimation of the daily intake of some trace elements by the adult indian population

摘要

Trace elements are known to play an important role in human health. Whereas the essential trace elements are known to sustain life, the toxic ones affect human health adversely. Taken together, their intake and retention in the body have implications for human health. The study of the daily intake of these trace elements by the normal Indian population can provide important baseline data, against which changes and the possible health effects could be studied. The estimation of the daily dietary intake of the trace elements is generally carried out by the trace element analysis of either a: (1) duplicate diet, (2) institutional diet, or (3) market basket study. In order to assess the possible variations in the intake data obtained by these three different approaches, a preliminary study was made to obtain the estimate of the daily dietary intake by the adult Indian population employing the three approaches. The results obtained are reported.
