Abstract

Phytate and trace element concentrations of the total daily diet of upper social groups in Taiwan were determined by P-31 FT NMR spectroscopy and by instrumental neutron activation analysis, respectively. Results of 15 samples are 2.21 +/- 0.71 g of phytate/kg of dry diet with the range 1.07-3.76 g/kg. The molar ratios of phytate to Zn and Ca were calculated, and bioavailabilities of these elements are discussed.
