Phytate in the Filipino diet and its correlation with iron status an exploratory study 2003 This study determined the phytate intake of Filipino women and explored its correlation with indices of human iron status. Using the World Foods Dietary Assessment System, mean phytate intake of 130 women participants in the feeding trial for iron biofortified rice was computed at 1072mg/day. More than half of this amount was from rice inasmuch as rice constitutes the bulk of the diet. Nuts, dried beans and seeds contributed the highest phytate per unit food intake with cashew, peanuts, and pigeon peas having the highest phytate content. Their consumption ranged from 15.0g to 34.4g, providing an estimated 264.0mg to 520.92mg phytate. Neither total phytate intake nor phytate intake from different food groups was correlated with any of the human iron status indices as hemoglobin, serum ferritin, and total body iron. This suggests that the level of phytate intake of these Filipino women may be low to cause an inhibitory effect. It may also be possible that other dietary constituents negate the inhibitory effect of phytate on iron absorption since the intake of known iron enhancers Vitamins C and A strongly correlate with all three iron indices. Further bioavailability and field studies are thus recommended to verify such trends. Analysis of phytate content of Filipino foods should be a priority. Roferos, L. T. Bandonill, E. H. Juliano, B.
