Iron bioavailability from unfortified (meal A) and FVRice-iron fortified (meal B) based meals was determined by simultaneous determination of 55 Fe and 59 Fe in blood in 20 healthy human subjects. FVRice-iron fortified was prepared by mixing 1 part of premix rice to 200 parts by weight of ordinary rice. The total iron content of the FVRice-iron fortified alone (uncooked) was 5.71 mg/100g; 2.84 mg/100g, when given as a mixed diet. The geometric mean iron absorption of 6.88 percent from Meal A was significantly higher than that obtained for Meal B of 5.41 percent. However, the amount of iron absorbed increased significantly from 0.30 to 0.40 mg (.01) when the total non-heme iron content was considered. Consumption of 120-150 g rice daily might satisfy about 65-81 percent of the iron requirements of 1-3 yr children, thus meeting more than the goal of 40-50 percent RDA [required dietary allowance] for this age group. The use of ferrous sulfate as fortification iron to rice seems to be effective, supplying an appropriate amount of absorbable iron
