RATIONALE AND OBJECTIVES: Young children in Bangladesh are at risk of zinc deficiency due to a rice-based diet with few animal-source foods. Breeding rice for higher zinc content is a sustainable approach to increase zinc intakes. We
aimed to quantify usual rice and zinc intakes in young children and to estimate the potential impact of zinc biofortified rice on zinc intakes.
METHODS: We measured dietary intake in a representative sample of 480 children ages 24-47 mo in rural communities from two regions. Food intakes were estimated by weighed records in homes on two non-consecutive days. Absorbable zinc intakes were calculated based on the phytate:zinc ratio of the diets.
RESULTS: Preliminary data from 133 children from one community suggest a high risk of zinc deficiency based on serum zinc concentrations ,65ug/dL (48%) and inadequate intakes of absorbable zinc (24%). Rice provided ~60% of total dietary zinc. If rice zinc content were increased by 50% or 100%, the probability of inadequate zinc intakes would decrease to 5% or 0, respectively.
CONCLUSION: Zinc biofortification of rice has potential to significantly improve the zinc adequacy of diets of children in Bangladesh.
