Widely consumed is daal (lentils) are an ideal vehicle for iron (Fe) fortification. It was critical to determine an acceptable portion size of daal in meals to carry out a subsequent study to assess the efficacy of the fortified lentils in improving iron status of a population. This community-based non-randomized crossover feeding trial was designed to determine the portion size that the adolescent girls in rural Bangladesh could feasibly consume. Results show that 37.5 g of raw lentil in a thick cooking preparation using a local recipe was most acceptable. Results of this research are important for future iron-fortified lentils programing.
