Guava with an institutional supplementary meal improves iron status of preschoolers: a cluster-randomized controlled trial.

The Integrated Child Development Services of India provides Supplementary Nutrition Program (SNP) to preschoolers. Using this platform, the current study examined the impact of diversifying a cereal/pulse-based SNP-meal with guava on iron status and cognitive development among 24-48 months old children. A three-arm, nonblinded, cluster-randomized controlled trial (CTRI/2014/09/004983) included 399 beneficiaries from 28 preschools in 16 villages in Telangana state, India.
