This study explored the impact of providing salt fortified with iron and iodine to Indian children in second grade on anemia and cognition. Baseline and endline data were collected from children in the intervention and control groups, and fortified salt was delivered through the school feeding program to the intervention group over three months. Researchers found that children who received fortified salt were less likely to suffer from anemia and had higher school attendance. Reading and math outcomes were statistically insignificant; however, both were positively influenced by higher school attendance.
