Articles focus on iron fortification practices and the implications of adding iron to salt, and whether double fortification salt (DFS) with iron and iodine reduce anemia, iron deficiency anemia, iron and iodine deficiencies, and functional outcomes. Other investigations evaluate large-scale DFS programs, the potential of iodine and iron DFS to increase population iron status compared with iron-fortified staple foods, and challenges and evidence for policymakers considering iodized salt as a vehicle for iron fortification.
