The report finds that the vast majority of industrially produced breads and tortillas in Mexico fail to meet the minimum iron and zinc levels mandated by the NOM-247-SSA1-2008 regulation. Testing revealed that only 14% of bread products and 1.5% of tortilla products were adequately fortified. Furthermore, 84% of both product types were suspected of using elemental iron, a less-bioavailable source not recommended by the regulation or WHO guidelines. The report highlights a regulatory loophole where the law mandates fortification for flour producers but does not explicitly require food processors to procure and use that fortified flour. Major companies like Grupo Bimbo and Gruma were specifically analyzed, with Gruma's tested products failing to meet any minimum requirements for iron or zinc.
