Iron fortification: country level experiences and lessons learned.
Iron fortification has been used to enhance iron intake in many developed countries for more than 50 years, but only in the last decade has this strategy been applied on a large scale to other parts of the world. Iron fortification of rice is being instituted in the Philippines. Initially, the rice will be produced in government-controlled rice mills and sold at low cost mainly to low income families. Efforts to improve the technology (using coating or extrusion techniques) are currently underway to reduce cost and minimize losses during storage and washing. Effectiveness and feasibility studies are required to test the new technologies and processing/distribution systems. In Venezuela in 1993, the government instituted a mandatory program of iron fortification to enrich precooked corn flour followed by the voluntary fortification of wheat flour. Surveys in school children subsequently showed a sharp drop in iron deficiency. Fortification of fish sauce in Vietnam has shown promising initial results in reducing anemia among anemic, nonpregnant female factory workers. Iron-fortified soy sauce has been shown to reduce anemia in initial studies in children in China, and a large-scale efficacy trial is now underway. These examples indicate that iron fortification of staple foods and condiments holds great promise for the prevention of iron deficiency.
