Taken with a grain of salt? : micronutrient fortification in South Asia

This article reviews the research on fortification of food in the context of South Asia, with an emphasis on avenues for future research in economics and policy. We argue that while the efficacy of fortified foods in controlled settings is well established, more research is needed to evaluate the take-up and effectiveness of fortified foods distributed through standard channels. In addition, we argue that more research is needed to understand the determinants of long-term demand for fortified foods.
