About 230,000 children unnecessarily developed FAP SBA globally in 2017. There is an urgent need for all countries to implement mandatory folic acid fortification, a proven, safe public health intervention that saves money and prevents infant mortality and disability. Prevention of FAP SBA can play an important role in helping countries to achieve their Sustainable Development Goals for health.
We estimate an increasing prevention of FAPSBA in the world through folic acid fortification, yet the pace is slow. Our new model estimates that only 25% prevention and reminds us that there remains a lot of work to do in countries that do not implement mandatory fortification, which is key to achieving global and total prevention. If we are to prevent all FAPSBA, there is an urgent need to build the global political will to find sufficient resources to aid in this effort.
Factors to guide a decision to fortify flour with vitamin A include the extent of deficiency, availability of other food vehicle options, the centrality of milling, market reach and population intake distributions of the flour products, the dietary vitamin A intake required, and associated costs. Large gaps persist in knowledge of these factors, which are needed to enable evidence-based fortification in most countries, leaving most decisions to fortify guided by assumptions. Where flour can and should be fortified, guidelines are given for providing nearly 25% of the Recommended Dietary Allowance for vitamin A to vulnerable groups consuming varying ranges of flour products. The costs will vary according to the level of fortification.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
