Fighting child malnutrition in sub-Saharan Africa
The nutritional value of staple foods in Africa is being boosted to raise consumption of essential micronutrients. Kenya has made iron fortification mandatory in commercially produced flour, while Nigerias farmers are being encouraged to grow high-vitamin-A cassava strains. Both moves result from the EU-funded INSTAPA project, which continues to inform efforts to step up public nutrition through improving foods.
Evidence from the project, which ended in November 2013, shows that fortifying staple foods with iron improves childrens cognitive development. This helped convince Kenyas Bureau of Standards to update its regulations on wheat and maize flour, says INSTAPA coordinator Inge D Brouwer of the Netherlands Wageningen University.
She says that the case for mass fortification was further strengthened by a trial in the project which showed that fortifying food with iron has no strong impact on malaria risk for expectant mothers taking antenatal iron supplements (the excess iron in the blood is thought to attract malaria-carrying parasites), while it increases new-born birthweights .
In Nigeria, vitamin-A-rich forms of cassava studied during the project are being promoted to farmers by national and international organisations. Unlike white cassava an African staple poor in nutrients selectively-bred yellow cassava strains contain vitamin A in a form that people absorb well, the project found.
Delivery models for the yellow cassava are designed, through the HarvestPlus programme, to avoid harming local markets, says Brouwer, and the strains are not subject to intellectual property restrictions. A new project in Nigeria CASSAVITA II will continue to test how well yellow cassava improves peoples vitamin A levels.
INSTAPA researchers have also been invited to take part in the US National Institute of Healths Iron Week summit in May 2015 to contribute to discussions about improving iron nutrition worldwide. Adds Brouwer: The strong evidence we have built up on improving staple food can convince policy-makers to invest in this work.
