چکیده

The estimated prevalence of vitamin A deficiency (VAD) was 29% among all low and middleincome countries and 48% for Sub-Saharan Africa in 2013 (1). This burden is predicted to contribute to 105,700 excess deaths globally, with 62,500 of those occurring in sub-Saharan Africa. Increasing vitamin A intake through biofortification of staple foods, such as cassava or maize, with provitamin A carotenoids has several potential advantages, including 1) expected low cost of the intervention after breeding and testing are complete, 2) the potential to reach rural populations that may not have consistent access to health service delivery platforms, and 3) because conversion of β-carotene to retinol is regulated, β-carotene does not contribute to excessive vitamin A. Yellow cassava varieties with high provitamin A content have been identified and selectively bred with African varieties, which are typically white, with no vitamin A.
