Cassava contains little zinc, iron, and β-carotene, yet it is the primary staple crop of over 250 million Africans. This study used a 24-hour dietary recall to test the hypothesis that among healthy children aged 2–5 years in Nigeria and Kenya, cassava’s contribution to the childrens’ daily diets...

The effect of different packages and storage conditions on the retention of pro-vitamin A carotenoids (pVAC) in ogi powder produced from yellow-seeded maize was investigated to study its storage stability on micronutrient retention. The ogi powder produced was packaged in a high-density polyethyl...

Background As part of the HarvestPlus provitamin A-biofortified cassava program in Nigeria we con- ducted a survey to determine the cassava intake and prevalence of vitamin A deficiency among children 6-59 months and women of childbearing age in the state of Akwa Ibom. Methods A cluster-randomize...

Vitamin A deficiency (VAD) is prevalent in most developing countries. Increasing provitamin A carotenoid content in staple crops such as yam, maize and cassava can minimize this deficiency. Yam (Dioscorea species) is a major staple food in many tropical and subtropical countries. Despite its wide...

Menkir, A.Pixley, K.Maziya-Dixon, B.B.Gedil, M.[Recent advances in breeding maize for enhanced pro-vitamin A content]Recent advances in breeding maize for enhanced pro-vitamin A content

Background: Whereas conventional white cassava roots are devoid of provitamin A, biofortified yellow varieties are naturally rich in b-carotene, the primary provitamin A carotenoid. Objective: We assessed the effect of consuming yellow cassava on serum retinol concentration in Kenyan schoolchild...
