Modelling potential β-carotene intake and cyanide exposure from consumption of biofortified cassava
Vitamin A (VA) deficiency causes disability and mortality. Cassava can be crossbred to improve its β-carotene (BC) content; typical white cassava contains negligible amounts of BC. However, cassava contains cyanide and its continued consumption may lead to chronic disability. Our objective was to estimate the risk-benefit of consuming BC-enhanced cassava to increase VA intake. A total of ten Am...
متن کاملGene expression of beta carotene genes in transgenic biofortified cassava
Cassava is an important food for millions of people around the world. However, cassava is deficient in protein, iron, zinc, pro-vitamin A and vitamin E. Cassava biofortified with pro-vitamin A can help reduce Vitamin A Deficiency among the undernourished communities that rely upon it for sustenance. BioCassava Plus project has developed transgenic cassava that expresses beta carotene in roots u...
متن کاملBiofortified cassava increases β-carotene and vitamin A concentrations in the TAG-rich plasma layer of American women.
Biofortification of cassava with the provitamin A carotenoid β-carotene is a potential mechanism for alleviating vitamin A deficiency. Cassava is a staple food in the African diet, but data regarding the human bioavailability of β-carotene from this food are scarce. The objective of the present study was to evaluate provitamin A-enhanced cassava as a source of β-carotene and vitamin A for healt...

متن کاملBiofortified yellow cassava and vitamin A status of Kenyan children: a randomized controlled trial.
BACKGROUND Whereas conventional white cassava roots are devoid of provitamin A, biofortified yellow varieties are naturally rich in β-carotene, the primary provitamin A carotenoid. OBJECTIVE We assessed the effect of consuming yellow cassava on serum retinol concentration in Kenyan schoolchildren with marginal vitamin A status. DESIGN We randomly allocated 342 children aged 5-13 y to receiv...
