Biofortified cassava with provitamin A to improve vitamin A status (CASSAVITA II)
Nigeria is the largest producer of cassava worldwide and in some areas adults consume 950 g of cassava (raw fresh weight) per day on average. In comparison to East Africa, preparation methods of cassava based foods are different, which might affect the content and bioavailability of its pro-vitamin A.
Therefore, we conducted a second randomized controlled trial (following CASSAVITA I, conducted in Kenya previously) to study the efficacy of yellow cassava, this time among preschool children in Nigeria. Preschool children are more vulnerable to vitamin A deficiency than older children and therefore form an important target group for this strategy.
