“…As expected, weekly vitamin A intake was higher in the orange maize group (P < 0.05). Intakes of food and all nutrients, except vitamin A, increased by week (P < 0.05), supporting previous findings by Nuss et al, 24 which reported increasing intakes of menu items by week and similar intakes of all menu items after week 2 of the study.…”

Vitamin A supplementation improves status, which may protect against malarial infection. Provitamin A carotenoid biofortified staple crops may provide a more sustainable approach to alleviate vitamin A deficiency than supplementation, but the impact of febrile illness on food intake must be considered in malaria endemic regions. Morbidity data and food logs from a three-month efficacy trial on provitamin A biofortified (orange) maize in preschool Zambian children (n = 181, age 3-5 years) were systematically analyzed over time to determine the impact of malaria on food intake. Nutrients examined included macronutrients, iron, zinc, and vitamin A. Comparisons based on individual intakes in healthy and malarial states over three-day intervals were made including children from both the orange and white maize groups (n = 100). Malaria prevalence did not differ overall or between treatment groups over time (all P > 0.05). Lower nutrient intakes were observed for all variables during malaria outbreaks (food 289 ± 412 g; energy 248 ± 346 kcal; carbohydrate 42 ± 62 g; protein 8 ± 12 g; fat 5 ± 7 g; iron 1 ± 2 mg; zinc 1 ± 1 mg; vitamin A 58 ± 100 retinol activity equivalents; all P < 0.05). No differences were observed between nutrient decreases in orange and white maize groups (P > 0.05). Considering the impact of malaria on food and nutrient intakes and increased vitamin A utilization and excretion due to the acute phase response, biofortification targets for provitamin A carotenoids may need to be elevated in malaria endemic regions.

“…Maize, sweet potatoes, and cassava are being biofortified to contain higher concentrations of provitamin A carotenoids. Maize is a dietary staple for over 200 million people worldwide, providing approximately 20% of the world's calories . Approximately 70 million people obtain at least 500 calories a day from cassava .…”

International research efforts, including those funded by HarvestPlus, a Challenge Program of the Consultative Group on International Agricultural Research (CGIAR), are focusing on conventional plant breeding to biofortify staple crops such as maize, rice, cassava, beans, wheat, sweet potatoes, and pearl millet to increase the concentrations of micronutrients that are commonly deficient in specific population groups of developing countries. The bioavailability of micronutrients in unfortified staple crops in developing regions is typically low, which raises questions about the efficacy of these crops to improve population micronutrient status. This review of recent studies of biofortified crops aims to assess the micronutrient bioavailability of biofortified staple crops in order to derive lessons that may help direct plant breeding and to infer the potential efficacy of food-based nutrition interventions. Although reducing the amounts of antinutrients and the conduction of food processing generally increases the bioavailability of micronutrients, antinutrients still possess important benefits, and food processing results in micronutrient loss. In general, biofortified foods with relatively higher micronutrient density have higher total absorption rates than nonbiofortified varieties. Thus, evidence supports the focus on efforts to breed plants with increased micronutrient concentrations in order to decrease the influence of inhibitors and to offset losses from processing.

“…In Argentina Sosa, Martínez, Márquez, and Hough (2008) researched the adequate scale and location to measure food acceptability; and Sosa and Hough (2006) measured sensory acceptability of menus and snacks forming part of a food-aid program. Nuss et al (2012) studied the acceptability of maize (Zea mays) biofortified with provitamin A carotenoids among 3-5 year rural Zambian children. De Steur, Gellynck, Feng, Rutsaert, and Verbeke (2012) measured willingness to pay for folate biofortified rice using an auction procedure in the Shanxi Province of China.…”
