Abstract

ABSTRACT - The introduction of biofortified crops like beans with higher iron content is a useful tool in preventing diseases such as anemia. The biofortification aims to reach the root of the problem of malnutrition, targets the neediest population, uses embedded distribution mechanisms, is scientifically feasible and effective in terms of cost, and complements other ongoing interventions to control micronutrient deficiency. Thus the measurement of mineral absorption is essential to enable the use of biofortified crops. This study evaluated the iron bioavailability of common bean varieties BRS Estilo and iron biofortified BRS Pontal in man through reliable techniques and have not yet used in Brazil. The beans used was produced by EMBRAPA / Agro Food. Subjects and Methods: The study included 29 young adult volunteers divided into 2 groups: Group CB (13 subjects) received 100g of common beans (BRS Estilo) cooked labeled with iron58 (58Fe) and Group BB (16 patients) received 100g biofortified beans (BRS Pontal), cooked and labeled with iron58 (58Fe). The next day they receive the reference dose of ferrous sulfate enriched iron-57 (57Fe). After consumption, an isotopic evaluation of iron was conducted for measurement of iron incorporation into erythrocyte. Results: The iron absorption was evaluated by isotopic ratio and did not differ between the groups.2015evalueted [i.e. evaluated]. Título e texto em Inglês.
