The document summarizes research on biofortification being conducted by the AgroSalud project to improve nutrition in Latin America and the Caribbean. The project aims to develop and promote staple crops with higher concentrations of key nutrients like iron, zinc and vitamin A. Researchers are evaluating these biofortified crops across several criteria to determine their potential nutrition impact and cost-effectiveness compared to supplementation and fortification. Initial results suggest various biofortified crops have higher nutrient concentrations and bioavailability, as well as acceptable sensory properties and positive nutrition outcomes for consumers.

Consumer Acceptability Biofortified Beans Conventional Beans ¿Do they discriminate between biofortified and conventional beans? ¿Do they prefer biofortified or conventional beans? 80 Consumers in Holguín, Cuba (Orlando Chaveco, Unidad de Extensión, Investigación y Capacitación Agropecuaria de Holguín, Cuba )
24. Consumer Acceptability After tasting a recipe prepared with both bean types, consumers discriminated between biofortified and conventional beans (Orlando Chaveco, Unidad de Extensión, Investigación y Capacitación Agropecuaria de Holguín, Cuba ) Biofortified Bean Conventional Bean

Ex-ante Cost-effectiveness Compared with WHO estimates of the cost-effectiveness of supplementation and fortification in Latin America, the biofortification of rice, beans and maize with (1) iron is more favorable, (2) zinc (rice, maize) is more favorable than supplementation and (3) zinc is less favorable than fortification.
