BACKGROUND: Lyophilized meat powder with iron-fortified wheat flour can be used to produce an infant porridge with bioavailable iron, but its acceptability and safety are unknown. OBJECTIVE: To evaluate the acceptability and safety of porridges containing lyophilized meat powder and iron-fortifie...

Datos nacionales e incluso departamentales de anemia y desnutrición crónica se recolectan con periodicidad. Es raro encontrar datos a nivel municipal del estado nutricional de una población, información necesaria para focalizar intervenciones. Un esquema conceptual se desarrolló, aplicó y válido....

The effect of processing (homogenization, lyophilization, acid-extraction) meat products on iron uptake from meat combined with uncooked iron-fortified cereal was evaluated using an in vitro digestion/Caco-2 cell model. Beef was cooked, blended to create smaller meat particles, and combined with ...

Background. Optimal feeding of infants and young children in developing countries includes daily feeding of animal-source foods. Objective. To evaluate constraints on the availability of animal-source foods at the community level, access to animal-source foods at the household level, and intake ...

Background Agricultural science can address a population's vitamin, amino acid and mineral malnutrition through biofortification - agronomy, plant breeding and biotechnology to develop crops with high nutrient contents. Biofortified crop varieties should be grown in areas with populations at ris...

OBJETIVO: Identificar zonas geográficas de América Latina y el Caribe para la biofortificación de cultivos básicos como frijol, maíz, arroz, yuca y batata, contribuyendo así a reducir las deficiencias nutricionales en la Región. MÉTODO: Se generó un sistema de información geográfica (SIG) que in...

Rapid-cycling recurrent selection has been implemented to produce cassava varieties that deliver provitamin A carotenoids to human populations that are affected by vitamin A deficiency. Rapid-cycling selection relies on quantification in just one plant per genotype. This study was conducted to a...
