    • Bioavailability of elemental iron powder in white wheat bread 

      Walter, Tomas; Pizarro Aguirre, Fernando; Abrams, Steven A.; Boy, Erick (NATURE PUBLISHING GROUP, 2004-03)
      Objective: Iron fortification of wheat flour is widely used. In most cases, elemental iron powders are utilized as fortificants due to their lower cost and few, if any, sensory problems. However, their bioavailability is ...
    • Breast-feeding and mental and motor development at 5 1/2 years 

      Clark, Katy M.; Castillo, Marcela; Calatroni, Agustín; Walter, Tomas; Cayazzo, Marisol; Pino Zúñiga, Paulina; Lozoff, Betsy (ALLIANCE COMMUNICATIONS GROUP DIVISION ALLEN PRESS, 2006-04)
      Objective: Breast-feeding is associated with better child development outcomes, but uncertainty remains primarily due to the close relationship between breast-feeding and socioeconomic status. This study assesses the issue ...
    • Caco-2 intestinal epithelial cells absorb soybean ferritin by mu(2) (AP2)-dependent endocytosis 

      San Martín Rovirosa, Carol; Garri, Carolina; Pizarro Aguirre, Fernando; Walter, Tomas; Theil, Elizabeth C.; Núñez González, Marco (2008)
      Iron deficiency, a condition currently affecting similar to 3 billion people, persists in the 21st century despite half a millennium of medical treatment. Soybean ferritin (SBFn), a large, stable protein nanocage around a ...

    • Iron deficiency in infancy: applying a physiologic framework for prediction 

      Lozoff, Betsy; Kaciroti, Niko; Walter, Tomas (AMER SOC CLINICAL NUTRITION, 2006-12)
      Background: Infants aged 6-24 mo are at high risk of iron deficiency. Numerous studies worldwide have sought to identify predictors of iron deficiency in this age group. Objective: The objectives of the study were to apply ...
    • The poor bioavailability of elemental iron in corn masa flour is not affected by disodium EDTA 

      Walter, Tomas; Pizarro Aguirre, Fernando; Boy, Erick; Abrams, Steven A. (AMER INST NUTRITION, 2004-02)
      The most sustainable way to eradicate iron deficiency is through food fortification. Elemental iron powders are commonly utilized as fortificants due to their low cost and few sensory problems. However, their bioavailability ...
