Iron Deficiency
Relative Contributions of Red Cell Catabolism and Dietary Absorption to Fetal Iron Accretion During Pregnancy
The two specific aims of this study are 1) to assess the relative contributions of two major maternal iron sources (i.e. dietary iron intake and red cell catabolism) at supplying iron to the fetus, and 2) to determine the impact…

Anemia, Iron-deficiency
The Effect of Human Milk Oligosaccharides and Galacto-oligosaccharides on Iron Absorption in Kenyan Infants
Effective and safe strategies to deliver iron to infants and young children in Sub-Saharan Africa are urgently needed. One potential strategy to improve safety of iron fortification is to limit the total amount of unabsorbed iron…
