Iron Absorption from Infant Foods

Iron absorption from infant formula and iron-fortified cow's milk: experimental model in weanling rats.

OBJECTIVE To compare iron absorption from infant formula and iron-fortified cow's milk. METHODS Twenty-four weanling Wistar rats were maintained in metabolic cages during the whole experiment (10 days). On the first day, the animals were divided into three similar groups according to their weight, length, hematocrit and hemoglobin levels: 1) infant formula; 2) powdered whole cow's milk fortif...

Adaptation in iron absorption: iron supplementation reduces nonheme-iron but not heme-iron absorption from food.

BACKGROUND Results of cross-sectional studies suggest that in healthy people, iron absorption adapts to meet physiologic needs and stabilize iron stores, but this has not been adequately tested in longitudinal studies. OBJECTIVE We tested whether heme- and nonheme-iron absorption decrease in response to increased iron intake and whether iron stores reach a steady state. DESIGN In a randomiz...

How to ensure adequate iron absorption from iron-fortified food.

Iron absorption from an iron-fortified food can be considered adequate if the target population is able to maintain or improve iron status while consuming the fortified food as part of a normal diet. This is not always easy to achieve. In fact, iron is the most difficult mineral to add to foods and it is additionally difficult to ensure adequate absorption. This is because the most soluble and ...
