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...
متن کاملStudies in Iron Absorption
P REVIOUS STUDIES showed that general systemic factors like the hemoglobin concentration, serum iron concentration, iron binding capacity, and the plasma iron clearance rate were not correlated to the intestinal iron absorption. Neither did parenteral iron treatment normalize high iron absorption.1 The purpose of the present study is to examine such local intestinal factors as the quantity and ...

Physiological control over iron balance is normally exercised through the regulation of iron absorption. Although it is known that the intestinal epithelium can reject unwanted dietary iron or absorb increased amounts when stores are low it is not known how iron crosses the epithelial cell or how this regulation is mediated. The principal factors which affect absorption are those acting in the ...

Iron is oxidized to the Fe3+ state no matter its original form when taken in orally. Gastric acidity as well as solubilizing agents such as ascorbate prevent precipitation of the normally insoluble Fe3+ . Intestinal mucosal cells in the duodenum and upper jejunum...
