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 کاملPromotive effects of resistant maltodextrin on apparent absorption of calcium, magnesium, iron and zinc in rats
BACKGROUND It has been reported that low-viscous and fermentable dietary fiber and nondigestible oligosaccharides enhance mineral absorption. Resistant maltodextrin, nonviscous, fermentable and soluble source of dietary fiber, has several physiological functions. However, influence of resistant maltodextrin on mineral absorption is unclear. AIM OF THE STUDY We conducted balance studies in rat...
متن کاملEffects of fructooligosaccharides on the absorption of iron, calcium and magnesium in iron-deficient anemic rats.
We investigated the effects of fructooligosaccharides (FO)-feeding on the absorption of iron (Fe), calcium (Ca) and magnesium (Mg) and on the biochemical parameters in Fe-deficient anemic rats. Fe-deficient anemic rats were made by feeding an Fe-deficient diet for 3 weeks. Then these Fe-deficient rats were fed an experimental diet that contained one of two levels of Fe (15 or 30 mg/kg diet), in...
متن کاملMathematical model of zinc absorption: effects of dietary calcium, protein and iron on zinc absorption.
A previously described mathematical model of Zn absorption as a function of total daily dietary Zn and phytate was fitted to data from studies in which dietary Ca, Fe and protein were also measured. An analysis of regression residuals indicated statistically significant positive relationships between the residuals and Ca, Fe and protein, suggesting that the presence of any of these dietary comp...
متن کاملINTESTINAL ZINC ABSORPTION IN DESFERROXAMINE-TREATED RATS
Desferroxamine (Desferal) is used tochelate iron in thalassemia, a disease of very high prevalence in various parts of lran. We have investigated intestinal zinc absorption in Desferal-treated rats which, in pilot experiments, showed low serum levels of both iron and zinc. Intraperitoneal administration of ten 0.5 g doses of Desferal (one injection every other day) to male rats produced sev...
