Modeling tool for calculating dietary iron bioavailability in iron-sufficient adults
bioavailability model dietary iron absorption dietary iron intake dietary reference values iron iron bioavailability iron intake serum ferritin
2018/11/14
Background: Values for dietary iron bioavailability are required for setting dietary reference values. These are estimated from predictive algorithms, nonheme iron absorption from meals, and models of...
The high prevalence of iron deficiency in infants and in
women of reproductive age and more recent concerns about iron
overload in genetically susceptible persons emphasize the potential
importance...
Cofortification of ferric pyrophosphate and citric acid/trisodium citrate into extruded rice grains doubles iron bioavailability through in situ generation of soluble ferric pyrophosphate citrate complexes
iron bioavailability iron fortification extruded rice ferric pyrophosphate trisodium citrate iron deficiency
2018/11/29
Background: Iron fortification of rice is a promising strategy for improving iron nutrition. However, it is technically challenging because rice is consumed as intact grains, and ferric pyrophosphate ...

An iron-dependent cyanobacterial bioreporter (Synechococcus strain KAS101) was used in unison with sizefractionated iron content (.0.45, ,0.45, ,0.02 mm), and chemical characterization of iron complex...
Initial uptake and absorption of nonheme iron and absorption of heme iron in humans are unaffected by the addition of calcium as cheese to a meal with high iron bioavailability
Heme iron nonheme iron whole-body counting whole-gut lavage mucosal uptake absorption retention serosal transfer humans calcium erythrocyte incorporation
2016/12/19
Background: Quantitative data on the mucosal uptake and serosal transfer of nonheme-iron absorption in humans and the effects of calcium on these components are limited.Objective: Our object...
Iron bioavailability from iron-fortified Guatemalan meals based on corn tortillas and black bean paste
Iron bioavailability stable isotopes ferrous fumarate corn tortillas Na2 EDTA disodium ethylenediaminetetraacetate NaFeEDTA sodium iron ethylenediaminetetraacetate girls Guatemala corn masa flour
2016/12/17
Background: Corn masa flour is widely consumed in Central America and is therefore a potentially useful vehicle for iron fortification.Objective: The goal was to evaluate the bioavailability...
Iron bioavailability in infants from an infant cereal fortified with ferric pyrophosphate or ferrous fumarate
Iron infants ferrous fumarate ferric pyrophosphate, bioavailability stable isotopes infant cereal
2016/6/7
Background: Infant cereals are commonly fortified with insoluble
iron compounds with low relative bioavailability, such as ferric
pyrophosphate, because of organoleptic changes that occur
after add...
Estimation of nonheme-iron bioavailability from meal composition
Iron bioavailability absorption biochemical composition nonheme iron phytic acid phytate ascorbic acid, vitamin C animal tissue content
2016/6/3
Background: Considerable data are available on the individual
effects of dietary factors on nonheme-iron absorption, but
their combined effect when they are present in the same meal
is not known.

Adaptation of iron absorption in men consuming diets with high or low iron bioavailability
Gastrointestinal adaptation nonheme-iron absorption heme-iron absorption dietary bioavailability iron requirements serum ferritin fecal ferritin ascorbic acid meat, phytic acid tea men
2016/6/3
Background: Short-term measurements of iron absorption are
substantially influenced by dietary bioavailability of iron, yet
bioavailability negligibly affects serum ferritin in longer, controlled
