Green tea or rosemary extract added to foods reduces nonheme-iron absorption
green tea rosemary radioisotopes
2016/6/13
Phenolic compounds act as food antioxidants. One
of the postulated mechanisms of action is chelation of prooxidant
metals, such as iron. Although the antioxidative effect is desirable,
this mechani...
Improving iron absorption from a Peruvian school breakfast meal by adding ascorbic acid or Na2EDTA
Iron iron absorption stable isotope
2016/6/12
Iron-fortified school breakfasts have been introduced
in Peru to combat childhood iron deficiency.
Effect of ascorbic acid intake on nonheme-iron absorption from a complete diet
nonheme-iron ascorbic acid
2016/6/12
Ascorbic acid has a pronounced enhancing effect
on the absorption of dietary nonheme iron when assessed by
feeding single meals to fasting subjects. This contrasts with the
negligible effect on iro...
Inositol phosphates with different numbers of phosphate groups influence iron absorption in humans
Phytate inositol phosphates iron absorption
2016/6/1
Inositol hexaphosphate (IP6) is a well-known
inhibitor of iron absorption, whereas the effects of the less-phosphorylated
derivatives of IP6 are less known.
Nonheme-iron absorption, fecal ferritin excretion, and blood indexes of iron status in women consuming controlled lactoovovegetarian diets for 8 wk
Nonheme-iron absorption bioavailability iron status
2016/5/31
The characteristics of vegetarian diets suggest
that these diets would have lower dietary iron bioavailability
than nonvegetarian diets, but there is no evidence of iron deficiency
in vegetarians.
Influence of prenatal iron and zinc supplements on supplemental iron absorption, red blood cell iron incorporation, and iron status in pregnant Peruvian women
Stable isotopes iron zinc
2016/5/30
We aimed to examine the influence of iron status on
iron absorption during pregnancy by measuring supplemental
iron absorption, red blood cell iron incorporation, and iron status
in pregnant women.
Production of stable-isotope-labeled bovine heme and its use to measure heme-iron absorption in children1,2,3,4
Iron absorption zinc absorption heme iron stable isotope children
2008/12/11
Background: The use of stable isotopes has provided valuable insights into iron absorption in humans, but the data have been limited to nonheme iron. Objective: Our objectives were to produce heme iro...
Degradation of phytic acid in cereal porridges improves iron absorption by human subjects
Iron absorption phytic acid cereal porridges
2016/12/30
Phytic acid in cereal-based and legume-based complementary foods inhibits iron absorption. Low iron absorption from cereal porridges contributes to the high prevalence of iron deficiency in infants fr...
Nonheme-iron absorption from a phytate-rich meal is increased by the addition of small amounts of pork meat
meat pork phytate
2016/12/27
Muscle tissue from various sources is known to promote nonheme-iron absorption. However, systematic studies of the dose dependency of this effect of meat on iron absorption from an inhibitory meal wit...
No enhancing effect of vitamin A on iron absorption in humans
Vitamin A retinyl palmitate iron absorption
2016/12/27
Vitamin A and β-carotene were recently reported to enhance iron absorption by counteracting the inhibitory effect of phytic acid in cereal-based meals and of polyphenol-containing beverages on nonheme...
Iron supplementation during infancy—effects on expression of iron transporters, iron absorption, and iron utilization in rat pups
Rat pups infants divalent metal transporter 1
2017/1/5
Studies conducted in human infants suggest developmental changes in the regulation of iron absorption; however, little is known about the molecular mechanisms regulating iron absorption during infancy...
High-, but not low-bioavailability diets enable substantial control of women’s iron absorption in relation to body iron stores, with minimal adaptation within several weeks
serum ferritin fecal ferritin ascorbic acid
2017/1/5
Adaptation of iron absorption in response to dietary iron bioavailability is less likely in premenopausal women, who generally have lower iron stores, than in men.
The efficacy of a local ascorbic acid–rich food in improving iron absorption from Mexican diets: a field study using stable isotopes
Iron absorption bioavailability ascorbic acid,
2017/1/4
One potentially sustainable approach to improving iron status at the community level is to encourage the consumption of local ascorbic acid–rich foods, in conjunction with meals high in nonheme iron.
Iron absorption from fish sauce and soy sauce fortified with sodium iron EDTA
Iron absorption stable isotopes
2017/1/3
The objectives were to evaluate iron absorption from NaFeEDTA-fortified fish sauce and soy sauce against a reference fortificant (FeSO4), to compare iron absorption from NaFeEDTA-fortified fish sauce ...
