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.
Body iron stores and their determinants in healthy postmenopausal US women
Iron ferritin alcohol
2017/1/5
Using blood samples collected in 1989–1990, we measured plasma ferritin concentrations in 620 healthy postmenopausal women aged 44–69 y who participated in the Nurses’ Health Study. Food-frequency que...
Iron supplements inhibit zinc but not copper absorption in vivo in ileostomy subjects
Ileostomy zinc copper
2017/1/4
Iron supplements may inhibit intestinal zinc and copper uptake because these elements may compete for binding to a transporter molecule (divalent metal transporter 1) that is located on the apical sid...
Milk folate but not milk iron concentrations may be inadequate for some infants in a rural farming community in San Mateo, Capulhuac, Mexico
Iron status folate status lactation
2017/1/4
We examined the prevalence of inadequate iron and folate status among lactating Otomi women and determined to what extent their iron and folate nutriture influenced the milk concentrations of these nu...
Iron supplementation during pregnancy, anemia, and birth weight: a randomized controlled trial
Iron deficiency anemia iron supplementation
2017/1/4
We tested the hypothesis that administration of a daily iron supplement from enrollment to 28 wk of gestation to initially iron-replete, nonanemic pregnant women would reduce the prevalence of anemia ...
New evidence that iron supplementation during pregnancy improves birth weight: new scientific questions
iron supplementation birth weight
2017/1/4
Anemia is extremely common in pregnant women. It is particularly high in areas of the world that also have high rates of low birth weight (LBW). Although conventional wisdom suggests that poor materna...
Bioavailability of iron, zinc, and other trace minerals from vegetarian diets
Iron zinc copper
2017/1/4
Iron and zinc are currently the trace minerals of greatest concern when considering the nutritional value of vegetarian diets. With elimination of meat and increased intake of phytate-containing legum...
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.
Regular consumption of NaFeEDTA-fortified fish sauce improves iron status and reduces the prevalence of anemia in anemic Vietnamese women
Iron food fortification anemia
2017/1/3
Fish sauce is consumed daily by a large proportion of the Vietnamese population and could therefore be a potentially useful food vehicle for iron-fortification programs.
Absorption of zinc from wheat products fortified with iron and either zinc sulfate or zinc oxide
Iron zinc wheat
2017/1/3
Several chemical forms of zinc have been proposed for food fortification, but information is needed on their absorption from common cereals having varied phytate content.
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 ...
Ascorbic acid from lime juice does not improve the iron status of iron-deficient women in rural Mexico
Iron deficiency bioavailability ascorbic acid
2017/1/3
Two rural Mexican populations were randomly assigned to an AA or a placebo group, each with 18 iron-deficient women. The AA group was given 500 mL limeade containing 25 mg AA twice a day, 6 d/wk, for ...
Effects of weaning cereals with different phytate contents on hemoglobin, iron stores, and serum zinc: a randomized intervention in infants from 6 to 12 mo of age
Infants cereals iron
2017/1/3
The objective was to investigate whether either an extensive reduction in the phytate content of infant cereals or the use of milk-based, iron-fortified infant formula would improve iron and zinc stat...
Efficacy and tolerability of low-dose iron supplements during pregnancy: a randomized controlled trial
Iron pregnancy iron deficiency
2017/1/3
Iron deficiency anemia (IDA) is common in pregnant women, but previous trials aimed at preventing IDA used high-dose iron supplements that are known to cause gastrointestinal side effects.
