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...
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...
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.
Nonheme-iron absorption from a phytate-rich meal is increased by the addition of small amounts of pork meat

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...
Iron bis-glycine chelate competes for the nonheme-iron absorption pathway
Iron bioavailability iron absorption ferrous bis-glycine iron amino acid chelate iron fortification iron status
2016/12/19
Background: The enterocytic absorption pathway of the food fortificant iron bis-glycine chelate has been the subject of controversy because it is not clear whether that substance uses the classic...
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...
Adaptation in iron absorption: iron supplementation reduces nonheme-iron but not heme-iron absorption from food
Iron supplementation heme iron nonheme iron iron absorption fecal ferritin serum ferritin
2016/6/8
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...
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.
