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...
Parenteral nutrition results in impaired lactose digestion and hexose absorption when enteral feeding is initiated in infant pigs
amino acids glucose galactose
2017/1/4
Preterm infants often receive total parenteral nutrition (TPN) before enteral feeding. Although TPN has been linked to mucosal atrophy, its effects on intestinal digestion, absorption, and metabolism ...
Measurement of magnesium absorption and retention in type 2 diabetic patients with the use of stable isotopes
absorption excretion retention
2017/1/4
Magnesium deficiency has been associated with type 2 diabetes and may reduce insulin sensitivity and impair glucose tolerance. The etiology of magnesium depletion in diabetes is unclear. Animal studie...
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.
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 ...
Efficiency of calcium absorption is not compromised in clinically stable prepubertal and pubertal girls with cystic fibrosis
bone calcium stable isotopes
2017/1/3
Reduced bone mass is common in both children and adults with cystic fibrosis (CF) and may be a consequence of inadequate calcium absorption. The effect of CF on intestinal calcium absorption and reten...
Inhibition of cholesterol absorption by phytosterol-replete wheat germ compared with phytosterol-depleted wheat germ
Diet human studies phytosterols
2017/1/3
The objective was to establish whether the selective removal of phytosterols from wheat germ would increase the cholesterol absorption measured from test meals composed of wheat germ muffins.
Cofortification of iron-fortified flour with zinc sulfate,but not zinc oxide,decreases iron absorption in Indonesian children
Food fortification iron absorption stable isotopes zinc absorption children Indonesia
2016/12/19
Background: Iron deficiency is a major nutritional concern in developing countries, and food fortification is a common strategy to treat it. In Indonesia wheat flour is fortified with 60 mg Fe/kg...
Zinc absorption from a low–phytic acid maize
Plant breeding maize phytic acid zinc ratio of phytic acid to zinc zinc absorption
2016/12/19
Background: Phytic acid reduction in cereal grains has been accomplished with plant genetic techniques. These low–phytic acid grains provide a strategy for improving the mineral (eg, zinc) status...
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...
Age and copper intake do not affect copper absorption,measured with the use of 65Cu as a tracer,in young infants
Copper absorption human milk infants copper supplementation 65Cu
2016/12/19
Background: Copper homeostasis involves a high degree of regulation in which changes in absorption and biliary excretion are the main mechanisms. Whether neonates and small infants can make these...
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...
Calcium and zinc absorption from lactose-containing and lactose-free infant formulas
Calcium absorption zinc absorption stable isotopes mineral requirements infant nutrition mass spectrometry infant formula breast milk human milk
2016/12/19
Background: Calcium absorption is enhanced by the presence of lactose, but the quantitative significance of this effect in infant formulas is uncertain. It is also not known whether lactose affec...
Evidence for lack of absorption of soy isoflavone glycosides in humans,supporting the crucial role of intestinal metabolism for bioavailability
