Effects of fructooligosaccharides on the absorption of iron, calcium and magnesium in iron-deficient anemic rats.
We investigated the effects of fructooligosaccharides (FO)-feeding on the absorption of iron (Fe), calcium (Ca) and magnesium (Mg) and on the biochemical parameters in Fe-deficient anemic rats. Fe-deficient anemic rats were made by feeding an Fe-deficient diet for 3 weeks. Then these Fe-deficient rats were fed an experimental diet that contained one of two levels of Fe (15 or 30 mg/kg diet), in...
متن کاملPromotive effects of resistant maltodextrin on apparent absorption of calcium, magnesium, iron and zinc in rats
BACKGROUND It has been reported that low-viscous and fermentable dietary fiber and nondigestible oligosaccharides enhance mineral absorption. Resistant maltodextrin, nonviscous, fermentable and soluble source of dietary fiber, has several physiological functions. However, influence of resistant maltodextrin on mineral absorption is unclear. AIM OF THE STUDY We conducted balance studies in rat...
متن کاملInhibition of food iron absorption by coffee13
Dual isotope studies were performed in iron replete human subjects to evaluate the effect of coffee on nonheme iron absorption. A cup of coffee reduced iron absorption from a hamburger meal by 39% as compared to a 64% decrease with tea, which is known to be a potent inhibitor of iron absorption. When a cup of drip coffee or instant coffee was ingested with a meal composed of semipurified ingred...
متن کاملOlfactory ferric and ferrous iron absorption in iron-deficient rats.
The absorption of metals from the nasal cavity to the blood and the brain initiates an important route of occupational exposures leading to health risks. Divalent metal transporter-1 (DMT1) plays a significant role in the absorption of intranasally instilled manganese, but whether iron uptake would be mediated by the same pathway is unknown. In iron-deficient rats, blood (59)Fe levels after int...
متن کاملThe effect of 'fibre-filler' (F-plan diet) on iron, zinc and calcium absorption in rats.
1. The availability of iron, zinc and calcium in a diet containing 400 g 'fibre-filler' (a mixture of bran, fruit and nuts, used in the F-plan diet)/kg diet (HF diet) was measured by whole-body counting in rats, using 59Fe, 65Zn and 47Ca as extrinsic labels, and compared with a diet of similar mineral content but no 'fibre-filler' (LF diet). Absorption of Fe and Ca was significantly higher from...
