Inositol phosphates with different numbers of phosphate groups influence iron absorption in humans.
To improve iron absorption from cereals and legumes, degradation of inositol phosphates needs to be to less-phosphorylated inositoli phosphates than IP(3), while IP(5) has an inhibitory effect on iron absorption, whereas IP (3) and IP(4) in isolated form have no such effect.
Inhibition of haem-iron absorption in man by calcium
The present results strongly suggest that Ca interferes with the transport of Fe through the mucosal cell, andata late stage, is common for haem- and non-haem-Fe transport.
Maternal hormones linking maternal body mass index and dietary intake to birth weight.
It is proposed that low serum concentrations of IGFBP-1 represent a link between high BMI and increased fetal growth by increasing the bioavailability of insulin-like growth factor-I, which up-regulates placental nutrient transport.
Iron fortification of flour with a complex ferric orthophosphate.
The CFOP meets practical requirements of an Fe fortificant for flour well, with regard to both compatibility and bioavailability in humans, and it is shown that the relative bioavailability of CFOP varied from 30% to 60% when labeled wheat rolls were served with different meals.
Bioelectrical impedance: effect of 3 identical meals on diurnal impedance variation and calculation of body composition.
The ingestion of meals leads to an additive decrease in bioelectrical impedance and thus to a decrease in the calculated percentage of body fat.
No enhancing effect of vitamin A on iron absorption in humans.
The previously reported findings of a positive effect of vitamin A on nonheme-iron absorption in humans was not confirmed and the possibility that suboptimal vitamin A status influences the effect of dietaryitamin A on iron absorption is not excluded.
Minnesota leisure time activity questionnaire and doubly labeled water in adolescents.
PURPOSES To validate the energy expenditure estimated from The Minnesota Leisure Time Physical Activity Questionnaire (MLTPAQ) with total energy expenditure (TEE) measured by doubly labeled water
Accelerometry combined with heart rate telemetry in the assessment of total energy expenditure
It is concluded that the HR–ACC combination as well as ACC alone has potential as a method for assessment of TEE during free-living activities as compared with DLW.
