|Ferritin concentrations in Caco-2 cells exposed to samples of maize only and maize-based diet digests; and Fe concentrations in samples of maize only and maize-based diet digests1|
|Tested sample||Caco-2 Cell Ferritin2, ng/mg of total protein||Fe concentration3, μg/g sample|
|High Fe maize only||22.51±0.9c||20.9 ±0.2c|
|Low Fe maize only||13.40 ±0.6d||20.0 ±0.9c|
|"High + Fe" diet||74.36 ±1.6a||65.3 ±0.9a|
|"Low + Fe" diet||56.89 ±1.1b||66.1 ±2.4a|
|"High" diet||6.55 ±0.5e||24.5 ±1.0b|
|"Low" Diet||1.31 ±0.4f||23.6 ±0.2bc|
1Values are means ± SEM, n = 6.
a,b,c,d,e,f Within a column (ferritin or Fe concentrations), means without a common letter differ, P < 0.05.
