Ferritin concentrations in Caco-2 cells exposed to samples of beans only (whole bean) and bean-based diets
| Tested sample 1 | Ferritin (ng/mg of protein) |
|---|---|
| “Standard Fe” bean only (59 μgFe/g bean) |
2.31 ± 0.11c |
| “Biofortified Fe” bean only (88 μgFe/g bean) |
2.19 ± 0.14c |
| “Standard Fe” bean-based diet (39 μgFe/g diet) |
2.97 ± 0.10b |
| “Biofortified Fe” bean-based diet (53 μgFe/g diet) |
2.75 ± 0. 09b |
| Baseline2 | 3.28 ± 0.139a |
1Caco-2 bioassay procedures and preparation of the digested samples are described in the materials and methods sections.
2Cells were exposed to only MEM growth media without added food digests and Fe. Values are means ± SEM, n = 6.
a,b,c Within a column, means without a common letter are different, P < 0.05.
