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. Means with no letters in common are significantly different, P < 0.05. |
