Comparisons between the feeding groups and over time for fecal iron, ROS, and inflammatory biomarkers at before and after introduction of complementary foods. Error bars indicate +/- 2 SE; comparisons by repeated measures ANOVA; (a) Average creatinine corrected F₂-isoprostanes in urine (n = 25). No significant differences between groups or over time. b Fecal iron in the three study groups (n = 77).*Significant difference (p < 0.05) over time. **Significant difference between the groups. c Total hydroxylated products in the three study groups (n = 66). *Significant difference (p < 0.05) over time. d Fecal calprotectin concentration in the three study groups (n = 43). *Significant difference (p < 0.05) over time
