From: High-iron consumption decreases copper accumulation and colon length, and alters serum lipids
Effects of high-iron feeding on colon length and iron and copper concentration in feces and the small intestine of rats. Five-week-old, male, SD rats were fed one of six diets, which varied only in their iron and copper content for 5 weeks ad libitum. Colon length (A), image of colon length (B), iron concentration in feces (C), and the small intestine (D), copper concentration in feces (E), and the small intestine (F). The results are presented as means ± SDs; n = 10 per individual group. Data were analyzed by two-way ANOVA with Tukey’s post hoc test for further comparisons. Different letters indicate significant differences (P < 0.05) among the labeled means. L low; Ad adequate; H high
