Effects of standard diet and red meat-based diet with or without kimchi supplementation on the number of (A) aberrant crypt foci (ACF) and (B) mucin-depleted foci (MDF) in the colon of rats 120 days following the injection of 1,2-dimethylhydrazine (DMH, 20 mg/kg body weight). Data (n = 10) are expressed in mean ± SD. Different lettering indicates statistically significant difference among samples (p < 0.05). Saline: group of rats injected with NaCl solution (0.9%) and given standard diet. DMH: group of rats injected with DMH and given standard diet. RM: group of rats injected with DMH and given red meat-based diet. K-5%: group of rats injected with DMH and given standard diet with kimchi supplementation (5%). RM + K-5%: group of rats injected with DMH and given red meat-based diet with kimchi supplementation (5%). K-10%: group of rats injected with DMH and given standard diet with kimchi supplementation (10%). RM + K-10%: group of rats injected with DMH and given red meat-based diet with kimchi supplementation (10%)
