Prebiotics are substances that promote the growth of beneficial microorganisms thus, having health benefits as functional food. In the present study, comparative effect of prebiotics inulin and lactulose on 1,2-dimethylhydrazine dihydrochloride (DMH) induced procarcinogenic biomarkers in early colon carcinogenesis is described. It was found that aberrant crypt foci counts were significantly (p %26lt;0.05) less in both prebiotics + DMH treated group compared with DMH treated group, but percent reduction was maximum (p %26lt;0.05) in inulin + DMH treated group. The activity of (beta-glucuronidase and beta-glucosidase decreased significantly (p %26lt; 0.05) in animals belonging to inulin + DMH group compared with lactulose + DMH treated. The study suggests that prebiotic inulin may possess better prophylactic potential than lactulose due to reduced biomarkers of colon carcinogenesis in the initiation phase.
