Protective role of probiotics and prebiotics in colon cancer
Fiber has been shown to be protective against colon cancer, but a recent study shed some doubt on this belief. However, it is commonly believed that this protective effect comes from the action of probiotics on soluble fiber, producing butyrate. I would love to see the bacterial environment of the GI tracts of the patients used in the study that showed no benefit from fiber, and re-evaluate the data.
