I wouldn't trust wiki, even if it was the only source in the world. Try going to the topic and typing in keifr will make young women/ men chase you down the street with desire. There is nothing to stop you form doing that, and It will live there for some indefinite amount of time till someone comes back and corrects it. How many people will read it before it gets corrected?

I wouldn't count on these probiotics (in the levels that they can be used by normal consumers) to be antimutagenic or any other claim of the like. If it were as simple as that, we'd all just drink kefir during our lives, and never get cancer.... and we all know it ain't so.
