Please note that this poll is about PREbiotics (substances that feed bugs), not PRObiotics (bugs). We've been discussing this topic on the resistant starch thread. Initially, people were experimenting with resistant starch but rapidly tried lots of other prebiotics. Sometimes, people come a cropper. I'd like to know whether they get back to baseline and if so, how long that takes. That is, I'm trying to assess how risky it is to try a range of prebiotics. Take the poll!
