Note on FOS. I have been told that I can not take it since some bad bacteria can feed on it. FOS (fructoolligosaccharides) is feed on by citrobacter species, which I had a problem with. So I should avid it. I am actually still taking a fiber supplement with FOS in it because I cant find a fiber supplement that is gluten and wheat,yeast, and dairy free, that has insoluble and soluble fiber, which is needed in a fiber supplement. If anyone knows of a fiber supplement I would great appreciate it. Though I tend to do better with capsules because I cant get the thick fiber drinks down my throat.
