You seem to say this under the common on this board assumption that candida occurs in people naturally and in a healthy person co-exists with everything else in the body without causing any problems. I think that couldn't be further from the truth. I got candidiasis sexually and there is no way I had that in my system before the way it tore me up after the infection. It must be pretty virulent having somehow made its way from the genitals to the intestine, putting holes there and then from there to other parts of the body through the bloodstream, giving me heart and eye pains now when I eat the wrong stuff.
