I still think that people like us have a genetic predisposition to candida. There is some enzyme or peptide or other which we dont manufacture in our bodies which "normal" people do, that controls candida.
I've had four babies and in the last trimester of two of my pregnancies my candida symptoms simply disappeared. I think that the baby was manufacturing some substance and passed it into my bloodstream which protected me against candida.
That's why I will always have to stay on the candida diet.
