The way I look at it is that candida thrives on certain types of molds/fungi more than others; for instance mildew is one that it likely thrives on. Certain Japanese mushrooms it may not be able to thrive on very well.
I lived in a very moldy apartment and you can find tons of stories about how mold toxicity can lead to candida overgrowth. Same thing happened to my wife as well. We both likely had high candida levels before living in these apartments but it totally caused the candida to explode over time.
