Interesting concept though I do not believe it. Putting another artificial thing, a poison , in the body cannot help things. I might wonder if you are feeling relief because you are feeding them. I went thru that for years when I thought my blood Sugar was the reason for my problems. Drinking some milk or eating something like carrot sticks made my symptoms completely disappear . This went on for maybe 2 years. But once that curtain dropped, it got ugly.
As long as you feed them they are happy and will not bother you until you get to a point where there is so much of it in you that you can't possibly feed them all. Then they get angry. One day you are fine the next day your world can crumble.
So I would be really careful about what you think is killing candida. And it is really tricky to figure out. I get the same symptoms from die off as I do from eating something that is bad on the candida diet ( though I have not eaten anything wrong in about 2 years). But you can feel die off that is actually because they were fed.
