Actually celiac isn't an allergy, it's a genetic intolerance. I don't think it's caused by parasites, at least not in my case. I dunno, I can't speak for anyone else. It certainly wasn't effected by the cleanses. I've done a handful. I did have some parasites and I noticed after one of the cleanses my blood sugar was a little better but thats the only thing I noticed. I think u might have misunderstood, I'm not reacting to soy, I seem to be reacting to the lack of soy, I felt great before when I was still eating it. I also noticed when I was eating soy my periods were regular and lighter, and without it they are like 6 weeks apart and painfully heavy.
