Both me and my daughter are very sensitive re. gluten, and even more sensitive for milk/casein.
She has tried ghee but it was not okay, at least not that time.

If you google Karen Tripp, she has a candida website I stumbled upon some years ago. She says no leftovers unless heated, interesting. She has recipies on the net too, and she is not into dairy either. I think her site is still up, I have not checked lately.
She says or uotes others saying lots of things and even herbs and supplements have mold, and that is why people do not get better on a candida diet/taking supplemets to kill yeast.
I read all corn and peanuts are infested with mold too.

Some DR types are more sensitive to mold, at least that is what Dr. shoemaker seems to say, according to some forum postings I read.

If I check HLA DR types on the sikipedia page, DQ beta chain 05* can be DR1, DR2, DR10, DR14 and DR16. Enterolab says 0501 but one cannot really be sure if it actually is 0501, 0502, or 0503 I think?
