It says oxalates may aggravate candida...

Thanks for that info. I noticed that in that link, it makes a direct comment on a connection between yeast (candida) and oxalates in the diet:

The link cites a program, in which some of the children (and I suppose this may work for adults too) who followed the low oxalate diet "improve in very surprising ways after getting off high oxalate foods. Gastrointestinal issues were improving.... Yeast issues were getting better."
