You mentioned that white rice is pretty innocuous b/c it has the bran (which contains lectin) removed in the polishing process. What about white wheat flour? Does it have the toxic stuff from wheat removed or is it still harmful b/c of the gluten? What about tapioca starch? I am also finding it hard to find beef or chicken broth that does not have hydrolyzed yeast..any suggestions or do i have to make my own from bones?
