Hi Eve,
our materiali has all of them (:wink:)
Now I'd like to give you back the question, in which organs do you see diarrhea or nausea or stomach ache appear, and what do we know about their emotional themes? (There is a search function in both the wiki and in the book...)

I'd go about like this: "So this food is making your body react with X. That means that X is a vulnerable part of you right? It can't do its job well when that food is around. What do you feel the job of X is?" 
In that way I can let them find the connection themselves. And can give some biological explanation or examples if needed.
Does that make sense?
