So, for example, I should forgeo usual practice and clear the menu with you beforehand, rather than just take the list of Becky-food-requirements I have and work it out from that?

Oh, no, not if you don't want to.

Anyway, I think that when you asked me, it was lent and that's a subset of the things I'm eating out-of-lent (the only ones I kept up properly since the end of lent are no chocolate and no caffeine, but they're an addiction thing as well as a tummy thing) and so would likely be moderately low risk to my tummy.
