Help? Tips on making good food choices during vacation

[Guest guest]

Hi,

I'm newly diagnosed gluten intolerant (11/08), very sensitive, and the meds

aren't working anymore to control symptoms when I do get glutened.

Next month I plan to take a vacation to Mexico. I haven't decided exactly where

yet but I'm leaning towards Cabo or Cancun. I'm going to make a little card for

myself in Spanish explaining my issue, but I'm curious how other travelers have

dealt with the food the issue while away. Any tips? Any foods that I should stay

away from there, that happen to be safe here? Has anyone has success with all

inclusive resorts?

Thanks in advance for any information!
