Next week I leave for London, England for 1 week, and a tour of Italy for 2 weeks. We'll see how eating gluten-free is like in both places.
I've heard that there are many gluten-free options in Italy since many Italians have Celiac disease. I don't speak Italian, but have an allergy phrase book, and also a business-card sized description of what I cannot eat (with some suggestions of what I can eat) in Italian.
If this is helpful for anyone, this is what an Italian friend wrote up for me:
Soffro di una forte allergia al glutine, per cui NON posso mangiare nessun tipo di frumento, segale, orzo o malto (niente pasta, pizza, pane, fritto impanato, etc.).
Posso invece mangiare prodotti elaborati dal mais, dal riso e dalla patata.
