Funny that this came up today, as my sponsor just mentioned during our meeting today that I shouldn't drink non-alcoholic beer, because it has a small amount of alcohol in it. Personally, I've already had it several times and hve not had any effects with it triggering cravings, etc. It was just the opposite -- each time was in social situations like BBQs where I brought the NA beer so I could carry around what looked like a beer and not have to be questioned by acquaintances as to why I'm not drinking (what they want to know is, am I pregnant, hahaha) -- but that really reduced my anxiety and helped me avoid drinking even when everyone around me was. So I think we each have to figure out what feels right for us.
Personally, I think cooked foods with alcohol aren't a problem because the alcohol burns off. Uncooked, like tiramisu for example, I avoid.
