Korwyn, I would dearly love to read your spiel you give guests which gets the point across. We have not had any guests as yet since i went gluten free slightly over 2 months ago but I have been racking my brain for what exactly to tell people the first time it comes up. I keep trying to think what will really get the point across.
OK. It goes something like this: Don't bring food over or I'll kill you!
No, seriously, I have a couple variations depending on if they know something about my 'food thing' or if they are totally in the dark.
Hi, <blah blah having a party blah blah or whatever>. We'll have tons of foods/drinks/snacks/etc so we really won't need any extra food. Besides, I don't know if you're aware, but I have some food related issues that are genetic and cause serious health problems if I come in contact even with trace amounts. So please don't worry about bringing any food, and in fact if you have something specific you like I can usually find a safe version of it to have! Whats your favorite (food/drink/finger food/etc) ?
That is kinda of a nutshell version. I vary it obviously depending on what we're doing, is it a group, is it a sit down full meal, etc. I've been surprised at how many people have asked me 'is it gluten/wheat' or some variation thereof ("oh is it that gluten stuff?" was one of my favorites). It actually gives me opportunities to talk to people about celiac disease and gluten (along with processed foods, gmo, how soy effects hormones, etc). I would guess that in the last three years now I have probably a dozen or more families/individuals where one or more person is now gluten free as a result of this.
