Okay, so sometimes it is really difficult to get friends and family to understand that you have to be careful about what you eat. This is not just some fad diet. Granted I will not go into anaphylactic shock, but I will feel horrible and be in pain for a few days afterward. For a Celiac who has ingested gluten, it keeps attacking their body but you don’t see it, they cannot reverse the process.
Yes, an infinitesimal amount can be a problem. Even breathing in flour particles in the air is a possible source of contamination for some.
Going out to eat can be a real pain, but It is getting a little easier. There are more restaurants etc. that are offering gluten free menus.
Unfortunately, when you are invited out to someone’s home you don’t have a menu to choose from and you can’t just leave if there is nothing for you to eat. You may have mentioned to them several times that you are gluten free, but they have never really understood what that means. Cross contamination is the worst culprit and many people are unaware as they do it. So we still have a lot of educating to do!
