There are helpful rules to establish a safe diet. It may take a long time to complete, but finding your safe foods to eat list and adhering to that list is the only way you can have a chance to manage your reactions. Haven’t checked lately, but there should be safe diet info on the net!

I found a couple of rules that help are:
Avoid prepared foods as their ingredients info are often not complete or available.
Do your own cooking and don’t rely on someone else.
Stop eating at restaurants.
Stick to minimum cooking with no sauces or herbs.
Once you are safe but want to try a new food, initially try a small amount minimally cooked - then wait 2 to 3 days before a second try. If you react on the second try, then that food is not safe. If you do not react on the second try, wait several weeks before you try again, if no reaction, then add that food to you safe list.

Finally, if your efforts at finding a safe diet seem to be endless, go gluten free. So called silent Celiac Disease suffers often don’t have classic CD symptoms as there are as many as 200+ symptoms related to CD. And to be certain stay gluten free for 6 months. If to do so dramatically reduces your reactivity, then explore the increasingly expanding CD info at various CD organization websites. Or, if you have a Celiac Center in your area reach out to them to help you determine your best way to manage your symptomologies!
