Figuring out the foods that cause GI reactions can be very frustrating, and time consuming....
I would suggest starting with allergy testing. This may not give you the answers you need because many GI reactions are not due to IgE allergies... However some people have been able to eliminate the foods they tested positive to and had good results....
Because some people do respond to eliminating the top 8 allergens from their diet that might be a good second step... Try it for a couple of weeks and see if there is improvement.
Along with all of those steps, keep a food diary. Write down everything that goes into your mouth, include all ingredients in combination foods. Also write down any symptoms, no matter how minor. You may be able to pinpoint certain foods that seem to make your symptoms worse.
Although with eosinophilic diseases, the causes of the Gi problems can vary greatly, some of the most common trouble makers are Dairy, Soy, and eggs...
If you just want to eliminate a couple of things to try, those would be a great place to start.... But remember to keep that diary because no matter how determined we are to remember chances are we won't....
I don't know if any of you have been tested for pin worms... Their eggs are airborn, so anyone can become infected... The rectal itching was the main symptom I had years ago... The doctors were sure I couldn't have them, but my son did, and I was the one changing sheets, etc....
The way they had me test, was to use a piece of scotch tape on the rectum to capture the worms as they came out to lay eggs. That is when the itching takes place usually with pin worms... I had to do this in the dark since they come out in the dark.... Very simple test, bit embarassing, but so worth it to find out that yes I did have them and get treated...
