Soy is one of the major allergens so it might be a good idea to try eliminating that next. If eliminating the soy doesn't do the trick, you might want to try those processed grain containing cookies and pretzels next. There is that Tricia Thompson study of gluten-free grains (and soy) sometimes being contaminated. https://www.glutenfr...g/blog.php?id=6
There is also the gluten contamination elimination diet for those with ongoing symptoms: http://www.biomedcen...1471-230X/13/40
It consists of: "brown and white rice; all fresh (no frozen, canned or dried) fruits, vegetables and herbs; fresh meats, poultry, fish and other non-processed protein sources. Unflavored, unseasoned dairy products are introduced on week 4. Allowed condiments are oils, vinegar (excluding flavored and malt vinegars), honey and salt. Allowed beverages are 100% fruit/vegetable juices, Gatorade, milk, water, and gluten-free supplemental formulas such as Boost and Ensure. All cereal grains aside from rice are prohibited. Processed cheeses, lunch meats, ham, bacon or other such processed, self-basted or cured meat products are not allowed. Lastly, a gluten-free multivitamin/mineral daily supplement is recommended and prescription medication (verified as gluten-free) is continued."
I hope that things improve soon.
Thank you: that elimination diet sounds like it might be very helpful.
