I can say avoidance is the best method, eg eat at home to have better control of what is in your food. It took me awhile to do that but in my town we have a gluten free allergen free restaurant I <3. ! but after having to retool my diet getting rid of other grains I can't really go there. But as of once the problematic food item has been eaten, I go for kombucha for probiotics and avoid foods that could cross react.. I tend to eat lighter foods and grab as many zzzz's I can. plus peppermint tea helps chill me out. I wish there was a way to soften and shake it immediately, but alas nein, sadly.
I am determined to find an answer. I shall keep looking. I've contacted several organizations and will be getting in touch with Dr. Alessio Fasano's office on monday to see if they know of anything. I know about his medication for blocking the effects of zonulin but I'm not about to go on medication for the rest of my life. I need something that can be taken on an as-needed basis when accidental gluten exposure occures.
