An Open Letter to Skeptical Health Care Practitioners
Yes, I get blisters from soy just as I would from gluten. It took an extremely strict elimination diet for me to figure it out. I stay awake at night sometimes wondering whether an IgA granular test for soy would test positive, but I know I could never find a doctor willing to test. I can hardly find a doctor who even knows what dermatitis herpetiformis is.
Might help with ease of digestion, and there is studies that show it helps in the breaking down of carbohydrates so it helps reduce gas, bloating, and indigestion, But not really helping much your immune system attacking your intestines trying to kill the gluten, Still going to get damage and stuff in the background.
I use it in making dairy free cheese, and sauces to give it that "bite" I also use it in baking in combination with baking soda subs and baking powder for rising gluten free and yeast free baked goods.
If flying I do not know, I normally take a car or train. And I bring chef kit with a griddle, and nordicware cookware. My thoughts, bring meal replacement shakes, jars of nut butters, and protein/nut bars,
Perhaps crackers? I know they make some gluten free ones (I can not consume most as I can not have carbs or grains). I honestly make Nut meal/butter porridge out of coconut and almond flour with almond butter. I add extracts and stevia for flavor and sweetener. Other thoughts for cooking in your hotel room. Noridicware makes microwave cookware, grill sheets, steamers, omelette makers (know you can not), rice cookers. etc. You can bring these in your luggage easier and just use the microwave or request one in your room. This way you can say have steamed fish and veggies, bacon, rice, porridge, etc. and fix it safely right in your room.
If you are celiac you HAVE to be gluten free no matter how inconvienent it may seem to you. Your body is clearly telling you to stop cheating on the gluten free lifestyle. If you need help with identifying where you can improve we are here to help in any way we can. You need to go and read the Newbie 101 thread at the top of the Coping section. It has a lot of valuable info for you. I hope your pain resolves soon but be aware that for some repeat glutenings can lead to the development of other autoimmune problems and for some the pain of each repeat glutening can increase as well.
