Well Rusty, if you have been reading on here then you know that dh can come & go as it pleases & that means ON gluten or OFF gluten. If you have dh (& you never mentioned anything about itching) then the flare you had after adding the almonds, honey & spinach may not have been related to those foods at all. It could have been & then again it could not have been. That's what's the real bitch with dh is ~~~ trying to figure out what you're reacting to IF you're reacting to anything at all. In the beginning, I thought I was reacting to salicylates also but I found it was just coincidence that I began healing when I removed salicylates. I also believe I probably didn't need to be low iodine as long as I was but again, dh will make you nuts out of your ever loving mind until you imagine you are reacting to everything. A food journal can be of some help but again, with dh & the way it flares for no earthly reason; a food journal doesn't necessarily give you the answer & can in fact, cause you to remove foods you don't need to remove. The iodine is telling though. I tested my iodine reactions repeatedly & every time I added it, the rash flared, so it wasn't a fluke & I was indeed reacting to iodine which further cements the dh dx.
How long have you been on the GAPS diet? I would suggest adding one food per week & only one. Then add another for a week. And if you get a flare during these times, try to wait it out & see if you improve even though you're eating that food. That is going to be a torturous, long process. OR you can stop limiting your diet of sals & GAPS & just limit iodine for a while longer & then just eat & wait it out. DH can take years to get out of your skin. Ask me, I'm proof! I am now 2.5 years pristine gluten free & though I am 56,000% better; I still get places. They do not continually itch 24/7 & they subside in 1/2 day to 3 days & there are times when I go 4 days without 1 single itch. But it has been one hell of a long haul for me. The key is if you are sure & then you must be so dedicated that you stop listening to those little niggling voices that cause you to doubt literally every single thing you put in your mouth. Been there, done that! I assure that every tiny item I eat is gluten free beyond a shadow if a doubt. Beyond that, I EAT!!!!!! The only thing not in my diet yet is seafood. I'm not a huge fan of it anyway so it's no biggie to me. I could go for a little tuna fish or some salmon once in a while & I do dig lobster but other than that ~~~~ meh, I can do without it.
BTW, I had heart palpitations or rapid heart beat & that whole dizzy thing going on & while not high, my bp was borderline high where they were warning me I better get it down or go on meds, which was really weird for me. Gluten free fixed all that. Now they take my bp & it's back like it used to be ~~~ they remark on how chilled out I am @ age 57!
You are a 35 yr. old. You need nourishment more than chicken, broth & bananas. You can't stay on that for an extended period without doing some other form of damage to your body. Your body NEEDS nourishment to heal.
I think maybe the most important thing I could say to you is that this is a mental game you're playing. DH is the world champion at making you doubt & will take you down in a heartbeat if you aren't constantly on alert for it's mind benders. It will wiggle & worm it's way into your mind when you least expect it. Don't let it win. Do not let it make you insane & afraid to eat good nourishing food.
I will also say that eating out is playing Russian roulette. And that includes eating at friends & family. They do not know all the rules & unless & until they do then you put yourself at risk. BE STRONG. Take your own food wherever you go. Do not take any chances with this. This is how you will defeat dh. You defeat it by not risking any cross contamination & thereby being sure in your mind that you are not reacting to gluten contamination.
