I want to weigh in on this. A long time ago I tested allergic to wheat via skin prick test. I ignored it because no one told me what the symptoms were and frankly I have a lot of allergies to airborne things that distract me from lesser things. (I ignore a lot of allergies). One day I noticed that the joint pain I was experiencing was not there when I woke up but came on right after I ate a bowl of cereal. I determined it was not caused by the milk and that it was caused by the cereal. I tried avoiding wheat. I read up and found as SickofSickness said, you can't avoid it 95%, has to be 100% and wheat gluten is in everything. I began to wonder if I was celiac and I sent in for their book listing brands with and without gluten, I joined a local celiac club, and avoided wheat 100%. It did take care of joint pain, brain fog, mood problems, and to some extent inflammation. But invariably a little gluten would squeak in and I found I had become EXTREMELY sensitive to the least shred of wheat. The joint pain for the least of it - I could not go out with friends and eat or drink anything at all or it would completely destroy my mood to the point that I could not even fake having a good time. Huh. So I decided to get tested for celiac disease. I do not have it.
So then I decided it was not helping me to avoid wheat as I was becoming hypersensitive to it. It was about this time that the studies were coming out saying that zinc protects against the common cold and that the way it did so was the barrier method -- zinc "fills in the pores in the nose through which the rhino virus gets in". In other words, if you are short of zinc, your body tries to make do with the zinc you've got by stretching it via making larger pores. I reasoned that blood vessels are skin, thus the reason that zinc helps the capillaries in the eyes against macular degeneration, and that the intestines are skin, thus protecting against absorption of undigested food. It turns out that partially digested wheat that is absorbed into the blood stream is nasty stuff and known to cause brain allergies and joint pain. So I decided to go ahead and eat wheat but to supplement zinc and I did so at a high dose. Bam. The wheat intolerance went away.
However I would like to show you something I also consider very off about wheat. The Life Extension doctors say that they can keep all their patients' blodo pressures normal simply by having them avoid wheat:

I think wheat is not at all as healthy as we have been led to believe growing up. However I have no wish to be unusually intolerant to it so I do not avoid it anymore. I take quite a lot of zinc as my allergic rhinitis damages mucous membranes which it then takes quite a lot of zinc to repair. So I have to constantly guard against going wheat intolerant...I have to take a lot of zinc.
