I'm just avoiding gluten as much as possible. Unfortunately my food sensitivity is nonspecific so it pertains to all grains, not just the glutinous ones but also oats (extremely similar) and perhaps even rice. I've succumbed to eating rice a few days ago and will do again tomorrow coz I just dig Indian food (it's on a special).
I can't say I read any specific source but I've been toying with the idea of starting an elimination diet. I've not yet mustered the courage to do it, as it's awfully restricted:

When thinking about it longer & longer, it was a bit too much. After all, can't imagine life without eggs. And they do allow nuts, but these can be allergenic too.
Perhaps a detection diet would be a lot easier.
Detection diets in Google.
I do know for instance that stress makes intolerances worse. Also, a long withdrawal period can make things both worse (allergies) and better (intolerances). I've had chickpeas last week and this caused rather severe stomach cramps.
Ate peanut butter that I hadn't touched in over a month this weekend , and was itching all over! The new peanut butter jar I've opened since then didn't cause trouble.
But gluten definitely does bad things to both memory and joint function. The latter I understand: there's a pretty bad inflammation reaction (leaky gut yada yada) but the memory loss?
In layman's terms the Eades did a pretty good job in their Protein Power Life Plan.
Trouble is, how do you get in enough carbs if going too low causes problems for adrenal fatigue & thyroid. Mainly fruit as well as tuberous starches/veggies like carrots, potatoes, pumpkins, manioc, yam, cassave. I'm sure ljk will be able to tell you more.
