If they are symptom free and it's only detectable through tests, why stop eating wheat?
Thanks for the link.
I have heard theories that a return to diets that were standard in one's country of origin even 200 years ago makes one feel much better. It isn't the same for everyone as would be implied by the theory that we need to return to a universal hunter-gatherer diet to be healthy -- northern Europeans developed under different conditions than did southern Europeans than did people from China, and one can safely assume that diets have been honed and adjusted over the centuries within each culture in a way that promotes feelings of health and well-being.
I have also heard interesting studies that seem to indicate that people who are around domestic livestock regularly are healthier than those who aren't -- the theory being that we developed together, and our immune systems mutually benefit. It would seem certain that the rapid changes of modern society are not good for our minds or our bodies...
Of course one can get pretty extreme about anything. The keys are to pay attention to major known intolerances (celiac, lactose intolerance, etc...), to pay attention to one's own diet and try to spot things that seem to help or hurt, and to eat as naturally as possible. (Says the guy who just downed a package of Cherry Nibs)...
I'm always fascinated by the anecdotal reports of the incredibly good health, long lives, alertness, and youthful appearance of ascetic monks in places like Mt. Athos.
