Humans haven't stopped evolving in the 8000 years since grains were cultivated. It would seem logical that changes allowing grains to form an effective part of the diet would have occurred. Take the example of milk - humans in heavy cattle dependent parts of the world (ie: most everywhere except north east asia) produce enzymes allowing its digestion into adulthood. So can we now digest grain effectively?
For comparison: a mutation in one gene giving a 1% increase in survival chance will reach 50% saturation in a population in an average of 100 generations. For humans that's 2500 years or so.
What I'm saying is that if you don't have a genetic disposition to gluten intolerance you're likely to be perfectly ok with grain.
