I was curious about this, as a relation has gluten intolerance. This reckons that the gluten content of wheat hasn't really changed:

And entertainingly this reckons increasingly industrialy generated wheat is now so devoid of any nutrients, even pigs won't eat it? http://www.grainstorm.com/pages/modern-wheat
Is it just me or is it becoming increasingly more difficult to get the truth on any matter, because you're wading through so many layers of human generated FUD (Fear, Uncertainty and Doubt)?
