An interesting study are the substantial differences between the wheat we eat today, “organic” or otherwise, and wheat in the wild or at the early stages of cultivation, way back when. These differences are believed to be a factor in the rise of celiac disease and “gluten sensitivity.” (I take no position on this.) What is undeniable, however, is that we are *not* consuming the same wheat our grandparents and great-grandparents did. Americans do not go out into the fields and see those “amber waves of grain” the patriotic song refers to — they see easily harvestable dwarf wheat. And wheat is everywhere, of course, in the modern Western diet.
