Thanks Destor, that's very interesting. I agree about wild vs cultivated grains, and modern wheat being worse than ancient wild grains. I think this is evidenced by the relative frequency of allergies to various grains; wheat and other gluten-containing cereals and corn are right up there, whereas allergy to tubers or millet is quite rare.
Also, use of grains found growing wild would have made them a much smaller percentage of the diet than the amount eaten on a neolithic or modern grain-based diet.
