I think that the obesity epidemic (which includes all the related diseases and fertility problems these days) is a teratogenic effect of grains and industrial processed foods. So no, I do not think adaptation will happen because the primary result seems to be accelerating ill-health and eventual reproductive failure in only a few generations. Perhaps we could soldier on with just mild illness if we followed Weston A. Price preparation methods, but I don't see us doing that as a species any time soon. We are likely to suffer some kind of global collapse before then in a denouement of our population explosion having been fueled by grain coupled with the general destruction of the biosphere that has supported our life thus far.
