i note that in India they had frequent crop failures which let to famines and then a new wheat variety was invented and that seemed to help
BUT
this new variety of wheat hasproteins in it that humans have not evolved to digest
quoting from
http://www.wheatbellyblog.com/2012/03/the-wheat-lobby-smokescreen/
Whole grains of 2012 are also not the whole grains of 1950, the 19th century, the Bible, or pre-biblical times. Modern wheat, in particular, is genetically distant from its predecessors, thanks to the extreme genetic changes (
not genetic modification!) inflicted on wheat in the 1960s and 1970s in the name of increased yield-per-acre.
