All: There seem to be a number of articles on Noncoeliac Wheat Sensitivity. Also a TED talk.
Additionally; connections between this sensitivity and neurological damage, re: lesions and the occurrences of Schizophrenia, Autism Spectrum Disorder and Essential Tremors. Time, maybe, to either deal with the inconvenience of maintaining a completely wheat-free diet or putting up with all the disorders that it seems to be creating. It begins to look as if going to sourdough may not be enough. I've tried what they call 'gluten-free'. It's disgusting and disproportionately expensive, as are any products under the 'special' diet label. People try the Paleo Diet. Need to investigate.
