I've been meaning to post about the gluten schizophrenia paper in Nutrition and Metabolism, prompted by the paper itself, a forward from Bloggeier and now a reminder on the THINCS formum by Bogdan. But it turned in to an epic with lots of threads to interweave so, while I get it sorted, here's a quick one liner on the joys of a gluten based diet that I can fit in over a coffee break now I've run out of filler and floor board timber.
Take one adult established schizophrenic with recent onset diarrhoea and weight loss. For some reason do a SPECT scan to look at the blood flow within their brain and note that it is abnormal in the left frontal lobe.
Place on gluten free diet.
Re-scan a little while later and re-biopsy the gut.
All cured, including the "schizophrenic" disorder.
You don't have to be mad to eat bread, but you might end up that way!
BTW it's possible to speculate whether the blood flow is a vascular phenomenon due to the gluten affecting the arteries in the brain or a hypoperfusion due to abnormal brain metabolism, ie a direct neural effect. I'd never really considered that the gluten effects on the brain might be vascular...
