Researchers have been chasing the elusive links between gluten, infections, and major mental illness for decades. A new review recently came out as well, compiling the medical evidence that wheat proteins (including gluten) and other grains are a problem for some people, and how it could be a problem for many more. It also is a fair look at the limitations to what we know. It’s free full text, so go take a look:
The Dietary Intake of Wheat and other Cereal Grains and Their Role in Inflammation
Despite some hyperbolic coverage in Wheat Belly and slightly more convincing coverage in Grain Brain, there is, so far, quite a bit of smoke, but no fire outside a few case studies. Curt Dohan had quite a few papers back in the day (including this one), and much more recently Faith Dickerson, now armed with antibody titres, could be more precise (including in this paper). Yet in all those years of research, there was nothing definitive.
