A further understanding
This research served as the precursor for further examination of how gluten affects people who have schizophrenia. According to a study published in Schizophrenia Bulletin in 2011, researchers found that the subjects with schizophrenia possessed a much higher number of the same antibodies that are associated with celiac and/or gluten sensitivity.
Furthermore, in the September 2013 issue of The World Journal of Biological Psychiatry, a study of schizophrenic patients revealed increased levels of antibodies to gliadin, a gluten protein. The researchers compared 950 patients to the 1,000-member control group. As a result, they found that the odds for schizophrenics having anti-gliadin antibodies was 2.13 times higher. So this definitely shows a negative reaction to wheat among this population.
