This is not new. The woman in question got complete relief from her
schizophrenic symptoms, after many years of chronic, drug resistant
symptoms, on a ketogenic diet, but she could have done this on a
gluten-free, dairy free diet as well. There were two solid single blind,
crossover studies reported in 1969 and 1976, showing that such a diet led to
a faster recovery from schizophrenic symptoms (19, 20). Similarly, when a
schizophrenic patient in a locked ward developed diarrhea, celiac disease
was eventually diagnosed and that patient recovered from her symptoms of
both schizophrenia and celiac disease on a gluten-free diet (21). Just this
month, another group reported a rate of celiac disease that is 7 times that
of the general population among schizophrenic patients (based on tTG
testing). They also report that about one third of schizophrenic patients
show high levels of IgA anti-gliadin antibodies (22). Again, this is about 7
times the rate in the general population.  

There are many reports of the value of a gluten-free, dairy-free diet in
schizophrenia. Dr. Curtis Dohan blazed the trail many years ago, offering
substantial information and insight (1-19). It was his work that led
Christine Zioudrou to investigate gluten for the psycho-active peptides that
she and her group found in wheat (23).   However, mainstream psychiatry pays
no attention to such reports. The standard approach is to administer
anti-psychotic drugs that most patients find most unpleasant and often
discontinue. Gluten-free food manufacturers cannot afford to wine and dine
and indoctrinate physicians. It is terribly frustrating to see these data
either ignored or dismissed based on sloppy, grossly biased investigations.
One such study allowed the patients' relatives to bring food for patients on
weekend visits. Others did not eliminate some very obvious sources of
gluten. Still others use a variety of other methods to ensure that their
research produces the expected result. In the end, most will not consider it
because they are unable to believe that diet can have such a profound effect
on cognition and mental health.
