I have Schizophrenia and Autism in my family. Both have been affected by diet. Gluten, dairy, preservatives, artificial dyes, histamines, etcl. have been troubling for my brother with Autism. He has severe food allergies though. My aunt, who is Paranoid Schizophrenic and Bipolar has always showed improvement with the removal of dairy and gluten, but has not sustained the diet. I suggest keeping a food diary… and writing down your symptoms, mood, etc. after every meal or snack. I don’t necessarily think ALL individuals with mental health issues should diet or remove anything from their diet, but I have seen the benefits for some first hand.
