There is limited evidence that dietary changes might affect schizophrenia. The Dietary Inflammatory Index (DII) is a metric used to assess the inflammatory potential of a dietary pattern. A higher DII score is associated with a more inflammatory diet. A small observational study found that people with schizophrenia are more likely to follow a dietary pattern with a high DII score.[1] Some trials also found that a gluten-free diet reduced symptoms of schizophrenia. However, additional trials failed to find the same result.[2]
