NOT RECOMMENDED
Gluten-free / casein-free and other exclusion diets for autism
Not recommended for core autism features; medical dietary needs are a separate question.
Not recommended for the use described below. We include it because people ask about it, and the honest answer matters.
How it works
Exclusion diets remove foods such as gluten or dairy, sometimes based on theories about autism that have not held up.
What the evidence says, use by use
Evidence is specific to the condition, population and—for devices—the exact product. One label never covers everything.

Cautions & things to know
- Restrictive diets can cause nutritional deficiencies, especially with selective eating.
Questions for a clinician
Conversation prompts, not a treatment plan.
- Should GI symptoms or selective eating be assessed by a doctor or dietitian?
Educational, not medical advice. NeuroCoach is an educational and care-navigation resource, not a medical provider. Information about medications, supplements, therapies, devices, clinical trials and community experiences is provided for education and exploration and is not a recommendation, diagnosis or treatment plan. Evidence varies substantially among interventions. Decisions about medical or mental-health treatment should be made with an appropriately qualified healthcare professional. Do not start, stop or change medication, supplements or treatment based solely on information found here.
