Could a diet tweak ease autism symptoms? a trial puts three diets to the test
NCT ID NCT07797725
First seen Sep 01, 2026 · Last updated Sep 02, 2026 · Updated 1 time
Summary
This trial tests whether adding a special diet to standard care helps children aged 3 to 8 with autism spectrum disorder. Researchers compare three diets: a low glycemic index diet, a modified Atkins diet, and a gluten-free casein-free diet. The goal is to see if any diet reduces autism severity, measured by a standard scoring tool, after six months. Children continue their usual behavioral, speech, and occupational therapy throughout the study.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Three dietary interventions: low glycemic index diet, modified Atkins diet, and gluten-free casein-free diet, each added to standard care
- What this could lead to
- If one diet works better, it could offer a practical, less restrictive dietary option to ease core autism symptoms in children.
- What could go wrong
- The trial is early and relatively small, and dietary changes can be hard to maintain. Results may not apply to all children with autism.
