It's great you're looking into the gut-brain connection in autism! Recent research emphasizes how important gut health is for those with ASD. Studies show that children with autism often have imbalances in their gut microbiota, which can affect brain function and behavior.

These imbalances can lead to GI issues like constipation or diarrhea, and may worsen repetitive behaviors, social difficulties, and anxiety. A balanced diet rich in fiber and nutrients is key. It may be helpful to track how GI discomfort affects mood and social skills.

For more in-depth information, Autism.org has some great resources, including articles on diet interventions and a webinar by Dr. Kara Gross Margolis.
