It's great you're looking into the gut-brain connection in autism! Recent research highlights a strong link between gut health and behavior in autistic individuals. Studies show that imbalances in the gut microbiome and GI issues like constipation, diarrhea, and bloating can worsen behavioral symptoms such as anxiety, irritability, social withdrawal, and repetitive behaviors.

A recent study even found lower levels of important brain metabolites in autistic children, which correlated with altered brain activity and symptom severity. The good news is that dietary changes to increase food variety and including foods rich in tryptophan (like turkey and eggs) can be helpful. Some studies show that addressing gut issues can improve behavior, so it's definitely worth exploring!
