Recent research shows a strong gut-brain connection in autism, where imbalances in gut bacteria (like lower microbial diversity) can influence behaviors, brain function, and GI symptoms. Studies found that autistic children often have altered gut metabolites linked to social difficulties and repetitive behaviors. For example, a 2023 USC study tied lower levels of neuroactive compounds like kynurenine to symptom severity. Prenatal immune responses may also play a role, affecting both brain development and gut health.

Practical steps: Focus on gut-friendly diets (tryptophan-rich foods), probiotics like *L. reuteri*, and monitor for leaky gut or yeast overgrowth. Improving gut health may ease some autism-related behaviors. Learn more at TACA's resources: https://tacanow.org/family-res....ources/the-gut-brain
