On the Fence About ABA Therapy? How the Gut-Brain Connection Informs Care

On the Fence About ABA Therapy? How the Gut-Brain Connection Informs Care

Clinical Research Series | Published to the BlackRock Science Resource Lab

Why many traditional approaches miss the mark in Silicon Valley

Many parents hesitate about ABA after reading about rigid programs that never consider what a child might be feeling physically. Children can have a hard time communicating pain or discomfort. When GI symptoms may be affecting participation or behavior, good care looks beyond "task avoidance" and brings in the child's medical team.

This clinical article explains the gut-brain axis and why nutrition belongs in a whole-child behavioral assessment. It was written by Troy Burg, M.S., BCBA, whose Bachelor's in Nutrition and Dietetics from the University of Nevada, Reno informs how he considers nutrition in every functional assessment.

What's inside

• Nutrition in ABA. Why behavioral assessment should weigh possible medical contributors alongside environmental ones.

• The gut-brain axis, explained. What research says about the communication between the gut microbiome and the brain. It also covers why GI symptoms in children with autism, reported in 9% to 90% of cases across studies, are worth paying attention to.

• A clear look at GFCF diets. What the opioid-excess hypothesis proposes, what the evidence does and does not show, and why diet decisions belong with your pediatrician or registered dietitian.

• Food-based learning and healthy habits. How food-based activities create chances to practice language and science concepts, plus recent 2026 research on gamified nutrition education.

• Collaborative care. How BlackRock looks at each child individually and coordinates with your child's pediatrician or dietitian when nutrition may be playing a role.

Who it's for

Parents deciding whether ABA is right for their family, especially when GI concerns or selective eating are part of the picture. Also useful for BCBAs, pediatricians, psychologists, dietitians, and school teams who want a collaborative, whole-child view of behavior.
