Elimination Diets and Nutrition in Autism
Exploring gluten and casein sensitivities, elimination protocols, and evidence-based dietary interventions in individuals on the autism spectrum.
Gluten-Casein Leaking and Opioid Excess Theory
Some individuals on the autism spectrum have higher intestinal permeability (leaky gut). Gluten and casein proteins can enter the bloodstream partially undigested, crossing the blood-brain barrier and converting into opioid-like compounds (gluteomorphins and casomorphins).
This can trigger brain fog, sensory hypersensitivity, hyperactivity, and social withdrawal.

How to Implement a Safe Elimination Diet
Under a dietitian's supervision, gluten and casein are completely removed from the child's diet for a trial period (typically 4-6 weeks), while recording changes in digestion, sleep, and behaviors.
Unplanned elimination can lead to calcium or fiber deficiencies, so it must be conducted under control with proper alternative foods.
