In the spring of 2026, I stood before the Interagency Autism Coordinating Committee — the federal body charged with guiding national autism research and policy — and told them about my son Theo.
Theo is nonspeaking. He was not eating. His body was in a state of war with itself. And the clinical system had very little to offer us.
What we discovered — through relentless research, an extraordinary community of parents and practitioners, and our own willingness to try what others dismissed — is what we now call The Theo Protocol. This is the framework I presented to the IACC as a public comment, and I am sharing it here because thousands of families are walking the same road and deserve to know what we've learned.
Pillar One: Nutrition and the Gut-Brain Axis
Whole-food, organic nutrition is foundational to neurological function. For children on the spectrum, however, food restriction and sensory-based food refusal are common and significant barriers. Theo would not allow food near him. His system appeared to be rejecting the very nutrients that could support his development.
The intervention that transformed this was Fecal Microbiota Transplant (FMT). We followed the research of Dr. James Adams at Arizona State University — an autism researcher and autism father whose work in this area has produced some of the most promising outcomes data in the field. Following FMT, Theo's dietary pallet expanded dramatically. He now eats a wide variety of foods.
The clinical implication is significant: the microbiome appears to govern cravings and food acceptance in ways that behavioral intervention alone cannot address. If your child is a severely restricted eater, this is not simply a behavioral problem. It may be a gut problem and the gut can be treated.
We also want to acknowledge Dr. Andrea Macbeth and the research being developed at Thaena Biotic in the Pacific Northwest. This is the kind of translational gut-brain research that deserves federal attention and funding, and we are watching their work closely.
What this means for your family: If your child has extreme food restriction, investigating gut health including microbiome testing and exploring the research on FMT in autism may be the most important step you haven't taken yet.
Pillar Two: Addressing Neuroinflammation
Even after successful gut intervention, Theo's autoimmune neuroinflammation persisted. This is consistent with what many families in our community experience: autism is rarely a single condition. It commonly presents alongside comorbidities and coinfections; PANDAS, PANS, immune dysregulation, mitochondrial dysfunction — that standard clinical protocols do not adequately address.
Our family has pursued a series of stem cell and exosome treatments which have shown genuine promise in Theo's development. However, access to these treatments is severely limited. Cost is extraordinary. Most families cannot access them without traveling outside of the United States. This is not an acceptable state of affairs for a condition affecting 1 in 36 American children.
We shared this reality directly with the IACC: families are already pursuing these interventions, often without clinical guidance, because the research has not kept pace with lived experience. The medical system's silence does not make these interventions go away it just makes them more dangerous and less accessible.
What this means for your family: If your child has immune dysfunction, inflammatory markers, or a history of infections that preceded regression, these are worth investigating. Connect with a functional medicine or integrative physician who understands pediatric neuroinflammation.
Pillar Three: Communication — Every Mind Deserves a Voice
My son is nonspeaking. He has a mind, thoughts, and things to say. The current clinical standards that govern which communication methods receive insurance recognition and school-based reimbursement are leaving nonspeaking individuals without access to their own voice.
Spelling to Communicate (S2C) has produced transformative outcomes for nonspeaking autistic individuals and their families. It is not yet widely recognized in IEP frameworks or reimbursed through insurance and that is a policy failure, not a scientific one.
I asked the IACC to fund rigorous research into S2C, to advocate for its recognition within communication science standards, and to support its inclusion in Individualized Education Programs as a valid, fundable communication method. Nonspeaking does not mean non-thinking. It is time the system caught up to what these children are showing us.
What this means for your family: If your child is nonspeaking or minimally speaking, explore Spelling to Communicate. Find a trained practitioner. Do not let the absence of insurance coverage be the final word.
What We Asked the Federal Government to Do
Our public comment to the IACC included three formal policy requests:
Request One: Prioritize federal funding for microbiome and gut-brain research in autism. Dr. Adams' work at Arizona State University has demonstrated measurable behavioral improvements following FMT in autistic children. This is peer-reviewed science that deserves serious federal investment.
Request Two: Create a domestic research and access pathway for stem cell and exosome therapies. We are not asking the IACC to endorse unproven treatments. We are asking for a regulatory research pathway combined with a compassionate use or research access pathway through the FDA that allows families to access these therapies safely and with clinical oversight, without being forced to travel abroad.
Request Three: Recognize Spelling to Communicate as a legitimate communication method. Fund the research. Advocate for its inclusion in IEP frameworks. Restore access to voice for the nonspeaking individuals who deserve it.
What We Know Now That We Wish We'd Known Earlier
Theo has progressed in ways we were told were not possible. He eats. He communicates. He is present in ways that once seemed out of reach. That progress came from a community of parents, researchers, and practitioners in functional medicine who refused to accept the limits they were given.
The Theo Protocol is not a cure. It is a framework built from lived experience, emerging science, and the stubborn belief that our children are worth the effort of figuring it out. Every pillar of this protocol came from a parent who asked a question the system wasn't asking, or a researcher who refused to accept "we don't know" as a final answer.
If you are a parent newly navigating an autism diagnosis, or you've been in this world for years and feel like you've hit a wall, we want you to know: there is more to explore. The research is moving. The community is strong. You are not alone.
The Pure Living Family Foundation exists to be a long-term partner to families walking this road. We are committed to sharing what we learn in committee rooms, in research conversations, and right here on this blog.
If this post resonated with you, share it with another autism parent. The information families need most is often the hardest to find.
