Send us Fan Mail If you have ever been told your child's autism, ADHD, or picky eating is just genetic, just behavioral, or just how they are, this episode is going to change how you see everything. I sat down with Greer McGuinness, registered dietician, functional medicine practitioner, and founder of Biomedical Healing for Kids. Greer has spent years helping families look beyond surface level symptoms and understand what is actually happening inside their child's body. And she knows this world not just as a clinician, but as a mom whose son regressed into autism at 19 months. We talked about the wild west of social media health advice and how to spot who is actually qualified to help your child. We talked about why autism is no longer accurately described as just a genetic diagnosis. We talked about Miralax, GI mapping, gluten, heavy metals, ARFID, and what it actually looks like to work on a child from the inside out. This conversation is honest, direct, and packed with things nobody else is saying out loud. You are going to want to take notes. What You'll Learn in This Episode Why Greer's son regressed into autism at 19 months and what happened when she stopped following conventional adviceHow to spot unqualified practitioners online who are selling one-size-fits-all programs to desperate parentsWhy autism is now understood as a medical diagnosis, not purely a genetic one, and what that means for your childHow heavy metals, oxidative stress, and gut dysfunction show up differently in kids with autism and ADHDWhy Miralax is not the answer to constipation and what to look for insteadWhat the GI MAP test shows that other stool tests miss, and why that mattersWhether gluten free and casein free diets are necessary for every child on the spectrumHow Greer's son went from a VB MAPS score of 56 to a 6 in less than a year using biomedical interventionsWhat ARFID actually looks like in a child whose sensory system is off, and how taste perception can be completely distortedWhy nutrition is the most overlooked piece of the whole child puzzleKey Takeaways 1. Autism is a medical diagnosis, not just a genetic one. The rates of autism are rising too fast and too unevenly across geography and demographics to be explained by genetics alone. Research has found higher levels of heavy metals, lower glutathione, and significant biochemical differences in kids with autism. Treating the body matters. 2. Constipation is a signal, not a condition to manage. There is no such thing as a Miralax deficiency. When a child is constipated, something is happening on the inside. Stool testing, dietary changes, and gut support get to the root. Miralax just keeps the drain open while the clog stays in place. 3. Taste and sensory perception can be genuinely distorted. A child who says food tastes wrong, or who cannot explain why they refuse something, may not be exaggerating. Their sensory system may be giving them completely inaccurate information. This is a body issue, not a willpower issue. 4. Labs are not all created equal. The GI MAP shows both the bad and the good in the gut. Many tests only show pathogens, which means you can kill beneficial bacteria without ever knowing it was low to begin with. Who you test with and what you test for matters enormously. 5. Vet your practitioners. Google their name. Ask in Facebook groups. Check their actual credentials. Anyone can call themselves a practitioner. A licensed professional went through regulated education, sat for board exams, and has their reputation on the line with every recommendation they make. 6. One thing at a time. For overwhelmed families, trying to change everything at once causes shutdown. Greer starts with the highest impact basics: filtered water, cleaner food, supplements. Then layers from there.

There is often a deeper story underneath the behaviors, and you do not have to figure it out alone.
