Confused about diets for neurodivergent kids? In this episode, we answer Which Therapeutic Diet Helps Neurodivergent Kids, breaking down GFCF, keto, paleo, and more with Julie Matthews—guided by Dr. Roseann Capanna-Hodge’s Regulation First Parenting™ approach to calming emotional dysregulation.
Which therapeutic diet really helps neurodivergent kids? Here’s what you need to know.
Kids with ADHD, autism, anxiety, and emotional dysregulation can struggle so much, and you’re not imagining it—food truly can make or break their mood, focus, and behavior.
In this episode, I talk with nutrition expert Julie Matthews about which therapeutic diet really helps neurodivergent kids, how diet affects the brain, and simple ways to start even if your child is picky.
Why does food affect my child’s mood, behavior, and attention so much?
Food is powerful because it either nourishes the brain or bogs the nervous system down with inflammation. Julie breaks it into two parts:
- Add nutrient-dense foods that support brain function, address nutritional deficiencies, and promote brain health in children with autism and other autistic patients.
A healthy and balanced diet or targeted dietary interventions can make a big difference.
- Remove problematic foods that affect gut health, trigger immune system dysregulation, and impact cognitive function.
Options may include a gluten free diet or ketogenic diets, tailored to genetic and environmental factors.
Even brief swaps from processed foods and high sugar intake to whole foods often improve GI symptoms, autistic symptoms, mood, and attention.
Key takeaways:
- Inflammation = dysregulation
- Nourishing foods calm the brain faster than most parents expect
- Even one small change—like reducing dyes or food additives—can shift behavior fast
Parent Story
One mom shared that removing red dye led to fewer after-school meltdowns within 48 hours—proof that eliminating unhealthy foods and additives can dramatically shift autism severity and mood disorders.
Which therapeutic diet really helps neurodivergent kids?
There’s no one-size-fits-all diet, but Julie’s clinical experience is clear: most neurodivergent children improve when they reduce sugar intake, remove gluten free casein (GFCF) triggers, and focus on healthy foods that improve gut bacteria, immune response, and brain development.
Her book outlines a 12-step plan for implementing therapeutic diets, starting with removing dyes, flavors, preservatives, and then tailoring the diet to a child’s unique nutritional needs, GI disorders, and food sensitivities.
Helpful starting points:
- Avoid artificial colors and additives
- Reduce sugar
- Remove gluten and dairy (high-impact inflammation triggers)
- Add protein, healthy fat, and whole foods
Why this matters: 70% of American kids rely heavily on processed foods—foods that overstimulate the nervous system and deplete nutrients needed for attention and regulation.

How do I start improving nutrition when my child is picky?
You’re not alone—every parent worries about this. Julie reminds us that picky eaters can still make progress because the first steps don’t require major sacrifice.
Instead of taking away everything at once, begin with easy swaps your child will accept.
Try these:
- Swap their usual cookie for a clean ingredient version
- Replace sugary snacks with fruit + nuts (instant mood difference!)
- Start introducing new foods alongside favorites
- Keep flavors simple—kids often prefer it that way
Real-Life Scenario
A child who only ate beige foods tolerated a preservative-free version of their favorite snack—and that small win opened the door for new foods.
What’s the best first step if I feel overwhelmed?
Nutrition doesn’t have to be complicated, and you don’t have to overhaul everything today.
Start with ONE of these:
- Remove artificial dyes
- Add protein at breakfast
- Swap processed snacks for cleaner alternatives
- Remove gluten or dairy for 2 weeks
- Add healthy fats to stabilize mood
When kids feel better—less anxiety, fewer headaches, calmer afternoons—they’re naturally more open to continuing the diet.
🗣️ “Once kids feel dramatically better, it becomes easy to follow the diet because the brain and body start working the way they should.” — Dr. Roseann.
Quick CALM helps your child’s nervous system stay regulated while you slowly shift nutrition, so diet changes feel easier and meltdowns decrease.
Takeaway & What’s Next
Nutrition has a powerful, often immediate impact on mood, behavior, and regulation. When you calm inflammation and feed the brain well, kids feel better—and that means fewer meltdowns, clearer focus, and more calm in your home.

FAQs
How fast can diet changes help neurodivergent kids?
Some families see shifts in days, especially when removing dyes, gluten, dairy, or sugar.
Are artificial dyes really linked to hyperactivity?
Yes—research going back to 2007 shows additives can increase hyperactivity in all kids, not just neurodivergent ones.
Is gluten-free always necessary?
Not always—but it’s one of the most impactful first steps for inflammation and behavior.
Which diet works best for ADHD or autism?
A personalized approach works best, but most kids benefit from removing irritants and adding whole, nutrient-rich foods.
