What Is Glutamate? And Why Does It Matter for Kids with Developmental Challenges?

 
 

If your child struggles with autism, speech delays, Childhood Apraxia of Speech (CAS), complex picky eating, sensory processing challenges, PANS/PANDAS, developmental concerns or behavior issues and you’ve started wondering about the role of food in all of it… you’re not alone. One area more and more families are exploring is the impact of glutamate on the brain and nervous system.

Glutamate is a naturally occurring amino acid that also functions as a major excitatory neurotransmitter in the brain. That means it helps nerve cells communicate. While glutamate is essential in proper amounts, too much glutamate can overstimulate the brain, leading to symptoms like poor regulation, speech or language challenges, heightened anxiety, or even aggressive behavior among other symptoms.

And here’s the catch: glutamate is not only created naturally in the body, we also get it from exogenous sources from a wide range of processed and “natural” foods, often under names like “yeast extract,” “hydrolyzed protein,” “citric acid”, or “natural flavors.”

For some sensitive children, reducing glutamate in the diet (often through a version of The Reduced Excitatory Inflammatory Diet (REID) created by Dr. Katie Reid, Ph.D. or other low-glutamate diet approaches) can lead to remarkable improvements in symptoms – from regulation to communication, to behavior, and even feeding challenges.

To explore this more deeply, I hosted a conversation with my friend Andi Stowe of Nourished Blessings, who used the REID Program to support her son’s healing journey. In this interview, she shares:

  • What glutamate is and where it hides in foods

  • Why it can impact neurodevelopment and behavior

  • How her family transitioned to a low-glutamate diet

  • The speech, feeding, and emotional regulation changes they saw

  • Tips for families curious about getting started

Even if you’re just beginning to explore food’s connection to development, this conversation is packed with practical insights and gentle encouragement. If your child is sensitive, stuck, or struggling, and you’re curious about what food might be doing under the surface, I trust you’ll find this conversation helpful.

Here’s to your child and family’s health and wellness,
