Did you know that April 2 is World Autism Awareness Day? And the entire month of April is now dedicated to Autism Acceptance. There’s a reason for this growing attention. According to the Center for Disease Control (CDC), the percentage of children identified with an autism spectrum disorder (ASD) nearly tripled between 2000 and 2016, to 1 in 54 children (1.9% of all children). And according to their 2021 report, that number has continued to rise. It’s now estimated that 1 in 44 children (2.3% of all children) have been identified with ASD.
Despite the dramatic rise, treatments for heavily symptomatic cases of ASD are limited. Consequently, many families end up trialing therapies, like special diets. The most popular one is the gluten-free casein-free diet.
Does the Gluten-Free Casein-Free Diet Work for ASD?
Scientists are perplexed by this topic. Just a few clinical studies have been done on autism and diet, yielding a mixed bag of results. But they can’t seem to ignore the reality that many people are seeing real world results with dietary changes, like cutting out gluten and casein, the primary protein in milk.
Researchers have suggested a scientific correlation in which peptides from gluten and casein may cause excessive opioid activity that results in many of the physiological and psychological symptoms associated with autism. Other autism nutrition experts, like Julie Matthews of Nourishing Hope, believe this is exacerbated by digestive difficulties in people with ASD.
To back this up, the Autism Research Institute led a study in which over 23,000 parents of autism reported on the success of various treatments. A resounding 65% of participants saw notable symptom improvement with the gluten-free casein-free diet, with only 2% reporting worsening symptoms. On the contrary, of the more than 50 medical drugs tested, only 30% saw symptom improvement, while 31% actually had their symptoms worsen on the drugs.
Researchers later followed up on this study with a more detailed look at studies done on various autism therapies. Again, a resounding 69% of parents said their children improved on the gluten-free casein-free diet, while only 3% saw a worsening of symptoms.
Personal Experiences
Sometimes, a testimonial speaks volumes. Here is one sent to us by a reader, who has chosen to remain anonymous.
When my son was diagnosed with Autism, his peds doc gave me no hope. I started my own research and found a DANs! Doctor. The FIRST thing she had me do was change his diet to GF/CF. I really didn’t think it would do that much, but boy was I wrong! He went from maybe one bowel movement a month (no kidding) to now about 4 a week! He is so happy now!
Diets are Not One Size Fits All
As noted above, not all autism cases benefit from a gluten-free casein-free diet. And some people find benefit in other dietary elimination, like sugar, specific food triggers, and/or food additives. It’s essential to consult with your physician before undergoing any change in diet. They might refer you to a dietitian, who can help ensure a diet with proper nutrients is established. If you do pursue a gluten-free casein-free diet, we have some family-friendly food and recipe ideas to help get you started.

Hi! I want to start my son on a gluten free and casein free diet. But I don t know what to give him as his a very picky eater. Whatever he likes contains gluten and casein.
Our focus is dairy-free, so we can help with that. This site has over 7000 pages of content for dairy-free living, so I created a starter page -> https://www.godairyfree.org/dairy-free-information/new-to-the-dairy-free-diet-start-here
Pingback: Dairy-Free Benefits: The Top 10 Reasons People Go Dairy Free
As a mom with a child touched by autism, thank you for posting this. GFCF diet has help us. It has been a big part of the healing of our son’s gut. I am a believer! I don’t think people understand that we are not celiac but eat this way for other reasons. Hopefully in years to come when more of his symptoms subside and his gut is bullet proof, our son will be able to have a drop of gluten or a drop of dairy without experiencing any side effects. For now we will stay the course of no gluten and no dairy.
