Dietary Interventions

Gluten free diets, casein free diets, elimination diets, supplements, or any combination thereof. Are they any good for people on the autism spectrum? Research still says, no doesn’t really look like it.

Over a decade ago when my children were first diagnosed with autism gluten free and casein free diets were the thing to do to treat autism. I did some digging to find the scientific basis for the belief in this special diet. What I found were studies with small sample sizes, no control groups or poorly matched control groups, no blinded or doubled trials (researchers and participants often knew what they were getting), subjective measurements of outcomes, and no clear mechanism for how the diet was supposed to work or what is was supposed to improve.

I tried a gluten free diet anyway because, hey it was only food. After a year my children were still their autistic selves. I left behind the expensive food and dubious claims about special diets.

The results are still underwhelming.
