Despite the plethora of anecdotal success stories of alternative diets for autism, scientific research is unable to support many of the claims we hear. That doesn’t mean diets like gluten-free and casein-free won’t help your child’s symptoms. What it does mean is that there is no guarantee these diets help. Every child has a different response to food just as every child’s autism experience is different.
Because of the uncertainty associated with special elimination diets for autism, I suggest looking to easier diet modifications to first.
