Abstract:

With reports of the growing incidence of autism spectrum disorder ASD in the United States, a large number of families of affected children is seeking alternative or complementary forms of treatment. One of the more popular interventions has been use of elimination regimes, such as the gluten and casein free (GFCF) diet. This pilot study involved a three-month, prospective, open label, randomized, parallel groups design of a GFCF diet compared to a healthy, low sugar diet (attention control) for young children with ASD. Both treatment groups evidenced some gains across a range of variables, including measures of behavior, language, and ratings of the core features of ASD. No statistically significant differences were noted between treatment groups. While our results do not support use of a GFCF diet in ASD, it is possible that a greater period of time is required for treatment before gains can be observed. Moreover, no significant nutritional differences or side effects were observed on the GFCF diet compared to the control diet. However, adherence to the GFCF diet proved difficult based on our adherence data.
