Dietary studies for autism are also few and far between for the same reasons as outlined above in relation to ADHD. The next best thing is a study involving supplementation – it’s not quite representative of real dietary changes as a change in food would be of course, but at least it can be carried out in a double-blind randomised controlled fashion which eliminates any bias and carries much more weight within the scientific community.
The following is just such a study. It involved giving 141 children and adults with autism, a multi-nutrient formula containing a broad range of vitamins and minerals or a placebo. Their symptoms were assessed before and after the study which ran for three months. Fifty-three of the children in the study also had blood measures taken of nutritional and metabolic status(biomarkers) before and after.
In terms of symptoms, the supplemented group had significantly greater improvements than the placebo group on the following scores: Parental Global Impressions (PGI-R), Hyperactivity, Tantrumming, Overall and Receptive Language. Th change in the PGI-R was strongly associated with a number of the biomarkers suggesting that there is a relationship between changes in biomarkers and changes in symptoms.
Levels of many vitamins, minerals, and biomarkers improved including markers of oxidative stress thought to be elevated in autism, as well as markers of key biological processes such as methylation and sulphation.
