Research shows that people with ASD have an abnormal immune response to the protein in soy (as well as the proteins in gluten and casein).
Diet research showed that 91% of ASD children improved on an GFCFSF diet (Gluten-free / Casein-free / Soy-free).
There is also new research showing a link between seizures and soy:
“Excess soy consumption has long been associated with ADD/ADHD, depression, anxiety, dementia and other mental health issues. Now it appears it can aggravate seizures as well. Cara J. Westmark, PhD, and her team at the Waisman Center for Developmental Disabilities at the University of Wisconsin, Madison, pull no punches when they title an article in the Journal of Alzheimer’s Disease “Soy Exacerbates Seizures in Mouse Models of Neurological Disease” and warn, “These results have important implications for individuals on soy-based diets.””
“Infants on soy formula—currently about 25 percent of bottled fed babies according to the American Academy of Pediatrics—are on soy-based diets because they rarely receive anything else to eat, a fact that has led the Israeli Health Ministry, French Food Agency, German Institute of Risk Assessment and British Dietetic Association to warn parents and pediatricians that soy formula could jeopardize brain and body development and should be used only as a last resort.”
