I know about that. My aunt is Chinese (from Thailand) and she cooks awesome food. I know a lot of behavioral/mental disorders are from kids being fed processed crap, but I do not think it's the case with my aunt. I read the book "The Unhealthy Truth" and the woman who wrote the book talked about how a milk allergy was causing her son's autism. I think they need to take their son to a naturopathic doctor to find the root cause rather than addressing the symptoms.
