Well, since ADHD does not exist and was invented from whole cloth entirely to enrich the therapist class, who cares?
My grandson (7) has been diagnosed with ADHD. In lieu of medication my son and dil have decided to pursue whether food preservatives and processed foods are the culprit.
After two weeks on natural foods the ADHD symptoms have abated. Now they are introducing foods one at a time to find what foods are the cause of the ADHD.
