Many children with autism, Asperger's, ADHD, sensory processing disorders, learning disabilities, or mood/behavior issues have nutrition problems stemming from malabsorption, bowel problems, and/or inadequate diet. These impede learning, growth, behavior, and functioning in all children—not just special needs children. Not surprisingly, when you address the nutrition problems of these kids, the symptoms of their disorder lessen and, in some cases, disappear.
