diets are generally not effective -- especially for school-age children or teens. sugar and food coloring are not the cause of adhd nor are food allergies in general. (food coloring can have a small barely measurable effect but this is not the cause of your child's adhd. ) that said there are a few "nutriceuticals" that may improve adhd. studies are limited; the amount of benefit is likely to be less than medication and they may not benefit all kids with adhd.
what can you tell me about adhd diets?
