73% of 26 children with ADHD responded favorably to a diet eliminating reactive foods and artificial colors. 16 of the improved children were given a double blind challenge with 100 mg of mixed food dyes or a food chosen by the parent. ALL of them reacted to the challenge. Placebo effect was ruled out.
