First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a special diet that removes certain foods (oligoantigenic diet) can reduce core ADHD symptoms in children aged 6 to 16. Fifty children with ADHD were randomly assigned to either a regular healthy diet or the restricted diet for three months. Researchers measured changes in attention, hyperactivity, and behavior using parent questionnaires and computer tests.
