A number of dietary interventions for ADHD have been studied, including the elimination of artificial food colorings, diets high in polyunsaturated fatty acids (PUFAs), and the few-foods diet (a type of elimination diet that gradually reintroduces foods based on how a person’s symptoms change).[1] High-PUFA diets aren’t likely to improve ADHD symptoms, but the few-foods diet is promising. More research on dietary artificial food coloring intake is necessary before it can be recommended for treating ADHD.
