A team of Danish nutritionists, medical doctors, and psychiatrists have published a review of the scientific literature on ADHD and diet in the Nordic Journal of Psychiatry. They analyzed 52 studies, some investigating avoiding certain food elements, and others looking at adding certain food elements. “Elimination diets and fish oil supplementation seem to be the most promising dietary interventions for a reduction in ADHD symptoms in children,” concluded the researchers. They cautioned that the studies had “shortcomings,” and more thorough investigations are required.
