Researchers, however, said that their review of recent controlled scientific studies had shown conflicting evidence on the impact of supplements and restricted diets - in some cases they were no better than the placebo effect.
Nutritional interventions should therefore be considered an alternative or secondary approach to treating ADHD, not a first-line attack, said the review by doctors at Northwestern University Medical School in Chicago.
"Supplemental diet therapy is simple, relatively inexpensive, and more acceptable to patient and parent," than strict additive-free diets that have been popular in the past, said the study.
"Public education regarding a healthy diet pattern and lifestyle to prevent or control ADHD may have greater long-term success."
The study reviewed research published on the sugar-restricted, additive-free Feingold Diet, megavitamin therapies, omega-3 fatty acid supplementation and the suspected link between ADHD and a "Western-style" high-fat, low-fiber diet.
