Title : Beneficial effect of Dietary changes and Nutritional supplements on Symptoms of ADHD


Highly processed foods and deficits in nutrients are associated with poor mental health outcomes. This recent study examined the effect of a six-month diet that eliminated gluten, dairy (with A1 protein), food colourings, additives and preservatives, and nutrient supplementation (Fish oils, Zinc, Vit C, Vit. D3, Vit. E, Methylated B complex, Magnesium and a Multimineral complex on 32 children diagnosed with ADHD. A DSM5-ADHD symptoms questionnaire, QEEG, a Test of Variables of Attention (T.O.V.A.) and a faecal microbiology examination were administered pre and post treatment. Results indicate that following treatment, children with ADHD had improvements on all variables with large effect size.

Audience Take Away:

  • Participants will learn the specifics of why and how elements of the “Western-Style” diet of processed foods, high in wheat lectins, food colourings, additives and preservatives interfere with the integrity and function of the gastro-intestinal tract and brain function.
  • They will learn how to use Pathology testing. Quantitative EEG (QEEG) and TOVA to determine the effect of nutrient deficiencies on brain Neurophysiology that underpin various presentations of ADHD.
  • They will be able to use the information provided to effectively treat children with ADHD using specific Dietary changes and Nutrient supplementation.
  • This research may prompt academics to include these aspects in courses teaching Nutritional Psychology.
  • This research provides further support for the effectiveness of Nutritional Psychology, as a treatment option for ADHD.
  • This provides a practical and effective solution to the exponential increase in the prevalence of ADHD and addresses possible root environmental causes of the disorder.


Dr. Duff obtained his undergraduate in Psychology at Swinburne University, his postgraduate in Psychology at RMIT University and his PhD in Clinical Neuroscience in 2010 at the Brain Sciences Institute. His psychological practice is supplemented with Quantitative EEG (QEEG), Clinical Nutrition and EEG biofeedback (Neurotherapy). He has analysed thousands of QEEG assessments to aid in the differential diagnosis of children with ADHD, ASD, Anxiety and Learning Difficulties and for adults with Traumatic Brain Injuries, PTSD, and Psychiatric disorders. He supervises postgraduate students from Victoria University who conduct research in Nutritional Psychology at his clinic.
