Arizona State University Study Proves Nutrition and Dietary Intervention Effective at Improving Autism

Contrary to historical medical beliefs and public education and perception, new controlled twelve-month study shows that diet and nutritional intervention significantly improves the symptoms, cognition, digestive health, and behavior in individuals with Autism (ASD).

SAN FRANCISCO--()--Nourishing Hope, a world leading authority on nutrition and dietary intervention for the healing of Autism and other neurodevelopmental disorders, today announced that a recent study by Dr. James Adams, Director of the Autism/Asperger’s Research Program at Arizona State University, co-authored by Julie Matthews of Nourishing Hope, definitively proves that nutrition and dietary intervention do, in fact, significantly reduce the symptoms and behaviors associated with individuals with Autism Spectrum Disorder (ASD).

Dr. Adams’ study, published in a peer-reviewed journal, Comprehensive Nutritional and Dietary Intervention for Autism Spectrum Disorder (download study here), A Randomized, Controlled 12-Month Trial, shows a direct and irrefutable correlation between nutrition and improvements in Autism symptoms. Dr. Adams has published dozens of research papers over 15 years of investigating nutrition and Autism, showing similar outcomes.

“The positive results of this study confirm that a comprehensive nutritional and dietary intervention is proven and effective in improving non-verbal IQ, Autism behaviors, developmental age, and other symptoms in most individuals with ASD,” says Dr. Adams. “For 16 years Nourishing Hope has provided scientifically based nutrition strategies that help children and adults with Autism around the world. Now, their founder Julie Matthews has contributed to this 'gold standard' research study that substantiates their approach.”

The comprehensive nutrition approach significantly improved:

  • Cognitive function, 6.7 point increase in IQ
  • Developmental age increased by 18 months in the treatment group vs. 4 months in the non-treatment group
  • Gastrointestinal symptoms
  • Speech, sociability, irritability, hyperactivity, and more

Matthews adds, “The study also shows that no matter the age of the individual with Autism, diet and nutrition intervention can help. It’s never too late to be nourishing hope!”

The study was a randomized controlled trial. A total of 117 individuals, aged 3 to 58, were enrolled in the study. 67 of the participants had been previously diagnosed with ASD; the remaining 50 participants were neuro-typical. Those with ASD were randomly assigned to a treatment group (37 participants) or a control group (30 participants) after having been physically examined by the study physician.

The study measured the effects of six nutritional interventions introduced over the course of a year, including supplementation and a healthy allergen-free diet.

Each of the interventions had already been studied individually, and demonstrated to be effective at improving Autism symptoms. Researchers anticipated a synergistic effect from this comprehensive approach, and the results were substantial.

1 in 59 children are affected, and $137 Billion is being spent annually to support those with Autism. It’s time for mainstream medicine and media to embrace Nourishing Hope’s proven and effective solutions and help every family living with Autism and related healthcare issues. The process is safe, natural, and provides what the human body requires most: quality food and individualized nutrition.

The organization is hosting a free online educational event titled Nourishing Hope for Autism Summit on July 16 – 20. For more information and to register, visit
