There are theories that different types of nutritional or dietary interventions, where specific food items are excluded from the diet or where nutritional supplements are added, may affect the symptoms of persons with Attention Deficit Hyperactivity Disorder (ADHD) or autism spectrum disorder. This applies, for example, to gluten-free and casein-free diet, ketogenic diet (a strict option of a low carbohydrate diet) or diet where sugar or various additives are excluded. Nutritional supplements may include fatty acids and vitamins.
Which systematic reviews investigates the effect of nutritional or dietary interventions for children and adolescents with autism spectrum disorder or ADHD?
Studies were identified by a literature search of four electronic databases. The full search strategies are available below. We have only included systematic reviews written in English or Swedish. Thesis’s, guidelines and umbrella reviews have been excluded. A total of 1 472 abstracts were reviewed, and of these, 163 articles were assessed in full. Abstracts as well as full text articles were assessed by one person. 33 systematic reviews were found relevant in relation to the question and are listed below.
