Eating Patterns and Dietary Interventions in ADHD: A Narrative Review

Area of Science:

• Neurodevelopmental Disorders
• Pediatric Health
• Nutritional Psychiatry

Background:

• Attention Deficit Hyperactivity Disorder (ADHD) is a prevalent neurodevelopmental disorder in children, associated with significant health and societal costs.
• Pharmacotherapy is a primary treatment, but alternative and complementary approaches are being investigated due to adverse outcomes and costs.
• Emerging research suggests a link between dietary patterns and ADHD risk, prompting exploration of dietary interventions.

Purpose of the Study:

• To review dietary patterns associated with ADHD.
• To summarize evidence on the clinical efficacy of dietary interventions as coadjuvant ADHD treatments.
• To identify specific nutritional strategies for ADHD management.

Main Methods:

• Systematic literature review of case-control studies and intervention trials.
• Analysis of associations between dietary patterns (healthy vs. non-healthy) and ADHD.
• Evaluation of evidence for nutritional supplements, probiotics, and elimination diets in ADHD.

Main Results:

• Non-healthy dietary patterns are positively associated with ADHD, while healthy patterns show a negative association.
• Vitamin D supplementation, particularly with magnesium, may improve ADHD symptoms in cases of deficiency.
• Evidence supports specific probiotics (e.g., Lactobacillus rhamnosus GG) and multi-species probiotics for ADHD.
• Elimination diets show limited evidence and carry risks of nutritional deficiencies.

Conclusions:

• Dietary interventions show potential as complementary treatments for ADHD.
• Specific nutritional supplements and probiotics may offer benefits under certain conditions.
• Further rigorous research is necessary to establish the role of dietary interventions in comprehensive ADHD therapy.
