Dietary Approaches for ADHD: Evidence-Based Nutrition Strategies

No single "ADHD diet" exists, but targeted nutritional interventions may support symptom management:

1. Elimination/Reduction of Triggers

• Artificial colors (Red 40, Yellow 5), preservatives (sodium benzoate) – some RCT support
• Test for food sensitivities (IgG not validated); consider oligoantigenic diet under supervision

2. Omega-3 Fatty Acids (DHA/EPA)

• Meta-analyses show modest benefit for inattention/hyperactivity
• Sources: fatty fish (2×/wk), algal oil, flax/chia/walnuts

3. Limit Added Sugars & Ultra-Processed Foods

• Blood glucose swings exacerbate dysregulation
• Whole foods, complex carbs, regular meals

4. Adequate Protein & Key Micronutrients

• Tyrosine/phenylalanine → dopamine/norepinephrine precursors
• Screen/treat: iron, zinc, magnesium, vitamin D, B6, B12

5. Gut-Brain Axis Support

• Probiotics, fermented foods, prebiotic fiber

6. Hydration & Caffeine Moderation

Individualized approach with registered dietitian and prescribing clinician recommended.
