How Can Diet Improve ADHD Symptoms?
Nutritionist Shares 4 Dietary Principles
25 June 2025

Attention Deficit Hyperactivity Disorder (ADHD) is a common neurodevelopmental disorder affecting approximately 7.5% of children and adolescents, with symptoms including difficulty focusing, hyperactivity, and impulsive behavior. While medication is a common treatment, research shows that dietary adjustments can significantly alleviate ADHD symptoms, boosting brainpower and concentration. Below, a nutritionist shares five dietary principles.
Dietary Principle 1: High-Protein Diet to Stabilize Neurotransmitters
Protein is essential for producing neurotransmitters, which facilitate communication between brain cells, improving focus and stabilizing emotions. Studies indicate that a high-protein diet can reduce impulsive behavior and enhance attention in individuals with ADHD. Opt for lean beef, eggs, fish, beans, nuts, and low-fat dairy, which provide high-quality protein while preventing rapid blood sugar fluctuations that can exacerbate hyperactivity.
Practical Tip: Start the day with eggs and whole-grain toast or enjoy Greek yogurt with nuts as a snack to ensure adequate protein intake.
Dietary Principle 2: Omega-3 Fatty Acids to Boost Brain Function
Omega-3 fatty acids (such as DHA and EPA) are critical for brain function. Research shows that individuals with ADHD often have lower Omega-3 levels in their blood. Supplementing with Omega-3 can improve focus, reduce impulsivity, and enhance neural signaling. A Swedish study found that 25% of ADHD children taking Omega-3 supplements showed significant symptom improvement after three months, with nearly 50% improving after six months.
Practical Tip: Include Omega-3-rich foods like salmon, sardines, or flaxseed oil in your diet. If dietary intake is insufficient, consider high-quality fish oil supplements.

Dietary Principle 3: Low-Sugar and Additive-Free Diet to Minimize Triggers
Processed foods high in sugar and artificial additives (e.g., colorings, preservatives) may worsen ADHD symptoms, particularly hyperactivity and inattention. Studies suggest that a low-sugar, additive-free diet helps stabilize blood sugar, reducing mood swings and impulsivity.
Practical Tip: Avoid sugary drinks, desserts, and processed snacks. Opt for fresh fruit as a sweet alternative and check food labels to choose products without artificial additives.
Dietary Principle 4: Zinc and Magnesium to Regulate Dopamine
Zinc and magnesium are vital for regulating dopamine, a neurotransmitter linked to attention. ADHD individuals often have deficiencies in these minerals, and supplementation can improve focus and behavioral control. Zinc-rich foods include pumpkin seeds, oysters, and lean meats, while magnesium is found in spinach, almonds, and whole grains.
Practical Tip: Incorporate a spinach salad or pumpkin seeds into dinner to ensure balanced intake of these essential minerals.
