ADHD & Diet: A Look at the Foods That Can Help or Hinder Focus

When we consider treating ADHD, it’s easy to think of medication, therapy, or various forms of behaviour modification. But an important (and often neglected) piece of the equation is what we eat. The food we consume can shape our brain's chemistry and function, and for the ADHD brain, which is so dependent on neurotransmitters such as dopamine and norepinephrine, what we eat can be a powerful tool. It is not a cure and will not replace all other treatments, but by choosing your foods with the brain in mind, you can build a brain that is more stable and more supportive of what you want it to do. This is all about powering your body & mind for sustained focus, energy, and overall wellness.

The Building Blocks: Protein, Complex Carbs + Healthy Fat

Good brain health is rooted in healthful eating. The ADHD brain really thrives on a steady stream of foods that boost energy levels and neurotransmitter production (which are both super crucial for ADHD). Protein is particularly vital. It’s processed into amino acids, which are the precursors for essential neurotransmitters. To help the organ maintain a steady supply, include a source of protein in every meal and snack, such as lean meats, fish, eggs, beans, or nuts.

Complex carbohydrates are also essential. Whereas simple sugars lead to a quick rise and fall of blood sugar, complex carbs (in whole grains, fruits, and vegetables) release glucose more slowly into the bloodstream. That’s a stable, slow-burning fuel source for your brain, so you won’t experience the “hangry” irritability and brain fog resulting from blood sugar ups and downs.

Don't forget about healthy fats (particularly omega-3 fatty acids). These fats are essential for brain function, cell structure, and communication. Read the full info here. Studies have demonstrated that they may support attention, increase focus, decrease hyperactivity, and improve cognitive function. Fluid fish such as salmon, walnuts, flaxseeds, and chia seeds are excellent sources. Adding these fats to your diet can help make your brain more robust and wise.

Foods That Hinder Focus

Some foods and drinks can support your immune system, but some can do the opposite. The two main agitators are simple sugars and processed foods. They spike blood sugar levels very fast — yielding what may feel like an immediate energy boost — but a quick drop follows. This sugar high-low rollercoaster may also worsen symptoms of ADHD, leaving kids even more irritable and restless with even less ability to concentrate. Avoid sugary drinks, candy, pastries, and other sweets, and avoid refined grains such as white bread and white pasta. These foods provide little nourishment and can horribly disrupt your brain chemistry. Likewise, artificial additives and food dyes have been associated in some research with heightened hyperactivity in children. Without clear evidence in adults, your best bet would always be whole, unprocessed foods.

Strategic Snacking and Hydration

Sticking to a routine is critical for controlling ADHD symptoms, and this is also true regarding how you eat. There’s also the risk of blood sugar crashing, making concentrating even more challenging. One way to do that is to have regular meals, with strategically placed nutrient-filled snacks interspersed during the day. “Grab a portion of almonds, an apple with some peanut butter, or a serving of Greek yogurt to help prevent energy from plummeting between meals. Another intangible but commonly overlooked component is hydration. Mild dehydration may also interfere with cognitive function, making you feel tired, restless, or inattentive and otherwise resemble or exacerbate ADHD symptoms. Get into the habit of having a water bottle with you, and drink it throughout the day. It’s a minor adjustment that can make all the difference in staying focused.
