Attention-deficit hyperactivity disorder, or ADHD, is an increasingly common neurodevelopmental disorder. Most patients with ADHD experience a combination of hyperactivity, limited impulse control, and a short attention span. There are a number of treatment options for ADHD available, including ADHD medication like Quillivant XR, Adderall, or Concerta, as well as behavioral therapy. However, dietary changes can also mitigate some symptoms. Here are the top five superfoods to boost focus and improve concentration for people with ADHD:

1. Brazil nuts and walnuts
Brazil nuts and walnuts are rich in antioxidants, which can have a powerful effect on brain functioning. Notably, studies have actually linked insufficient antioxidant ingestion with certain neurodegenerative diseases, such as Parkinson’s disease. Additionally, the selenium and ellagic acid found in these nuts have been shown to improve concentration and focus. As such, snacking on these nuts can be a quick and easy way to boost brain functionality.

2. Kiwi
Consuming foods with high vitamin C levels can help support brain health. For example, Kiwi fruit has an extremely high vitamin C content—typically around 64 mg per fruit. Kiwi fruit also contains folic acid, which improves brain and cognitive development, especially in children. It is also important for cardiovascular health. While eating kiwi fruit won’t cure or stop the development of ADHD, it can provide complementary support.

3. Eggs
Eggs are among the best foods a person can eat, especially if the person has an ADHD diagnosis. Eggs contain a high amount of choline, a nutrient shown to improve brain health. Once ingested, the body converts this nutrient into a type of neurotransmitter, which can then improve brain function. Eggs have also been linked to better memory and mental function, which can be important for ADHD patients.

4. Salmon
Salmon is high in protein and omega-3 fatty acids, both of which are critical for brain health, development, and function. Omega-3 fatty acids, in particular, help improve the cardiovascular system and allow more oxygen to reach the brain. This, in turn, helps people to retain new information. This is especially important for ADHD patients who have short attention spans or problems with concentration. Omega-3 fatty acids are also found in other fatty fish, like sardines, herring, and bluefin tuna.

5. Flaxseeds
Flaxseeds are also high in omega-3 fatty acids, which can help regulate brain health. In particular, flaxseed is rich in alpha linolenic acid, or ALA. This fatty acid is commonly found in plants, and it is thought to help the body maintain a normal heart rate. This, in turn, can help decrease the risk of cardiovascular disease and improve cognitive function. Sprinkle flax in a salad, over oatmeal, or in a smoothie for a helpful brain boost.

While implementing these foods into a daily routine can easily complement medication, behavioral therapies, and more to help mitigate ADHD symptoms, patients should consult with their doctors before making any significant changes to their diet.
