Diet and nutrition are believed to have a direct impact on ADHD symptoms. While there are no official dietary guidelines for adults with ADHD, a healthy, well-balanced diet with a generous portion of fruits and vegetables, whole grains, healthy fats, and proteins is recommended. This ensures that nutritional needs are met and helps to keep the mind and body in their best state. Research has shown that various nutrients can help improve ADHD symptoms, while a lack of certain nutrients may worsen them. Specific nutrients such as vitamin D, zinc, iron, and polyunsaturated fatty acids have been proposed as coadjuvants in the treatment of ADHD. Additionally, diets high in sugar, unhealthy fats, and simple carbohydrates are generally discouraged for people with ADHD.

What You'll Learn
High-protein diets
A high-protein diet is often recommended for managing ADHD symptoms. Protein-rich foods are used by the body to make neurotransmitters, the chemicals released by brain cells to communicate with each other. Neurotransmitters such as dopamine, serotonin, epinephrine, and norepinephrine are essential for maintaining attention and focus.
Protein sources such as lean beef, pork, poultry, fish, eggs, beans, nuts, soy, and low-fat dairy products can be beneficial for individuals with ADHD. These foods provide the body with the amino acids needed to produce neurotransmitters like dopamine, which is often linked to improved focus and alertness.
In addition to improving focus, a high-protein diet can help stabilise blood sugar levels. This is because proteins are digested and absorbed more slowly than simple carbohydrates, preventing spikes in blood sugar that can negatively impact concentration and energy levels. By including protein in each meal and snack, individuals with ADHD can maintain stable blood sugar levels throughout the day, supporting better focus and energy.
Furthermore, a high-protein diet for ADHD should be paired with other nutritious foods. Complex carbohydrates, such as whole grains, fruits, and vegetables, are recommended as they provide sustained energy release and essential nutrients. Healthy fats, such as those found in avocados, olive oil, and nuts, are also important for brain function and overall health.
While a high-protein diet can be beneficial for managing ADHD symptoms, it is not a cure. Medication and behavioural therapy remain the most effective treatments. However, a well-balanced diet that includes adequate protein can support overall brain function and help optimise the management of ADHD symptoms.

Complex carbohydrates
While there is no one-size-fits-all approach to managing ADHD, and dietary recommendations are not a substitute for medical advice, some experts believe that diet and nutrition can directly impact ADHD symptoms. Complex carbohydrates are an important part of a well-balanced ADHD diet, as they can help manage blood sugar levels and improve focus and attention.
There are many food sources of complex carbohydrates. These include oatmeal, bran, higher-fibre cereals and pastas, legumes (such as soybeans, kidney beans, and lentils), and dairy products like milk and plain yogurt. Fruits and vegetables are also good sources of complex carbohydrates, although they contain simple carbohydrates as well. Oranges, tangerines, grapefruits, apples, kiwis, and pears are recommended by some sources.
When incorporating complex carbohydrates into your diet, it is important to be mindful of the type and amount you consume, as well as the time of day. While complex carbohydrates can help stabilise blood sugar levels, all carbohydrates, including complex ones, will raise blood sugar to some extent. Therefore, it is recommended to eat these foods in the evening, as they may also help with sleep.

Omega-3 fatty acids
Several studies have found that omega-3 fatty acids can have beneficial effects on ADHD symptoms, including improvements in hyperactivity, impulsivity, attention, visual learning, word reading, and working/short-term memory. One study of 180 children with ADHD and 180 without the disorder found that the ADHD children had a 60 to 70 percent greater likelihood of a variation in a gene necessary to metabolize fatty acids. Another study of 95 children diagnosed with ADHD found that supplementing with omega-3s improved "working memory" — the short-term recall that is key to learning. A systematic review of 16 randomised controlled trials involving 1,514 children and young people with ADHD found that 13 of the trials reported favourable benefits on ADHD symptoms.
Israeli researchers studied 78 ADHD children (ages nine to 12) with sleep problems, giving them either an omega-3/omega-6 supplement or a placebo. After 10 weeks, the children taking the supplement slept better, were less fatigued during the day, and were better able to cooperate with others.
The American Psychiatric Association recommends that people with “impulse control disorders,” like ADHD, supplement their daily diets with at least 1 gram of fish oil. Fatty fish and fish oil supply two of the most important essential fatty acids for your brain: EPA, or eicosapentaenoic acid; and DHA, or docosahexaenoic acid. Good sources of omega-3 fatty acids include tuna, salmon, and other cold-water white fish. Walnuts, Brazil nuts, and olive and canola oils are other foods with omega-3 fatty acids.

Nutritional supplements
Supplements may be especially useful for those with ADHD as they ensure the daily recommended intake of certain nutrients is met. This is particularly relevant when dietary restrictions, food allergies, or lifestyle choices limit the intake of certain nutrients.
Some of the most studied supplements for ADHD include:
- Omega-3 fatty acids: Found in fish oil, omega-3 fatty acids have shown promising results in improving attention and reducing hyperactivity and impulsivity.
- Iron: Iron is essential for neurotransmitter production, especially dopamine. Iron supplementation has been linked to improvements in ADHD symptoms, particularly in those with diagnosed deficiencies.
- Zinc: Zinc is important for dopamine regulation and has been observed to potentially enhance the effectiveness of ADHD medication, reducing the required dosage and addressing symptoms like impulsivity and hyperactivity.
- Magnesium: Magnesium is used to make neurotransmitters involved in attention and concentration, and it has a calming effect on the brain. Research has shown that adding magnesium supplements may decrease some ADHD symptoms and aid in relaxation.
- Melatonin: Melatonin is a hormone that helps regulate sleep. It has been used to treat chronic insomnia in children with ADHD, but it does not appear to reduce core ADHD symptoms.
- Polyunsaturated fatty acids: There is some evidence that polyunsaturated fatty acid formulations with higher eicosapentaenoic acid may be effective in improving ADHD symptoms.
It is important to remember that individuals may respond differently to the same nutritional intake, so consulting with a registered nutritionist or dietician is essential to determine specific dietary needs. Additionally, taking more than the recommended levels of certain nutrients can be harmful to one's health.

Elimination diets
An elimination diet involves removing common trigger foods to identify food sensitivities that may worsen ADHD symptoms. Elimination diets are based on the hypothesis that ADHD involves food hypersensitivity or intolerance. This type of food intolerance is often considered a toxicologic or pharmacologic response to chemicals found in food.
There are three main types of elimination diets: the "oligoantigenic" or "few foods" diet, the multiple food diet, and the single food diet. The oligoantigenic diet is most often used in research studies as it consists of a very small number of foods and is difficult for individuals to maintain on their own. In this diet, an individual removes one or more foods from their diet for a period of time to identify food sensitivities.
A 2011 study published in The Lancet found that children with ADHD who followed a strict oligoantigenic elimination diet saw a 64% improvement in their symptoms after five weeks, while children who ate a normal "healthy" diet saw no change. However, some experts have criticised this research as not being sufficiently blinded. Other double-blind studies, most published in the late 1970s and early 1980s, concluded that as many as 30% of children with ADHD responded positively to elimination diets.
A 2025 study examined the short-term effects of an elimination diet (ED) and a healthy diet (HD) in children with ADHD. Fewer ED (34.5%) than HD (50.6%) participants showed improvement in ADHD symptoms. Predictors for long-term benefit from dietary treatments included the high initial severity of ADHD problems, low severity of emotional problems, and sufficient parental mental resources.
The TRACE study, published in 2020, was the first to examine the long-term effects (one year) of offering an ED and HD as initial treatment for ADHD. The study included a randomized controlled trial with children aged 5-12 years with ADHD who were randomized to either ED or HD. A non-randomized comparator arm was included with children being treated as usual (CAU). In the ED, foods that may trigger ADHD problems were eliminated, such as food allergens like cow's milk or wheat.
