There is no definitive scientific evidence that ADHD is caused by nutritional deficiencies or food intolerances. However, some studies have shown that certain foods may play a role in affecting symptoms in a small group of people. For example, a Korean study found that a high intake of sweetened desserts, fried foods, and salt was positively associated with learning, attention, and behavioral problems. In contrast, a balanced diet with regular meals and a high intake of dairy products and vegetables was negatively associated with these problems. Additionally, some research has found that omega-3 fatty acid supplements have positive effects on ADHD symptoms, with one study showing lower impulsiveness scores in children after adding more omega-3s to their diet for 8 weeks. While there is no one-size-fits-all approach to ADHD diets, some general recommendations include incorporating more protein-rich foods, complex carbohydrates, and omega-3 fatty acids, while limiting simple carbohydrates, sugary foods, and artificial additives. The duration of time it takes for these dietary changes to have a noticeable impact on behavior may vary depending on the individual, the severity of their symptoms, and the consistency of their diet.

What You'll Learn
The role of omega-3 fatty acids and vitamin D supplements
While there is no clear scientific evidence that Attention Deficit Hyperactivity Disorder (ADHD) is caused by diet or nutritional problems, certain foods may play a role in affecting symptoms in a small group of people. Research in this area is ongoing, and results are mixed. However, experts say that whatever is good for the brain is likely to be good for ADHD.
Omega-3 fatty acids and vitamin D supplements have been found to have positive effects on ADHD symptoms. Omega-3 fatty acids are essential for brain health, and a deficiency has been linked to disorderly brain activity in ADHD patients. Studies have shown that supplementing with omega-3s consistently reduces hyperactivity and improves attention in children with ADHD. The American Psychiatric Association recommends that people with ADHD supplement their diets with at least 1 gram of fish oil, which is a source of omega-3 fatty acids. However, it is important to note that high doses of omega-3 supplements (more than 4 grams per day) can create an imbalance in essential fatty acids.
Vitamin D supplementation has also been found to have a small but statistically significant improvement in ADHD total scores, inattention, hyperactivity, and behavior scores. A review of multiple studies found that a group of children diagnosed with ADHD had lower levels of vitamin D than a group without ADHD. Additionally, in one study, children who were given a vitamin D supplement along with prescription medication showed improvement in hyperactivity, inattention, and behavior scores.
It is important to remember that dietary changes should not replace prescribed medical treatment for ADHD. While diet and nutrition may play a role in managing symptoms, medication and behavior therapy are currently the most recommended forms of treatment.

The effects of eliminating preservatives, artificial colours, MSG, and sugar
While there is limited research on the impact of diet on ADHD symptoms, some studies suggest that certain foods may affect symptoms in a small group of people. The effects of eliminating preservatives, artificial colours, MSG, and sugar from the diet of someone with ADHD are discussed below.
Preservatives
The American Academy of Pediatrics agrees that cutting out preservatives is a reasonable option for children with ADHD. Eliminating preservatives is considered an "alternative" treatment for attention deficit disorder. While there is some support for this approach, it is viewed with suspicion by many medical practitioners.
Artificial Colours
Artificial colours have been linked to adverse neurobehavioral outcomes in some children. A report by the California Environmental Protection Agency found that synthetic food dyes are associated with negative neurobehavioral outcomes in some children. Comparisons with newer studies indicate that current Acceptable Daily Intake (ADI) levels for synthetic food dyes may not adequately protect children from behavioural effects. However, the European Food Safety Authority (EFSA) has rejected suggestions of a link between hyperactivity in children and mixtures of food colours.
MSG
MSG is a flavour enhancer that is naturally found in a range of food sources, including seaweed, soy sauce, and tomatoes. The Feingold Diet, which eliminates MSG, has been found to have no favourable effect when tested scientifically. Most reputable studies have failed to establish a link between MSG and hyperactivity.
Sugar
Some studies have found no correlation between refined sugar and increased hyperactivity in children with ADHD. However, other studies suggest that sugar may worsen symptoms of ADHD and increase inattention. A study by the University of South Carolina concluded that higher sugar consumption led to more destructive and restless behaviour in hyperactive children.
It is important to note that the impact of dietary changes on ADHD symptoms may vary depending on individual factors, and more research is needed to fully understand the relationship between diet and ADHD.

The importance of protein-rich foods and complex carbohydrates
While there is no clear scientific evidence that Attention Deficit Hyperactivity Disorder (ADHD) is caused by diet or nutritional problems, certain foods may play a role in affecting symptoms in a small group of people. Research in this area is ongoing, and results are mixed. However, experts agree that eating nutritious meals helps the brain function, and a well-rounded diet is essential for overall good health.
Protein-rich foods are an important part of a nutritious diet for people with ADHD. Protein triggers alertness-inducing neurotransmitters, which can improve concentration and cognitive function. Good sources of protein include beans, cheese, eggs, meat, and nuts. These foods can be eaten in the morning or as snacks throughout the day to enhance focus and possibly make ADHD medications more effective.
Complex carbohydrates are another essential component of a healthy diet for people with ADHD. Carbohydrates are converted into glucose, which the body uses for energy. Unlike simple carbohydrates, complex carbohydrates are slowly absorbed by the body, providing a steady release of energy without spiking blood sugar levels. Examples of complex carbohydrates include oatmeal, bran, high-fiber cereals, and legumes such as soybeans, kidney beans, and lentils.
In addition to protein-rich foods and complex carbohydrates, a balanced diet for ADHD should also include healthy fats, vitamins, minerals, and omega-3 fatty acids. These nutrients support overall health and brain function, potentially improving ADHD symptoms. It is important to note that dietary changes should complement prescribed medical treatments for ADHD and not replace them.

The impact of dietary deficiencies on ADHD symptoms
While there is no clear scientific evidence that Attention Deficit Hyperactivity Disorder (ADHD) is caused by diet or nutritional problems, research suggests that certain foods may play a role in affecting symptoms in a small group of people.
Nutrition is essential for maintaining the body's functions, and the brain is no exception. Nutrients provide the brain with energy and support neurotransmitter function, cell membrane integrity, and neuron communication. In the case of ADHD, the effects of inadequate nutrition may exacerbate existing symptoms.
Several studies have found a link between diet and ADHD symptoms. A Korean study of 986 school-age children with ADHD and learning disabilities found that a high intake of sweetened desserts, fried foods, and salt was positively associated with learning, attention, and behavioral problems. In contrast, a balanced diet with regular meals and a high intake of dairy products and vegetables was negatively associated with these problems. Another study found that higher consumption of sweetened beverages was associated with a 40% greater likelihood of ADHD symptoms in children over seven years old.
Additionally, specific nutrient deficiencies have been linked to ADHD symptoms. For example, zinc deficiency has been associated with ADHD symptom severity, with lower blood and hair zinc levels correlated with higher ratings of inattention. Omega-3 fatty acid deficiencies may also play a role, as they are essential for brain health and inflammation control. Supplementation with omega-3 fatty acids has been shown to reduce impulsiveness in children with ADHD. Vitamin D deficiencies have also been linked to ADHD, with lower levels found in children with ADHD compared to those without. Supplementation with vitamin D, along with prescription medication, has shown improvement in hyperactivity, inattention, and behavior scores.
While dietary changes alone may not be sufficient to manage ADHD symptoms, ensuring a balanced and nutritious diet can support overall brain health and potentially ease specific symptoms.

The use of elimination diets and restricted diets
Elimination diets involve removing foods or ingredients that may trigger certain behaviours or worsen symptoms. ADHD diets have not been extensively researched, and the data is limited and mixed. However, many health experts believe that diet and nutrition can play a role in managing ADHD symptoms.
The idea of elimination diets for ADHD was first introduced in the 1970s by Feingold, an allergist who suggested that children allergic to aspirin may also react to synthetic food colours and natural salicylates. This led to the Feingold diet, which eliminates foods with natural salicylates, synthetic colours, and flavours. While initial studies showed a small effect size, setting the tone for skepticism about elimination diets, more recent higher-quality studies have found a reliable link between synthetic colours and ADHD symptoms based on parent ratings.
There are three main types of elimination diets: "oligoantigenic," "multiple food," and "single food." The oligoantigenic or "few foods" diet is the most common in research studies due to its restriction of a small number of foods, although it is challenging to maintain. A 2011 study published in The Lancet found that children with ADHD on an oligoantigenic elimination diet showed a 64% improvement in symptoms after five weeks, while those on a normal "healthy" diet showed no change. Other double-blind studies have reported that 30% of children with ADHD responded positively to elimination diets.
The process of an elimination diet involves removing potential trigger foods for three weeks and then slowly reintroducing them to observe any behavioural changes. Common trigger foods include gluten, soy, wheat, dairy, nuts, and artificial food dyes. Elimination diets require strict discipline and consistency, and they can be challenging to maintain, especially during busy periods.
While there is no solid evidence that specific foods or diets directly affect ADHD symptoms, nutritional meals are essential for brain function. A well-rounded diet with complex carbohydrates, high-protein foods, and omega-3 fatty acids is recommended for overall health and may support brain health in individuals with ADHD.
It is important to note that dietary changes should not replace prescribed medical treatments for ADHD. Elimination diets can lead to nutritional deficiencies, especially in children, so they should be approached with caution and under professional guidance.
