12 foods to boost brain function

The foods we eat can have a big impact on the structure and health of our brains. Eating a brain-boosting diet can support both short- and long-term brain function.
The brain is an energy-intensive organ, using around 20 percent of the body’s calories, so it needs plenty of good fuel to maintain concentration throughout the day.
The brain also requires certain nutrients to stay healthy. Omega-3 fatty acids, for example, help build and repair brain cells, and antioxidants reduce cellular stress and inflammation, which are linked to brain aging and neurodegenerative disorders, such as Alzheimer’s disease.
This article explores the scientific evidence behind 12 of the best brain foods.


Oily fish are a good source of omega-3 fatty acids. Omega-3s help build membranes around each cell in the body, including the brain cells. They can, therefore, improve the structure of brain cells called neurons.

2017 study found that people with high levels of omega-3s had increased blood flow in the brain. The researchers also identified a connection between omega-3 levels and better cognition, or thinking abilities.
These results suggest that eating foods rich in omega-3s, such as oily fish, may boost brain function.
Examples of oily fish that contain high levels of omega-3s include:
  • salmon
  • mackerel
  • tuna
  • herring
  • sardines
People can also get omega-3s from soybeans, nuts, flaxseed, and other seeds.

Dark chocolate contains cocoa, also known as cacao. Cacao contains flavonoids, a type of antioxidant.
Antioxidants are especially important for brain health, as the brain is highly susceptible to oxidative stress, which contributes to age-related cognitive decline and brain diseases.
Cacao flavonoids seem to be good for the brain. According to a 2013 review, they may encourage neuron and blood vessel growth in parts of the brain involved in memory and learning. They may also stimulate blood flow in the brain.
Some research also suggests that the flavonoid component of chocolate may reverse memory problems in snails. Scientists have yet to test this in humans.
However, a 2018 study in humans also supports the brain-boosting effects of dark chocolate. The researchers used imaging methods to look at activity in the brain after participants ate chocolate with at least 70 percent cacao.
The researchers concluded that eating this type of dark chocolate may improve brain plasticity, which is crucial for learning, and may also provide other brain-related benefits.

Like dark chocolate, many berries contain flavonoid antioxidants. Research suggests that these may make the berries good food for the brain.
Antioxidants help by reducing inflammation and oxidative stress. The antioxidants in berries include anthocyanin, caffeic acid, catechin, and quercetin.
2014 review notes that the antioxidant compounds in berries have many positive effects on the brain, including:
  • improving communication between brain cells
  • reducing inflammation throughout the body
  • increasing plasticity, which helps brain cells form new connections, boosting learning and memory
  • reducing or delaying age-related neurodegenerative diseases and cognitive decline
Antioxidant-rich berries that can boot brain health include:
  • strawberries
  • blackberries
  • blueberries
  • blackcurrants
  • mulberries

Eating more nuts and seeds may be good for the brain, as these foods contain omega-3 fatty acids and antioxidants.
2014 study found that a higher overall nut intake was linked to better brain function in older age.
Nuts and seeds are also rich sources of the antioxidant vitamin E, which protects cells from oxidative stress caused by free radicals.
As a person ages, their brain may be exposed to this form of oxidative stress, and vitamin E may therefore support brain health in older age.
2014 review found that vitamin E may also contribute to improved cognition and reduced risk of Alzheimer’s disease.
The nuts and seeds with the highest amounts of vitamin E include:
  • sunflower seeds
  • almonds
  • hazelnuts
Fully exploring vitamin E’s effects on the brain will require further research.

Eating whole grains is another way to benefit from the effects of vitamin E, with these grains being a good source of the vitamin.
Whole-grain foods include:
  • brown rice
  • barley
  • bulgur wheat
  • oatmeal
  • whole-grain bread
  • whole-grain pasta

Coffee is a well-known concentration aid — many drink it to stay awake and encourage focus.
The caffeine in coffee blocks a substance in the brain called adenosine, which makes a person feel sleepy.
Beyond boosting alertness, a 2018 study suggests that caffeine may also increase the brain’s capacity for processing information.
The researchers found that caffeine causes an increase in brain entropy, which refers to complex and variable brain activity. When entropy is high, the brain can process more information.
Coffee is also a source of antioxidants, which may support brain health as a person gets older. One study has linked lifelong coffee consumption with reduced risk of:
Caffeine can, however, affect a person’s sleep and doctors do not recommend caffeine consumption for everyone.

A source of healthful unsaturated fat, avocados may support the brain.
Eating monounsaturated fats may reduce blood pressure, and high blood pressure is linked with cognitive decline.
Thus, by reducing high blood pressure, the unsaturated fats in avocados may lower the risk of cognitive decline.
Other sources of healthful unsaturated fats include:
  • almonds, cashews, and peanuts
  • flaxseed and chia seeds
  • soybean, sunflower, and canola oils
  • walnuts and Brazil nuts
  • fish

Peanuts are a legume with an excellent nutritional profile. They contain plenty of unsaturated fats and protein to keep a person’s energy levels up throughout the day.
Peanuts also provide key vitamins and minerals to keep the brain healthy, including high levels of vitamin E and resveratrol.
Resveratrol is a natural non-flavonoid antioxidant found in peanuts, mulberries, and rhubarb. Evidence from a review article suggests that resveratrol can have protective effects, such as helping to prevent cancers, inflammation, and neurological diseases, including Alzheimer’s and Parkinson’s.

Enjoyed by many for breakfast, eggs can be an effective brain food.
They are a good source of the following B vitamins:
Recent research suggests that these vitamins may prevent brain shrinkage and delay cognitive decline.

As well as being a low-calorie source of dietary fiber, broccoli may be good for the brain.
Broccoli is rich in compounds called glucosinolates. When the body breaks these down, they produce isothiocyanates.
Isothiocyanates may reduce oxidative stress and lower the risk of neurodegenerative diseases.
Broccoli also contains vitamin C and flavonoids, and these antioxidants can further boost a person’s brain health.
Other cruciferous vegetables that contain glucosinolates include:
  • brussels sprouts
  • bok choy
  • cabbage
  • cauliflower
  • turnips
  • kale

Leafy greens, including kale, may support brain health.
Like broccoli, kale contains glucosinolates, and leafy greens also contain other key antioxidants, vitamins, and minerals. This is why many consider kale to be a superfood.

Soybean products are rich in a particular group of antioxidants called polyphenols.
Research has linked polyphenols with a reduced risk of dementia and improved cognitive abilities in regular aging processes.
Soy products contain polyphenols called isoflavones, including daidzein and genistein. These chemicals act as antioxidants, providing a range of health benefits throughout the body.

In addition to making dietary changes, some people consider taking supplements to improve their brain function. But do these supplements actually work?
Taking vitamins B, C, or E, beta-carotene, or magnesium may improve brain function if a person has a deficiency in any of them. If a person does not have a deficiency, these supplements are unlikely to improve mental performance.
Research suggests that taking ginseng may improve this performance. However, further studies are needed before doctors can recommend ginseng to enhance brain function.

The foods listed above may help improve a person’s memory and concentration. Some may also reduce the risk of stroke and age-related neurodegenerative diseases, such as Alzheimer’s and Parkinson’s.
Some of the foods contain compounds such as healthful fatty acids, which can help improve the structure of brain cells called neurons. Other compounds, such as sugars and saturated fats, may damage brain cell structures.
Brain-boosting foods tend to contain one or more of the following:
  • antioxidants, such as flavonoids or vitamin E
  • B vitamins
  • healthful fats
  • omega fatty acids
Beyond adjusting the diet, a person can optimize their brain function by:
  • not eating too much or too little
  • getting enough sleep
  • keeping hydrated
  • exercising regularly
  • reducing stress through yoga, mindfulness, or meditation
  • reducing alcohol intake
Eating a brain-boosting diet will also provide many benefits for the entire body.

What are the effects of racism on health and mental health?

Racism, or discrimination based on race or ethnicity, is a key contributing factor in the onset of disease. It is also responsible for increasing disparities in physical and mental health among Black, Indigenous, and people of color (BIPOC).
This article looks at some of the ways that racism can affect health, how a person can live healthfully while facing the burden of racism, and how socioeconomic factors associated with racism can continue to pose risks to both physical and mental health.

Racism can affect a person’s health in a variety of ways.
2015 systematic review collated the results of almost 300 studies to look at how racism affects the physical and mental health of Asian American, African American, and Latinx American people.
The sections below will detail the conclusions of this review, as well as those of other studies.

Physical health

The aforementioned systematic review found that experiencing racism is associated with poor mental health and, to a lesser extent, poor physical health.
There is considerable research to suggest that the stress associated with experiencing racism can have long lasting physical effects.
Stress can elevate blood pressure and weaken the immune system, which, in turn, raises the risk of developing long-term health conditions.
Racism is associated with higher rates of stress, increasing a person of color’s risk of developing high blood pressure. In fact, the Centers for Disease Control and Prevention (CDC) report that Black people are more likely to have hypertension than any other racial or ethnic group.
Stress as a result of racism can also lead to behaviors that may cause further risk to physical health. For example, research has found that discrimination is linked to higher rates of smoking, alcohol use, drug use, and unhealthful eating habits.
Also, a 2019 study found that racist experiences appear to increase inflammation in African American people, raising their risk of developing chronic conditions such as heart disease and kidney disease.
Another study found that unfair treatment of people of color has a significant consequential effect on sleep and physiological functioning in midlife.
Many studies have cited structural racism within medical care as a key factor in poor physical health. For example, a 2016 study into racial bias and pain management found a link between undertreating pain in Black patients and false biological beliefs, such as, “Black people’s skin is thicker than white people’s skin.”
2015 study found that compared with other racial groups, Black children with severe pain from appendicitis are less likely to receive pain medication. This suggests that racial bias is causing medical professionals to use different thresholds of pain for different racial groups, either inadvertently or purposefully, before administering care.

Mental health

The 2015 meta-analysis found that racism is twice as likely to affect mental health than physical health. Of those the researchers sampled, BIPOC who reported experiences of racism also experienced the following mental health issues:
2011 meta-analysis of studies into racism and mental health among Asian American people also revealed significant relationships between racial discrimination and depression and anxiety.
2018 paper suggested that fear of racism itself is harmful, and that it can undermine good mental health characteristics, such as resilience, hope, and motivation. The paper also underlined how verbal and physical assault can cause PTSD.

The American Academy of Pediatrics (AAP) are so concerned about how racism affects the well-being of young people that they released a 2019 policy statement on it.
The statement says that failure to address racism in the United States “will continue to undermine health equity of all children, adolescents, emerging adults, and their families.”

Physical health

Racism is already linked to poorer birth outcomes, such as infant mortality, for BIPOC. Studies suggest that mothers who report experiences of racism are more likely to have babies with a low birth weight, which can cause further health problems for the infants later in life.
Just as with older BIPOC, young people also experience the ongoing stress of living with and witnessing racism and discrimination. As young BIPOC get older, they have similar risks of developing chronic health conditions as their parents.

Mental health

The AAP recommend that young people who report experiences of racism should undergo routine assessment for mental health conditions, including:
  • PTSD
  • anxiety
  • grief
  • depression
The AAP also say that even if children do not directly experience racism themselves, they can be just as significantly affected by witnessing racism as those who experience it firsthand.
Intense and persistent stress can influence how the brain develops, intensifying negative emotions such as fear and impacting learning and memory.

BIPOC alone should not carry the burden of coping with racism. Everyone needs to address structural disadvantage, socioeconomic deprivation, and institutionalized racism to reduce discrimination.
However, there is evidence to suggest that certain factors can help people cope with the negative effects of racism, both physically and mentally.
The sections below will discuss these factors in more detail.

Talk about racist experiences with others

Many studies have suggested that talking about racist experiences, instead of bottling them up, can help a person process feelings of stress, anger, and frustration.
Similarly, engaging with — instead of ignoring — racism is likely to be beneficial.

Foster a strong sense of racial identity

Studies into racism and its effects on mental health have found that BIPOC who felt strongly about their racial identity were less likely to be distressed by racism and less likely to be physically or mentally affected by it.
Therefore, having a well-developed sense of ethnic or racial identity may help blunt or buffer the effects of racism. However, research must continue in this area, as findings are still limited.

Lean on friends and family

Having a network of people to talk to for support, advice, and comfort can help people cope with racial discrimination. It can encourage a sense of security and identity and reduce negative thoughts and feelings.
Some studies have also found that having a strong support network may even combat depression.

According to the American Psychological Association, socioeconomic status can directly affect both physical and mental health. Researchers have linked low socioeconomic status and a lack of economic development to poor health and a shorter life expectancy.

Physical health

According to a 2017 analysis of 1.7 million people, having a low socioeconomic status can be as bad for a person’s health as smoking, drinking a lot of alcohol, or eating an unhealthful diet.
People with low socioeconomic status are also more likely to have avoidable medical procedures and hospitalizations, as well as conditions that go untreated.

Mental health

Reduced access to housing, employment, and mortgage lending due to low socioeconomic status can adversely affect mental health and increase feelings of depression, stress, and anxiety.
Although Hispanic and African American people seem to have a lower risk of mental health conditions than those in other racial or ethnic groups, those who do develop such conditions tend to have more persistent psychological issues.
However, it is worth noting that this perceived lower risk may be due to racial inequities in the healthcare system.
Also, although there is an association between socioeconomic status and race, there is not perfect correspondence between race and low socioeconomic status. Indeed, even among BIPOC of middle and upper socioeconomic status, the effects of racism on mental and physical health persist.

Racism can be a key factor in the onset of physical and mental health issues in BIPOC.
Research suggests that the stress that develops due to experiencing or witnessing racism can have long lasting effects, increasing the risk of chronic disease and mental health conditions such as anxiety and depression in both children and adults.
Utilizing the support of peers and community, forging a strong sense of racial identity, and talking about racist experiences can all be effective ways of coping with the stress of racism.
Research suggests that low socioeconomic status has the same impact on physical health as smoking, heavy alcohol use, or an unhealthful diet. Racial groups with higher levels of low socioeconomic status also tend to have more persistent mental health conditions.
