Your brain is kind of a big deal.

As the control center of your body, it's in charge of keeping your heart beating and lungs breathing and allowing you to move, feel and think.

That's why it's a good idea to keep your brain in peak working condition.

The foods you eat play a role in keeping your brain healthy and can improve specific mental tasks, such as memory and concentration.

This article lists 11 foods that boost your brain.

1. Fatty Fish

When people talk about brain foods, fatty fish is often at the top of the list.

This type of fish includes salmon, trout and sardines, which are all rich sources ofomega-3 fatty acids (1Trusted Source).

About 60% of your brain is made of fat, and half of that fat is the omega-3 kind (2Trusted Source).

Your brain uses omega-3s to build brain and nerve cells, and these fats are essential for learning and memory (2Trusted Source,3Trusted Source).

Omega 3-s also have a couple additional benefits for your brain.

For one thing, they may slow age-related mental decline and help ward off Alzheimer's disease (4Trusted Source, 5Trusted Source, 6Trusted Source, 7Trusted Source).

On the flip side, not getting enough omega-3s is linked to learning impairments, as well as depression (3Trusted Source,8Trusted Source).

In general, eating fish seems to have positive health benefits.

One study found that people who ate baked or broiled fish regularly had more gray matter in their brains. Gray matter contains most of the nerve cells that control decision making, memory and emotion (9Trusted Source).

Overall, fatty fish is an excellent choice for brain health.

SUMMARY:Fatty fish is a rich source of omega-3s, a major building block of the brain. Omega-3s play a role in sharpening memory and improving mood, as well as protecting your brain against decline.

2. Coffee

If coffee is the highlight of your morning, you'll be glad to hear that it's good for you.

Two main components in coffee — caffeine and antioxidants — help your brain.

The caffeine in coffee has a number of positive effects on the brain, including (9Trusted Source):

  • Increased alertness: Caffeine keeps your brain alert by blocking adenosine, a chemical messenger that makes you sleepy (10Trusted Source, 11Trusted Source,12Trusted Source).
  • Improved mood: Caffeine may also boost some of your "feel-good" neurotransmitters, such as serotonin (13).
  • Sharpened concentration: One study found that when participants drank one large coffee in the morning or smaller amounts throughout the day, they were more effective at tasks that required concentration (14Trusted Source).

Drinking coffee over the long term is also linked to a reduced risk of neurological diseases, such as Parkinson's and Alzheimer's (9Trusted Source).

This could at least be partly due to coffee's high concentration of antioxidants (15Trusted Source).

SUMMARY:Coffee can help boost alertness and mood. It may also offer some protection against Alzheimer's, thanks to its caffeine and antioxidants.

3. Blueberries

Blueberries provide numerous health benefits, including some that are specifically for your brain.

Blueberries and other deeply colored berries deliver anthocyanins, a group of plant compounds with anti-inflammatory and antioxidant effects (16Trusted Source).

Antioxidants act against both oxidative stress and inflammation, conditions that may contribute to brain aging and neurodegenerative diseases (16Trusted Source).

Some of the antioxidants in blueberries have been found to accumulate in the brain and help improve communication between brain cells (16Trusted Source, 17Trusted Source).

Animal studies have shown that blueberries help improve memory and may even delay short-term memory loss (18Trusted Source,19Trusted Source, 20Trusted Source).

Try sprinkling them on your breakfast cereal or adding them to a smoothie.

SUMMARY:Blueberries are packed with antioxidants that may delay brain aging and improve memory.

4. Turmeric

Turmeric has generated a lot of buzz recently.

This deep-yellow spice is a key ingredient in curry powder and has a number of benefits for the brain.

Curcumin, the active ingredient in turmeric, has been shown to cross the blood-brain barrier, meaning it can directly enter the brain and benefit the cells there (21Trusted Source).

It's a potent antioxidant and anti-inflammatory compound that has been linked to the following brain benefits:

  • May benefit memory: Curcumin may help improve memory in people with Alzheimer's. It may also help clear the amyloid plaques that are a hallmark of this disease (21Trusted Source, 22Trusted Source).
  • Eases depression: It boosts serotonin and dopamine, which both improve mood. One study found curcumin improved depression symptoms just as much as an antidepressant over six weeks (23,24Trusted Source).
  • Helps new brain cells grow:Curcumin boosts brain-derived neurotrophic factor, a type of growth hormone that helps brain cells grow. It may help delay age-related mental decline, but more research is needed (25Trusted Source).

To reap the benefits of curcumin, try cooking with curry powder, adding turmeric to potato dishes to turn them golden or making turmeric tea.

SUMMARY:Turmeric and its active compound curcumin have strong anti-inflammatory and antioxidant benefits, which help the brain. In research, it has reduced symptoms of depression and Alzheimer's disease.

5. Broccoli

Broccoli is packed with powerful plant compounds, including antioxidants (26Trusted Source).

It's also very high in vitamin K, delivering more than 100% of the Recommended Daily Intake (RDI) in a 1-cup (91-gram) serving (27).

This fat-soluble vitamin is essential for forming sphingolipids, a type of fat that's densely packed into brain cells (28Trusted Source).

A few studies in older adults have linked a higher vitamin K intake to better memory (29Trusted Source, 30Trusted Source).

Beyond vitamin K, broccoli contains a number of compounds that give it anti-inflammatory and antioxidant effects, which may help protect the brain against damage (31Trusted Source).

SUMMARY:Broccoli contains a number of compounds that have powerful antioxidant and anti-inflammatory effects, including vitamin K.

6. Pumpkin Seeds

Pumpkin seeds contain powerful antioxidants that protect the body and brain from free radical damage (31Trusted Source).

They're also an excellent source of magnesium, iron, zinc and copper (32).

Each of these nutrients is important for brain health:

  • Zinc: This element is crucial for nerve signaling. Zinc deficiency has been linked to many neurological conditions, including Alzheimer's disease, depression and Parkinson's disease (33Trusted Source, 34Trusted Source, 35Trusted Source).
  • Magnesium: Magnesium is essential for learning and memory. Low magnesium levels are linked to many neurological diseases, including migraines, depression and epilepsy (36Trusted Source, 37Trusted Source).
  • Copper: Your brain uses copper to help control nerve signals. And when copper levels are out of whack, there's a higher risk of neurodegenerative disorders, such as Alzheimer's (38Trusted Source, 39Trusted Source).
  • Iron: Iron deficiency is often characterized by brain fog and impaired brain function (40Trusted Source).

The research focuses mostly on these micronutrients, rather than pumpkin seeds themselves. However, since pumpkin seeds are high in these micronutrients, you can likely reap their benefits by adding pumpkin seeds to your diet.

SUMMARY:Pumpkin seeds are rich in many micronutrients that are important for brain function, including copper, iron, magnesium and zinc.

7. Dark Chocolate

Dark chocolate and cocoa powder are packed with a few brain-boosting compounds, including flavonoids, caffeine and antioxidants.

Flavonoids are a group of antioxidant plant compounds.

The flavonoids in chocolate gather in the areas of the brain that deal with learning and memory. Researchers say these compounds may enhance memory and also help slow down age-related mental decline (41Trusted Source, 42Trusted Source, 43Trusted Source, 44Trusted Source).

In fact, a number of studies back this up (45Trusted Source, 46Trusted Source, 47Trusted Source).

In one study including over 900 people, those who ate chocolate more frequently performed better in a series of mental tasks, including some involving memory, than those who rarely ate it (45Trusted Source).

Chocolate is also a legitimate mood booster, according to research.

One study found that participants who ate chocolate experienced increased positive feelings, compared to participants who ate crackers (48Trusted Source).

However, it's still not clear whether that's because of compounds in the chocolate, or simply because the yummy flavor makes people happy (48Trusted Source).

SUMMARY:The flavonoids in chocolate may help protect the brain. Studies have suggested that eating chocolate could boost both memory and mood.

8. Nuts

Research has shown that eating nuts can improve markers of heart health, and having a healthy heart is linked to having a healthy brain (49Trusted Source, 50Trusted Source).

A 2014 review showed that nuts can improve cognition and even help prevent neurodegenerative diseases (51Trusted Source).

Also, another large study found that women who ate nuts regularly over the course of several years had a sharper memory, compared to those who didn't eat nuts (49Trusted Source).

Several nutrients in nuts, such as healthy fats, antioxidants and vitamin E, may explain their brain-health benefits (52Trusted Source,53Trusted Source).

Vitamin E shields cell membranes from free radical damage, helping slow mental decline (54Trusted Source, 55Trusted Source, 56Trusted Source).

While all nuts are good for your brain,walnuts may have an extra edge, since they also deliver omega-3 fatty acids (57).

SUMMARY:Nuts contain a host of brain-boosting nutrients, including vitamin E, healthy fats and plant compounds.

9. Oranges

You can get all the vitamin C you need in a day by eating one medium orange (58).

Doing so is important for brain health, since vitamin C is a key factor in preventing mental decline (59Trusted Source).

Eating sufficient amounts of vitamin C-rich foods can protect against age-related mental decline and Alzheimer's disease, according to a 2014 review article (60Trusted Source).

Vitamin C is a powerful antioxidant that helps fight off the free radicals that can damage brain cells. Plus, vitamin C supports brain health as you age (61Trusted Source).

You can also get excellent amounts of vitamin C from bell peppers, guava, kiwi, tomatoes and strawberries (62).

SUMMARY:Oranges and other foods that are high in vitamin C can help defend your brain against damage from free radicals.

10. Eggs

Eggs are a good source of several nutrients tied to brain health, including vitamins B6 and B12, folate and choline (63).

Choline is an important micronutrient that your body uses to create acetylcholine, a neurotransmitter that helps regulate mood and memory (64Trusted Source, 65Trusted Source).

Two studies found that higher intakes of choline were linked to better memory and mental function (66Trusted Source, 67Trusted Source).

Nevertheless, many people don't get enough choline in their diet.

Eating eggs is an easy way to get choline, given that egg yolks are among the most concentrated sources of this nutrient.

Adequate intake of choline is 425 mg per day for most women and 550 mg per day for men, with just a single egg yolk containing 112 mg (64Trusted Source).

Furthermore, the B vitamins have several roles in brain health.

To start, they may help slow the progression of mental decline in the elderly (68Trusted Source).

Also, being deficient in two types of B vitamins — folate and B12 — has been linked to depression (69Trusted Source).

Folate deficiency is common in elderly people with dementia, and studies show that folic acid supplements can help minimize age-related mental decline (70Trusted Source,71Trusted Source).

B12 is also involved in synthesizing brain chemicals and regulating sugar levels in the brain (69Trusted Source).

It's worth noting that there's very little direct research on the link between eating eggs and brain health. However, there is research to support the brain-boosting benefits of the nutrients found in eggs.

SUMMARY:Eggs are a rich source of several B vitamins and choline, which are important for proper brain functioning and development, as well as regulating mood.

11. Green Tea

As is the case with coffee, the caffeine ingreen tea boosts brain function.

In fact, it has been found to improve alertness, performance, memory and focus (72Trusted Source).

But green tea also has other components that make it a brain-healthy beverage.

One of them is L-theanine, an amino acid that can cross the blood-brain barrier and increase the activity of the neurotransmitter GABA, which helps reduce anxiety and makes you feel more relaxed (73, 74Trusted Source, 75).

L-theanine also increases the frequency of alpha waves in the brain, which helps you relax without making you feel tired (76Trusted Source).

One review found that the L-theanine in green tea can help you relax by counteracting the stimulating effects of caffeine (72Trusted Source).

It's also rich in polyphenols and antioxidants that may protect the brain from mental decline and reduce the risk of Alzheimer's and Parkinson's (77Trusted Source, 78Trusted Source).

Plus, green tea has been found to improve memory (79Trusted Source).

SUMMARY:Green tea is an excellent beverage to support your brain. Its caffeine content boosts alertness, while its antioxidants protect the brain and L-theanine helps you relax.
