The Best Foods to Boost Your Brain Function


As the control center of your body, the brain is in charge of keeping your heart beating, lungs breathing and allowing you to move, feel and think.  That is why it is essential 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.  
Here is a list of foods that enhance your brain function.

(1) Fatty Fish

When people talk about brain foods, fatty fish is usually at the top of the list.  This type of fish includes salmon, trout and sardines, which are all rich sources of omega-3 fatty acids.  About 60% of your brain is made of fat, and half of that fat is the omega-3 kind.  Your brain uses omega-3s to build brain and nerve cells, and these fats are essential for learning and memory.

Omega 3-s may also slow age-related mental decline and help ward off Alzheimer’s disease.  On the flip side, not getting enough omega-3s is linked to learning impairments, as well as depression.  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.

(2) Coffee

If you are a coffee fan you’ll be glad to hear that it’s good for you.  Two main components in coffee — caffeine and antioxidants — are terrific for brain health.  The caffeine in coffee has a number of positive effects on the brain, including increased alertness, improved mood and sharpened concentration.  Caffeine keeps your brain alert by blocking adenosine, a chemical messenger that makes you sleepy.  Drinking coffee over the long term is also linked to a reduced risk of neurological diseases, such as Parkinson’s and Alzheimer’s.  This could at least be partly due to coffee’s high concentration of 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.  Antioxidants act against both oxidative stress and inflammation, conditions that may contribute to brain aging and neurodegenerative diseases.  Some of the antioxidants in blueberries have been found to accumulate in the brain and help improve communication between brain cells.  Animal studies have shown that blueberries help improve memory and may even delay short-term memory loss.


Broccoli is packed with powerful plant compounds, including antioxidants and vitaminK.  This fat-soluble vitamin is essential for forming sphingolipids, a type of fat that’s densely packed into brain cells.  A few studies in older adults have linked a higher vitamin K intake to better memory.  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.

(6) Pumpkin Seeds

Pumpkin seeds contain powerful antioxidants that protect the body and brain from free radical damage.  They’re also an excellent source of magnesium, zinc and copper.  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.
  • Magnesium: Magnesium is essential for learning and memory. Low magnesium levels are linked to many neurological diseases, including migraines, depression and epilepsy.
  • 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. 

(7) Dark Chocolate

Dark chocolate and cocoa powder are packed with 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.  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.  

(8) Nuts

A 2014 review showed that nuts can improve cognition and even help prevent neurodegenerative diseases.  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.  Several nutrients in nuts, such as healthy fats, antioxidants and vitamin E, may explain their brain-health benefits.  Vitamin E shields cell membranes from free radical damage, helping slow mental decline.  While all nuts are good for your brain, walnuts may have an extra edge, since they also deliver omega-3 fatty acids.  

(9) Eggs

Eggs are a good source of several nutrients tied to brain health, including vitamins B6 and B12, folate and choline.  Choline is an important micronutrient that your body uses to create acetylcholine, a neurotransmitter that helps regulate mood and memory.  Research has shown that higher intakes of choline are linked to better memory and mental function.  Furthermore, the B vitamins have several roles in brain health.  They may help slow the progression of mental decline in the elderly, and being deficient in two types of B vitamins — folate and B12 — has been linked to depression.  Folate deficiency is common in elderly people with dementia, and studies show that folic acid supplements can help minimize age-related mental decline.  

(10) Green Tea

As is the case with coffee, the caffeine in green tea boosts brain function, improving alertness, performance, memory and focus.  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.  L-theanine also increases the frequency of alpha waves in the brain, which helps you relax without making you feel tired.  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.
