Foods that Will Help Improve Memory and Intelligence
The brain is the main command center of the entire body, it controls all physiological processes, from heartbeat to breathing, allowing us to move, feel, think, remember, remember, make decisions, in short, live life to the fullest.
Therefore, it is so important to maintain his health and performance. Here are the foods that recent scientific research shows you should regularly include in your diet:
1. Fatty sea fish
Salmon, trout, tuna, herring, and sardines contain a lot of omega-3 polyunsaturated fatty acids. The brain is approximately 60% fat, and more than half of these fats are omega-3 fatty acids.
These substances are needed for the formation of neurons and new neural connections, as well as for the growth and development of other brain tissue cells.
As confirmed by the results of a systematic review published in 2022 in the journal Cureus, omega-3s are absolutely essential for good cognitive function – memory, thinking and learning, as well as for normal blood circulation in the brain.
In addition, research shows that omega-3s slow age-related decline in intelligence and help prevent the development of Alzheimer’s disease , and a lack of these fatty acids leads to cognitive impairment and depression . There is also scientific evidence that people who regularly eat fatty fish have more gray matter in their brains. Gray matter contains nerve cells that control memory, decision-making, and emotions.
2. Coffee
The main components of coffee that are beneficial for brain health are caffeine and antioxidants (natural substances that protect cells from damage by free oxygen molecules). Caffeine has several positive effects:
- Activates the brain by blocking the action of adenosine, a substance that ensures the transmission of signals between cells and plays a role in suppressing alertness;
- Improves mood by stimulating the production of the “pleasure hormone” dopamine;
- Improves concentration.
In addition, if you drink 3-4 cups of coffee a day for a long time, you will reduce the risk of Parkinson’s and Alzheimer’s diseases. This may be due to the high concentration of antioxidants in coffee.
However, do not forget that if you drink too much coffee, or drink it right before going to bed, it can lead to sleep disturbances, which will negatively affect the health of the brain and its functions.
3. Blueberries
Blueberries, blueberries, lingonberries, cranberries and other bright blue, purple, violet, and red berries contain anthocyanins – plant pigments that have powerful anti-inflammatory and antioxidant effects, which are especially useful for protecting against brain aging and neurodegenerative diseases.
In addition, research shows that some blueberry antioxidants accumulate in the brain and help improve communication between cells.
4. Turmeric
It is a bright yellow spice and a key ingredient in curry. Its active ingredient, curcumin, is able to cross the blood-brain barrier and enter the brain. Curcumin is a powerful antioxidant and anti-inflammatory agent that:
- Improves memory in people with Alzheimer’s disease, and even helps clear brain tissue of amyloid plaques;
- Relieves symptoms of depression as it stimulates the production of “good mood hormones” serotonin and dopamine.
- Promotes the growth of new brain cells, as it stimulates the production of neurotrophic factor – a specific growth hormone. This may slow down age-related decline in mental abilities.
However, it is worth noting that most of the studies are talking about very high doses of curcumin, 500-2000 milligrams per day, which is much higher than you can get from just eating curry.
5. Broccoli
Broccoli contains many bioactive plant compounds, including antioxidants. In addition, this cruciferous vegetable is very high in vitamin K—a 160-gram cup of cooked broccoli contains more than 100% of the recommended daily value.
This fat-soluble vitamin is important for the formation of sphingolipids, a type of fat found in brain cells. High intake of vitamin K improves memory and intelligence in older people. Broccoli is also high in sulforane, an antioxidant that reduces inflammation and protects brain cells from damage.
6. Pumpkin seeds
Pumpkin seeds are an excellent source of antioxidants and other micronutrients that benefit brain health, including:
- Zinc. This chemical element plays a key role in signaling connections between nerve cells. Zinc deficiency is associated with many neurological and psychiatric diseases, including depression, Alzheimer’s and Parkinson’s diseases;
- Magnesium. This element is very important for memory and learning ability. Low magnesium levels underlie many neurological disorders, including migraine, epilepsy and depression;
- Copper. The brain uses copper to control the exchange of signals between neurons. Copper deficiency may contribute to the development of Alzheimer’s disease.
- Iron. Iron deficiency is often accompanied by brain fog and decreased cognitive function.
7. Dark chocolate
Chocolate, which contains at least 70% cocoa beans, contains many brain-boosting compounds, including flavonoids and caffeine.
Flavonoids are plant substances with antioxidant properties that improve memory and help slow down age-related mental decline.
One study also showed that dark chocolate not only improves mood, but also promotes diversity in the composition of the intestinal microbiome, that is, it acts as a prebiotic – food for beneficial intestinal bacteria. Since there is a proven direct connection between the gut and the brain, improving the composition of the gut microbiome may directly affect the brain, helping to improve mood, scientists suggest.
8. Nuts
Research shows that nuts are good for the heart, and heart health is associated with brain health and a reduced risk of neurological diseases.
In addition, the regular presence of nuts in the diet reduces the risk of intellectual decline in older people. Nuts contain healthy fats, antioxidants, and vitamin E, which is why they are so good for the brain. For example, vitamin E protects brain cells from damage from free oxygen molecules.
While all nuts are good for brain health, walnuts are especially beneficial because they contain omega-3 fatty acids.
9. Oranges
Oranges are very high in vitamin C (you can get almost your entire daily requirement of this vitamin by eating just one medium-sized fruit). High levels of vitamin C in the blood prevent age-related decline in intelligence, and also improve concentration, memory, attention and speed of decision-making.
In addition, vitamin C is a powerful antioxidant that protects brain cells from damage and aging, reducing the risk of developing depression, anxiety, schizophrenia and Alzheimer’s disease.
A lot of vitamin C is also found in sweet peppers, kiwi, strawberries, and tomatoes.
10. Eggs
Eggs are an excellent source of brain-healthy micronutrients such as vitamins B6 and B12, folate and choline. Choline is an essential trace mineral needed by the body to synthesize acetylcholine, a neurotransmitter that helps regulate mood and memory. Choline is produced in small quantities in the liver, but the bulk of this substance must be obtained from food.
High intake of foods containing choline is associated with improved memory and cognitive function.
Keep in mind that one egg contains 147 milligrams of choline, with the recommended intake for women being 425 and for men 550 milligrams per day.
The B vitamins present in eggs are also very important for brain health. These vitamins help slow age-related mental decline because they reduce levels of homocysteine, an amino acid that plays a role in the development of dementia and Alzheimer’s disease.
Deficiency of folate and vitamin B12, as studies show , leads to the development of depression. Additionally, folate deficiency is common in patients with dementia, and folic acid supplementation may minimize age-related cognitive decline. Vitamin B12 appears to play an important role in the synthesis of chemicals in the central nervous system, and helps regulate sugar levels in the brain.
11. Green tea
Green tea contains a lot of caffeine, which, as already mentioned, activates the brain and improves performance, memory and concentration.
But in addition to caffeine, green tea contains the amino acid L-theanine, which is able to overcome the blood-brain barrier and enter the brain from the blood, increasing the activity of gamma-aminobutyric acid (GABA), the most important inhibitory neurotransmitter of the central nervous system. As a result, you calm down and relax.
In addition, green tea is rich in polyphenols (plant antioxidants), which protect against intellectual decline and reduce the risk of neurodegenerative diseases. Moreover, one study showed that green tea helps improve memory.
