In the modern world, caring for health and longevity has become an important part of many people's lives.
One of the key aspects of health is proper nutrition.
After 40 years, the body requires special care and attention to what products we consume. A properly selected diet can significantly improve brain function, increase concentration and memory.

Omega-3 fatty acids
Foods rich in Omega-3 fatty acids are essential for maintaining brain function. They promote the formation of new neurons and help reduce the risk of dementia.
Omega-3 is found in salmon, sardines, tuna, anchovies and other fish. These useful substances are also found in flax seeds and walnuts.
Antioxidants
To improve memory, it is also important to eat foods rich in antioxidants.
Berries such as blueberries, cranberries and raspberries are high in antioxidants. Green tea and cocoa are two other foods that are rich in these substances.
Vitamin E
Helps protect nerve cells from damage and slows down the aging process of brain cells. It is found in almonds, hazelnuts, avocados, olive oil and spinach.
Vitamin B12, which is necessary for the normal functioning of the nervous system, can be found in seafood such as shellfish, crab and shrimp.
Vitamin B12
Vitamin B12 is important for the functioning of the nervous system. A deficiency of this vitamin can cause anemia and impaired brain function. Excellent sources of vitamin B12 include meat, poultry, eggs, and dairy products.
Folic acid
It plays a key role in the functioning of the nervous system and helps prevent the accumulation of homocysteine, which can damage blood vessels in the brain. It is found in green leafy vegetables, legumes, oranges, and grain products.
Iron
Scientists have proven that consuming iron-rich foods improves cognitive function. Iron is found in red meat, chicken, fish, legumes, and green vegetables.
Potassium
Eating foods rich in potassium helps strengthen the blood vessels in the brain and improves blood circulation.
Bananas, potatoes, tomatoes and beets are good sources of potassium.
Zinc
It is also very important for brain function. It is found in meat, poultry, eggs, legumes and dairy products. It is important to note that excess zinc can be harmful, so it should be consumed in moderation.
There are some foods that have the most pronounced benefits.
Green tea
Contains polyphenols, which have antioxidant properties. In addition, it contains caffeine, which temporarily increases energy and concentration.
Dark chocolate
Rich in flavanols, which can improve blood flow to the brain and enhance cognitive function. It also contains theobromine, which has a stimulating effect on the central nervous system.
It’s important to remember that proper nutrition is only part of a comprehensive approach to health. Regular physical activity, adequate sleep, and stress management are also important for maintaining mental alertness and overall well-being.
Eating foods that improve memory and concentration is an important aspect of maintaining mental alertness after 40.
However, it is worth remembering that proper nutrition should be combined with regular physical activity, adequate sleep, and stress management. All of these factors together can help maintain brain health and high mental performance throughout life.
