Harvard says: These are the 5 foods that very intelligent people eat.

The brain , although not a muscle, requires a constant and adequate supply of nutrients to perform its cognitive functions , such as memory, concentration, learning, and reasoning. Therefore, consuming foods rich in vitamins, minerals, antioxidants, and essential fatty acids helps improve its performance and enhances its benefits . If you want to be smarter, these are the 5 foods you shouldn't miss.

A diet rich in these foods can improve memory, concentration, and learning, as well as protect the brain against aging and neurodegenerative diseases. On the other hand, according to Harvard Medical School , the best foods are those that not only protect the brain but also care for the heart and blood vessels, such as:

1. Green leafy vegetables (spinach, cabbage, broccoli), rich in vitamin K, lutein, folic acid and beta-carotene, which help delay cognitive decline and promote better brain function.

2. Fatty fish (salmon, tuna, cod), which provide omega-3 fatty acids and unsaturated fats essential for reducing inflammation, promoting neuronal transmission, and improving mental performance. It is recommended to eat fish at least twice a week, choosing varieties low in mercury.

3. Berries (blueberries, raspberries, strawberries), which contain antioxidant flavonoids that protect the brain from oxidative stress, improve memory, and enhance brain plasticity. 4. Tea and coffee, beverages that provide caffeine and antioxidants that can improve mental function, increase concentration, and facilitate the consolidation of new memories.

5. Nuts (walnuts, almonds, seeds), sources of protein, healthy fats, and alpha-linolenic acid (a type of omega-3) that contribute to improving memory and cardiovascular health, thus promoting cognitive function.

Are there other ways to have a healthy brain?

While a balanced, nutrient-rich diet is essential for proper brain function, several complementary strategies play a key role in maintaining mental and cognitive health throughout life. The Mayo Clinic lists the following:

- Regular physical activity: Aerobic exercise, such as walking, running, or swimming, increases cerebral blood flow, which boosts memory and helps prevent age-related cognitive decline.

- Adequate rest: Sleeping between 7 and 9 hours a night is vital for the brain to process and consolidate the information acquired during the day. Sleep also repairs neural connections and improves intellectual performance.

- Cognitive stimulation: Engaging in activities that challenge the brain—such as learning new things, reading, solving puzzles, playing an instrument, or learning a language—stimulates neuroplasticity and strengthens the mind, maintaining mental agility.

- Active social relationships: Interacting and maintaining ties with family, friends, or social groups promotes emotional health, reduces stress, and activates brain areas related to empathy and communication.

- Stress and emotion management : Practicing relaxation techniques such as meditation, mindfulness, or deep breathing helps control stress, protecting the brain from disorders linked to anxiety and depression.
