Mild dehydration can reduce brain energy and lead to memory impairment. Experts suggest taking at least 1200ml a day, which is equivalent to 6 cups a day.
2. Edible fiber
Regulate brain energy supply. Dietary fiber helps to continuously regulate brain energy supply. Foods rich in fiber include raisins, broccoli, green beans, spinach, almonds, kiwis, oranges, pears, apples with skins, barley and brown rice.
3. Tyrosine protein: Stimulate brain power
In addition to neurons, there are neurotransmitters that help the brain transmit signals. Lack of important neurotransmitters such as tyrosine and tryptophan will lead to brain dysfunction. Eating more foods rich in this nutrition will help to refresh your mind and improve your attention. Such as dairy products, eggs, seafood, soybeans and so on.
4. Antioxidants: Protect the brain
With the increase of age, free radicals will attack brain cells with the blood system. If no antioxidant is added to inhibit it, it will lead to the gradual loss of brain memory. Foods rich in antioxidants include berries, such as blueberries, broccoli, carrots, garlic, purple grapes, spinach, soybeans, tea, tomatoes and whole grains.
5. Vitamins and trace elements: essential "building materials"
Some vitamins and minerals are essential "building materials" for the brain. Among them, the most critical nutrients include: vitamin B6, vitamin B 12, vitamin C, iron, calcium and so on. If it is lacking, it will lead to learning disabilities. You can eat some oats, milk and kiwi fruit in moderation.
6. Dopamine: It helps to improve memory.
Dopamine is a neurotransmitter. Researchers from the German Center for Neurodegenerative Diseases and the University of magdeburg divided the subjects between the ages of 65 and 75 into two groups. One group took levodopa, which can be converted into dopamine in the brain, and the other group took a placebo as a control. A few hours later, the researchers asked them to take a memory test. The results showed that a group of elderly people who took levodopa better recognized the photos they had seen six hours ago.
