1. Healthy fat: improve brain cells. Brain cell structure mainly includes healthy fat, the most important of which is omega-3 fatty acid. The brain needs to constantly repair itself and increase neurons, so it needs more and better omega-3 fatty acids. Foods rich in this fatty acid include salmon, tuna, linseed oil, rapeseed oil, walnut, wheat germ oil and eggs.

2. Antioxidants: Protect the brain. With age, free radicals will attack brain cells with the blood system. If antioxidants are not added to curb them, 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.

3. Tyrosine protein: stimulate brain power. In addition to neurons, there are nerve conduction substances 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 kind of nutrition will help to refresh your mind and improve your attention. For example, dairy products, eggs, seafood, soybeans and so on.

4. water: rehydrate the brain. Slight dehydration will reduce brain energy and lead to memory impairment. Experts suggest taking at least1200ml a day, which is equivalent to 6 cups a day.

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, etc. If lacking, it will lead to learning disabilities. You can eat some oats, milk, kiwi fruit and so on in moderation.

6. Dietary 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.
