Senior three, but I can't remember clearly, and my grades are below average. what can I do?

1. What food can you eat to improve your memory in a short time?

Generally speaking, under normal circumstances, human blood is alkaline, and it is acidic when the brain is overworked or the physical strength is exhausted. Therefore, if you prefer to eat acidic food for a long time, it will make your blood acidic, and your brain and nerve functions will easily deteriorate, causing memory loss. Foods containing phosphorus, chlorine and sulfur are all acidic foods, such as rice, noodles, fish, meat, duck eggs, peanuts and sugar. Regular consumption will acidify the blood; On the contrary, foods containing sodium, calcium and magnesium are alkaline foods. Kelp is the most alkaline, so you can eat more kelp. In addition, some dried fruits, such as cashews, walnuts and sprouts, are rich in protein, fat, vitamins A and E, and minerals such as calcium, phosphorus and iron, which are helpful to people's memory. Pay attention to food hygiene to prevent the occurrence of gastrointestinal infectious diseases. Eat more staple food before the exam. You can also eat more fruits, especially berries with more glucose, such as grapes and strawberries. If your appetite is too bad, you can take some multivitamin glucose properly. Ensuring adequate protein is good for physical and intellectual development. Students usually need 70 to 80 grams of protein every day, which can be increased appropriately when reviewing exams. In protein, protein among animal foods, such as milk, eggs, fish and meat, is the best. Soy protein is also a high-quality protein, so eat more soy products. Proper intake of fat can enhance memory. Fat contains phospholipids and cholesterol. Phospholipids include lecithin and cephalin, both of which are essential substances for brain memory function. Phospholipid is the main component of adenosine triphosphate and an indispensable high-energy substance for energy metabolism of brain cells. Cholesterol is also necessary for brain activity, especially for students. Therefore, it is harmless for teenagers to eat some high-fat foods properly. Of course, people with hyperlipidemia or obesity should pay attention to control. Phospholipids mainly exist in animal foods, such as milk, eggs, animal liver, lean meat and bean products.

Second, food to increase memory.

Whether a person can have a good memory mainly depends on the functional state of the cerebral cortex. In diet, if you can deliberately choose the next food, it is very beneficial to your body, especially your brain.

Plant class

Eat more soybeans and bean products. Beans are cheap, nutritious, easy to digest and absorb, and have the effects of clearing heat, nourishing yin and regulating spleen and stomach. Bean products, in particular, are rich in protein and eight essential amino acids, which can enhance cerebrovascular function, increase the activity of brain cells, inhibit the accumulation of cholesterol in blood vessels and reduce cardiovascular and cerebrovascular diseases. It is very beneficial to drink a cup of soybean milk or a bowl of tofu in the morning and add some honey or eggs.

seafood

Eat fish regularly. Fish contains less fat and can provide excellent protein, calcium and a lot of vitamin A to the brain, which is simply the "best gift" for nerve cells. Most fish contain unsaturated fatty acids. Has the function of protecting cerebral vessels. It is this truth that people often say that "fish has its brain gold".

fruit

Eat more oranges and bananas. Oranges contain a lot of vitamins A, B 1 C, which are alkaline foods, and can eliminate the damage of acidic foods to the nervous system, which is of great help to the brain and intelligence. Bananas can prevent nerve fatigue. Banana contains a lot of potassium, which is beneficial to maintain human cell function, acid-base balance and improve myocardial function.

insectivorous plant

Eat more pig brain and chicken. Pig brain contains iron, phosphorus, calcium and other minerals and various trace elements. Stewed with pig brain, medlar and lotus seeds can strengthen the brain and improve intelligence. Protein in chicken is of special significance to human health, especially to the brain. Can maintain normal immune function, hormone balance, good muscle contractility and skin elasticity.

garden stuff

Eat more spinach and carrots. Spinach is an excellent nutrient for brain cell metabolism. A large amount of chlorophyll contained in it has the function of strengthening brain and improving intelligence. Carrots contain a lot of vitamins, inorganic salts and calcium. , mainly vitamin A, rich in nutrition, has the reputation of "small ginseng" and is a good brain tonic.

staple

Often eat corn and millet. They can provide a large amount of glucose for brain activity energy, which is unique in that they contain more substances such as protein and vitamin B. This popular food can be beneficial to the brain.

Tobacco and alcohol are chronic "killers" of the brain. In order to enhance memory and strengthen the brain, it is best to stay away from alcohol and tobacco.

Third, how to enhance memory?

Memory is the reflection of past experiences in the human brain. It includes three basic processes: memory, retention, reproduction/recall. Its forms include image memory, concept memory, logical memory, emotional memory, sports memory and so on.

The enemy of memory is forgetting. Improving memory is actually trying to avoid and overcome forgetting. As long as you exercise consciously and master the laws and methods of memory in learning activities, you can improve and improve your memory. Here are ten ways to enhance your memory.

1. Attention. As long as you concentrate on your memory and eliminate distractions and external interference, the cerebral cortex will leave a deep and unforgettable memory trace. If you are distracted and concentrate on doing two things, the memory efficiency will be greatly reduced.

2. Strong interest. If you are not interested in learning materials and knowledge objects, it will be difficult to remember even if you spend more time.

3. Understand memory. Understanding is the basis of memory. Only what is understood can be firmly and permanently remembered. It's not easy to learn by rote. For important learning content, if we can combine understanding with reciting, the memory effect will be better.

4. Overstudy. That is to say, on the basis of remembering the learning materials, remember them several times more to achieve the degree of memorizing and remembering. The best degree of over-learning is 150%.

5. Review in time. The speed of forgetting is fast first and then slow. While the iron is hot, reviewing and consolidating what you have just learned is an effective means to strengthen memory traces and prevent forgetting.

6. Always remember. When studying, constantly trying to recall can correct memory mistakes, make up for omissions, and make the hard-to-remember learning content stronger. When you are free, you can often recall the objects you have remembered in the past, and you can also avoid forgetting them.

7. Combine reading, thinking, watching and listening. We can use the functions of language and visual and auditory organs at the same time to strengthen memory and improve memory efficiency. Much better than a single silent reading.

8. Use a variety of memory methods. According to the situation, flexible use of memory methods such as classified memory, characteristic memory, homophonic memory, argument memory, associative memory, interesting memory, chart memory, shortening memory and compiling outline, taking notes and cards can all enhance memory.

9. Master the best memory time. Generally speaking, 9 ~ 1 1 in the morning, 3 ~ 4 in the afternoon and 7 ~ 10 in the evening are the best memory time. Use the above-mentioned hard-to-remember learning materials, and the effect is better.

10. Use your brain scientifically. On the basis of nourishing and maintaining the brain, active rest and physical exercise, using the brain scientifically, preventing excessive fatigue and maintaining a positive and optimistic mood can greatly improve the working efficiency of the brain. This is the key to improving memory.
