There are countless billions of nerve cells in the human brain that are constantly carrying out heavy activities. Scientific research has confirmed that diet is not only a necessity to maintain life, but also plays a very important role in the normal operation of the brain. Some foods help to develop people's intelligence, make people's thinking more agile, concentrate more, and even stimulate people's creativity and imagination.

Nutrition and health care experts have found that some foods that help to strengthen the brain and improve intelligence are not expensive and hard to find, but cheap and ordinary things, which can be seen everywhere in daily life. The following foods are very beneficial to the brain, so mental workers and school students may wish to choose foods frequently.

1, milk. Milk is a nearly perfect nutrient. It is rich in protein, calcium and essential amino acids for the brain. Calcium in milk is most easily absorbed by people and is an indispensable and important substance for brain metabolism. In addition, it also contains vitamin B 1 and other elements that are very beneficial to nerve cells. If you have excessive insomnia with your brain, a cup of hot milk before going to bed will help you fall asleep.

2. eggs. Brain activity function and memory intensity are closely related to acetylcholine content in the brain. Experiments have proved that the beauty of eating chicken is that when lecithin in egg yolk is decomposed by enzymes, it can produce rich acetylcholine, which can reach brain tissue quickly after entering the blood and enhance memory. Foreign studies have confirmed that eating 1 or 2 eggs a day can supply enough choline to the body, which is of great benefit to protecting the brain and improving memory.

3. fish. They can provide high-quality protein and calcium for the brain. The fatty acids contained in freshwater fish are mostly unsaturated fatty acids, which will not cause arteriosclerosis and do no harm to cerebral arteries and vessels. On the contrary, they can also protect the cerebral vessels and promote the activity of brain cells.

4, monosodium glutamate. The main component of monosodium glutamate is sodium glutamate, which can be converted into glutamic acid under the action of gastric acid. Glutamate is the only amino acid involved in human brain metabolism, which can promote intellectual development and maintain and improve brain function. Regular intake of monosodium glutamate is helpful to improve mental retardation and memory impairment. Because monosodium glutamate can increase acetylcholine in the brain, it also has a certain effect on neurasthenia.

5. peanuts. Peanut is rich in lecithin and cephalin, which is an important substance needed by nervous system. It can delay the decline of brain function, inhibit platelet aggregation and prevent cerebral thrombosis. Experiments show that eating peanuts regularly can improve blood circulation, enhance memory and delay aging, which is a veritable "longevity fruit".

6. Xiaomi. Vitamin B 1 and B2 in millet are 1.5 times and 1 times higher than those in rice, respectively, and protein contains more tryptophan and methionine. Clinical observation shows that eating millet can prevent aging. If you usually eat more millet porridge and rice, it is beneficial to the health care of your brain.

7. corn. Corn germ is rich in unsaturated fatty acids such as linoleic acid, which can protect cerebrovascular and reduce blood lipid. Especially, the high water content of glutamic acid in corn helps to promote the metabolism of brain cells. Eating some corn often, especially fresh corn, has a brain-strengthening effect.

8. Day lily. People often say that day lily is a "girl without sorrow" and can "soothe the nerves and relieve depression". Note: Daylily should not be eaten raw or fried alone to avoid poisoning. It is best to eat it dry and cooked.

9. Chili. The content of vitamin C in pepper ranks first among all vegetables, and it is also rich in carotene and vitamins. Capsaicin contained in pepper can stimulate taste, increase appetite and promote blood circulation in the brain. In recent years, it has been found that the "spicy" taste of pepper is also a hormone in the human body that stimulates the pursuit of career success, making people energetic and active in thinking. Red peppers are better eaten raw.

10, spinach. Spinach is cheap and humble, but it is a brain-nourishing vegetable. Because spinach is rich in vitamins A, C, B 1 and B2, it is one of the "best suppliers" of brain cell metabolism. In addition, it also contains a lot of chlorophyll, and it also has the function of strengthening the brain and improving intelligence.

1 1, orange. Oranges contain a lot of vitamins A, B 1 and C, which are typical alkaline foods and can eliminate the harm of a lot of acidic foods to the nervous system. Eating oranges in moderation during the exam can make people energetic. In addition, lemon, citrus, grapefruit and so on. It has a similar effect and can replace oranges.

12, pineapple. Pineapple contains a lot of vitamin C and trace element manganese, and it is low in calories. Often eat shengjin refreshing effect. Some people call it a fruit that can improve people's memory. Pineapple is often the favorite fruit of some musicians, singers and actors, because they have to memorize a lot of music scores, lyrics and lines.

How to improve memory and learning efficiency

In the process of learning English, students complain most about memorizing words. They often say that they can't remember, but they always remember and forget. This is actually a common phenomenon. Now I want to talk about my personal views on this phenomenon.

I also studied English, and now I teach English. My overall view on learning English is that it can only be regarded as a kind of pure physical labor and needs to be repeated. I mean that learning English requires repeated memorization.

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

The enemy of memory is forgetting. The essence of improving memory is to avoid and overcome forgetting as much as possible. As long as you exercise consciously and master the laws and methods of memory in learning activities, you can improve and improve your memory.

The following are 10 ways to enhance memory:

1, focus. When remembering, only by concentrating, concentrating, and eliminating distractions and external interference, the cerebral cortex will leave a deep memory trace, which is not easy to forget. If you are distracted and concentrate on doing two things, the memory efficiency will be greatly reduced.

2. Strong interest. If learning materials and knowledge objects are boring, it will be hard 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.

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

6, often recall. When learning, constantly trying to recall can correct the mistakes in memory, make up for the omissions in memory, and make the important and difficult points in the learning content more firmly remembered. When you are free, you can often recall the objects you have remembered in the past, and you can also avoid forgetting them.

7. Audio-visual combination. We can use the functions of language and visual and auditory organs at the same time to strengthen memory and improve memory efficiency. This is much better than reading silently alone.

8, a variety of means. Flexible use of classified memory and chart memory can shorten the memory process according to the situation. Or make an outline, take notes, make cards and other methods to enhance memory.

9. The best time. Generally speaking, the best memory time is 9- 1 1 in the morning, 3-4 in the afternoon and 7- 10 in the evening. It will be much better to use the above time to remember the difficult points and learning materials.

10, use your brain scientifically. On the basis of maintaining the brain by ensuring nutrition, active rest and physical exercise, use the brain scientifically. Only by preventing excessive fatigue and maintaining a positive and optimistic mood can the working efficiency of the brain be greatly improved. This is the key to improving memory.

The core of 10' s method of improving memory introduced above can be summarized as: cultivating interest, concentrating, mastering laws and methods, and paying attention to scientific principles.

In the actual operation process, cultivating interest and concentration is mainly reflected in the classroom. So how to concentrate in class and enhance learning autonomy? This is what I ask students: first, make clear what they want to achieve, let them have the desire to yearn for and pursue, force them to concentrate, remind and urge them to complete their tasks at all times; Second, relying on the ability of self-control and self-adjustment, we will fight against all kinds of external struggles with strong will, and achieve the artistic conception of superego by turning a deaf ear and braving the wind and waves.

Mastering laws and methods and stressing scientific principles should run through the whole learning process of students. This learning process has three steps: the first step, preview, the second step, class, and the third step, review. Preview is to know yourself, mainly what you don't know.

Students can mark these difficulties with their own unique symbols. In class, we should not only grasp the difficulties mentioned by the teacher, but also dare to question our own "blank" in order to achieve the purpose of learning from each other. If every student can do this, then the bilateral activity of giving lectures should be not only taught by teachers, but also asked by students. Speaking of class, I want to add one thing, that is, how to take notes. Don't take all your notes, because there must be a difficulty in preparing lessons for teachers, so there must be a difficulty in students' notes. Taking classes is very important because it is an intense mental activity. Basically, this process is finished, and everything else can be solved. So I ask students to "move" all kinds of senses together, that is, heart, mouth, eyes, ears and hands. Because modern psychology shows that it is extremely important for all kinds of senses to participate in activities at the same time to improve the working efficiency of the brain. The role of review lies in "checking for leaks and filling gaps". Make your own review plan according to your personal situation. The main purpose of the plan should be to consolidate learning achievements and improve learning efficiency.

23 1 How to improve memory?

First, understanding memory, understanding is the basis of memory, understanding memory takes a short time and has a good effect. Second, interest memory. By making up stories. Play games. Mouth formula, homophonic and other ways make boring things more vivid. Third, associative memory. Use close association, relational association and comparative association to remember. Fourth, repeat memory. The law of forgetting is fast first and then slow. Therefore, after mastering it, you have to remember it again and again. Fifth, collaborative memory. In the process of memory, hands, brain, mouth and ears will participate together, and the effect will be better. Sixth, systematically summarize memories. On the basis of analyzing materials, knowledge is organized and systematized through lists and outlines. This can improve the memory effect. 3| Comments
