A few days ago, scholars from Innsbruck Medical University in Austria studied the whole process of the influence of coffee on various parts of the brain. They found that caffeine can improve people's short-term memory.
It is reported that a total of 15 men aged 26-47 participated in this research project. They were not allowed to drink coffee for 12 hours, and they were not exposed to nicotine for four hours. After taking 100 mg of caffeine, they also performed better in a series of memory tests of disordered letters, and people's short-term memory ability was improved.
Scientists say that even though caffeine does improve the brain's short-term memory, it doesn't mean that you should drink coffee for study, because this memory is short-term.
Eating and drinking is a good memory.
Japanese scientists have found that rice wine not only plays a great role in preventing Alzheimer's disease, but also a group of enzyme inhibitors in rice wine can reduce the activity of another group of enzymes in the brain that will affect memory, thus enhancing memory. Besides rice wine, there are many foods that can enhance memory, such as milk, eggs, oranges and pineapples. 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.
Chewing regularly can enhance memory.
Researchers in Britain and Japan have found that chewing stimulates the part of the brain responsible for memory, such as chewing gum to help memory. Researchers believe that the continuous chewing action when chewing gum accelerates the movement of the heart and increases the blood supply from the heart to the head, thus promoting brain activity and improving people's thinking ability. At the same time, chewing promotes saliva secretion, and the area responsible for saliva secretion in the brain is closely related to memory and learning.
A calm mood helps to remember.
American scientists say that keeping your head cool and calm, keeping your concentration and giving your brain a good rest will help improve your memory. A practical way to get this good state is thought massage, which includes gently massaging the whole ear from top to bottom with thumb and forefinger, and touching two acupoints between hairline and eyebrows with fingers of both hands. These methods will promote blood flow, eliminate memory disorders and enhance memory.
Staple food: the source of brain power
The main source of blood sugar is carbohydrates in food, which is a staple food. Some berries also contain more glucose, such as grapes and strawberries. The energy of the brain is mainly provided by the oxidation of glucose in the blood. When the glucose content in human blood is less than 80 mg, the excitability of the brain will decrease, which is characterized by inattention, slow response and decreased analytical and understanding ability. Therefore, it is necessary to ensure that a middle school student's daily staple food intake is above 400 grams.
Animal food and bean products: active brain cells
It is better to supplement protein's animal foods, such as milk, eggs, fish and meat. These are all completely protein. They are rich in eight essential amino acids. They are necessary because they cannot be synthesized in the human body and need to be supplemented by food. Soybean protein in plant protein is also high-quality protein, so you should eat more soy products.
Glutamate in protein plays an important role in the balance of brain excitation and inhibition, and it is one of the indispensable amino acids for active brain cells. Lysine in protein can enhance memory.
Egg yolk and animal viscera: angel of memory
At ordinary times, we often see some reports that egg yolk and animal viscera are easy to harden people's blood vessels and so on. In fact, it is very necessary for the elderly, but for the growing teenagers. Lecithin in fat releases a substance called acetylcholine after metabolism in the body. This substance is a substance that transmits information between brain nerve cells, which stimulates brain nerve cells and promotes the consolidation of conditioned reflex. The more acetylcholine in the brain, the faster the formation of memory and thinking, which can keep people full of energy and good memory. If you want to keep a good memory, you can usually eat more egg yolk, soybeans, lean meat, milk, fish, animal viscera (heart, brain, liver and kidney), carrots, especially the rich lecithin contained in soybeans and egg yolk, which is a rare brain-nourishing food.
Vegetables and fruits: brain-strengthening
Vitamins A, B, C and some trace elements are indispensable for the normal work of the brain, because they are auxiliary substances of the brain's nutritional decomposition enzymes. For example, converting glucose into energy is inseparable from the role of vitamin B, otherwise glucose cannot be converted into energy for the brain. Vegetables, fruits and animal meat have enough vitamins and trace elements. For example,100g spinach contains vitamin A2600 international units, which is equivalent to the content of vitamin A in 8kg Chinese cabbage. It is called carrot, which has the reputation of "little ginseng" and is rich in vitamins.
"Yizhi" nutrition also has taboos.
Don't eat too much at every meal. When stressed, some people can't help eating and drinking, but if they eat too much, the blood in the body will concentrate in the gastrointestinal tract, which will make the brain more chaotic and the memory and thinking ability will become worse. So it's best to eat only seven or eight points full.
Carefully choose food supplements and medicine supplements. Children's review stage is in a state of tension, and the gastrointestinal tract will become particularly sensitive. For the sudden appearance of food (tonic), there will be adaptation obstacles because you are not familiar with the properties of food for a while. If the tonic is improper, it will cause a heavy burden on the gastrointestinal tract, and it will also affect the test scores relatively.
Snacks should be limited. Students studying for the exam should never eat more snacks, because in this extraordinary period, they need protein, carbohydrates, vitamins and minerals. If these nutrients are not supplemented, even if the stomach is full, the nutritional distribution of the body is still in an abnormal state, which will easily lead to the deterioration of the body's metabolism, fatigue and decreased attention and memory. In addition, snacks are generally high in calories. If you eat too much, you may lose control of your weight, which will add a lot of trouble and pressure to the candidates.
