There are still 1 month before the college entrance examination, and senior three students have entered the sprint stage before the exam. Recently, a college entrance examination class in Hubei caused a heated discussion about the collective infusion of amino acids by infusion bottles. Please note-

In the classroom of more than 50 people, nearly half of the students take bottles to study at night! Recently, a picture of "the most difficult class in history" appeared in the official Weibo of a forum. Senior three students in a middle school in Xiaogan, Hubei Province were studying by themselves while playing infusion bottles. In the huge classroom, many students hang a bottle next to their desks. The students are bowing their heads to review while hitting bottles, and the teacher is patrolling the corridor.

According to Gao Pingqiang, director of the school's supervision office, there are students playing amino acids in 20 graduating classes in Grade Three, and nearly half of them are playing in a class of 50 or 60 people.

For the topic of "preparing for the exam by hanging bottles for senior three students collectively", netizens expressed disbelief and complained for the students. Most netizens questioned the role of amino acids, saying that hanging bottles of amino acids is not as good as eating meat. However, some netizens think that it is normal to supplement amino acid energy, so there is no need to make a fuss. Professor Shen, deputy dean of Beijing Chaoyang Hospital affiliated to Capital Medical University and certified nutritionist of the Ministry of Health, said in an interview with the reporter of Science and Technology Daily that intravenous injection of amino acids would cause adverse reactions to infusion.

Intravenous injection of amino acids is risky

Is it useful for students to inject amino acids? Gao Gaoqiang believes that there is no harm at first, and then there is a certain hint. Because the students preparing for the exam are nervous, it should be possible to relieve the students' psychology as much as possible.

"More than 20 children in a class actually choose intravenous injection of amino acids, which is simply ignorance!" Shen said bluntly, not to mention that amino acids have no function of supplementing energy at all. Intravenous injection alone may bring various adverse reactions!

Shen said that "amino acid injection" is a prescription drug, which is mainly suitable for parenteral support for patients with acute and chronic renal insufficiency; Severe renal failure and acute and chronic renal failure caused by major surgery, trauma or septicemia. At the same time, for patients with severe malnutrition, it plays an important role in maintaining the nutrition of critical patients and saving their lives. "Even if it is a seriously ill patient, the doctor must first check it in detail to determine its indications and meet the injection indications before prescribing drugs."

It is understood that the types of compound amino acid injections currently used in clinic are: amino acid injections for nutrition, amino acid injections for plasma exchange, amino acid injections for liver diseases, amino acid injections for kidney diseases, amino acid injections for hemostasis, amino acid injections for children and so on. Different diseases have different injection types, so we must not generalize. It is worth noting that a large amount of compound amino acid injection may cause metabolic acidosis.

"Intravenous amino acids are extremely dangerous. Once an adverse reaction occurs, it can be life-threatening if it is not rescued in time. " Li geng, a pharmacist in the pharmacy department of China-Japan Friendship Hospital, thinks. The great risk of intravenous injection of amino acids lies in the route of administration, because the risk of intravenous injection is greater than that of intramuscular injection, and intramuscular injection is greater than oral administration. Intravenous injection directly affects blood, and water for injection may contain some insoluble particles, which may have serious consequences once it enters blood vessels. Some individuals may also have heat source reaction and rejection reaction during infusion. If the rescue is not timely, it may lead to life-threatening, and the school may not have certain medical conditions.

Li geng stressed that it's best not to inject casually before determining your fitness. Drugs have an adaptability, even if they can improve the physical condition in a short time, it is temporary. I wonder if they can adapt to the college entrance examination. If they can't, they will rely on it. Every drug is three-point toxic, so it will be very troublesome to get an injection before the college entrance examination.

Food collocation is beneficial to supplement amino acids.

Amino acids are divided into essential amino acids and non-essential amino acids, each of which is divided into many types. The best way for people to supplement amino acids should be oral administration and normal diet regulation. If normal people are not short of amino acids, there is no need to supplement them at all. Even if they lack amino acids, everyone needs different kinds.

"Amino acids can be ingested through diet. Generally, meat, poultry, eggs and bean products are rich in content. Therefore, normal people do not need to take extra intake. " Shen explained that the types and contents of amino acids in various foods are different. If the amino acids in protein are properly matched, they can achieve a complementary balance and improve the nutritional value of food, which can get twice the result with half the effort. Shen stressed that the farther the variety of food is, the better, such as the collocation of meat and vegetables; The more food, the better; Eat a little of all kinds of food at the same time. Because a single amino acid is absorbed by the human body, it usually stays in the blood for 4 hours, then reaches various tissues and organs, and then synthesizes protein of various tissues and organs. Different amino acids must arrive at the same time to play a complementary role, otherwise, only one amino acid will be decomposed, and the purpose of supplementing amino acids will not be achieved.

Shen pointed out that the balance and proper supply of amino acids is the basic premise of human health. Lack of any kind of amino acid supply will affect the immune system and other normal functions, making people in a sub-health state and prone to diseases.

Scientific diet to meet the college entrance examination

Shen believes that the role of students in supplementing various nutrients during the college entrance examination is actually extremely limited, and more is the psychological role of parents and students. Even if a certain effect is seen in the short term, the long-term effect must be that the disadvantages outweigh the benefits.

"Children in high school are the strongest period. As long as the lifestyle is correct, there is no problem in welcoming the college entrance examination. " Shen suggested that children's recipes should not be changed greatly before the big exam. While ensuring nutrition, pay attention to eating more fruits and vegetables and supplementing fatty acid-rich ingredients such as nuts and deep-sea fish, which can play a role in strengthening the brain. But eating about 50 grams of nuts a week is enough, and it is not advisable to eat more.

Eating more vegetables, fruits and coarse grains at ordinary times can increase the supply of cellulose, vitamins B and C. Besides studying too long and using their brains frequently, senior three students generally use their eyes too much, so they should increase their intake of vitamin A. Vitamin A is an important nutrient to maintain normal vision, and increasing intake properly helps to protect vision.

At the same time, in summer, you should nourish your heart and eat more red vegetables, such as tomatoes, watermelons and cherries. When the weather is hot, you can eat more bitter vegetables to dispel the heart fire. Usually, you should go to bed late and get up early, and it is best to take a nap, so that you can adjust your state and meet the high-intensity learning task. If you can't take a nap, sitting in the classroom after lunch at noon and closing your eyes 10 minutes can also play a role in rest and conditioning.

Finally, Shen said, if parents really think that their children lack nutrition such as protein, it is better to let them eat an extra boiled egg and drink an extra bottle of milk. For children, "natural intake of nutrition, good rest and exercise are better than any' panacea'".
