I. Background and significance
With the improvement of living standards, the obesity rate has gradually increased. The intense study makes some students eat irregularly and suffer from malnutrition. People are more and more picky about food, which directly affects the health of teenagers. China is in an era of rising, and health is the capital of revolution. How can there be a revolution without capital? Middle school students, as a new force in the rise of China, will ultimately hurt themselves if they treat diet as a child's play. And even the development of the whole country. Therefore, it is urgent to solve the dietary problem of middle school students.
Second, the research process and methods
From the beginning of September, 2008 to the end of June, 2009, we made a preliminary study on the dietary health of middle school students by using the time of carrying out research-based learning activities and other spare time. Methods: Questionnaire survey and information consultation. Three. Research analysis and results
This questionnaire survey * * * sent out 180, and recovered 168, with a recovery rate of 93.3%. The students surveyed are Grade One, Grade Two and Grade Three in Longyou Middle School. The survey found that:
1, single food
It can be seen from the text that this is the ultimate in diet. Due to personal and family factors, this happens to some children who are regarded as the apple of their parents' eye. Some children eat meat, eat big fish and meat all day, and have a plump figure. Some children are obsessed with vegetarianism and eat a cabbage and two green onions every day, so these people are in a very "slim" situation, but these two diets are unhealthy eating habits. It has a great impact on health. Authoritative experts have said in the mass media that according to incomplete statistics, 80% of middle school students suffer from physical diseases caused by picky eaters. This has greatly hindered the healthy development of teenagers.
2. Like snacks
Due to the rapid economic development. Family income is increasing, and food prices in the market are generally low. Some unscrupulous vendors take advantage of middle school students' habit of eating snacks. Taking advantage of this principle of "small profits but quick turnover", we often set off at the school gate or booth, and some even put them next to public toilets. This is chilling. Now middle school students want something exciting because of their good living conditions, which is exactly what vendors want. What I see on the table every day is not math, Chinese and English, but "little master" pastry, prepared potato chips, Dove chocolate and so on. This will cause some students with self-control ability to have abnormal meals and save money on those foods that can stimulate their mouths. As a result, their nutrition is unbalanced, their bodies are small and their limbs are weak. It has greatly hindered the healthy development of teenagers. Let's take "China Middle School Students' Balanced Diet Table" and "Contemporary Middle School Students' Dietary Status" as examples, so that we can find out the problems better.
Nutritional balance diet table for middle school students in China
From the above table, we can clearly see the dietary problems faced by contemporary middle school students.
The current situation of teenagers is not objective. Compared with before, the prevalence rate has not decreased, but there are also complicated phenomena. Diabetes, heart disease, obesity and other senile diseases are spreading to teenagers. Students not only suffer physically and mentally, but also affect their studies. More importantly, they can't bear the important consequences of building the motherland in the future.
Fourth, put forward suggestions.
Teenagers should form the good habit of healthy eating.
1, understand the importance of healthy eating. Diet is the basic condition for human life. To make people live a healthy, happy, energetic and intelligent life, we should not only be satisfied with a full stomach, but also consider a reasonable distribution of diet to ensure that all kinds of nutrients needed by the human body are balanced and sufficient, and can be fully absorbed and utilized by the human body.
2. Master the knowledge of healthy eating. The main reason for students' bad habits is the lack of relevant knowledge and education, so we should arrange our study purposefully and in a planned way.
3. Do a good job in all aspects. Families, schools and students should coordinate and cooperate with each other. Strive to achieve the same goal for students, do a good job in students' healthy diet and ensure that students have a healthy body on the premise of ensuring the completion of learning tasks.
3 meals a day is very important.
How do middle school students reasonably match nutritious and healthy meals a day? In the long-term life practice, people have summed up the dining experience of "eating well early, eating well in the middle and eating less at night", which is well known to all women and children. The so-called "good" means good quality, "full" means sufficient quantity, and "less" means that both quantity and quality should be controlled.
Enjoy your breakfast. According to the experimental research of nutritionists, people who eat well in breakfast (such as milk, eggs, chocolate, malt extract, nutritious bread, etc. Keep your blood sugar level at a normal level all morning, so that both mental workers and manual workers feel energetic and efficient. However, people who don't eat breakfast or have poor breakfast quality have their blood sugar level dropped below normal before 10 in the morning, so they feel weak, dizzy, weak, inattentive and reduce their learning efficiency. In addition, according to statistics, people who don't eat breakfast for a long time or don't pay attention to breakfast have a higher incidence of gastritis, gastric ulcer and gastric cancer.
Eat less for dinner. Eating too much at dinner is too good, which can easily affect sleep, obesity and even illness. People who eat a lot of dinner must have more "energy" for the digestion, absorption and treatment of food, so that they can't sleep well; People reduce their activities at night, consume the least calories during sleep, and secrete more insulin at night than during the day. Eating too much will promote insulin secretion. Too much insulin can convert blood sugar into fat, and too much fat accumulation will lead to obesity.
In daily life, some students often ignore food hygiene or the importance of healthy eating for some reasons, thus disrupting the normal pace of eating life.
5. Develop good eating habits
Eat less fried and exposed food. High temperature will destroy many nutrients and produce aldehydes, oxides, lipids and other substances, which are harmful to human body. Excessive accumulation can lead to poisoning.
2 eat more foods that enhance memory. The diet should be nutritious, light and refreshing, and easy to digest. In particular, you should eat more foods that help to enhance your memory. For example, bananas are rich in mineral potassium, which can prevent mental fatigue. Cabbage, grapes and egg yolk all help to enhance memory; Apricot can improve blood circulation and relieve insomnia caused by mental stress; Fish contains a lot of choline and vitamin C, which can promote brain function.
(3) The heat must be sufficient. Middle school students need more calories than adults, and they should ensure enough staple foods every day, such as steamed bread, sesame cakes, rice, fried dough sticks, cakes, sesame sauce and so on. Non-staple food should also be increased, and vegetables, meat, bean products, milk, eggs and fruits should be eaten every day.
(4) Ensure sufficient supply of high-quality protein to meet the needs of accelerating growth and intellectual development and improving disease resistance. Foods rich in high-quality protein include lean meat, fish, milk, eggs and bean products.
⑤ Calcium, iron, iodine, zinc and other elements should be supplemented. These elements are most needed and most easily lacking by middle school students in adolescence. The human skeleton is mainly composed of calcium and phosphorus. Middle school students need a lot of calcium and phosphorus to supplement in the process of rapid growth. They should choose more vegetables, beans, seafood and milk containing calcium and phosphorus, and drink a glass of milk or soybean milk every day to get more calcium and protein. Adolescence is the most prone to anemia in a person's life, and anemia is mainly caused by iron deficiency. So eat more foods rich in iron and vitamin C, such as lean meat, eggs, liver, fish, vegetables and fruits. The development of gonadal organs reaches its peak in adolescence. Iodine is also an essential trace element for growth and development. Generally, seafood, animal offal and meat are rich in iodine and zinc and can be eaten frequently.
6. Pay attention to all kinds of vitamins. Because middle school students use more eyes, adequate supply of vitamin A helps to protect their eyesight and prevent respiratory infection. Vitamin B is related to energy consumption. Vitamin c can promote the absorption of iron. In the cold season, vitamin D supplementation should also be considered to improve calcium absorption.
⑦ Pay attention to the diversification of diet. Reasonable nutrition is of great significance to the healthy growth and study of teenagers. According to the requirements of nutrition, teenagers should have staple food, non-staple food, meat and vegetables, and try their best to diversify. Reasonable staple food is flour products other than rice, such as noodles, steamed buns, steamed bread, jiaozi and wonton. In addition to eating flour snacks for breakfast, we should also insist on drinking milk or soybean milk.
Pay attention to the eating rules of the four seasons.
In spring, the climate changes from cold to warm, and the temperature changes greatly, which is easy to cause diseases. Therefore, we should take enough vitamins and inorganic salts in our diet and eat more fresh vegetables and fruits, such as oranges and lemons.
Hot summer is the season when the human body consumes the most. Therefore, to replenish water and nutrition in time, we should focus on a light and refreshing diet that can stimulate appetite. You can eat more cold salad, salted duck eggs, salted eggs, bean products, mung beans, fresh vegetables and fruits.
Only by finding the key to middle school students' bad diet can we solve the problem of middle school students' bad diet and put forward effective solutions to correct their bad eating habits and promote health. Only with a strong body can we put more energy into our study.
For the sake of our health and the future of our motherland, let's pay close attention to healthy eating.
