A Study on Breakfast for Senior High School Students A Study on Breakfast for Senior Two (5) Class B2 Staff Introduction: Instructor —— Guan Yanbin (Chinese) Team Leader —— Member Di Anli —— Wang Qin Gu Lei, Chen Yang, Ren Yanan and the subjects involved in the research: the subject —— the leading subject involved in the research on healthy breakfast for senior high school students —— the non-leading subject involved in the research on Chinese nutrition —— other middle schools in mathematics and biology. Abstract: Through organizing activities in the group, we feel that our classmates don't know much about healthy breakfast and arrange breakfast reasonably, and they don't pay much attention to it, especially in the usual contact between our group members and classmates, we know that many students don't eat breakfast, which is very unfavorable to their health. Therefore, the purpose of our research on this topic is as follows: to understand the importance attached by students around us to breakfast, whether to insist on eating breakfast, and then to have a preliminary understanding of the breakfast problem of contemporary high school students, so as to provide some reference and basis for our future work. Secondly, we will not pay too much attention to how high the research can reach. What we value is the process. We hope that through this research as a platform, those students who don't pay attention to breakfast at present can attract some attention and have a preliminary understanding of healthy breakfast, which is also conducive to students having the opportunity to do this research in the future. This is our original intention and the main purpose of our research. Keywords: healthy breakfast to solve the problem: in the course of a series of research on breakfast, we made some students know the importance of breakfast by distributing questionnaires, which improved the importance of breakfast. At the same time, it also improved the importance of breakfast among the students around us. Significance: around us, many students don't eat breakfast, and some even affect their studies. Five members of our group are aware of the seriousness of this problem. We want to appeal to the students not to. Although our strength is very meager, I believe our research will certainly give you some useful enlightenment. Objective: 1, to make high school students around us know and understand some problems involved in breakfast. 2. Through investigation and publicity, some students who pay little attention to breakfast can pay more attention to it. 3. The health of breakfast is closely related to students' lives, which makes students actively join the ranks of promoting healthy breakfast. 4. Through this activity, our research activities are more perfect, learn from each other's strengths, so that we can do better in the next research project. Suppose: our classmates don't know much about the health and importance of breakfast, but through this research activity, we make our classmates know about it and join the ranks of healthy breakfast. Content: In order to study the high school students' understanding of the importance of healthy breakfast, first of all, we should understand the students' breakfast in a comprehensive and detailed way, make a survey, and introduce and publicize it to everyone. Methods: Questionnaire survey-We will distribute questionnaires to some students in this class and other classes, in order to get a wider understanding of the students' situation. Interview-We will interview some students to find out their views on healthy breakfast and our research. Information consulting method-we can go to the library or online to consult information about healthy breakfast. Statistics-We should know the senior high school students' understanding of some breakfast issues, and make a summary and induction. Personnel arrangement: managing teachers-comprehensively guiding Chen Yang-writing papers-Di Anli-questionnaire design and distribution, Statistical Wang Qin-outreach, interview with Gu Lei-library access and online access to Ren Yanan-input typesetting post-production time in the first week and the second, Three weeks, four weeks, and five weeks, the task was completed. The opening report was distributed, questionnaires and interviews were conducted to find information. Post-production and conclusion were the main research methods. Data inquiry method was used to find information. The main person in charge, all members of Di Anli, Gu Lei and Ren Yanan were completed. The basic process: the first stage: we first discussed the research topics together, determined the topics, assigned their respective tasks, and determined the basic methods. Di Anli finished the opening report. In the second stage, our team members designed the questionnaire together and distributed it to all classes, and took it back in the afternoon. Chen Yang and Wang Qin * * * summarized the results of the questionnaire together. In the third stage, Gu Lei combined the results of the questionnaire, investigated the information on the Internet, checked for missing information, and drew corresponding conclusions. During this period, our team members also conducted a series of discussions and got the results. The first. /SPAN> Conclusion: Through the summary of the questionnaire and the results of the interview, our group learned that most students don't know the importance of breakfast, and there are many people who don't eat breakfast for various reasons. The reasons are summarized as follows: 1. Getting up too late 2. Losing weight 3. Analysis of other results: In fact, everyone doesn't know that skipping breakfast is not only bad for health, but also affects learning efficiency. And it's just the public enemy of losing weight. It's harmful to us as teenagers. It's a pity that students and parents don't pay attention to this point. This needs to be reminded. Suggestion: Therefore, our group hopes that the school will carry out activities and publicity on related content to raise students' attention to this issue, hoping to help everyone. Personal experience and feelings: Di Anli: I personally think this theme is very close to our high school students' lives, so I choose the topic. This is conducive to cultivating our ability, and all our members feel that the department is good. I think we can do better than last time through our efforts. Gu Lei: This time, every member of us actively participated in this study, and made a lot of efforts for this study. At the same time, through this study, I realized more deeply the importance of breakfast for our high school students. I hope all students can pay more attention to breakfast. Wang Qin: I think we have not done very well in some places this time. For example, the questions in the questionnaire survey are not designed comprehensively enough, perhaps because time is pressing, but I believe we will do better next time. Chen Yang: Research-based learning is conducive to cultivating our students' sense of unity. For example, regarding the design of the questionnaire, we finally reached an agreement and determined the questions through heated discussions. At the same time, I have learned more about the importance of breakfast. I am a person who values breakfast, so I hope my classmates around me can pay attention to it. Ren Yanan: I think through our meager strength, we should be able to make our classmates understand the importance of eating breakfast. Teacher's evaluation: In fact, in this research activity, I only helped them discuss and formulate the theme together, and copied the questionnaire, mainly by themselves, which fully shows that they have independent ability, and their research process, including research papers, has made great progress compared with last time, which is commendable.

High school students' healthy diet

Question: High school students eat healthily.

I am a sophomore, a day student. I want to plan my healthy diet well. I hope everyone can help me and give me a good suggestion.

For example, what should I eat in the morning What should I eat at noon? What to eat in the evening? I thanked you in advance here.

Jidi replied:

Eat something nutritious for breakfast, such as eggs, milk or soybean milk, and a little fruit and a piece or two of bread. Morning is the beginning of the day, so don't be careless.

Have a full stomach at noon, because the afternoon is long, and hunger will affect your study. You'd better eat more vegetables and take more vitamins. If you are still hungry in the afternoon, you can add a visible meal, an apple or a cup of yogurt.

Don't eat too much at night, or you will feel sleepy after dinner, which will affect your study at night. But remember not to drink coffee when you are sleepy.

In addition, it is also good to drink a glass of milk before going to bed, which is nutritious and helps people sleep! References: Middle School Diet

First, reasonable nutrition

Senior high school students are in adolescence, and all the officials in the whole body are gradually mature, with vigorous metabolism and active activity, and their activity is higher than that of any age group. This period is also a period of active thinking ability and the strongest memory, and its learning task is very heavy, and it has to face all kinds of exams. Teenagers in high school are the key moment to grow up physically and acquire knowledge. Their cerebral cortex is in a state of high tension for a long time, so we must attach great importance to the nutritional status at this time. In terms of nutrition supply, it should be adapted to the physiological needs of youth development. If the nutrition supply is not timely or malnutrition occurs during this period, the puberty may be delayed by one to two years. In addition, some high school students were below the standard in height, weight and intelligence because of malnutrition in their infancy and childhood. At the beginning of puberty, as long as they can seize the opportunity and give reasonable and good nutritional supplements, they may catch up with normal teenagers. Many facts show that nutrition has a far-reaching impact on teenagers not only in body shape and function, but also in intelligence and emotion. Second, the dietary composition

The diet of senior high school students belongs to a kind of good food in a special range. Dietary nutrition arrangement should be suitable for the physiological and psychological characteristics of senior high school students. In addition to ensuring the special nutrients needed for growth and development, we must also consider the special nutrients that high school students need to supply because of their heavy learning tasks. The dietary quality is higher than that of primary school students. Therefore, canteen managers and parents are required to know more about nutrition knowledge, which is beneficial to the comprehensive, reasonable and balanced dietary nutrition intake of high school students.

1, thermal energy distribution of three meals. According to the study life of senior high school students, there are usually 4-5 classes in the morning, and the brain cell activity is quite intense. Breakfast is particularly important, and the quality and quantity must be guaranteed. Some teenagers have to have an extra meal (bread, cakes, milk, beans, etc.) after the second class in the morning because of their poor appetite or insufficient energy intake for habitual breakfast. To make breakfast (including lunch) take up 30% of the total heat energy, lunch 35%-40% and dinner 30%-35%, the muscle cells of senior high school boys grow at a high speed, and the amount of exercise is generally greater than that of senior high school girls, so the heat supply is about100-300 kcal more than that of female students. The main food for one day, the staple food is 400-600g (/kloc-600g for people over 0/6 years old). Rice, flour, potatoes and miscellaneous grains with high carbohydrate content are used as main raw materials. Non-staple food, fish100-150g, eggs1-2 (duck and goose eggs are also acceptable), appropriate amount of soybeans and bean products, 500-750g of fresh vegetables, 0/50-250g of fruits/kloc, milk and soy milk. Animals with dirty stomachs and blood can be eaten in moderation, 2-3 times a week.

2. Every meal should be well-prepared. You can also mix grain, beans and vegetables. Appropriate collocation of staple food and non-staple food can give full play to the complementary role of protein and improve the utilization rate of protein. Take breakfast as an example, staple food (cereal, rice), non-staple food (marinated eggs, pork floss or small fish), plus a proper amount of fresh vegetables; Among them, non-staple food can also be replaced by bean products such as boiled soybeans, dried beans and tofu. In addition, it is also very important to mix rice and flour and dry olefin. You should not eat porridge and soup in one meal, or eat all dry and thick food without soup. For example, porridge with steamed bread and eggs or beans and their products are more reasonable.

3. Choose foods rich in vitamins and inorganic salts as raw materials. Such as milk, lean meat, seafood and vegetables (green, yellow and red) to ensure the supply of various inorganic salts and vitamins.

4. Prepare a one-week recipe. Cooking should be based on the local economy and the supply of food raw materials. The total intake of various nutrients in a week should meet the gas demand of senior high school students, so as to make the nutrition distribution of each meal reasonable and balanced as far as possible. However, if the intake of various nutrients varies slightly from day to day, and the total amount in a week reaches the standard, there will basically be no nutritional problems, which is sufficient.

5. Eat fresh food and strictly prevent food poisoning.

Third, the eating environment and eating habits

1, the dining environment should be clean, bright and comfortable, and light music can be played when dining. In this way, diners can feel relaxed and happy, eliminate the tension and fatigue of the tiger layer of the brain, and thus increase their appetite.

2. Eat regularly and quantitatively. It can make the secretion of digestive glands and gastrointestinal peristalsis form regular exercise. If eating is irregular and hunger is uneven, it will cause gastrointestinal dysfunction and affect digestion and absorption.

3. Don't overeat. Do not be partial to food and choose food. Overeating easily leads to pancreatitis, acute dyspepsia and gastritis. Prefer to eat this kind of food but not that kind, or eat only a few kinds of food and don't want to eat others, which is called partial eclipse and selective food. You should know that different foods contain different nutrients, and no matter how good a food is, it can't contain all the nutrients.

4. Eat less snacks. Eating more snacks, over time, the body's essential nutrients intake is insufficient, which will lead to malnutrition. On the other hand, when eating snacks, you will bring dirt and bacteria from your hands into your mouth, which is easy to get infected with intestinal diseases.

5. Don't engage in intense mental work or strenuous exercise within half an hour before and after meals. It is not appropriate to read while eating. All these will lead to weakened gastrointestinal peristalsis, decreased secretion of digestive juice, affecting digestion and absorption function, and even causing gastritis or other gastrointestinal diseases in severe cases.

6. Don't get angry while eating. Angry quarrels, crying and sadness not only hinder eating and affect appetite, but also easily lead to indigestion.

Iv. Dietary nutrition under special circumstances

1, nutritional needs and reasonable diet during the examination

During the exam, high school students are in a state of intense mental work, and they often feel dizzy after using their brains for a long time, which is a reaction of low blood sugar and brain hypoxia. Therefore, it is necessary to consider adding more carbohydrate foods from nutrition to avoid the adverse reactions of hypoglycemia and brain hypoxia. It is best to eat more carbohydrate-containing foods such as cereals, beans, tubers, fruits and vegetables, and reduce pure sugar and pure oily foods.

The exam also needs enough protein, because protein directly affects the activity of cerebral cortex, which can increase memory and make people concentrate. Therefore, we should eat milk, eggs, fish, lean meat and beans, which are rich in protein, to improve brain nutrition.

Vitamins and inorganic salts are also essential for high school students who are highly nervous when taking exams. Many experiments have confirmed that students' consumption of water-soluble vitamins during the examination period has increased greatly compared with their usual study and life. Supplementing water-soluble vitamins B 1, B2, C and niacin has a significant effect on eliminating nerve fatigue. Therefore, you should eat more foods rich in water-soluble vitamins before the exam, such as vegetables, fruits, eggs, beans and animal foods. If the students who take the exam are short of vitamin B 1, they will often suffer from burnout, forgetfulness, irritability and loss of appetite. During the examination, high school students study day and night for the exam, and their eyesight is obviously damaged. Especially, the demand for vitamin A will increase when they review their lessons at night, so they should eat more green, red and yellow vegetables and fruits containing more carotene during the examination. There is also an appropriate amount of animal food such as liver and kidney rich in vitamin A, which is beneficial to vision protection.

It has also been thought that taking a few vitamin pills during the exam can solve the problem. In fact, under normal physiological conditions, nutrients cooperate and restrict each other in the body, and various vitamins should be balanced. Simple medication is difficult to achieve a balance, especially during the examination, emphasizing that high school students' nutrition must be comprehensive and reasonable, and it is impossible to rely solely on medication.

Therefore, during the examination, both the school students' canteen and the family should pay attention to the reasonable collocation of food, and try to make the food with high nutritional value, good color, fragrance and taste, which can improve the appetite and ensure the health of the candidates. A snack with high protein quality can be added at night.

2. Nutritional needs during exercise. Good and reasonable nutrition is conducive to eliminating exercise fatigue and restoring physical strength, promoting physical exercise and improving competition results, and also promoting physical development and strengthening physical fitness.

Before the sports meeting, we should choose foods that are hunger-tolerant, low in fiber, rich in calories, high in protein and rich in various vitamins and inorganic salts. Fat meat, leeks and sweet potatoes should be eaten less, because these food residues are easy to produce gas, which will affect practice and competition. In short, the diet during exercise not only emphasizes the quality and quantity of nutrients and the characteristics of color, fragrance and taste, but also needs to be adjusted appropriately in combination with the content of practice competition and temperature. For example, strength-oriented exercises should be supplied with enough high-protein food, speed-oriented exercises should pay attention to the overall balance of nutrients, and endurance-oriented exercises should be supplied with sufficient heat energy, water and inorganic salts. It must be pointed out that teenagers who love sports activities do not pay attention to nutrition or have bad eating habits, such as being hungry and full, or unwilling to increase their food intake for fear of getting fat, which is a serious violation of sports physiology and will inevitably damage their health for a long time.

Middle school students are the future and hope of the motherland, and a healthy body is the capital of revolution. With the development of economy and the continuous improvement of people's living standards, there are some unhealthy phenomena in middle school students' diet: picky eaters, overeating, partial eclipse, dieting, etc., resulting in malnutrition and reduced learning efficiency. So nutrition and health are very important for many middle school students. With the help of this topic, I want students to understand the knowledge of nutrition and health, and how to arrange their "three meals a day" and exercise reasonably.

A reasonable and nutritious diet is of great significance to the healthy growth and study of teenagers. Maybe you will find various excuses, such as: "I am too busy studying to attend to it;" Just eat enough; See how strong I am, do I still need it? " In fact, I used to think so, but I didn't know it until I learned about the research study of middle school students' nutrition and health. In fact, this is not the case. The middle school period is the growth and development period of teenagers' bodies. However, due to the pressure and tension of learning in middle school, we don't pay much attention to our bodies, but this is very bad.

In the investigation, I learned a lot: among all staple foods, corn has the highest nutritional value, and it contains a lot of nutritional and health-care substances, besides carbohydrates, protein, fat and carotene, corn also contains riboflavin, vitamins and other nutrients. These substances are of great benefit in preventing diseases such as heart disease and cancer. Carotene contained in corn is absorbed by human body and converted into vitamin A, which has the function of preventing cancer. Plant cellulose can accelerate the elimination of carcinogens and other toxins; Natural vitamin E has the functions of promoting cell division, delaying aging, lowering serum cholesterol, preventing skin lesions, alleviating arteriosclerosis and brain function decline, and eating more corn can also enhance people's memory and brain power. In addition to corn, there are many fruits and vegetables rich in nutrition: lemon can protect skin and beautify, prevent and treat diseases, supplement calcium and iron, flavor and sterilize; The potassium content of bananas is the highest among all kinds of fruits. Wipe your face with papaya, and wash your hands to remove protein, oil and dirt. It is a good skin cleanser …

From the research study of nutrition and health, I not only learned a lot about nutrition, but also learned the connection with various subjects, which made us learn to apply what we have learned, broadened our horizons and improved our enthusiasm and creativity. At the same time, it also cultivates our innovative consciousness and ability, information processing ability, cooperation spirit and interpersonal skills, scientific spirit and scientific attitude, consciousness and responsibility of paying attention to reality and human development.

Our research topic is middle school students' nutrition and health. Therefore, we conducted a questionnaire survey among friends around us and learned that the nutrition and health of middle school students are not ideal now. I made a survey on nutrition. In fact, nutrition can not cure diseases as we know "medical treatment", but it can preserve health and make our life easier. It is not only a science to study how to solve existing problems, but also a more important duty: to tell people how to prevent, how to avoid some troubles from diet and how to improve their energy through diet! Therefore, we should pay more attention to our own nutrition absorption and healthy development.

Middle school students must pay attention to the reasonable collocation of food in order to obtain all kinds of nutrients necessary for human body, and avoid eating meat or vegetarian food. Pay attention to the complementary role of protein and absorb it better. After the investigation results, we also gained a lot, knowing how to develop good eating habits and pay attention to nutrition and health. I learned from the survey that students who skip breakfast have a high anemia rate.

According to a survey by relevant departments, the anemia rate of students who don't eat breakfast is 100%, the anemia rate of students who don't eat breakfast at home is 23.9%, and the anemia rate of students who eat at home is 8.26%, which shows that skipping breakfast can easily lead to anemia and should be paid attention to by the whole society.

To sum up, we call on every parent to change the old concept of adequate food and clothing nutrition and replace it with a brand-new modern concept of nutrition, and put it into practice so that our children can grow up healthily.

Through investigation, we learned to cooperate, enhanced our communication ability, cultivated our ability to process information, learned to collect and sort out information, and exercised our hands-on operation ability.

This time, we studied the nutrition and health of middle school students. Middle school students are in adolescence and have special nutritional requirements. Adolescence is a vigorous period of human growth and development, and of course it needs extra nutrition. Therefore, we should pay attention to the absorption of nutrients. Due to the intense study and many homework, many middle school students often simply cope with breakfast without paying attention to the reasonable collocation of meals, which leads to insufficient physical development, easy fatigue, emaciation, decreased resistance and even some diseases. Food is rich in nutrients, so the absorption of meals is the main source of our energy. After research, I have gained a lot. At the developmental stage, we should take good care of our nutrition in order to develop healthily.

Breakfast is an important source of energy and nutrients for a day?

A survey conducted in the United States found that the energy intake of children who don't eat breakfast, especially the energy from protein, is obviously higher than that of children who eat breakfast, but the average total energy intake of the whole day is obviously lower than that of the breakfast group. In other words, the intake of lunch and dinner can't make up for the lack of energy intake caused by skipping breakfast. A study by Shanghai Second Medical University found that with the increase of breakfast frequency, the intake levels of nutrients such as energy, protein, thiamine, flavin, iron, calcium, magnesium, selenium and zinc in all primary and secondary school students were significantly higher than those in primary and secondary school students who didn't eat breakfast, indicating that eating breakfast was helpful for primary and secondary school students to get enough energy and nutrients.

In the fierce competition of modern society, everything is very important. Through investigation and research, we have exercised our hands-on ability, and the skills of communicating with others have also given us a lesson in dealing with interpersonal relationships in advance in the future, and also cultivated our innovative consciousness and spirit.

Rao Xinya, Bao Lingxian

With the development of economy and the continuous improvement of people's living standards, there are some unhealthy phenomena in middle school students' diet: picky eaters, overeating, partial eclipse, dieting and so on. As a result, malnutrition is caused and learning efficiency is reduced. Adolescence is the golden age of intellectual investment and physical investment. Only by keeping the "weather" right can we grow up well, be physically strong, think quickly and grow healthily.

Middle school is the most important and favorable period to gain knowledge, health and physical fitness. Good nutrition, proper exercise and reasonable work and rest are three important factors that affect their physical and mental development. The physical development of adolescence is extremely rapid, and all organs are increasing, and the functions of brain, heart, liver and kidney are enhanced. In addition, the intense study and large amount of activities also require more calories and nutrients. Eating a good breakfast is very important, because children have to study for 4~5 hours in a row in the morning and have recess activities, which consumes a lot of energy and various nutrients. If you don't eat breakfast or eat it badly, it will have adverse effects on your study and health. In the last two classes, you will have hypoglycemia reactions such as hunger, dizziness, inattention and palpitation, which will affect your study unfairly and hurt your health. Therefore, you must eat breakfast well. Breakfast energy should account for 30% of the total energy in the whole day.

. As the main meal in a day, the main and non-staple foods for lunch should be rich and varied. For students aged around 15, the answer supplement generally requires eating 50 grams of lean meat, 50 grams of bean products-100 grams and 250 grams of vegetables, and it is best to eat fish 2-3 times a week. The staple food depends on the amount of food.

Dinner energy should account for 30%-35% of the total energy of the whole day, which is basically the same as lunch.

For children with poor appetite, consider eating less and eating more meals.

The final stage of preparing for the exam, after reviewing to a certain extent, is to fight for physical strength in a sense. Whoever is in good health and can stick to the end will have hope of success. Therefore, it is very important to strengthen the nutrition of teenagers in this period. Lack of physical strength and energy is easy to form a vicious circle.

At this stage, parents must attach importance to students' dietary nutrition, and should follow the principle of "having a good breakfast, having a full lunch and having a proper dinner". In addition, because teenagers in this period have to study for several hours after dinner, they should add meals once after dinner and before going to bed, so that they can have four meals a day and make reasonable arrangements.

Students should pay attention to the thickness of lunch and dinner, and push out a car full of leftovers from school. Some lunch boxes are thrown away after only a few bites. It is wrong to waste food. A while ago, a 79-year-old grandfather called the newspaper, reflecting that several primary and secondary schools near his home were wasting food very seriously.
