Preface

The word "nutrition" is derived from the Latin word "lactation". Nutrition is the material basis for human beings to maintain life and meet the energy needs of the organism for survival, learning and work. In the field of nutrition, the whole process of ingestion, digestion, absorption and utilization of food by human body is usually called nutrition. Nutrients, on the other hand, refer to the substances that ensure the growth, development, reproduction and maintenance of a healthy life of the human body, of which the most important nutrients are carbohydrates, proteins, fats, water, minerals and vitamins. College students are a special group of young people, in the middle and late stages of growth and development, lively and active, with a large amount of exercise, coupled with heavy mental labor and intense study, is the period of their lives when the need for a variety of nutrients is the greatest. However, at present, China's college students know less about the sources of nutrients and food classification, do not know how to match the nutrition, there are many nutritional problems, these problems will affect the growth and learning of college students.

I. Measuring the standard of self-health

Health is not only the absence of physical disability, but also a complete physiological and psychological state and social adaptation. Healthy standards: abundant energy, can comfortably take on daily life and heavy work, and do not feel excessive tension and fatigue, optimistic, positive attitude, willing to take responsibility, not picky, good rest, good sleep, adaptable, adaptable to changes in the external environment, able to resist general colds and infectious diseases, appropriate body weight, body proportionality, standing head, shoulders, arms, coordinated position, bright eyes, quick reaction, eyes and face, and the ability to adapt to the external environment. Bright eyes, quick reaction, eyes and face are not easy to be inflamed, teeth are clean, no caries and pain, gums are normal in color, no bleeding, hair is glossy, no dandruff, muscles are plump, and panels are elastic. The four cornerstones of health: reasonable diet, moderate exercise, abstinence from smoking and alcohol, and psychological balance.

One of the main problems in the diet and nutrition of our college students

Du Yuwen, president of the Association for the Promotion of Student Nutrition and Health, pointed out that there are three major problems in the nutrition and health status of students in China: the first is the lack of nutritional knowledge, and unscientific dietary habits. Second, the dietary structure is unreasonable. The energy supply ratio of cereals and proteins is low, and the fat supply ratio of urban school-age children and teenagers is high. Nutrient intake is insufficient. Micronutrient deficiencies such as calcium, iron, zinc and vitamin A are widespread. Third, physical activity is insufficient. The health impact of poor lifestyles such as skipping breakfast, eating out, drinking alcohol and smoking is becoming increasingly prominent.

1 lack of nutritional knowledge

With the rapid development of the national economy, the people's living standards continue to improve and improve more and more people began to pay attention to diet and nutrition, with the popularization of nutritional science and nutritional hygiene publicity and education, people for a balanced diet and nutritional hygiene has a further understanding. First of all, the diet should contain all the nutrients necessary for the human body proteins, fats, sugars, vitamins, inorganic salts, water, and secondly, the intake of food should be conducive to digestion, absorption, utilization, to be fresh and non-polluting, the production of a reasonable processing to enhance the appetite, and diversification of the color, aroma, taste and beauty, while the calories of the three meals a day should be reasonably distributed, according to the Chinese Nutrition Society recommends that the calories of each meal for breakfast accounted for 30% of total calories, lunch 40% of the calories of a whole day. According to the recommendation of Chinese Nutrition Society, the calories of each meal should be 30% of the total calories of the whole day for breakfast, 40% for lunch and 30% for dinner. College students in our university generally lack nutritional knowledge, and the malnutrition rate is high. The lack of nutritional knowledge among college students varies among different majors. In general, the nutritional knowledge of female students is better than that of male students.

2 Unscientific dietary habits

After entering the university, the daily diet of college students is in the hands of the students themselves. Many students' habits are extremely unscientific, mainly in: 1, most college students' daily diet is not regular, the amount and time of three meals a day are often not fixed. Most students do not have the habit of eating three meals regularly, and most of them do not eat in the school cafeteria. Many college students do not pay attention to eating breakfast, but the phenomenon of eating late-night snacks and snacks is more common, the distribution of three meals is unreasonable, and the distribution of caloric intake of each meal is not uniform.

2, many college students after entering the university, like to eat cold drinks, sugar phenomenon is obvious, college men and women college students sugar intake is generally much more than the standard supply, which makes them weight gain, have the idea of losing weight, of which the majority of girls. 3, a considerable portion of the students, especially in the lower grades of the students have addicted to the habits of the Internet cafes, often outside the bag night, so that the quality of the body has fallen sharply. Often skipping classes, even if the class is depressed, can not pay attention to the lecture. College students also often drink drinks instead of milk and fruit, often binge drinking and so on. There is no good study, living habits also directly affects the students' dietary habits of unscientific, irregular. 4, especially serious, many students think they are young, for the body of the temporary symptoms do not pay enough attention, but do not know that the accumulation of these problems to a certain extent will burst out.

3 dietary structure unreasonable

Chinese Nutrition Society to learn from the lessons of Western and Japanese dietary composition, in China's traditional dietary structure pattern based on the development of China's recent adult reasonable dietary composition indicators, and recommended to the whole country. This dietary composition index is: adults per person per month intake of grain cereals 14 kg, potatoes 3 kg, beans 1 kg, meat 1-5 kg, 500 g of fish, vegetable oil 250 g, 500 g of eggs, 2 kg of milk, 12 kg of vegetables, fruits 3 kg. so that the average daily intake of total energy of 10 MJ, you can achieve a basic balance of dietary nutrients. At present, the boys' diet in colleges and universities is based on cereals and their products, followed by vegetables, melons and tomatoes, and the rest of the animals and meat, beans and their products in that order. Girls diet to vegetables, vegetables and tomatoes, cereals and products, followed by livestock and meat, beans and their products. Boys and girls vegetables, fruits, fish, dairy, egg intake did not meet the requirements, the composition of the diet is not reasonable, the student cafeteria should increase the supply of these foods to meet the requirements of a reasonable dietary structure of students.

Second, the role of balanced diet for college students

The main nutrients needed by the human body are carbohydrates, proteins, fats, vitamins, inorganic salts, water and dietary fiber, etc., which have an important physiological function for the human body. For college students, ensuring scientific nutrition and a balanced diet has the following roles.

Able to replenish physical strength, enhance memory

College students are a special group, they are in the period of adolescent development, metabolism, lively and active, large amount of exercise, while the study of the task of heavy, their growth and development, the effectiveness of learning, high and low, the ability to live and resistance to disease, the effectiveness of labor, the size of the ability to exercise, and so on, have a close relationship with the nutritional hygiene. If they are malnourished, it not only affects their health, but also their ability to learn. If malnutrition, not only affects the health of the body, but also affects their learning and life. Scientific studies have shown that proper improvement of nutritional status and making the diet structure as balanced as possible may have a beneficial effect on the full play of long term memory.

Two strengthen the body, preventing and eliminating diseases

Dietary balance is equivalent to a kind of dietary supplement, on the one hand, replenish the deficiency, that is, replenish the deficiency of the body's qi and blood; on the other hand, it can enhance the body's immune system and reduce the occurrence of diseases. Dietary supplementation is mainly to nourish, treatment as a supplement, it will be dietary nutrition and medication perfectly integrated, both to enjoy the pleasure of food, but also up to the health of the body, prevention and treatment of disease. Most importantly, dietary supplements are better than medicines, as has been the case in the past and present. Through rational nutrition, adherence to physical exercise, can be on heart disease, diabetes and cancer reduction has a certain role in helping, at the same time, intake of food rich in vitamin C, vitamin E and carotene, can make the panel aging slower, and free from the plague of age-related diseases.

Three to ease the mood, adjust the mood

College students are often not calm, impulsive and easy to anger, at the same time on some boring courses easy to produce boredom, which is both for learning and physical are not beneficial. In the human body intake of food, there are some nutrients can improve the mood of people, make it easy and happy. Such as spinach, which is rich in magnesium can make a person's mind and body relaxation; eggs, rich in choline helps to improve memory, mental concentration; melon seeds help to calm the mood and so on. Let college students to understand this knowledge, for its ease of emotion, mood adjustment has a certain role.

Three measures to improve the quality of college students' diet

One of the strengthening of nutrition and health knowledge of college students

Suggested that our school to open more public **** elective courses on diet and nutrition, so that they know nutritional hygiene, guidance and help college students to establish a sense of self-care, and to develop a good dietary habits. At the same time, the cafeteria should be equipped with high-level nutritionists and chefs, strengthen management, and constantly improve the level of dietary nutrition to ensure that students eat healthy. Knowledge of diet and health should be added to the teaching of physical education classes at an appropriate time, and be included in the physical education examination and accounted for a certain percentage. Through these initiatives, the aim is to make students emphasize the importance of dietary habits to physical and mental health. It is obvious that strengthening nutritional education, popularizing nutritional knowledge, and enabling people to form scientific and healthy eating habits can reduce the occurrence of various nutritional diseases, and at the same time enhance the physical quality of the people. Combined with the current situation of the daily life of Chinese college students and the existing problems, it can be seen that attention to and improvement of college students' nutritional health, whether it is for the individual, or the country, and even the society's economic, scientific and civilized development has an important impact.

Part 2

Abstract With the improvement of living standards, people pay more and more attention to their own health. Whether they are old, middle-aged, or teenagers, in the pursuit of health, diet and nutrition is a necessary condition for the pursuit of health. Undoubtedly, college students as an excellent youth group, the future hope of the motherland, the level of its quality will directly affect the future development of our country. Nutrition is the material foundation of high-quality talents, so college students with healthy dietary behavior and good nutritional status is the necessary precondition and foundation for adapting to future social competition.

Keywords: college students' diet; nutrition and health

China *** has always attached great importance to the nutritional health of students, and relevant surveys have shown that the nutritional situation of our people has been improving year by year in recent years, and the related diseases have been decreasing year by year. But because the students for a special group, also subject to numerous research?a href='' target='_blank'>cough barium tomb mowing iii? Tatsuka Tatsuka Tatsuka Tatsuka Tatsuka Tatsuka Tatsuka? Wo Mi flex? Tartar mistletoe south embellished incredibly boo? What is the title? The most important thing to remember is that you have a lot of money to spend on your business. The "A" and the "B" are the same as the "B". What's that? What's the reason for this? The first time I saw the first class in the morning *** ringing, a hand holding the breakfast, a hand holding the book of college students quickly shuttle in the school building, hastily a few mouthfuls down, is the end of the breakfast drinking. This phenomenon exists in almost every college. Nutritionists say that when eating, the body is responsible for the logistics of the parasympathetic nervous excitement, so the digestive tract and digestive gland function is active, blood supply increases, movement is enhanced, secretion increases. Doing exercise at this time, a large amount of blood will be supplied to the skeletal muscles, so much so that the digestive system blood supply is insufficient, which will cause digestion and absorption disorders. Especially in the morning, the energy level in the body is very low, and it is more important to have a good dining environment and atmosphere, not to eat while walking. College students as far as possible in the cafeteria or dormitory with breakfast, do not gulp type meal. Long-term hastily drinking breakfast will not only lead to stomach discomfort, but also cause malnutrition. Experts also said that the nutritional situation of the masses can reflect the situation of the country as a whole, is a reflection of the economic and material development of a country. Therefore, the implementation of nutritional monitoring of the masses is very important, especially the group of college students, which is the future development of the country, should be emphasized.

Dietary irregularity is one of the main factors affecting the health of college students data show that in recent years, dietary irregularity has become one of the main factors in the formation of college students sub-health status. College students to drink a reasonable diet and balance the importance of nutritional food obviously do not know enough, and irregular diet is one of the main causes of digestive diseases. According to relevant information, the proportion of students with irregular daily diet has accounted for 41.9%. Long-term irregular diet will not only cause malnutrition, affect the quality of sleep, and even affect the body's neurohumoral regulation and endocrine regulation, the students' physical health has a great negative impact.

In 2001, a survey and analysis of diet, nutrition, and health status of college students in Shanghai by nutritionist Sun Jianhua showed that there were more picky eaters, partial eaters, and people who had hobbies for certain foods. Women's protein intake is low, especially the consumption of animal protein is low. 2005 nutritionist Xin Bifen on the nutritional status of the University of Central and South China's survey results are: Central and South China's students malnutrition rate of 19.9%, the obesity rate of 26.3%, the dietary protein, fat, carbohydrates and vitamins A, B2, C, calcium and other intake with the standard comparable. 2005 Deng Jie on the nutritional status of Nanjing University Nutritional status survey of college students in 2005, Deng Jie showed that: nutritional good food nutrition and health care thesis accounted for 36.9%, malnutrition accounted for 52.6%, and over-nutrition accounted for 10.5%. Checked the questionnaire survey research data on college students' nutrition knowledge, attitude and dietary behavior in recent years. The statistical results of the data show that most of the students' nutritional knowledge is lacking, and some of them have poor nutritional behaviors, such as skipping breakfast and often eating snacks. Those who cope with meals abound in order to sleep more, many students have the habit of not eating breakfast, and eat more at noon and in the evening think that they can make up for the nutrition of breakfast. Some female college students, taking into account the need to keep fit, also developed the habit of not eating breakfast for a long time, noon can eat on time, but dinner is also worried about getting fat, casually cope with a bite. I do not know, long-term, this loss of nutrients, the lack of the most basic nutritious food brought about by the harm is very big. First of all, one, the harm to the brain. Although the weight of the brain tissue only accounts for 2-3% of human body weight, but the blood flow of the brain per minute is about 800ml, oxygen consumption per minute is about 45ml, sugar consumption per hour is about 5g. two, on the harm of the digestive system. Under normal circumstances, the food eaten the first night after about six hours to empty from the stomach into the intestines. The next day if you eat a bad breakfast, stomach acid and stomach digestive enzymes will go to "digest" the gastric mucous membrane layer. In the long run, the normal function of the cell secretion mucus will be damaged, it is easy to cause gastric ulcers and duodenal ulcers and other digestive diseases. Third, closer to the obese: once the human body realizes the lack of nutrition, the first consumption of carbohydrates and proteins, the last consumption of fat, so do not think that do not eat breakfast will help the consumption of fat. On the contrary, do not eat breakfast, but also make lunch and dinner eat more, slimming not but more fat. Dietary nutrition is a prerequisite for the physical development of college students experts suggest that breakfast must be eaten on time, and the speed of eating can not be too fast. Try to go to the cafeteria to eat, relative to the school around the restaurant, the cafeteria dining environment is much better. In addition, breakfast is not eaten to counteract the slimming plan do not think that do not eat breakfast can be less calorie absorption and therefore lose weight, according to nutritionists have confirmed that breakfast is the least likely to be converted into a fat meal in the day of each person. If you don't eat breakfast every day, you will only eat more at lunch. The ratio of breakfast, lunch and dinner should ideally be 3:2:1, so that the essence of what you eat during the day is consumed at the time when you have the most energy.

Colleges and universities should strive to create a good campus cultural atmosphere suitable for the physical and mental characteristics of students, the formation of a relaxed and orderly spare time environment, to improve the ability of college students to tolerate setbacks and adapt to life, the use of sports science and related scientific knowledge education, teaching students the methods of self-regulation and psychological relaxation. Using a variety of forms of health and health care knowledge propaganda and education, guide students to establish the correct social values, outlook on life; cultivate a good lifestyle, eliminate bad habits food nutrition and testing essay good, learn to self-medical supervision and inspection means to establish a good concept of health and healthy behavior habits. Colleges and universities should be based on the actual needs of students, in order to cultivate college students' sports ability and health awareness as the goal, to open a number of special lectures on sports culture, physical exercise and health, sports knowledge, diet and nutrition and health education training, additional college students to carry out healthy sports professional instructors.

Abstract: At present, most of the Chinese college students are around 18-25 years old, and most of them are around 20 years old. They are in the transition stage from puberty to adulthood, and it is the most exuberant growth and development period in their life, with more complex physiological and psychological changes, and the functions of various organs tend to be more and more mature, with more frequent mental and physical activities, and more active thinking ability. Activity is more frequent, active and agile thinking ability, strong memory, in short, is an important period of growth and knowledge, their growth and development, the effectiveness of learning, the ability to live and resistance to disease, the effectiveness of the labor force, the size of the ability to exercise, etc., and nutritional health has a close relationship to ensure that college students are scientifically reasonable nutrition and balanced diet is essential.

Introduction:

College students are in the critical stage of late puberty, is the most vigorous growth and development of a lifetime, frequent mental and physical activity, thinking ability is active and agile, it is an important period of growth of body and knowledge. Reasonable diet and nutrition can help improve college students' physical fitness and learning efficiency.

The problems of college students' diet and nutrition are learned from Wuhan University's School of Public **** Health, which conducted a questionnaire sample survey on the eating habits and dietary composition of 236 college students, and the results show that: the dietary health of college students is a cause for concern. Only 20% of students adhere to three meals a day. In terms of dietary regularity, only 33.9% were able to ensure the regularity of three meals, and only 24.2% of the students never missed any of the three main meals. Among them, the regularity of male students is worse than that of female students, with more than half of them failing to have breakfast on time. Boys are more fond of sports and playing computer, and once indulged, they can easily delay their meal time. In addition, college students eat randomly, 60% of college students never pay attention to the nutritional combination of food, of which more than half of them eat mainly consider the principle of simplicity, 50.4% of them eat regular emotional good or bad influence. Experts after long-term observation found that a person get up in the morning after not eating breakfast, blood viscosity will increase, and slow flow, over time, will lead to heart attack. Therefore, a hearty breakfast not only makes people in the day's work are full of energy, but also beneficial to the health of the heart. Adhere to eat breakfast than not eat breakfast teenagers to grow strong, disease-resistant, in the school classroom performance is more prominent, listening to the class concentration, comprehension ability, academic performance is mostly more excellent. For the working class, eat a good breakfast, but also do a good job of basic work to ensure that this is because the human brain cells can only get energy from glucose as a nutrient, after a night of not eating and do not eat breakfast, the blood can not guarantee enough glucose supply, time will make people become tired and weak, and even nausea, vomiting, dizziness and other phenomena, can not be energetic into the The main reason for this is the fact that it is not a good idea to have a breakfast. In general, the ideal breakfast to master three elements: meal time, nutritional quantity and main and side food balance with. Generally speaking, it is most appropriate to have breakfast 30 minutes after waking up, because this is the time when people's appetite is the most vigorous. Breakfast should not only pay attention to the quantity, but also pay attention to the quality. According to adult calculations, the amount of staple food for breakfast should be between 150 to 200 grams, calories should be about 700 kilocalories. Of course, the calories needed by people of different labor intensity and age are not the same. In terms of the amount of food and calories, it should account for 30% of the total amount of food and calories of the day for people of different ages. Staple food should generally eat starch-containing foods, such as steamed bread, bean buns, bread, etc., but also appropriate to add some protein-rich foods, such as milk, soy milk, eggs, etc., and then with some small dishes. As long as you take a little initiative, you can have a nutritious breakfast.

1, college students dietary nutrition problems

1.1 Lack of necessary nutritional knowledge

China's college students in general lack of nutritional knowledge, malnutrition rate is higher, the lack of nutritional knowledge of college students in the performance of students in different majors vary. In general, the nutritional knowledge of female students is better than that of male students, and the nutritional knowledge of medical students is better than that of students of other majors.

1.2 Unscientific dietary habits

After entering the university, the daily diet of college students is in the hands of the students themselves. Many students' habits are extremely unscientific, mainly manifested in: 1 Most college students have no regularity in their daily diet, and the amount and time of their three meals a day are often not fixed. Most students do not have the habit of eating three meals regularly, and most of them do not eat in the school cafeteria. Many college students do not pay attention to eating breakfast, but late-night snacks and snacks are more common, the distribution of three meals is unreasonable, and the distribution of calorie intake in each meal is not even.2 Many college students are fond of eating cold drinks and sweets after entering the university, and some of them eat candies and so on while reading, especially female college students have always existed in the problem of eating snacks, either because of the habits they have formed since childhood, or they are used to fill up their hunger after a misplaced meal.3 A considerable A part of the students, especially those in the lower grades, have the habit of indulging in Internet cafes and often pack the night outside, which makes their physical fitness drop sharply. College students also often drink drinks instead of milk and fruit, often binge drinking and so on.

1.3 Unreasonable dietary structure

The reasonable dietary composition recommended by the Chinese Academy of Nutrition is: 14kg of grains and cereals, 3kg of potatoes, 1.5kg of meat, 500g of fish, 500g of eggs, 1kg of legumes, 250g of vegetable oil, 2kg of milk, 12kg of vegetables and 3kg of fruits for each adult per month, so that on average, the total energy intake is 10MJ, which can meet the dietary nutritional requirements. 10MJ, can achieve the basic balance of dietary nutrition. And now

The former college men's diet to cereals and their products, followed by vegetables, melons and tomatoes, the rest of the animal meat, beans and their products, in order. Girls diet to vegetables, vegetables and tomatoes, cereals and products, followed by livestock and meat, beans and their products. The intake of vegetables, fruits, fish, dairy and eggs of both male and female students did not meet the requirements, which shows that the composition of the diet is not reasonable. Nutrient and calorie intake of college students in three meals a day, except for iron intake exceeding the supply standard, other nutrients and calorie do not reach the supply standard. The intake of various nutrients in breakfast was lower than the supply standard, and the intake of Chinese food and dinner was lower than the supply standard, except for carbohydrates and iron. Animal food proteins and legume proteins are less than 1/2 of the total proteins, and legume proteins only account for less than 5%, indicating that the quality of proteins is poor and the food composition is unreasonable.

Now there are a lot of college students, especially female students, is very interested in eating a vegetarian diet, that vegetarian diet can make the body slim and healthy, such as eating meat is not, can make people obese. In fact, the vegetarian diet has its drawbacks, it provides nutrients, especially protein, phosphorus and some inorganic salt quality, it is difficult to meet the needs of human growth and development. The advantages of meat food can precisely make up for this defect, its protein, calcium, phosphorus, fat-soluble vitamins are better than vegetarian food. Therefore, to balance the dietary structure of students, to ensure the supply of nutritional quality, we must meat and vegetables, so that the human body daily intake of sufficient nutrients.

Secondly, the situation of smoking, drinking, and surfing the Internet among male students; and the misconceptions about weight loss and beauty among female students are worrisome. As time in college, money is at the disposal of the students themselves. Therefore, in terms of money, students can most "save" down is "eat" this aspect. Male students save money for smoking, drinking, surfing the internet, etc. Female students save money for living expenses. For girls, the money they save on living expenses is used to buy clothes, go to the beauty salon, and go on a diet. There is no need to talk about the harm of smoking and drinking, as it has been publicized in various media. Surfing the Internet, on the one hand, the radiation is heavier and damages the eyes and facial panels more. On the other hand, sitting for a long time makes the blood return circle in the lower limbs and stomach blocked, affecting digestion and absorption. Long time in the computer and activities to reduce, suffering from cervical spondylosis, the chance of mouse hand greatly increased. Long hours in the Internet cafe, water supplementation is not enough, the metabolism slows down, resulting in the accumulation of toxins in the body. The production of enzymes requires a sufficient amount of protein, water, vitamins, minerals and other nutrients, and the production of digestive enzymes decreases accordingly, resulting in loss of appetite. There was one case of kidney stones in the interviewed population, where the patient spent a long time in the dormitory surfing the Internet, drinking too little water, and having an irregular lifestyle. There are many reasons for the formation of urinary stones, and experts believe that diet and nutrition are closely related to the formation of stones. Secondly, the situation of smoking, drinking and surfing the Internet in male students; and the misconceptions of weight loss and beauty in female students are worrying. As time in college, money is at the disposal of the students themselves. Therefore, in terms of money, the most important thing that students can "save" is "food". Male students save money for smoking, drinking, surfing the internet, etc. Female students save money for living expenses. For girls, the money they save on living expenses is used to buy clothes, go to the beauty salon, and go on a diet. There is no need to talk about the harm of smoking and drinking, as it has been publicized in various media. Surfing the Internet, on the one hand, the radiation is heavier, and the damage to the eyes and facial panels is heavier.

On the other hand, sitting for a long time makes the blood of the lower limbs and the stomach back to the circle blocked, affecting digestion and absorption. Prolonged time at the computer and activities are reduced, suffering from cervical spondylosis, the chances of mouse hand greatly increased. Long hours in the Internet cafe, water supplementation is not enough, the metabolism slows down, resulting in the accumulation of toxins in the body. The production of enzymes requires a sufficient amount of protein, water, vitamins, minerals and other nutrients, and the production of digestive enzymes is reduced accordingly, resulting in loss of appetite. There was one case of kidney stones in the interviewed population, where the patient spent a long time in the dormitory surfing the Internet, drinking too little water, and having an irregular lifestyle. There are many reasons for the formation of urinary stones, experts believe that diet and nutrition have a close relationship with the formation of stones.

2, measures and recommendations

2.1 Carry out nutritional health education

Through nutritional health education, students' dietary nutrition can be significantly improved. It is necessary to strengthen the education of nutritional health knowledge for college students. Make them understand nutritional hygiene. It is recommended that colleges and universities open more public **** elective courses on dietary nutrition and health, so that students can master basic nutritional knowledge, guide and help college students to establish a sense of self-care and develop good dietary habits.

2.2 Develop scientific and reasonable breakfast recipes

Domestic and international nutrition experts generally believe that breakfast is the most important meal of the day, providing energy to account for 30% of the whole day, and the quality of the whole day nutrient standards should be reached 1/3. 10 percent of the students in colleges and universities never ate breakfast, and at the same time, most of the students do not pay enough attention to the quality of the breakfast, the variety of breakfast food is arbitrary. At the same time, most students do not pay enough attention to the quality of breakfast, and the variety of breakfast food is arbitrary. Therefore, vigorously promoting nutritious breakfast has a better effect on promoting students' physical development, improving their nutritional status and improving their concentration. At the same time, a nutritionist or health care provider can provide a variety of nutritional formulas to meet the students' needs for various nutrients and change the students' poor dietary habits according to the students' characteristics.

2.3 Perfecting Dietary Structure

The principle as well as the method of rational nutrition is an important tool for people to promote their health, and its use can fully mobilize college students' enthusiasm for self-care. As long as according to their own conditions, a reasonable combination of various types of food available on the market, you can achieve the purpose of dietary balance. Good nutrition does not mean that a balanced diet can be achieved with a reasonable combination of foods available on the market. Human food is diverse. Various foods do not contain exactly the same nutrients. With the exception of breast milk, no single natural food can provide all the nutrients needed by the human body. A balanced diet must consist of a variety of foods in order to satisfy the various nutritional needs of the human body and achieve the purpose of rational nutrition and promotion of health, and thus we should advocate that college students consume a wide variety of foods. Cereals are the main source of energy and protein in our diet, and the energy needs of adolescents are large and can vary depending on the level of activity. Inadequate protein intake can affect the growth and development of adolescents.

2.4 Strengthen the management of food

Colleges and universities should strengthen the management of the student cafeteria, extend the opening hours of the cooking staff for nutritional health education, so that through the school cafeteria to provide students with hygiene and a variety of food, which is conducive to the physical and mental health of college students. College cafeterias should be equipped with high-level nutritionists and cooks, and management should be strengthened to continuously improve the nutritional level of meals and ensure the physical and mental health of college students. Looking at the nutritional status of male and female college students in colleges and universities, some nutrient intake is low, especially the quality is not high. Attention should be paid to adjusting and improving the supplementation. In particular, we should fully guarantee the supply of protein and calories for college students, and constantly increase the proportion of animal protein supply. Supply more lean meat, fish, milk, eggs and soy products, increase the supply of fresh vegetables and fruits, and ensure vitamin A and vitamin C supply. While emphasizing the nutritional hygiene of college students, it is necessary to develop good dietary hygiene habits, three meals a day at regular intervals, so that breakfast should be full, Chinese food should be eaten well, and dinner should be eaten less, and the calorie distribution of the three meals should be scientific and reasonable.

2.5 Points of Attention for Female College Students in Diet

Eat enough for lunch and dinner, and eat less snacks. Most of the snacks are high in fat and sugar and contain less protein. Too much snacking will affect the amount of food eaten during the main meal, causing an imbalance in nutrient intake and making the body prone to a lack of protein, inorganic salts and vitamins, and so on, so one should snack less. As college students study longer in the evening and sleep later, the amount of food for dinner should not be ignored.
