In all areas of society, we all often come into contact with dissertations, right? A dissertation is an essay that discusses a certain issue or researches a certain problem. So have you ever understood thesis? The following is a thesis that I have organized for you to discuss the dietary nutrition and health of college students.
Talking about college students dietary nutrition and health thesis Part 1
College students as a new generation of academic groups, the successor of the motherland, their nutritional quality of the up and down, will directly affect the future of the motherland. Cultivate college students good dietary habits, constitute a healthy body, is a necessary prerequisite for the future development of society. Therefore, attention to the health of college students has become a problem that we can not ignore. This paper will discuss the problems and countermeasures of contemporary college students' diet.
First, our college students in the nutritional status of the survey
Through the questionnaire survey of 500 college students, the results show that nearly half of the college students are malnourished or over-nutrition, the current nutrition and health of college students in the school is not optimistic. The reasons for this are analyzed as follows:
Not paying attention to balanced nutrition. Survey results show that most college students lack of understanding of nutritional knowledge, there is a phenomenon of indiscriminate eating, do not pay attention to my dietary balance, do not pay attention to scientific and nutritional, dietary arbitrariness is greater, there are some problems with the generality.
1, carbohydrate intake is obviously insufficient. Especially girls intake of calories is generally low, only about 69% of the standard calories.
2, improper distribution of calories in three meals. Many students stay up late at night, not enough sleep, in the morning it is too late to eat breakfast, and some students have developed a 10:00 a.m. recess to eat in a hurry the bad habits.
3, quality protein intake is insufficient. According to the survey results show that boys protein intake for the standard supply of 70%, 75% of girls.
4, vitamin intake is insufficient. Because our school is located in a remote area, there are very few vendors on campus, vegetables and fruits to buy to go to the farther market, part of the college students would rather not eat for this reason.
Unhealthy eating habits. The survey shows that college students are partial to food, picky eaters accounted for 42%, of which 64% of girls to snacks, vegetarian diet, boys accounted for 36%, to meat, carbohydrate-based, do not eat breakfast or breakfast to snacks instead of 32%, this is caused by malnutrition and nutritional overnutrition is an important reason, college students are in the growth of the development of the period of the peak of the heavy burden of learning in this period, the amount of activity, energy and nutrient needs are more than other adults. The demand for energy and nutrients is higher than that of other adults. The long-term diet of snacks and vegetarian food instead of staple food and monotonous food are the main causes of malnutrition among female students. Diet for a long time in favor of meat, carbohydrate food, so that the body fat, too much energy, coupled with a lack of exercise, over time will cause obesity, which is the main cause of obesity in boys. Some other girls in order to lose weight blind diet, lunch is not full, dinner is almost not eaten or fruit instead of, yogurt instead of, causing malnutrition.
The role of a balanced diet for college students
A balanced diet has a close relationship with the growth and development of college students, their learning spirit, and the treatment and prevention of diseases.
The importance of a balanced dietary structure for growth and development. The nutrition is the main material basis for the growth and development of college students, the growth and development of the organism, life activities and mental and physical labor, are dependent on the body's material metabolism, the body in the process of material metabolism must be constantly from the outside world to take a certain amount of food, a reasonable diet is the quality of college students' growth and development of the foundation. The growth and development of the human body, life activities, brain brawn labor, are dependent on the quality of the body's metabolism. The first thing you need to do is to take in a certain amount of nutritious food from the outside world in order to promote the growth and development of the body, and to make the human body full of spirit.
A balanced diet can improve the learning efficiency of college students. A balanced diet can improve the brain's mobility and improve the learning efficiency of college students.
Three, how to improve the dietary nutrition of college students
Raise awareness of the popularization of nutritional knowledge. Through a variety of effective ways to vigorously publicize the scientific and rational knowledge of nutrition, so that college students understand the composition of the adult dietary pagoda, understand their daily needs of high-quality proteins, fats, carbohydrates, vitamins, inorganic salts, water and the amount of dietary fiber, the food requirements for diversified to cereals, eat more high-quality proteins and fresh fruits and vegetables, and often eat milk, beans, or their products, eat fish, poultry, eggs, lean meat in moderation, eat less fatty meat and meat products. , less fatty meat and meat oil, less sugar and salt. Help students to establish the concept of dietary balance, understand the interconnection of various nutrients in the human body, the relationship between each other, each other's influence, and completely correct the bad eating habits of partiality, so that college students learn to understand that good eating habits are the need for health, but also civilized performance.
Adjust the dietary structure of college students. Pay attention to the art of food cooking, food rational allocation of reasonable cooking is to ensure that the quality of meals and nutritional level of one of the important links. Various foods do not contain the same nutrients, any one natural food can not completely provide all the nutrition necessary for the human body, so college students must widely eat a variety of foods, scientific distribution of nutrition and the number of food at each meal, to do a good breakfast, lunch, dinner, appropriate nutritional principles, to meet the needs of college students of the nutrients, to promote the healthy growth of college students, the staff of the cafeteria should be based on the local dietary habits, climate and geography. Cafeteria staff should also select nutritious and reasonably priced food according to local dietary habits, climatic and geographical conditions, and market conditions, etc. According to the attributes of the food, they should add pleasant color, aroma, taste and other sensory effects, and at the same time, make the food more easily digested and absorbed to improve the utilization rate of the nutrients contained in the body. The first thing you need to do is to try to save the original nutrients in the food to avoid destroying the loss.
In short, college students are now in a critical period of physical and mental development, a reasonable diet on the physical and mental development of college students play a key role. Therefore, pay attention to the dietary health of college students is the urgent work of every educator.

Preface
The word "nutrition" is derived from Latin, which means "lactation". "to lactate". Nutrition is the material basis for human beings in order to maintain life and meet the energy needs of the organism for survival, learning and work. In the world of nutrition, it is usually the whole process of ingestion, digestion, absorption and utilization of food by the human body that is referred to as nutrition. Nutrients, on the other hand, are substances that ensure the growth, development, reproduction and maintenance of a healthy life of the human body, of which the most important ones 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 a lifetime 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.
A measure of self-health
Health is not only the absence of physical disability, but also a complete physical and mental state and social adaptation. The standard of health: have plenty of energy, can comfortably take on daily life and heavy work, and do not feel overly nervous and fatigue, optimistic, positive attitude, willing to take responsibility, not picky, good rest, good sleep, resilience, adaptable to changes in the external environment, able to resist the general colds and infectious diseases, appropriate weight, body proportionality, standing head, shoulders, arm position coordination, the eyes bright, responsive, eyes and face, the eyes and face, the eyes and face, the eyes and face, the eyes and face. 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 skin is elastic. The four cornerstones of health: rational diet, moderate exercise, abstain from smoking and alcohol, and psychological balance.
(a) The main problems of diet and nutrition of our college students
Du Yumen, 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: first, the lack of nutritional knowledge, unscientific eating 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 not eating 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 (protein, fat, sugar, 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 and processing of reasonable to enhance the appetite, and diversified (color, aroma, taste, beauty are complete), 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 the total calories of the whole day, and for breakfast accounted for 30% of the total calories of the whole day. According to the recommendation of the 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 eating 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 diets are not regular, and the amount and timing of the 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, snacks is more common, the distribution of three meals is unreasonable, the distribution of calorie 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, there is the idea of losing weight, which is predominantly female.
3, a considerable part of the students, especially the lower grades of students have the habit of addiction to Internet cafes, often stay out late, so that the physical quality of the sharp decline. 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 learning, living habits also directly affect the students' dietary habits of unscientific, irregular.
4, especially serious, many students think that they are young, for the body of the temporary symptoms do not pay enough attention, but do not know that these problems accumulated to a certain extent will explode.
3 dietary structure is unreasonable
China Nutrition Society to learn from the lessons of the Western and Japanese dietary composition, in China's traditional dietary structure based on the model, the development of China's recent adult reasonable dietary composition indicators, and to the national people recommended. 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, milk 2 kg, 12 kg of vegetables, fruits 3 kg. so that the average daily intake of total energy of 10 MJ, you can achieve the 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. Female students' diet is based on vegetables, melons 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.
The role of a balanced diet for college students
The main nutrients needed by the human body are carbohydrates, proteins, fats, vitamins, inorganic salts, water, and dietary fibers, etc., which have important physiological functions for the human body. For college students, ensuring scientific nutrition and a balanced diet has the following roles.
(a) 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 heavy task, their growth and development, the effectiveness of learning, the ability to live and resistance to disease, labor effectiveness, the size of the ability to exercise, and so on, have a close relationship with the nutritional hygiene. All of these have a close relationship with nutrition and hygiene. If they are malnourished, it will not only affect their physical health, but also their study and life. Scientific studies have shown that proper improvement of nutritional status, making the diet structure as balanced as possible, may have a beneficial effect on the full play of long term memory.
(2) Strengthening the body, preventing and eliminating diseases
A balanced diet is equivalent to a kind of dietary supplement, which on the one hand replenishes the deficiency, i.e., replenishes the deficiency of the body's qi and blood; and on the other hand enhances the body's immune system and reduces the occurrence of diseases. Dietary supplements are mainly for nourishment, treatment as a supplement, it will be dietary nutrition and medication perfectly integrated, can enjoy the pleasure of food, but also up to the body, prevention of disease efficacy of the 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 have a certain role in the reduction of heart disease, diabetes and cancer help, while the intake of food rich in vitamin C, vitamin E and carotene, can make the skin aging slower, and free from the plague of age-related diseases.
(C) alleviate 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, this 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
(a) To strengthen the education of college students' knowledge of nutritional hygiene
It is recommended that our school more public **** elective courses on diet and nutrition, so that they know about nutritional hygiene, to guide and help college students to establish a sense of self-care, and to develop good . 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 college students' dietary health. 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 and existing problems in the daily life of Chinese college students, it is evident that paying attention to and improving the nutritional health of college students has an important influence on the economic, scientific and civilized development of both individuals and the country, and even the society.
Abstract This paper discusses the nutrition and health of college students in the past.Keywords: college students paper published
Human society has entered a high-speed development of the economic period, the competition in the twenty-first century, not only the competition of learning, but also the competition of talent. College students as a new generation of learning groups, the motherland's successor, their nutritional quality of up and down, will directly affect the future of the motherland. Cultivate college students good dietary habits, constitute a healthy body, is the necessary prerequisite for the future development of society. Therefore, attention to the health of college students has become a problem that we can not ignore. This paper will discuss the problems and countermeasures of contemporary college students' diet.
First, the nutritional situation of our college students
Recently, the author of my school 200 students conducted a questionnaire survey, and found that there are some bad eating habits among college students in general, such as: morning exercises, time panic, do not go to eat breakfast, some students in order to lose weight, diet, some students picky eaters, Eating, and even some students usually do not eat, wait until the weekend to eat a big meal. All kinds of factors lead to the majority of college students malnutrition. Further cause college students in the prevalence of some nutritional deficiency diseases, such as: vitamin A deficiency, protein deficiency, iron deficiency anemia, calcium deficiency and so on. According to the author's survey, the daily protein intake of most college students is only about 70% of the standardized supply. At the same time, the nutritional value of their diet is not high, a lot of students in order to save money, specializing in pasta, especially some male students, three times a day are pasta, resulting in less meat, eggs, milk, vegetable intake, nutritional mix is not reasonable. According to the determination of the hemoglobin of college students, the rate of anemia for 24% of male students, female students 41%, this data fully illustrates the serious lack of high-quality proteins and vitamin C in college students, affecting the absorption and application of iron.
The role of reasonable dietary structure on college students
Reasonable dietary structure on the growth and development of college students, learning spirit, as well as the treatment of disease, prevention has a close relationship.
1. The importance of reasonable dietary structure for growth and development. Reasonable diet is the material foundation of college students' growth and development. The growth and development of the human body, life activities, brain brawn labor, are dependent on the body's material metabolism. In the process of material metabolism in the human body, it is necessary to take a certain amount of nutritious food from the outside world from time to time in order to promote the growth and development of the body, and to fully realize the spirit of the human body. The first thing that you need to do is to get your hands on some of the most popular products in the world, and then you can get your hands on some of the most popular ones.
2. Reasonable dietary structure can improve the learning efficiency of college students. Brain tissue is the most active organ of the human body, although his weight as long as the body's overall weight of about 2%, but the brain consumes energy but accounted for the body's total energy consumption of 20%. Therefore, a reasonable dietary structure can improve the brain's activity, and improve the learning efficiency of college students.
3. The effect of sugar on the brain. Sugar can participate in a variety of cellular metabolic activities, to maintain the normal function of the nervous system, to promote protein synthesis and many other tasks, in terms of intelligence, sugar is simply the brain's only fuel, which provides energy for the brain continuously and steadily, can improve people's attention, response ability, memory and understanding of the ability to eat a little bit of sugar in the mood impulsive to play a role in improving the mood.
4. The brain's need for protein. Eating different levels of protein food has a significant impact on brain activity. Increase the protein content of food, can strengthen the cerebral cortex of excitation and inhibition, and protein in the synthetic ammonia can also eliminate the brain cells in the metabolism of ammonia toxicity, there is a role in the maintenance of the brain. Therefore, in the diet should ensure high-quality protein, such as eggs, dairy products, meat, fish and shrimp, soy products, etc., help to adhere to normal mental activity.
5. Calories. The body can produce heat energy nutrients for protein, fat and carbohydrates. Normal people weigh 60 kilograms, in the fasting, awake and quiet state, in the suitable air (18 ℃ ~ 25 ℃), 24 hours to maintain the fundamental life activities required calories about 6024.96kJ. Young students normative intake of calories, daily boys should be 10878.4kJ, girls should be 10041.6kJ. food nutrients in the calorie production: protein per gram of output 16.74kJ per gram of protein, 37.66kJ per gram of fat, and 16.74kJ per gram of carbohydrates.The main sources of calories are sugar and fat, followed by protein. Due to the college students to mental labor, is in the late adolescent development, the body is still in the development, so appetite, caloric demand, in order to ensure that college students have a vigorous spirit of learning and participation in various activities, should ensure that the intake of sufficient calories.
6. Vitamins, inorganic salts. The following table shows the daily supply of inorganic salts and vitamins for college students.
Vitamins and inorganic salts are essential for the composition of the human body, the maintenance of life, growth and development, reproduction and other functions, as well as regulating the metabolism of substances, the composition of certain coenzymes of the main components. These nutrients in the daily food content are relatively abundant, such as vegetables, milk, meat, soy products, etc., so the need to adhere to a balanced diet. Under normal circumstances, the nutritional needs of the day, should be spread evenly among the three meals. The calories taken in each meal should account for about 1/3 of the total calories of the whole day, but lunch both to supplement the morning calorie consumption, but also for the afternoon's work, learning to provide energy, can be more. Therefore, the calories of three meals a day, breakfast should account for 25% to 30%, lunch accounts for 40%, dinner accounts for 30% to 35%. So, how to arrange three meals a day? People often say, "eat early, eat full, eat less late", this health experience is reasonable. Breakfast should not only pay attention to the number, but also to examine the quality. Lunch should be appropriate to eat more, and the quality should be high. Dinner should eat less, to greasy, easy to digest as a guideline, at least two hours before going to bed to eat.
Three, college students healthy diet guidelines
(1) food variety, cereal-based;
(2) eat more vegetables, fruits and potatoes;
(3) eat dairy, beans or their products every day;
(4) often eat the right amount of fish, poultry, eggs, lean meat, less fat and meat oils
(5) food and brawn activities should be balanced, adhere to the appropriate weight;
(6) eat greasy less salt meals;
(7) such as drinking alcohol should be limited;
(8) eat clean and hygienic, do not metamorphosis of the food.
Discussion
The elements of bad dietary habits: At present, some college students have the following 9 bad dietary habits in their daily life, which bring serious impact on their health and should arouse the attention of our college students. Health science informs us that irregular eating is very easy to cause gastric disease, in which gastric ulcer is the most common, which is many college students gastrointestinal function is not good, the incidence of gastric disease is an important reason. According to medical evidence, scientific diet must follow the following guidelines: First, forbidden to eat once metamorphosed peanuts, soybeans, corn, walnuts, and a variety of dried fruits and other foods, which contain a large number of toxic aflatoxins, which are able to cause tumors in the kidneys, stomach, rectum, mammary glands and ovaries; secondly, forbidden to eat all the outdated or metamorphosis of the food; thirdly, less pickled and preserved food products; fourthly, less fried, sugary foods and may make the body thin. And may make the body thin food; Fifth, eat less fennel, pepper and other spicy spices, the excessive consumption of these spices will stimulate the gastric mucosa; Sixth, the evening meal half an hour before going to bed. Moderation of dinner is a very important health measure.
In short, college students are now in a critical period of physical and mental development, a reasonable diet on the physical and mental development of college students play a key role. Therefore, pay attention to the dietary health of college students is the urgent work of every educator.
