In all fields of society, everyone will often come into contact with papers, which are articles to discuss or study a certain problem. So, have you understood this paper? The following is my paper on college students' diet, nutrition and health for your reference, hoping to help friends in need.
On the Dietary Nutrition and Health of College Students 1 As a new generation of learning groups and successors of the motherland, their nutritional quality will directly affect the future of the motherland. Cultivating college students' good eating habits and forming a healthy body is a necessary prerequisite for the future social development. Therefore, paying attention to the health of college students has become a problem that we can't ignore. This paper will discuss the problems and countermeasures of contemporary college students' diet.
First, the nutritional status of college students.
Through the questionnaire survey of 500 college students, the results show that nearly half of them are malnourished or overnourished, and the nutritional health status of college students is not optimistic at present. The reasons are analyzed as follows:
Do not pay attention to balanced nutrition. The survey results show that most college students lack nutrition knowledge, overeat, do not pay attention to their own dietary balance, do not pay attention to scientific nutrition, eat casually, and some problems are universal.
1, carbohydrate intake is obviously insufficient. In particular, the calorie intake of girls is generally low, only about 69% of the standard calorie.
2. Improper distribution of calories in three meals. Many students have no time to eat breakfast in the morning because they stay up late at night and don't have enough sleep time. Some students have developed the bad habit of having a rest at 10: 00 in the morning and eating in a hurry.
3. Insufficient intake of high-quality protein. The results show that the intake of protein for boys is 70% of the standard supply, while that for girls is 75%.
4. Insufficient vitamin intake. Because our school is remote, there are few vendors in the school, and vegetables and fruits have to be bought in distant markets, so some college students prefer not to eat them.
Bad eating habits. The survey shows that college students are picky eaters, accounting for 42%, of which girls account for 64%, mainly snacks and vegetarianism, and boys account for 36%. 32% people skip breakfast or use snacks instead of breakfast, which is an important reason for malnutrition and overnutrition. College students are in a vigorous period of growth and development. During this period, they have a heavy learning burden, a large amount of activities, and poor energy and nutrition. Snacks and vegetarianism replace staple food in long-term diet, and the food is monotonous, which is the main reason for malnutrition of girls. Long-term preference for meat and carbohydrate foods in the diet leads to excessive body fat and energy, coupled with lack of exercise, which will lead to obesity over time, which is the main reason for boys' obesity. In order to lose weight, some girls blindly go on a diet, don't have enough for lunch, hardly eat dinner or replace it with fruit or yogurt, resulting in malnutrition.
Second, the role of a balanced diet for college students
A balanced diet is closely related to college students' growth and development, learning spirit, treatment and prevention of diseases.
The importance of balanced diet structure to growth and development. Nutrition is the most important material basis for the growth and development of college students. The growth and development of organisms, life activities, and mental and physical labor all depend on material metabolism in the body. In the process of material metabolism, the body must constantly take in a certain amount of food from the outside, and a reasonable diet is the quality basis for the growth and development of college students. The growth and development of human body, life activities and mental and physical labor all depend on the mass metabolism in the body. In the process of material metabolism of human body, in order to promote the growth and development of the body and fully enrich people's spirit, a certain amount of nutritious food must be ingested from time to time.
A balanced diet structure can improve the learning efficiency of college students. Reasonable nutrition plays an important role in promoting college students' health and study. Therefore, a reasonable diet structure is necessary for the healthy growth of college students, which can improve the activity of the brain and the learning efficiency of college students.
Third, how to improve the dietary nutrition of college students.
Raise awareness and popularize nutrition knowledge. Vigorously promote scientific and reasonable nutrition knowledge through various effective ways, so that college students can understand the composition of adult dietary pagoda and their daily requirements for high-quality protein, fat, carbohydrates, vitamins, inorganic salts, water and dietary fiber. Food should be diversified, with cereals as the main food. Eat more high-quality protein and fresh vegetables and fruits, often eat milk, beans or their products, eat fish, poultry, eggs and lean meat in moderation, and eat less fat and meat fat. Help students to establish the concept of dietary balance, understand the relationship between various nutrients in the human body, completely correct the bad eating habits of partial eclipse, and let college students understand that good eating habits are the need of health and the embodiment of civilization.
Adjust the dietary structure of college students. Paying attention to the art of food cooking and reasonable food distribution and cooking are one of the important links to ensure the quality and nutritional level of food. The nutrients contained in various foods are not exactly the same, and no natural food can completely provide all the nutrients needed by the human body. Therefore, college students must eat a wide range of foods, scientifically distribute the nutrition and food quantity of each meal, and follow the principle of eating well at breakfast, eating well at lunch and having proper nutrition at dinner, so as to meet the nutrition required by college students and promote their healthy growth. Canteen staff should also choose foods with rich nutrition and reasonable prices according to local eating habits, climatic and geographical conditions and market conditions, and increase the pleasant sensory effects such as color, fragrance and taste according to the attributes of the foods, at the same time, make the foods easier to digest and absorb, and improve the utilization rate of nutrients contained in the human body. Try to keep the original nutrients in food to avoid damage and loss.
In short, college students are currently in a critical period of physical and mental development, and a reasonable diet plays a key role in their physical and mental development. Therefore, it is urgent for every educator to pay attention to the dietary health of college students.
On Dietary Nutrition and Health of College Students 2 Abstracts
College life is an important stage of learning knowledge and growing up, and it is also an important stage of forming good eating habits. It is of great significance to master certain nutrition knowledge and form good eating habits at this stage to promote growth and ensure good health. Especially for contemporary college students, the mission entrusted to us by the times requires us to have a healthy body and be full of vigor and vitality of warm-blooded young people in order to become the pillars of the country. Then, paying attention to ourselves and health has become a problem that we can't ignore. This paper comprehensively discusses the current college students' dietary nutrition from three aspects: the general situation of college students' dietary nutrition, the role of college students' balanced diet and the countermeasures to improve their dietary quality, in order to enhance their awareness of balanced diet nutrition.
key word
Dietary nutrition; Health; General situation; measure
order
The word "nutrition" comes from Latin, which means "breastfeeding". Nutrition is the material basis for human beings to maintain life and meet the energy needs of survival, study and work. In the field of nutrition, the whole process of food intake, digestion, absorption and utilization is usually called nutrition. Nutrients refer to substances that ensure human growth, development, reproduction and maintain a healthy life, among which the most important nutrients are carbohydrates, protein, fat, water, minerals and vitamins. College students are a special youth group, which is in the middle and late stage of growth and development. They are lively and active, exercise a lot, plus heavy mental work and intense study, which is the period when they need nutrition most in their lives. But at present, Chinese college students know little about the source of nutrients and food classification, and they don't know how to mix nutrients. There are many nutritional problems, which will affect the growth and study of college students.
First, the standard of measuring self-health
Health is not only a physical disability, but also a complete physical, psychological and social adaptability. Health standard: energetic, able to undertake daily life and heavy work calmly, not feeling too nervous and tired, optimistic and positive, willing to take responsibility, not picky, good at rest, good at sleep, strong adaptability, able to adapt to various changes in the external environment, able to resist common colds and infectious diseases, moderate weight, well-proportioned figure, coordinated head, shoulders and arms when standing, bright eyes and quick response. The four cornerstones of health: reasonable diet, moderate exercise, smoking cessation and alcohol restriction, and psychological balance.
(A) the main problems in the dietary nutrition of college students in our school
Du, president of the Student Nutrition and Health Promotion Association, pointed out that there are three main problems in the nutrition and health status of students in China: First, lack of nutrition knowledge and unscientific eating habits. Second, the diet structure is unreasonable. The energy supply ratio of cereals and protein is low, while that of urban school-age children and adolescents is high. Insufficient nutrition intake. There is a general lack of micronutrients such as calcium, iron, zinc and vitamin A. Third, lack of physical activity. Bad lifestyles, such as skipping breakfast, eating out, drinking and smoking, have increasingly prominent effects on health.
1 Lack of nutrition knowledge.
With the rapid development of national economy and the continuous improvement of people's living standards, more and more people begin to pay attention to diet and nutrition. With the popularization of nutrition science knowledge and the publicity and education of nutrition and hygiene, people have a further understanding of balanced diet nutrition and hygiene. First of all, the diet should contain all the necessary nutrients (protein, fat, sugar, vitamins, inorganic salts and water). Secondly, food intake should be conducive to digestion, absorption and utilization, fresh and pollution-free, and reasonable production and processing can stimulate appetite and diversify (color, fragrance, taste and beauty). At the same time, the calories of three meals a day should be reasonably distributed. According to the recommendation of China Nutrition Society, breakfast takes up a whole day. College students in our school generally lack nutrition knowledge and the malnutrition rate is high. College students lack nutrition knowledge, and their performances are different among students of different majors. Generally speaking, girls have better nutrition knowledge than boys.
2 Eating habits are unscientific
After entering the university, the daily diet of college students is controlled by the students themselves. Many students' living habits are extremely unscientific, mainly manifested in:
1. The daily diet of most college students is irregular, and the amount and time of three meals a day are often irregular. Most students don't have the habit of eating three meals regularly, and most of them don't eat in the school cafeteria. Many college students don't pay attention to breakfast, but the phenomenon of eating supper and snacks is common, the distribution of three meals is unreasonable, and the calorie intake of each meal is uneven.
2. After entering the university, many college students like to eat cold drinks, and sugar addiction phenomenon is obvious. The sugar intake of male and female college students generally greatly exceeds the standard supply, which makes them gain weight and have the idea of losing weight, and most of them are girls.
A considerable number of students, especially juniors, have the habit of indulging in internet cafes, often staying up late outside, and their physical fitness has dropped sharply. I often skip classes, even if I attend classes, I am mentally exhausted and can't concentrate on listening. College students often drink drinks instead of milk and fruit, and often overeat and so on. The lack of good study and living habits also directly affects the unscientific and irregular eating habits of students.
What is particularly serious is that many students think they are young and don't pay enough attention to their temporary discomfort. I don't know if these problems will break out when they accumulate to a certain extent.
3 unreasonable diet structure
On the basis of China's traditional dietary pattern, the Nutrition Society of China recently formulated a reasonable dietary composition index for adults in China and recommended it to the people all over the country. The dietary composition index is as follows: adults consume grain 14 kg, potatoes 3kg, beans 1 kg, meat 1 5 kg, fish 500 g, vegetable oil 250g, eggs 500 g, milk 2 kg, vegetables 12 kg and fruit 3 kg per month. In this way, the average daily total energy intake is 10 MJ, which can achieve the basic balance of dietary nutrition. At present, the diet of college boys is mainly cereals and their products, followed by vegetables, melons and eggplant, and the rest are livestock meat, beans and their products. The diet of girls is mainly vegetables, melons, eggplant, cereals and their products, followed by livestock meat, beans and their products. The intake of vegetables, fruits, fish, milk and eggs for boys and girls does not meet the requirements, indicating that the dietary composition is not reasonable enough. The student canteen should increase the supply of these foods to meet the requirements of students' reasonable dietary structure.
Second, the role of college students' balanced diet
The main nutrients needed by human body are carbohydrates, protein, fat, vitamins, inorganic salts, water and dietary fiber, which have important physiological functions for human body. For college students, ensuring scientific nutrition and balanced diet has the following functions.
(A) to supplement physical strength and enhance memory
College students are a special group. They are in adolescence, with vigorous metabolism, lively activities and a lot of exercise. At the same time, their growth and development, learning efficiency, living ability and disease resistance, labor efficiency and sports ability are closely related to nutrition and health. If you are malnourished, it will not only affect your health, but also your study and life. Scientific research shows that properly improving the nutritional status and making the diet structure as balanced as possible may have a beneficial impact on the full play of long-term memory.
(b) Physical health, disease prevention and treatment.
Diet balance is equivalent to a kind of food supplement, on the one hand, it supplements deficiency, that is, it supplements the deficiency of qi and blood in the body; On the other hand, it can enhance the immune ability of the body and reduce the occurrence of diseases. Food supplement is mainly nourishing, supplemented by treatment. It perfectly combines dietary nutrition and drug therapy, which can not only enjoy delicious food, but also achieve the effects of strengthening the body and preventing and treating diseases. The most important thing is that food tonic is better than medicine tonic, both ancient and modern. Through reasonable nutrition and physical exercise, it helps to reduce heart disease, diabetes and cancer. At the same time, eating foods rich in vitamin C, vitamin E and carotene can slow down skin aging and avoid age-related diseases.
(3) Relieve emotions and regulate emotions
College students are often not calm, impulsive, angry, and bored with some boring courses, which is not good for study or health. There are some nutrients in the food that the human body ingests that can improve people's mood and make people relaxed and happy. Such as spinach rich in magnesium, can relax people's body and mind; Eggs, rich in choline, help to improve memory and attention; Melon seeds help to calm down. Let college students know this knowledge, which has a certain effect on relieving mood and regulating mood.
Third, measures to improve the quality of college students' diet
(A) to strengthen the education of nutrition and health knowledge of college students.
It is suggested that our school should offer more elective courses in diet and nutrition, so that they can understand nutrition and hygiene, guide and help college students to establish self-care awareness and develop good eating habits. At the same time, the canteen should be equipped with high-level nutritionists and chefs, strengthen management, continuously improve the nutritional level of the diet, and ensure the healthy diet of college students. The knowledge of diet and health should be added to the teaching in physical education class in time and included in the physical education examination, accounting for a certain proportion. Through these measures, the purpose is to make students pay attention to the importance of eating habits to physical and mental health. Obviously, strengthening nutrition education, popularizing nutrition knowledge and forming scientific and healthy eating habits can reduce the occurrence of various nutritional diseases and enhance the physical quality of the people. Combined with the current situation and existing problems in the daily life of college students in China, we can see that paying attention to and improving the nutritional health of college students has an important impact on the economic, technological and civilized development of individuals, countries and even society.
On college students' diet, nutrition and health Abstract 4 This paper discusses the nutrition and health of college students at ordinary times.
Keywords: publication of college students' papers
Human society has entered a period of rapid economic development. The competition in 2 1 century is not only the competition of knowledge, but also the competition of talents. As a new generation of knowledge groups and successors of the motherland, the nutritional quality of college students will directly affect the future of the motherland. Cultivating college students' good eating habits and forming a healthy body is a necessary prerequisite for the future social development. Therefore, paying attention to the health of college students has become a problem that we can't ignore. This paper will discuss the problems and countermeasures of contemporary college students' diet.
First, the nutritional status of college students in our school
Recently, the author conducted a questionnaire survey on 200 students in our school, and found that there are some unhealthy eating habits among college students, such as: after doing morning exercises, time is flustered, some students go on a diet to lose weight, some students are picky eaters, and some even skip meals until weekends. Various factors lead to malnutrition in most college students. In addition, some nutritional deficiency diseases are common among college students, such as vitamin A deficiency, protein deficiency, iron deficiency anemia and calcium deficiency. According to the author's investigation, the daily intake of protein by most college students is only about 70% of the standard supply. At the same time, the nutritional value of their diet is not high. Many students specially eat pasta to save money, especially some male students, who eat pasta three times a day, resulting in less intake of meat, eggs, milk and vegetables and unreasonable nutrition mix. According to the determination of hemoglobin of college students, the anemia rate of boys is 24%, and that of girls is 465,438+0%. This data fully shows that there is a serious shortage of high-quality protein and vitamin C among college students, which affects the absorption and application of iron.
Second, the role of a reasonable dietary structure for college students
Reasonable dietary structure is closely related to college students' growth and development, learning spirit, treatment and prevention of diseases.
1. The importance of a reasonable dietary structure to growth and development. Reasonable diet is the material basis for the growth and development of college students. The growth and development of human body, life activities and mental work all depend on the metabolism of substances in the body. In the process of human metabolism, in order to promote the growth and development of the body and fully enrich the human spirit, it is necessary to take in a certain amount of nutritious food from time to time. Enhance the body's sports ability and improve learning efficiency.
2. Reasonable dietary structure can improve the learning efficiency of college students. Brain tissue is the most active organ in human body. Although its weight only accounts for about 2% of the total body weight, the energy consumed by the brain accounts for 20% of the total body energy. Therefore, a reasonable diet structure can improve the activity of the brain and the learning efficiency of college students.
3. The effect of sugar on the brain. Sugar can participate in various metabolic activities of cells, maintain the normal function of nervous system, and promote the synthesis of protein. As far as intelligence is concerned, sugar is simply the only fuel for the brain. It can provide energy to the brain continuously and steadily, and can improve people's attention, reaction ability, memory and understanding ability. Eating some sugar properly when you are impulsive can improve your mood.
4. The brain's demand for protein. Eating different levels of protein food has a significant effect on brain activity. Increasing the content of protein in food can strengthen the excitement and inhibition of cerebral cortex, and the synthetic acid in protein can also eliminate the toxicity of ammonia produced by brain cells in metabolism, which has the function of maintaining the brain. Therefore, we should ensure high-quality protein in our diet, such as eggs, dairy products, meat, fish and shrimp, bean products and so on. , help to adhere to normal ideological activities.
5. heat. The nutrients that can generate heat energy in human body are protein, fat and carbohydrate. When a normal person weighs 60 kg, in an empty stomach, awake and quiet state, in a suitable air (18℃ ~ 25℃), the heat required to maintain basic life activities for 24 hours is about 6024.96kJ, and young students should adjust their intake of heat energy. The daily intake is 10878.4kJ for boys and/kloc for girls. Heat production of nutrients in food: protein produces heat per gram 16.74kJ, fat 37.66kJ and carbohydrate 16.74kJ. The main sources of calories are sugar and fat, followed by protein. Because college students are mainly engaged in mental work, they are in the late stage of puberty and their bodies are still growing and developing, so they have a strong appetite and a great demand for calories. In order to ensure that college students have a strong spirit to study and participate in various activities, it is necessary to ensure that they consume enough calories.
6. Vitamins and inorganic salts. The following table is the daily supply standard of inorganic salts and vitamins for college students.
Vitamins and inorganic salts are essential substances for human body to maintain life, growth, reproduction and other functions, and are also the main components for regulating substance metabolism and forming some coenzymes. These nutrients are abundant in daily food, such as vegetables, milk, meat and bean products. So stick to a balanced diet. Under normal circumstances, the nutrients needed for a day should be shared equally among three meals. The calorie intake of each meal should account for about 1/3 of the total calories in the whole day, but lunch should not only supplement the calorie intake in the morning, but also provide energy for work and study in the afternoon, which can be more. Therefore, the calories of three meals a day should be 25% ~ 30% for breakfast, 40% for lunch and 30% ~ 35% for dinner. So, how to arrange three meals a day? People often say that "eat well early, eat well at noon and eat less at night", and this health experience is reasonable. Breakfast should pay attention not only to quantity, but also to quality. Eat a good lunch with high quality. Eat less dinner, greasy and easy to digest, and eat at least two hours before going to bed.
Third, the standard of healthy diet for college students.
(1) There are various foods, mainly cereals;
(2) Eat more vegetables, fruits and potatoes;
(3) Eat milk, beans or their products every day;
(4) Eat proper amount of fish, poultry, eggs and lean meat, and eat less fat and meat oil;
(5) Food intake and physical activity should be balanced, and should be adapted to body weight;
(6) Eat a greasy and salty diet;
(7) if you drink alcohol, you should limit it;
(8) Eat clean, hygienic and non-perishable food.
Four. discuss
Elements of developing bad eating habits: At present, there are nine kinds of bad eating habits in the daily life of some universities, which have a serious impact on health and should be highly valued by our college students. Health science tells us that irregular diet is easy to cause stomach diseases, among which gastric ulcer is the most common, which is also an important reason for many college students' poor gastrointestinal function and high incidence of stomach diseases. According to medical evidence, scientific diet must follow the following standards: First, it is forbidden to eat peanuts, soybeans, corn, walnuts and all kinds of dried fruits, which contain a lot of toxic aflatoxins, which can cause tumors in kidneys, stomachs, rectum, breast and ovaries; Second, it is forbidden to eat all expired or deteriorated food; Third, eat less pickled food; Fourth, eat less fried foods with high sugar content, which may make your body thinner; Fifth, eat less spicy condiments such as fennel and pepper. Excessive consumption of these condiments will stimulate the gastric mucosa; Sixth, go to bed after adding meals for half an hour at night. Skipping dinner is a very important health measure.
In short, college students are currently in a critical period of physical and mental development, and a reasonable diet plays a key role in their physical and mental development. Therefore, it is urgent for every educator to pay attention to the dietary health of college students.
