On the Significance of Balanced Diet
Graduation thesis can only have one theme (not a few works pieced together), which should be specific to the grassroots level of the problem (that is, the problem can hardly be subdivided into lower-level sub-problems), not the field to which the problem belongs, let alone the subject where the problem lies, in other words, the research topic should not be too big. Because of the wide range of issues involved, it is difficult to study the master's degree thesis thoroughly. Usually, the master's degree thesis should focus on a specific problem in a certain subject field and draw valuable research conclusions.
(2) How to write the title
The topic of graduation thesis should reflect the main content of the thesis work concisely, and should not be general. Because others want to search your paper through the keywords in the title of your paper, it is very important to use accurate language. The title of the paper should be an accurate and specific description of the research object, which generally reflects the research conclusion to some extent. Therefore, the title of our paper should not only tell readers what problems this paper has studied, but also tell readers the conclusions drawn from this study.
(C) the writing of the abstract
The abstract of graduation thesis is a high summary of the research content of the thesis, and others will search the master's degree thesis according to the abstract, so the abstract should include: an explanation of the problem and research purpose, a brief introduction of the methods and research process used, a brief summary of the research conclusion and so on. It should be independent and self-evident, and it should be a complete paper.
(D) Introduction writing
The introduction of a graduation thesis contains the following parts: 1, question; 2. The background and significance of the topic; 3. Literature review; 4. Research methods; 5. The structure of the paper.
Problem statement: explain clearly what the problem is.
Background and significance of topic selection: explain why this topic is chosen for research, that is, explain the contribution of this research to the development of disciplines and the theoretical and practical significance to the national economy and people's livelihood.
Literature review: make a comprehensive review of the literature within the scope of this research topic, and at the same time, have "comments", point out the shortcomings of existing research results, and express your own ideas for improvement.
Research methods: Explain the scientific research methods used in the paper.
Paper structure arrangement: Introduce the writing structure arrangement of this paper.
"What has been said in the introduction of the second chapter, the third chapter and the literature review part is not repeated here.
(5) Concluding words.
The conclusion is to refine and summarize the main research results and arguments of the paper, which should be accurate, concise, complete and organized, so that people can fully understand the significance, purpose and work content of the paper after reading it. This paper mainly expounds the position, function and significance of his creative work and research achievements in this academic field. At the same time, we should strictly distinguish our own achievements from those of our tutors and others.
Question 2: What a coincidence! This 5000-word paper on how to achieve a balanced diet. I have a similar one. Do you want it? Usually, the conclusion of the paper may not be limited to the memory of existing literature, because in this case, in order to make up for the lack of literature in empirical research, the paper needs to reach a higher level of creative consideration. Therefore, literature review is usually only (once again) suitable for excellent students or experienced researchers to challenge.
Question 3: Seeking a paper on balanced diet and healthy balanced diet means establishing a balanced relationship between dietary nutrition supply and physiological needs in four aspects at the same time, namely, amino acid balance, calorie nutrition balance, acid-base balance and various nutrient intake balance, which are not lacking, not biased, not excessive and chaotic. Only in this way can the digestion, absorption and utilization of nutrients be facilitated. If the relationship is unbalanced, that is, the diet does not meet the physiological needs of the human body, it will have a negative impact on human health, and even lead to some nutritional diseases or chronic diseases.
(1) amino acid balance
The nutritional value of food protein depends largely on the quantity and proportion of eight essential amino acids contained in food. Only when the quantity and proportion are close to the needs of human body can human tissue protein be synthesized. Otherwise, it will affect the utilization of protein in food. The World Health Organization put forward the proportion of eight essential amino acids needed by human body. The closer the ratio, the higher the physiological value. When the physiological value approaches 100, 100% is absorbed, which is called total amino acid balance. A protein that can achieve a complete balance of amino acids is called a complete protein. Using this standard, protein of various foods can be scored for amino acids. The amino acid ratio of eggs and human milk is very close to that of human body, which can be called food with balanced amino acids. The amino acid composition of most foods is unbalanced, so the nutritional value of protein is affected. For example, too high leucine in corn affects the utilization of isoleucine, and too high arginine in millet affects the utilization of lysine. Therefore, plant-based diet should pay attention to the reasonable collocation of food and correct the imbalance of amino acid composition. If corn and beans are mixed to make soybean corn flour and soybean millet flour, the utilization rate and nutritional value of protein can be improved.
Protein amino acid composition score of food.
Amino acid composition fraction of food
Ren nai 100
Eggs 100
Milk 95
Soybean 74
Rice 67
Peanut 65
Xiaomi 63
Wheat 53
Sesame 50
(2) Heat and nutrition constitute a balance.
Carbohydrate, fat and protein can provide calories to the body, so they are called calorie nutrients. The key to a balanced diet depends not only on the intake of these three nutrients, but also on the balance of their proportions. It is generally believed that 60-70% of human thermal energy comes from carbohydrates, 10- 15% from protein and 20-25% from fat. According to this composition ratio, and considering the difference of energy produced by different nutrients (1g protein or sugar can produce 4 kilocalories, 1g fat can produce 9 kilocalories), the intake ratio of the three major thermal nutrients in food is: carbohydrate: protein: fat = 6: 1:0.7.
When dietary fat and calories are provided too high, it will cause obesity, hyperlipidemia and heart disease. When the heat supply of protein is too high, it will affect the normal function of protein, cause protein consumption and affect the nitrogen balance in the body. On the contrary, when the supply of carbohydrates and fats is insufficient, the protection of protein will be weakened. The three affect each other, and once there is imbalance, it will affect the health of the body.
In addition, we should pay attention to the reasonable distribution of calories for three meals a day, with breakfast accounting for 30%, lunch accounting for 40% and dinner accounting for 30%.
(3) the balance between the intake of various nutrients
There is a complex relationship between various nutrients, and the demand for nutrients is different in different physiological States and different activities. Therefore, the Nutrition Society of China formulated the daily supply of various nutrients. In a certain period of time, the errors of various nutrients in our diet remain within the range of 10% of the standard supply. This mutual ratio can be called the basic balance between nutrients.
According to the "pagoda of balanced diet", we know that each person should consume (calculated by raw food) 300-500g of grain, 400-500g of vegetables and fruits, and animal foods such as fish, poultry, meat and eggs 100-200g (50g of fish and shrimp, 50-600g of poultry) every day.
(4) Acid-base balance
Under normal circumstances, due to its own buffering effect, the p H value of human blood remains between 7.3 and 7.4. Eating proper amount of acidic food and alkaline food will maintain the acid-base balance of body fluids, but if the food is not properly matched, it will cause physiological acid-base imbalance.
Common acidic foods are: egg yolk, rice, chicken, eel, flour, carp, pork, beef, dried squid, beer, flowers ... >>
Question 4: Due to the importance of reasonable nutrition and balanced diet to human health, the wind of "detoxification" prevails. There are at least ten books on detoxification in bookstores, and there are more and more "detoxification" in newspapers and online. In fact, when the wind of "detoxification" started, a few people called themselves "nutritionists" and said "detoxification" without medical education or formal nutrition education. In order to improve the ratings and attract the audience's attention, some media added fuel to the fire, giving these "alternative" people the titles of "internationally renowned experts" and "doctors in nutrition". People who don't know what to do think that the real experts have come and brought them the gospel. Thus, "detoxification" is health preservation, and "detoxification" is health care. Everyone has "poison", and "detoxification" seems to be a panacea for health. At present, some Chinese and western medicine experts who have received formal medical education have also participated in the promotion of "detoxification", which makes me puzzled. In April, I had the honor to participate in the debate on "drug rehabilitation" in the program "Chen Rong Blog" on the news and entertainment channel of Shanghai TV. Recently, I read 10 many books about "detoxification" and browsed thousands of messages online, which was quite touching. The direct feeling is that the wind of "detoxification" disturbs people's audio and video. In the sound of "detoxification", the appeal of "reasonable nutrition, balanced diet and health promotion" was drowned out.
In fact, from a health care product manufacturer's proposal to eliminate "body waste" in those years to the rampant "poison" and "poison" today, the slogan "Did you detoxify today" became more and more popular until it was alarmist and harmful to the public. What does "poison" mean? In a word, the explanation of endotoxin in human body by traditional Chinese and western medicine is the metabolite in human body. Today should also include: exogenous toxins, that is, bacteria, viruses and other microorganisms that invade the human body; Pesticide residues on fruits and vegetables and environmental pollution in cannibals lead to excessive levels of heavy metals in human bodies. In addition, there are psychotoxins, which may cause the increase and accumulation of metabolites in the body because of the great pressure of modern people's life, thus causing harm. Among them, the most important is the human body's own metabolites, especially ammonia and nitrogen-containing compounds produced by protein's metabolism, such as creatinine, urea nitrogen, uric acid, etc.
So, what is detoxification? Most of the toxins in the human body come from the body's own metabolism, producing all kinds of waste that the human body does not need. Detoxification is to excrete these wastes, for example, the wastes produced by metabolism in the body are discharged through feces; Urea, uric acid and creatinine are excreted through the kidney in the form of urine; The skin excretes some toxins and excess water through sweating; In addition, vomiting, exhaled breath, saliva secretion, etc. Can expel toxins. The human body itself has a strong ability to "detoxify", and defecation, urination and sweating are all "detoxification". In most cases, as long as the human body functions normally, it can completely rely on its own "detoxification" function and basically excrete toxins without external force. If you really need to "detoxify" through external forces, you must find out where the "poison" is, and then carry out targeted "detoxification" under the guidance of doctors according to your own specific situation and do what you can.
The human body can detoxify itself, and the so-called exogenous detoxification is not suitable for everyone. For example, "intestine washing" and detoxification have certain therapeutic and health care effects on constipation, colitis, abdominal distension, flatulence and acute fecal obstruction. However, if the large intestine is cleaned for a long time, the nutrients will be washed away with the cleaning, so that the nutrients cannot be well absorbed. Moreover, the defecation function of the large intestine may become dependent on manual flushing after repeated "intestinal lavage and detoxification", and the consequences are not optimistic; Once the ecological balance of normal intestinal flora is destroyed, it will become a new health hazard. In addition, people with severe heart disease, high blood pressure, perianal diseases and anemia, people before pregnancy and those who have just had surgery are not suitable for intestinal lavage. For example, taking medicine to relieve constipation and "detoxifying" is not a radical cure. These drugs contain rhubarb more or less, and rhubarb contains a lot of tannins. Small dose not only has no purgative effect, but also has astringent effect.
Experts believe that rhubarb is mainly used for relieving inflammation and relaxing bowels, but it must not be taken for a long time. Like drugs, they are "addictive" and have a certain degree of dependence. Once the drug is stopped, secondary constipation will occur. In addition, long-term use of rhubarb will inhibit autoimmune. Some people eat rhubarb and have side effects, such as abdominal pain and mild nausea. If you rely on purgation for a long time, it may affect the absorption of certain nutrients by the human body over time, resulting in adverse consequences such as anemia.

Question 5: The importance of reasonable nutrition and balanced diet to human health. Reasonable nutrition and a balanced diet are very important for human health. Unbalanced nutrition makes people's bodies prone to problems, so diseases arise.
Question 6: Write a short essay of at least 800 words on the theme of balanced diet. Write it yourself, and don't copy it online. After answering, you will be awarded an extra 20 100 points. Life is short. Obviously, health is everything to people. Some people say that health is 1, and wealth, career and love are all zeros behind this 1. Without 1, no amount of zeros can achieve life. Therefore, scientific diet and healthy life have become an important topic in today's society. We are in an important period of growth and development. From a small point of view, scientific diet is related to the healthy growth of all of us and the happiness of our families. We can't be the "strawberry family" in the workplace ―― those who only have a shiny appearance, but the texture is soft and weak, and the physical and psychological conditions are not able to withstand pressure; Generally speaking, we are the main force in the future social construction, and scientific diet is related to the improvement of the overall level of national quality in the future, which is reflected in the comprehensive national strength.
China's culture is extensive and profound, with a cooking culture of "five grains for nourishment"; There is a dietotherapy culture of "medicine and food are homologous"; There are also pasta culture, rice culture, tofu culture, porridge culture, tea culture, wine culture and so on. "People take food as the sky, and food is safety first." All of us should pay attention to scientific diet, eat well, eat to support people, and not eat to harm people.
But we can see that many students drink carbonated drinks before and after meals, regardless of spring, summer, autumn and winter. Every time I eat, I can see many people making instant noodles, and the aroma is overflowing. There are also some students who use styrofoam to buy takeout from outside vendors. On the roadside outside the school gate, the dusty roadside, eating roadside barbecue with relish. Go to the store and buy one or two packets of fragrant snacks with 0.5 yuan or 1 yuan. In the last five seconds after the dormitory closed in the morning, I rushed out of the dormitory and didn't eat breakfast. After two classes, I flocked to the supermarket to eat snacks. This is the behavior of "eating and hurting people".
Health is the basic right of human beings and one of the most precious wealth in life. Health is the basis of quality of life; Health is an important aspect of human self-awakening; Health is the best state of life, with rich and profound connotations. Each of us has different living habits. A healthy lifestyle is conducive to preventing diseases and prolonging life. However, many people don't know how to cherish their health, and they don't take full responsibility for the health of society, families and individuals. On the contrary, they indulge in bad life and behavior, which damages their health. To this end, the World Health Organization proposes and promotes a healthy lifestyle to the whole world, which are the four cornerstones of health: reasonable diet, moderate exercise, smoking cessation and alcohol restriction, and psychological balance. Experts have come up with such a formula: health = (emotional stability+moderate exercise+reasonable diet)/(laziness+smoking+alcohol addiction). If these requirements are fulfilled, health will naturally be less difficult.
Let "scientific diet and healthy life" be deeply rooted in people's hearts, and change from thought to behavior. Only by forming * * * knowledge and public opinion can such a warm and upward atmosphere of "scientific diet and healthy life" pervade the campus. Control money, you can get wealth; You can get healthy by controlling your diet; Control your emotions, you can get happiness, learn to control, and you can get more!
As a unit of catering workers, we often encounter the problem of what to eat healthier, so what should we eat and how to eat it? There is a food proportion relationship. That is, by establishing a balanced relationship between human physiological needs and dietary nutrient supply, a balanced diet is formed.
First, a balanced diet and scientific dining are the foundation.
With the improvement of living standards, the so-called "four highs" patients such as hypertension, hyperlipidemia, hyperglycemia and high blood viscosity in cities have shown a sharp upward trend in recent years, and they are getting younger and younger. A common symptom of China's "Four Highs" is that weight gain leads to obesity. At present, how to arrange three meals a day scientifically and reasonably has become a very important topic for urban office workers.
1, Breakfast: Give you a good start to the day.
Most people know the importance of breakfast to health, but the pace of life and work of modern urbanites is accelerating, and breakfast is easily ignored by some office workers. Especially for some young people, the importance attached to breakfast is far from enough. Because most of the day's work and study are concentrated in the morning, it takes a lot of mental and physical energy, so breakfast should be placed in a more important position in the lifestyle.
Under normal circumstances, office workers rely on breakfast to provide enough calories and nutrition to complete the work from morning to noon for three or four hours. If you don't eat breakfast for a short time, you can't see the impact on your health. If you start your morning work and study on an empty stomach for a long time, it will be harmful to your health.
So how should I eat breakfast? Despite people's age and physical condition ...
Question 7: Health and longevity of diet and nutrition is the eternal theme of human beings. For thousands of years, we have asked what health is, and most people will say without thinking: "Health means no disease". However, the definition of "health" given by the World Health Organization (WHO) is that "health means that a person is in a perfect state of physical, psychological and social adaptation, not just that he is not sick or weak". Just two sentences show us a brand-new concept of health. When we understand the new concept of health, we should also know the relationship between our life span and diseases.
So how old should a person's physiological life span be? According to biological principles, the life span of mammals is 5-6 times that of their growing period. The growth period of a person is calculated by the time when the last tooth comes out (20-25 years old), so the shortest life span of a person is 100 years old and the longest is 150 years old. It is recognized that the normal life span of a person is 120 years old. Then why don't most people live to be 120 years old? This is determined by the fact that one cannot control the speed of the aging process and that one can control the speed of the aging process through self-discipline, health preservation and health care. The World Health Organization recently suggested that everyone's life span depends largely on how they control it. The genetic factor is only 15%, and the social factor is only 10%. Therefore, if people know how to cherish and maintain themselves, they can live a long and healthy life.
What is the meaning of nutrition? "Camp" means seeking, "raising" means keeping in good health, and together they mean seeking in good health. Specifically, nutrition is the process in which living beings continuously ingest necessary substances from the outside to maintain their life activities. For people, nutrition is the whole process of taking food from the outside, digesting and utilizing the substances needed by the body in food to maintain life activities. These substances needed to maintain the normal growth, development and metabolism of the body are called "nutrients". Melissa Zhou: Don't copy what we know at present. There are 42 kinds of nutrients needed by human body, which can be divided into 6 categories, namely protein, fat, carbohydrate, minerals, vitamins and water. In recent years, some scholars believe that dietary fiber is also a nutrient.
Nutrients have different functions in the human body. It can be roughly divided into three aspects.
1. Provide energy for life activities and maintain body temperature.
2. The theory of nutrition formation and repair does not need body tissue.
3. As a regulating substance, just like the lubricating oil in the machine, it maintains various normal life activities of the body.
At present, human diseases related to nutrition and health in the world are concentrated in two aspects. One is the lack of nutrition caused by insufficient nutrient intake or poor utilization, mainly micronutrients (including trace mineral elements and vitamins). At present, about 2 billion people in the world are in a state of micronutrient deficiency, accounting for about 1/3 of the world population. Don't copy our teacher Melissa Zhou's paper. Followed by various chronic non-communicable diseases related to excessive and/or unbalanced nutrient intake. International authoritative experts believe that about 1/3 of cancers are related to diet. Chronic diseases such as cardiovascular and cerebrovascular diseases and diabetes are closely related to dietary nutrition.
1, protein
Protein is the basic component of all living cells. It consists of 20 basic amino acids, 9 of which cannot be synthesized in human body and must be obtained from food. They are the basic units of protein. The human body is composed of countless cells, of which protein is the main part. It is not only the main component of the human body, but also the substance that constitutes various important life activities in the human body. Therefore, there are thousands of protein in human body, including countless enzymes that human beings depend on for survival, various hormones that act on human metabolism, various immune substances that resist diseases, carriers of various micronutrients, and neurotransmitters that regulate normal osmotic pressure and various body fluids.
Lack of protein can be fatal. If protein is lost by more than 20%, life activities will be forced to stop, which can be seen in patients with cachexia who have been ill for a long time. The common symptoms of protein deficiency are decreased metabolic rate, fragile life, easy to get sick, and the long-term damage to organs is certain. The lack of protein is often accompanied by the lack of energy, such as growth retardation, weight loss, apathy, irritability, anemia, emaciation or edema, susceptibility to infection and secondary diseases.
2, vitamins
Vitamins are a necessity to maintain human life. ..................................................................................................................................................................... & gt
Question 8: Do you know the meaning of a reasonable diet? The relationship between diet and health Diet (also called "diet") refers to the food and drinks we usually eat. All food comes from plants and animals. People get all kinds of nutrients and energy needed to maintain health through diet. Reasonable diet and adequate nutrition can improve the health level of a generation, prevent the occurrence and development of various diseases, prolong life expectancy and improve the quality of the people. Unreasonable diet, excessive or insufficient nutrition will bring different degrees of harm to health. Overeating can lead to obesity, diabetes, gallstones, hyperlipidemia, hypertension and other diseases, and even induce tumors in China, such as breast cancer and colon cancer. It not only seriously affects health, but also shortens life expectancy. Long-term nutritional deficiency in diet can lead to malnutrition, anemia, deficiency of various elements and vitamins, affect children's intellectual growth and development, and reduce human disease resistance and labor, work and study abilities. Malnutrition during pregnancy can lead to miscarriage, premature delivery and even deformity. Food hygiene is closely related to human health. Bacteria, molds, toxins and toxic chemicals carried in food enter the human body with food, which can cause acute and chronic poisoning and even malignant tumors. In a word, a proper diet has a great influence not only on one's health and longevity, but also on the health of future generations.
