question 1: essays on nutrition, balanced diet, health preservation, etc. (1) How to write the theme [2]

Graduation thesis can only have one theme (not several pieces of work pieced together), which should be specific to the grassroots level of the problem (that is, the problem can hardly be subdivided into sub-problems at a lower level), not the field to which the problem belongs, let alone the subject where the problem lies, in other words. Because the range of issues involved is too wide, it is difficult to study thoroughly in a master's degree thesis. Usually, a master's degree thesis should focus on a specific problem in a certain subject field and draw valuable research conclusions.

(II) How to write the title

The title of graduation thesis should reflect the main content of the thesis work concisely, and avoid being general. Because others want to search your paper through the keywords in your paper title, it is very important to use accurate language. The title of the thesis should be an accurate and concrete description of the research object, which generally reflects the research conclusion to a certain extent. Therefore, our thesis title should not only tell readers what problems this paper has studied, but also tell readers the conclusions drawn from this research.

(3) How to write the abstract

The abstract of graduation thesis is a high summary of the research content of the thesis, and others will search for a master's degree thesis according to the abstract, so the abstract should include: a description of the problem and the research purpose, a brief introduction to the methods used and the research process, and a brief summary of the research conclusion. It should be independent and self-evident, and it should be a complete paper.

(4) How to write the introduction

The introduction of a graduation thesis generally includes the following parts: 1. The question is raised; 2. The background and significance of the topic; 3. Literature review; 4. Research methods; 5. The structure of the paper.

Question presentation: explain what the question is.

Background and significance of the topic selection: explain why this topic is chosen for research, that is, explain the contribution of this research to the development of disciplines and its theoretical and practical significance to the national economy and people's livelihood.

literature review: make a detailed comprehensive review of the literature within the scope of this study. At the same time, there must be "comments" to point out the shortcomings of the existing research results and tell your own improvement ideas.

research methods: explain the scientific research methods used in the paper.

paper structure arrangement: introduce the writing structure arrangement of this paper.

The writing of "Chapter 2, Chapter 3, ……………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………… What has been said in the literature review part of the introduction does not need to be repeated here.

(5) the writing of the conclusion

The conclusion is the refinement and generalization of 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 achievements from those of our tutors and others.

Question 2: What a coincidence that the 5111-word paper on how to achieve a balanced diet. I have a similar one. Do you want it? Usually, the conclusion of a paper may not be limited to the memory of existing literature, because in this case, in order to compensate for the lack of literature in empirical research, the paper needs to reach a higher level of creative consideration. Therefore, the literature summary is usually only (once again) suitable for outstanding students or experienced researchers to challenge.

Question 3: Seeking a paper on balanced diet and healthy balanced diet refers to establishing a balanced relationship between dietary nutrition supply and physiological needs in four aspects at the same time, namely, amino acid balance, calorie nutrient composition balance, acid-base balance and various nutrient intake balance, which are neither lacking nor biased, but not chaotic. Only in this way can it be beneficial to the digestion, absorption and utilization of nutrients. If the relationship is out of balance, 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 number and proportion of eight essential amino acids contained in food. Only when the number and proportion are close to the needs of human body can we synthesize human tissue protein. Otherwise, it will affect the utilization of protein in food. The World Health Organization put forward a ratio of eight essential amino acids needed by human body. The closer the ratio is, the higher the physiological value is. When the physiological value is close to 111, 1111% of it is absorbed, which is called total amino acid balance. Protein, which can achieve full balance of amino acids, is called 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, so it can be called food with balanced amino acids. Most foods are unbalanced in amino acid composition, 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, a plant-based diet should pay attention to the reasonable collocation of food and correct the imbalance of amino acid composition. If cereals and beans are mixed and made into soybean corn flour and soybean millet flour, the utilization rate and nutritional value of protein can be improved.

(2 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 61-71% of human thermal energy comes from carbohydrates, 11-15% from protein and 21-25% from fat. According to this composition ratio, and considering the difference of energy produced by different nutrients (1 g of protein or sugar can produce 4 kilocalories, and 1 g of fat can produce 9 kilocalories), the intake ratio of the three major thermal nutrients in food is: carbohydrate: protein: fat = 6: 1: 1.7.

When dietary fat and calories are provided too high, it will cause obesity, hyperlipidemia and heart disease. When protein heat supply 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 carbohydrate and fat are in short supply, it will weaken the protection for protein. The three factors influence 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 31%, lunch accounting for 41% and dinner accounting for 31%.

(3) Balance of intake of various nutrients

There are complicated relationships among various nutrients, and the requirements of nutrients are different in different physiological states and different activities, so the China Nutrition Society has formulated the daily supply of various nutrients. All kinds of nutrients in our diet are kept within the range of less than 11% of the standard supply within a certain period. This mutual ratio can be called the basic balance between nutrients.

according to the "pagoda of balanced diet", we know that each person should eat (based on raw food) 311-511g of grain, 411-511g of vegetables and fruits and 111-211g of animal food such as fish, poultry, meat and eggs (51g of fish and shrimp, 51-111g of poultry meat and 25g of eggs) 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. People will maintain the acid-base balance of body fluids if they eat proper amount of acidic food and alkaline food, 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 and flowers ... > >

question 4: under the importance of reasonable nutrition and balanced diet to human health, the wind of "detoxification" is prevalent. There are at least ten books of "detoxification" in bookstores, and there are more and more "detoxification" in newspapers and online. In fact, when the wind of "detoxification" first started, it was a few people who called themselves "nutritionists" without receiving medical education or formal nutrition education, and said "detoxification". In order to improve the ratings and attract the audience's attention, some media add fuel to the fire by giving these "alternative" people the titles of "internationally renowned experts" and "doctors in nutrition". People who don't know what to do think that real experts have come and brought them the gospel. As a result, "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 medical experts who have received formal medical education have also participated in the promotion of "detoxification", which makes me very puzzled. In April, I had the honor to participate in the debate on "Detoxification" in the "Chen Rong Blog" program of the news and entertainment channel of Shanghai TV Station. Recently, I read more than 11 books on "Detoxification" and browsed thousands of information on "Detoxification" online, which was quite emotional. The direct feeling was that the "Detoxification" wind disturbed 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 the year when a health care product manufacturer proposed to eliminate "garbage in the body", to today's "poison" and "toxin" are rampant, so that advertisements like "Have you detoxified today" are more and more deeply rooted in people's hearts, until they are alarmist and endanger the public. What does the so-called "poison" mean? In a word, the explanation of human endotoxin by Chinese and western medicine is the metabolites in the human body. Today, it should also include: exogenous toxins, that is, bacteria, viruses and other microorganisms that invade the human body; Residual pesticides and environmental pollution on fruits and vegetables in the cannibal body lead to excessive heavy metals in the human body. In addition, there are psychotoxins, which may cause harm because of the stress of modern people's life, causing the increase and accumulation of metabolites in the body. Among them, the most important are the human body's own metabolites, especially ammonia and nitrogen-containing compounds produced by protein's metabolism, such as creatinine, urea nitrogen and uric acid.

so, what is "detoxification"? Most 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, such as the waste produced by metabolism in the body 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 all excrete toxins. The human body itself has a strong "detoxification" ability, and defecation, urination and sweating are "detoxification". In most cases, as long as the human body functions normally, it can completely rely on its own "detoxification" function to basically expel toxins from the body without the help of external forces. 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 external 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 stone obstruction. However, if the large intestine is cleaned for a long time, the nutrients will be washed out with the cleaning, so that the nutrients will not be well absorbed. Moreover, the defecation function of the large intestine may become dependent on artificial washing after repeated "intestinal washing 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, hypertension, perianal diseases and anemia, pre-pregnancy and just undergoing surgery are not suitable for intestinal lavage. Another example is taking drugs to relieve constipation and "detoxify", which is not a cure. These drugs contain rhubarb more or less, and rhubarb contains a lot of tannins. Small doses not only have no purgative effect, but also have astringent effect.

Relevant experts believe that rhubarb has the main function of anti-inflammatory and catharsis to some extent, but it must not be taken for a long time. Like drugs, some of them will become "addicted" and dependent, and once they stop taking drugs, they will have secondary constipation. In addition, taking rhubarb for a long time will inhibit your own immunity. Some people eat rhubarb and have side effects, such as abdominal pain and mild nausea. If we rely on purgation for detoxification for a long time, it may affect the absorption of certain nutrients by the human body over time, resulting in anemia and other adverse consequences.

question 5: the importance of reasonable nutrition and balanced diet to human health. Reasonable nutrition and balanced diet are very important to human health. Uneven nutrition makes people's bodies prone to problems, so diseases arise at the historic moment.

Question 6: Ask for a small essay with the theme of balanced diet of at least 811 words. Write it yourself, and don't copy it online. After answering the prize, add 21,111 points. Life is short. Obviously, health is everything to people. Some people say that health is 1, and wealth, career, love, etc. 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 our society today. We are at an important age 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 their texture is soft and weak, and their physical and psychological conditions are not resistant to stress; 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 and health care 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. "Food is the most important thing for the people, and safety is the first thing to eat." All of us should pay attention to scientific diet, eat well, eat to support people, not eat to hurt people.

However, we can see that many students are drinking carbonated drinks before and after meals, regardless of spring, autumn, winter and summer. Every time you have a meal, you can see many people making instant noodles, and the aroma is overflowing. There are also some students who buy takeout from vendors outside in foamed plastic. On the roadside outside the school gate, on the dusty roadside, eating roadside barbecue with relish.
