1. nutrients needed by human beings
The purpose of human daily diet is to obtain nutrition. So, what nutrients do humans need? Protein: It is a complex compound composed of various amino acids. It is the basic substance of cells and the main raw material for the collective growth and repair of damaged tissues. It is the most needed nutrient for human body. Its main sources are meat, eggs, milk and some plant seeds. Sugar: it is the main substance of body function and provides the energy needed for normal growth and activities of human life. Mainly from rice, wheat, corn and so on. Grease: It is the main energy storage substance of the body, and it is called the reserve energy of life activities, releasing about twice as much energy as sugar. At the same time, the fat in the human body can reduce the friction of organs in the body, and organs can resist earthquakes. Mainly from animal and vegetable oils and dairy products. Survival: There are many kinds, mainly regulating the body's metabolism, preventing diseases and keeping healthy. Some can be absorbed from the outside world, such as vitamin A; Some can only be synthesized in the body, such as vitamin D, and the demand for it is small, but it cannot be lacking. Its main sources are fruits, vegetables, seed food, animal liver and so on. Inorganic substances: there are many kinds, but they are very important to the body. It is involved in the formation of tissues and the regulation of enzyme active factors, and has the functions of regulating cell metabolism, hormone secretion, acid-base balance and so on. Water: 60% to 70% of body. It mainly provides a liquid environment for the metabolism of the body, dissolves various substances and ensures the normal metabolism of the body. Without water, human beings can't live.
2. Understanding of health
Health has two aspects, one is physical health and the other is mental health. Mental health is mainly determined by personal thoughts and emotions. The health of the body mainly depends on whether the material input meets the needs of the body. Good health requires adequate nutrition input first. Because nutrients are the basic substances to maintain the growth and development of life. Without these nutrients, there would be no life and no health. Therefore, we must meet the demand of material input in order to talk about health. Various nutrients have different effects on health, and the input of nutrients is required to be appropriate. If the intake is insufficient, then the body can only meet some of its functions to be normal, while other functions will be weakened or even missing. This is the same reason that some workshops in a factory have sufficient supply of raw materials and can produce normally, while some workshops have less raw materials and reduce or stop production. If you eat too much, it's not a good thing and it's not good for your health. Too much nutrition can't be used, and it will be eliminated by other means. This is also harmful to some organs of the body. At the same time, some will accumulate in the body and form substances harmful to the body. For example, eating too much oil and sugar will form fat in the body, and too much fat will lead to obesity. Therefore, proper intake of various nutrients is the premise to ensure the normal work and effective function of various organs of the body, and diseases can be avoided, thus achieving physical health.
3. Diet and health of ancient humans
Although ancient technology is not as good as modern technology, it is the concept of healthy eating for human beings. Advocating diet, most thinkers in ancient China were advocates of diet, thinking that diet should be kept within certain limits. Doing so is not only beneficial to society, but also beneficial to individuals. Oppose the pursuit of coarseness and delicacy. Ancient thinkers in China advocated diet control, but also opposed the pursuit of thick and delicious taste and advocated thin taste. "Lu Chunqiu? The article "All" says:? There is no strong flavor in the place where you eat, and there is no heavy-flavored wine. It is called the first disease. ? The first disease? , qing bi yuan interpretation for? Jude's words caused disease? Which is the root cause of the disease. This, like anything, has a certain limit. If you exceed this limit, you will go to the opposite side of things, and so will your diet, which is too strong. On the contrary, it will hurt the stomach and make the mouth tasteless. Like "Lao tze? Tao Jing said? Five flavors are refreshing? , "Zhuangzi? Heaven and earth? The five flavors are turbid, which makes the mouth refreshing? . In view of the thick taste in diet, some thinkers in the pre-Qin period advocated light taste and pursued the original flavor in food. Lao Tzu said:? Doing nothing, doing nothing, is tasteless. ? He also thinks that the bland taste in food activities is the first of all flavors, which is the performance of his advocating and returning to nature, and embodies his philosophical thought of governing by doing nothing. Advocating eating less wine and meat, China ancient thinkers also put forward the idea of eating less wine and meat. The Analects of Confucius recorded Lu Zi's daily life. Although there is a lot of meat, there is nothing better than eating. ? Say it again: Wine is not sleepy. ? "Lu Chunqiu? "bunsen burner" even put forward: Fat meat is thick and wine is thick, things stand on their own feet, and intestinal food is rotten on the day of life. ? It can be seen that eating more meat is harmful to health and even brings unfortunate consequences. The ancients believed that thrift was conducive to the stability of the regime. Some rulers in the pre-Qin period also attached great importance to promoting diet and opposing thick taste, because frugality in diet and eating according to one's own stomach were also conducive to the stability of the regime. Historically, the collapse of Xia and Shang Dynasties was caused by gluttony. Warring States policy? Wei Ce? "According to records, Yidi brewing, into,:? Someone will kill the country with wine in the future. ? Yu's prophecy was fulfilled in his descendant Jie.
4. What is nutritional complementarity?
An important content of diet and fitness is the nutritional complementarity of various foods. No food can contain all the nutrients needed by the human body. If you want to get all kinds of nutrition, you must mix foods with different structures, tastes, varieties and properties to get complementary nutrition? Sang sang? Function. Mixed diets include animal and plant foods, staple foods and non-staple foods, coarse grains and flour and rice foods, and advocate eating more fruits and vegetables to meet the human body's demand for cellulose, vitamins and trace elements. Modern nutrition pays attention to the complementarity of nutrients? What do we often eat? Scrambled eggs with tomatoes? In fact, it is one of the most successful examples of food collocation. Wang Yi, director of dietotherapy and nutrition department of Guang 'anmen Hospital of Chinese Academy of Traditional Chinese Medicine, told the reporter? Because eggs are rich in protein and various vitamins, such as B vitamins, nicotinic acid, lecithin and so on. But it is only the lack of vitamin C. Tomatoes contain a lot of vitamin C, which just makes up for its defects, so eating together can play a complementary role in nutrition, which is the focus of modern nutrition. ? Examples like this abound in our lives. Wang Yi said, for example, we encourage people to eat miscellaneous grains from the perspective of nutritional complementarity, the most typical of which is beans. Beans are rich in food in protein, but the amino acid content of different kinds of beans is high or low, so it is best not to eat only one kind of mixed food at ordinary times, which can improve the absorption and utilization rate and biological value of protein. Lu Chunjing pointed out that some foods are mismatched just because they don't know the nutritional components of the food, and many examples are likely to cause health damage from the perspective of taste. For example, in addition to alkaloids, there are also acidic substances that people often eat in tea eggs. These compounds combine with iron in eggs, which stimulates the stomach and is not conducive to digestion and absorption. And eating? A bumper harvest? It is best not to add cucumber to this dish, which is emphasized by Wang Yi, because cucumber contains an enzyme, which will destroy the absorption of vitamin C by other vegetables. ? Too bad it's in the restaurant now? A bumper harvest? There are almost no cucumbers? Wang Yi is concerned about the loss of nutrition caused by improper collocation of this food.
5. Develop good and healthy eating habits
According to the Dietary Guidelines for China Residents (2007), we can see that the eating habits of China people are very unhealthy, so we need to cultivate good eating habits. Good eating habits should include the following points: first, food diversity, mainly cereals, thick and thin collocation. Each food contains different nutrients, and each food can provide at least one nutrient. At the same time, we should pay attention to the matching of thickness and often eat some coarse grains, miscellaneous grains and whole grains. The second is to eat more vegetables, fruits and potatoes. Vegetables and fruits are important sources of vitamins, minerals, dietary fiber and phytochemicals, with high water content and low energy. Potatoes are rich in starch, dietary fiber and various vitamins and minerals. A diet rich in vegetables, fruits and potatoes plays an important role in keeping healthy, maintaining normal intestinal function, improving immunity and reducing the risk of chronic diseases such as obesity, diabetes and hypertension. Milk is rich in nutrition, and the proportion of ingredients is particularly regrettable.
Suitable and easy to digest and absorb. Milk is rich in high-quality protein and vitamins, with high calcium content and high utilization rate. It is an excellent source of dietary calcium. Soybean is rich in high-quality protein, essential fatty acids, B vitamins, vitamin E, dietary fiber and other nutrients, as well as phytochemicals such as phospholipids, oligosaccharides, isoflavones and phytosterols. Fourth, eat proper amount of fish, poultry, eggs and lean meat. Fish, poultry, eggs and lean meat are all animal foods, which are a good source of high-quality protein, lipids, fat-soluble vitamins, B vitamins and minerals for human beings and an important part of a balanced diet. Protein in animal food is not only high in content, but also the amino acid composition is more suitable for human needs, especially rich in lysine and methionine. If eaten with cereals or beans, it can obviously play a complementary role to protein. But animal foods generally contain a certain amount of saturated fat and cholesterol. Eating too much may increase the risk of cardiovascular disease, so eating too much is not allowed. The fifth is to reduce the amount of edible oil and the diet is light and salt-free. Fat is one of the important sources of human energy, which can provide essential fatty acids and is beneficial to the digestion and absorption of fat-soluble vitamins. However, excessive fat intake is one of the risk factors of obesity, hyperlipidemia, atherosclerosis and other chronic diseases. Therefore, we should develop the habit of light and salty diet, that is, the diet should not be too greasy or salty, and we should not eat too much animal food and fried, smoked and pickled food. Sixth, eat fresh and healthy food. Food stored for too long will cause deterioration and may produce toxic and harmful substances to human body. In addition, food may contain various harmful factors, such as pathogenic microorganisms, parasites and toxic chemicals. Eating fresh and hygienic food is the fundamental measure to prevent food-borne diseases and realize food safety. Try to avoid eating food processed by the factory. Those foods contain more food additives and the processing process is unsanitary. By doing this and developing good eating habits, diseases will be far away from us accordingly. This is our current health pursuit task.
As a noun and term, nutrition has been widely used, but its exact definition may not be accurately understood. ? Camp? In Chinese, it means seeking. Raise? Is it health or fitness, which two words should be combined? Seeking health? The meaning of. Exactly, it should be? Seek health with food or beneficial ingredients in food? . ? Nutrition? The accurate and complete definition of this word should be:? By ingesting food, through digestion, absorption and metabolism in the body, the body uses the substances beneficial to the body in food as a process to build tissues and organs and meet the needs of physiological functions and physical activities. ? The knowledge of studying the nutritional problems of human body and other living things is called nutrition.
As the saying goes, health is the capital of revolution. With the continuous development of science and technology, health is really too important for us. Facing all kinds of delicious food in the present society, it is no longer a simple life. All kinds of delicious food are constantly emerging, and people are also very confused. A series of modern diseases such as obesity have also begun to appear. The course of food nutrition and health should be widely accepted by everyone. As contemporary college students, it is our unshirkable responsibility to learn and promote healthy eating. These premises are that we should know what nutrition is and what state belongs to health. We should not only achieve a balanced diet, but also pay attention to developing good eating habits.
In our life, we can't live without food, clothing, housing and transportation. Food is what we need every day, and nutritious food is the basic guarantee for our healthy life. Nutrition can regulate our health, so we should not only eat well, but also eat nutritionally, and understand the importance of complementary nutrition to our health. And develop a good lifestyle and healthy eating habits to lay a solid foundation for our healthy body.

abstract
With the development of economy and the improvement of people's consumption level, the proportion of dietary energy from carbohydrates is getting lower and lower, while the proportion from fat (especially animal fat) is getting larger and larger; At the same time, the proportion of energy provided by protein has gradually increased, and it began to supply energy with high fat, high sugar and high energy to economically developed countries? Three highs? The diet structure is close. The change of dietary structure has also significantly changed the disease pattern, that is, acute infectious diseases have dropped sharply, and cancer, cardiovascular and cerebrovascular diseases have increased significantly.
According to the correlation analysis, the consumption of cereals is obviously negatively correlated with the mortality of cancer and cardiovascular and cerebrovascular diseases, while the consumption of animals such as meat, eggs and oil is obviously positively correlated with the mortality of these diseases.
So what kind of diet is nutritious and healthy, which is in line with the way of health preservation? & gt& gt& gt More exciting next page? Nutritional diet and health paper 2000 words?
