1. Nutrients needed by human beings
Human beings eat and drink every day, bit is to obtain nutrients. So, what are the nutrients that human beings need? Protein: It is a complex compound made up of a variety of amino acids. It is the basic material that constitutes the cell, is the main raw material for collective growth and repair of damaged tissues. It is the nutrient with the highest demand of the organism. Its large main sources are meat, eggs, milk, and certain plant seeds. Sugar: It is the main substance for the function of the organism and provides the energy needed for normal growth and activity of human life. It is mainly derived from rice, wheat, corn, etc. Fats and oils: are the body's main energy storage material, known as the alternate energy source for life activities, giving off about twice as much energy as sugars. At the same time, the fat in the human body has the effect of reducing the friction of the organs in the organism, and the organ anti-shock effect. Its main source of animal and vegetable fats and dairy products and so on. Vitamin: There are many kinds of vitamins, which mainly regulate the body's metabolism, prevent diseases and maintain health. Some of them can be absorbed from the outside world, such as vitamin A; some can only be synthesized in the body, such as vitamin D. The body's demand for it is very small, but can not be missing. Its main sources are fruits, vegetables, seed foods, animal liver and so on. Inorganic: It has a wide variety, but it is very important to the organism. It is involved in constituting tissues and regulating enzyme activity factors, and has a role in regulating cellular metabolism, hormone secretion, acid-base balance and so on. Water: accounts for sixty to seventy percent of the body. It is mainly for the body metabolism to provide a liquid environment, dissolve a variety of substances, to ensure that the body metabolism normally. Lack of water, human beings can not survive.
2. Understanding of health
Health has two aspects, one is physical health, the other is spiritual health. Spiritual health is mainly determined by an individual's mindset and emotions. The physical health of the body is mainly determined by the material input is whether to meet the needs of the body. Organism health first requires adequate input of nutrients. Nutrients are the basic substances that maintain the growth and development of the living organism. Without these nutrients, there is no life, let alone health. Therefore, we must first meet the material input requirements before we can talk about health. Various nutrients have different roles to play in the health of the organism, and what is required at the same time is the proper amount of input of that nutrient. If the intake is insufficient, then the organism will only be able to fulfill some of its functions normally, while others will be weakened or even missing. This is similar to the fact that some workshops in a factory have an adequate supply of raw materials and can produce normally, while other workshops have less raw materials and reduce production or stop production for the same reason. If too much is consumed, then it is not a good thing and is not good for your health. The excess nutrients cannot be utilized and will be eliminated through some other means. This is also harmful to certain organs of the body. At the same time, there are some that will accumulate in the body and form substances that are harmful to the body. For example, if you consume too much fat and sugar, it will form fat in your body, and too much fat will cause obesity. Therefore, the appropriate amount of intake of various nutrients, is to ensure that all organs of the body to work properly, each function effective premise, the disease can also be avoided, so as to achieve the health of the body.
3. Ancient human diet and health
Although the ancient science and technology is not as modern, but that is the human has also had the concept of diet and health. Most of the ancient Chinese thinkers were advocates of dietary restraint, believing that diets should not be excessive and should be kept within certain limits. This is not only beneficial to society, but also to the individual. Opposing the pursuit of thick and delicious flavors. While advocating dietary restraint, ancient Chinese thinkers also opposed the pursuit of thick and delicious flavors and advocated thin tastes. In the chapter "Lü Shi Chun Qiu? The exhaustion of the number of" chapter said: ? All food, no strong thick flavor, no strong flavor heavy wine. This is what is known as the head of the disease. Sickness of the head? The Qing dynasty Bi Yuan interpreted it as "the end of the disease". The root cause of disease. , that is, the root cause of disease. This is like anything, there is a certain limit, more than this limit will go to the opposite side of things, diet is the same, taste too thick. Instead, it will hurt the stomach and intestines, making the mouth tasteless. As Laozi? Taoist scripture" said? Five flavors make the mouth feel good? As Zhuangzi said, "the five flavors make the mouth feel good". and Chuang Tzu? The five flavors make the mouth feel good, and make the mouth feel good. The reverence for light, the pursuit of the original flavor, in response to the phenomenon of thick taste in the diet, some thinkers in the pre-Qin period and reverence for light, the pursuit of the original flavor of food. Laozi said: ? There is nothing to be done for, nothing to be done for, and nothing to be tasted for.? He also believes that the dietary activities in the light flavor is the first of all flavors. This is his reverence for nature, return to the true performance, reflecting his philosophy of doing nothing in the world. Advocating less meat and wine, ancient Chinese thinkers also put forward the idea of eating less meat and wine, the Analects of Confucius recorded the weekday life of Zuolu Zi, said: "Although more meat, do not make more than food. The Analects of Confucius recorded the daily life of ZiLzi, saying: "Even though there is a lot of meat, I don't want to win the food gas. And also said:? I don't want to be trapped by alcohol. Lü Shi Chun Qiu (The Spring and Autumn Annals of Lu Shi). Bensheng" even suggests: ? Fat meat and thick wine, things to strengthen themselves, life of the day rotten intestines of food. This shows that drinking and eating too much meat is detrimental to health and can even bring about unfortunate consequences. Ancient people believed that thrift is conducive to the stability of the regime. Some rulers in the pre-Qin period, also attaches great importance to advocate dietary moderation, against the thick taste, because the diet of frugality, the amount of food is also conducive to the stability of the regime. Historically, the overthrow of the Xia and Shang dynasties was caused by gluttony. In the "Strategies of the Warring States" (战国策?), Wei Ce? Wei Ce? recorded that Yi Di made wine and gave it to Yu, who said: ? Yu said: ?In the future generations, people will use wine to destroy their countries. Yu's prediction was fulfilled in his descendant Jie.
4. What is Nutritional Complementation
An important element of dietary fitness is the nutritional complementarity of a variety of foods. Any kind of food, it is not possible to the human body need nutrients are all included, such as the desire to obtain a variety of nutrients, it is necessary to a variety of different structures, different flavors, different varieties, different traits of food with mixed food, in order to receive nutritional complementary, nutritional? The effect of the combination of different structures, flavors, varieties and traits of food is to achieve complementary nutrition and nutritional? The role of nutritional complementarity. Mixed food methods are: animal and plant food with, main and side food with, coarse and fine food with, as well as advocate eating more fruits and vegetables, in order to meet the human body on fiber, vitamins and trace elements needs. Modern nutrition is concerned about the complementarity of nutrients? We often eat? tomato scrambled eggs? In fact, it is one of the most successful examples of food matching? Wang Yi, director of the Department of Food Therapy and Nutrition at the Guang'anmen Hospital of the China Academy of Traditional Chinese Medicine, said to reporters? Because eggs are rich in protein and a variety of vitamins such as B vitamins, niacin, lecithin and so on, but only the lack of vitamin C tomatoes contain a large amount of vitamin C just to make up for its defects, so the two together to eat can play a nutritional complementary role, which is precisely the modern nutritional focus on food matching. Like this example in our lives abound Wang Yi said, for example, we advocate that we should eat grains is also from the perspective of nutritional complementation to consider the most typical is beans. Beans are protein-rich food, but different kinds of beans have high and low amino acid content, so it is usually best not to eat only one kind of mixed food can improve the absorption of protein utilization and biological value. Lu Chunjing pointed out that some of the food with only due to a lack of understanding of the nutritional composition of food and lead to the wrong example of collocation is also quite a lot of consideration from the taste is likely to cause damage to health. For example, people often eat tea eggs tea in addition to alkaloids in addition to acidic substances, these compounds and eggs in the combination of iron on the stomach has a stimulating effect is not conducive to digestion and absorption. And eat? The best way to eat this dish is not to add the yolk. This dish is best not to add cucumber, which is Wang Yifan emphasized because cucumber contains an enzyme that can destroy the body's absorption of vitamin C in other vegetables. Unfortunately, nowadays the restaurant? The big bounty? Almost no cucumber is not added? Wang Yi on this nutritional loss due to improper food combinations.
5. Develop good healthy eating habits
According to the "Dietary Guidelines for Chinese Residents (2007)" can be seen in our country's national diet is very unhealthy, so we need to cultivate good eating habits. Good eating habits should include the following points: First, food diversity, cereal-based, coarse and fine mix. The nutrients contained in each kind of food are not exactly the same, each kind of food can provide at least one kind of nutrient. At the same time, we should pay attention to the mix of coarse and fine, often eat some coarse grains, mixed grains and whole grains. Second, eat more vegetables and fruits and potatoes. Vegetables and fruits are an important source of vitamins, minerals, dietary fiber and phytochemicals, with lots of water and low energy. Potatoes are rich in starch, dietary fiber and a variety of vitamins and minerals. Diets rich in vegetables, fruits and potatoes play an important role in maintaining good health, keeping the normal function of the intestinal tract, improving immunity, and reducing the risk of chronic diseases such as obesity, diabetes, and high blood pressure The third is to eat dairy, soybeans or their products every day. Milk has a full range of nutrients and the composition ratio feels especially sorry.
Suitable, easy to digest and absorb. Milk in addition to rich in high-quality protein and vitamins, high calcium content, and utilization rate is also very high, is an excellent source of dietary calcium. Soybeans are rich in high-quality protein, essential fatty acids, B vitamins, vitamin E and dietary fiber and other nutrients, and contains phospholipids, oligosaccharides, as well as isoflavones, phytosterols and other plant chemicals. Fourth, often eat the right amount of fish, poultry, eggs and lean meat. Fish, poultry, eggs and lean meat are all animal foods, which are good sources of high-quality proteins, lipids, fat-soluble vitamins, B vitamins and minerals for human beings, and are an important part of a balanced diet. Protein in animal food is not only high in content, but also more suitable for the human body's amino acid composition, especially rich in lysine and methionine, such as cereals or legumes with food, can obviously play a complementary role in protein: but animal food generally contains a certain amount of saturated fat and cholesterol. Excessive intake may increase the risk of cardiovascular disease, so it can not be too much to eat. Fifth, reduce the amount of cooking oil, eat light and less salt meals. Fat is an important source of human energy, and can provide essential fatty acids, is conducive to the digestion and absorption of fat-soluble vitamins, but too much fat intake is caused by obesity, hyperlipidemia, atherosclerosis and other chronic diseases, one of the risk factors. So we should develop the habit of eating light and less salt meals, that is, meals are not too greasy, not too salty, do not consume too much animal food and fried, smoked, pickled food. Sixth, eat fresh and hygienic food. Food left for too long will cause deterioration and may produce toxic and harmful substances to the human body. In addition, food may contain various harmful factors such as pathogenic microorganisms, parasites and toxic chemicals. Eating fresh and hygienic food is a fundamental measure to prevent foodborne diseases and achieve food safety. Avoid factory-processed foods. Those foods contain more food additives and are processed in an unhygienic way. By doing this and developing good eating habits, illnesses will stay away from us a lot accordingly. This is our current health quest mission.

The term "camp" is used in the Chinese language to mean "to seek" or "to seek". in Chinese characters is the meaning of seeking,? Nutrition? is to nourish or nourish the body, the combination of the two words together should be? The combination of the two characters should mean "seeking to nourish one's life". means to seek to maintain one's health. To be more precise, it should mean?
