The history of TCM diet can be traced back to more than 3000 years ago, and there has been a saying that "medicine and food are homologous" since ancient times. Nowadays, it is customary to call diet health preservation "food tonic" and "food tonic", which means to strengthen the body, nourish the body and delay aging through diet under the guidance of Chinese medicine theory. "Su Wen? The theory of storing qi points out that the diet should be based on "five grains as nourishment, five fruits as help, five livestock as benefit, five dishes as filling, and the smell should be consistent to supplement the essence". Because diet is the main material basis to ensure that the body is full of qi and blood and the functions of the internal organs are vigorous, scientific and reasonable arrangement of diet can improve the health level of the body and resist the interference of external evils. The so-called scientific and reasonable arrangement of diet includes not only reasonable diet deployment, moderate diet and food hygiene, but also post-meal health care and post-meal conditioning, such as walking after meals and rubbing the abdomen.

However, due to modern people's high work pressure and fast pace of life, the unique diet that emerged at the historic moment often makes the body either hungry or overeating, resulting in the body being unable to absorb nutrition according to certain rules. In addition, unreasonable diet collocation leads to the superiority or decline of diet types, which leads to the excess function of a certain zang-fu organ or the lack of a certain food component in the body, thus leading to diseases. Modern research has known that the lack of certain food ingredients in the human body can lead to diseases. For example, excessive consumption of fat and sweets can cause blood lipids, blood pressure, elevated blood sugar, overweight and so on. In addition, dietary preference can also lead to visceral dysfunction.

For example, "Su Wen-Nutian Tong Lun" pointed out that "the taste is too sour, the liver qi produces fluid, and the temper is absolutely; The taste is too salty, the bones are exhausted, the muscles are short and the heart is depressed; The taste is too sweet, the heart is full of asthma, the color is black, and the kidney is unbalanced; The taste is too bitter, the temper is not strong, and the stomach is strong; The taste is too spicy, the bones and muscles are slack, and the spirit is awkward. " "Therefore, I would like to agree with the five flavors. Bone full of tendons, blood flow, dense management. If so, you will be fine, and you will have a destiny. " This means that the five flavors of diet must be reconciled, and the diet must be appropriate, so as to fully nourish the five internal organs, and not to be partial to one or a certain type, otherwise it will easily lead to imbalance between yin and yang and produce diseases.

In traditional Chinese medicine dietotherapy, the homology of medicine and food has always been a major feature of traditional Chinese medicine dietotherapy. In the application of dietotherapy or adjuvant treatment of diseases, its function is basically the same as that of drug therapy, and it mainly focuses on eliminating pathogenic factors and strengthening the body resistance, which embodies the principles of "deficiency is tonic", "excess is diarrhea", "cold is heat" and "heat is cold". Modern research, such as raw hawthorn and oats, can lower blood fat, celery and auricularia can lower blood pressure, lotus seeds, lilies and longan can soothe the nerves, and walnuts can eliminate brain fatigue. In short, there are countless examples of diet conditioning or body treatment. Therefore, reasonable arrangement of diet and nutrition are the main methods to ensure the vigorous function of zang-fu organs and the fullness of qi and blood, which can play a certain role in intervention and treatment of sub-healthy people.

Step 2 live and stay healthy

Relevant research shows that sub-health people are mainly concentrated in the age of 30-55, and most of these people are in a period of vigorous physical or mental activity. Being in a state of fierce competition and overload operation for a long time is generally manifested in irregular work and rest, impermanence of daily life, and lack of exercise and self-regulation, which leads to physical and mental fatigue, fatigue, forgetfulness, insomnia, dizziness, headache and other symptoms that cannot be alleviated.

Traditional Chinese medicine emphasizes the combination of routine and activity, in which routine mainly refers to daily life, including eating, wearing, living, standing, sitting, lying down, enjoying life and relaxing body and mind, which can have certain rules and conform to the natural and human physiological routine, so as to achieve the purpose of strengthening the body and prolonging life. The so-called law refers to objective rules and commandments. Modern medicine has proved that human life activities follow a certain cycle or rhythm. After acquired training and cultivation, the regulatory activities of the human cerebral cortex have formed a rhythmic conditioned reflex system. Once the conditioned reflex system is established, its activities are relatively stable.

Regular living habits can establish various conditioned reflexes in the nerve center of the brain, and make them constantly consolidated, forming good living habits. Good living habits can improve the adaptability of the human body, care for people's air, and make people energetic and energetic. On the contrary, irregular life and rest will lead to premature aging and even disease. Just as Neijing said: "Life is unrestrained, so it is half-baked." Therefore, forming regular living habits, sleeping and getting up on time, eating on time, and working and studying regularly are beneficial to health and longevity.

In addition, the combination of static and dynamic, moderate work and rest also plays an important role in human health care. Sun Simiao mentioned in "In case of emergency": "The way to keep fit is to work hard, but not to be tired, but to be strong." This means that people should have proper labor (including physical strength and mental power) in daily life, which can play a role in strengthening the body, strengthening the body, exercising the bones and muscles, exercising the will and regulating the spirit. However, the relationship between work and rest is contradictory and coordinated with each other. You can neither overwork nor relax. They need balance, work and rest combined with exercise, which is beneficial to the human body.

3. Emotional health

Modern people are in a fast-paced and highly tense competitive environment for a long time, which leads to the disharmony between mental state and social adaptability. Psychosomatic symptoms caused by mental factors have become a common phenomenon in sub-healthy people, such as depression, upset, anxiety, loneliness, inattention, and difficulties in work and study. Therefore, mental health care has become one of the important factors of human health.

Traditional Chinese medicine believes that people have seven emotions, which not only affect the blood operation of human qi, but also affect the functional activities of internal organs. For example, Neijing pointed out: "Anger hurts the liver, delights in sadness, misses the spleen, mourns the lungs and fears hurting the kidney", "Anger leads to qi rising, happiness leads to qi slowing down, sadness leads to qi disappearing, fear leads to qi falling, shock leads to qi disorder, and thinking leads to qi depression". Therefore, doctors in all previous dynasties regarded spiritual cultivation as an important part of health and longevity, and believed that "the spirit is clear and harmonious, and the heart is harmonious", "I have no worries in my heart, take pleasure as my service, take self-satisfaction as my contribution, keep in shape, and keep in mind."

The main methods of mental adjustment are quiet mental adjustment, determination mental adjustment, cheerful optimism, emotional adjustment, psychological balance and so on. Meditation, qigong, piano, chess, calligraphy and painting, exercise and other methods can be used to make the mind calm, cheerful, firm in faith, maintain peace of mind, indifferent to humiliation, and comfortable in form and spirit, so as to achieve the effect of "indifferent to nothingness, conforming to the true qi, hiding the spirit inside, and preventing illness"

The World Health Report in 2008 called for a return to primary health care, arguing that the current concepts, principles and methods of primary health care are more applicable than ever. Because the current mode of providing medical care often focuses on diseases, high-tech and professional medical care, health is regarded as the result of biomedical intervention, and the preventive role is largely ignored. According to the data of the World Health Organization, if we can make better use of existing preventive measures, the global disease burden can be reduced by 70%. Traditional Chinese medicine has summed up many valuable experiences in its long-term practice and development, and the formed preventive health care system has all-round advantages that modern medicine can't match. Understanding and treatment of sub-health in traditional Chinese medicine,

Compared with western medicine, it has the characteristics of less cost, less side effects, obvious curative effect and diversified treatment methods. In terms of adjustment, we advocate the principle of adapting to people, time and local conditions. In terms of health care and conditioning, in addition to the above methods, there are different methods such as health care acupuncture, massage, bath lotion, sleep, fitness, etc., that is, the so-called "mixed therapy, each with its own uses." Under the guidance of holistic view, it is different from western medicine to promote the recovery of yin-yang balance and prevent the occurrence and transformation of diseases by adjusting the viscera and qi.

Although the emergence of sub-healthy people has not reached the diagnostic standard of diseases, it has reflected the disharmony of physical, psychological and social environment. These disharmonies can be transformed into normal health through appropriate preventive measures, and will further develop into diseases if they are not intervened. Traditional Chinese medicine health care method is unique and practical, and it is gradually welcomed and popularized by most people in western countries.
