As early as two thousand years ago, Chinese medicine talked about health and longevity, which was called "keeping in good health" at that time, also called "Shen Tao", "recuperating life" or "nourishing nature". Its purpose is to strengthen physique, prevent diseases, prevent premature aging and prolong life. The author talks about his health care experience through his own practice of traditional Chinese medicine, hoping to play a role in attracting jade. In the aspect of spirit, ancient physicians attached great importance to the role of mental factors in the occurrence, development and transformation of diseases, and had been able to initially apply the theory of nerve reflex to understand physiological and pathological phenomena and treat diseases. For example, Su Wen in Neijing said: "The head is the house of wisdom …", "The heart is the official of the monarch, and the way of God comes out …", and the twelve officials will never lose each other. Therefore, if you master the Ming Dynasty, you will be safe and healthy, and you will live a long life ... If you don't take charge of the Ming Dynasty, you will be in danger. ”。 Here, the head and heart refer to the brain and cerebral cortex, which has implicitly explained the theory that higher nervous activity is the master of the organism, and the cerebral cortex is associated with visceral activities. Therefore, the ancients attached great importance to spiritual activities in health preservation, and taught people to be "quiet and empty, follow the true qi, and hide the spirit inside ..." It means that pure and stable thinking, optimistic and cheerful mood, and full of energy can enhance the body's resistance and prevent diseases. At the same time, it is believed that people's spiritual activities should be adjusted accordingly with different seasons, and it is pointed out that "spring and March should make people yearn for life; Summer and March should make volunteers not angry; Autumn and March should make the pool peaceful; Winter and March should make the ambition hidden. " The above wishes represent spiritual activities. The ancients believed that "emotions can lead to dirtiness" and "all diseases are caused by qi". For example, Su Wen in Neijing said that "the five internal organs can generate five qi, producing emotions and fears ..., anger hurts the liver, likes sadness, misses the spleen, and fears the lungs and kidneys". "Yang qi, great anger leads to exhaustion of qi, and blood on the body makes people faint". It is believed that excessive sadness or joy will weaken the body's resistance, cause visceral diseases or easily feel bad external stimuli and cause diseases. The author believes that any psychological change will affect the smallest cell of the organism and affect the health of the organism. For example, a relaxed and happy mood can enhance immunity, prevent the spread of diseases, and even prolong the life span of cancer patients. On the contrary, depression and nervous mood will destroy the immune ability of the body, make people easy to get sick or affect the therapeutic effect of diseases. Diet is a necessary condition for human survival, but hunger, cold and heat and overeating will always damage the spleen and stomach, thus affecting the acceptance and transportation of food, leading to illness and even death. As the saying goes, "the day when the eater gives birth to the people is also the foundation of the living." "Difficult Classics" said that "people live on food, the taste of grains, tonify the body and raise hair, and the stomach is the sea of water and valleys, which is based on stomach qi during the four seasons". It shows that food intake is the source of growth, development, maintenance and improvement of health. The ancients repeatedly taught people to eat moderately and not to overeat, pointing out that taking wine as the marrow and uncontrolled diet are important factors for weakness and premature aging. The ancients also attached great importance to the nutritional value and cooking technology of food. Su Wen recorded that "five grains are for nourishment, five fruits are for help, five animals are for benefit, and five dishes are for filling". In addition, it also expounds that improper collocation of five flavors in diet can produce various pathological changes and clinical symptoms. For example, Su Wen Zhong-yun said: "Eating more salty food will make the pulse condition sob (astringent) and discolor; If you eat too much, your skin will wrinkle and your hair will pull out; If you eat more spicy food, your muscles will be anxious and your claws will dry up; If you eat too much acid, the meat will be tender and your lips will be exposed. Eating too much sweets will lead to bone pain and fall, which is also the injury of these five flavors. "It also teaches people to adjust the hot, cold, dry and wet of food according to the changes of seasons. For example, Hu Sihui of the Yuan Dynasty wrote "Eating is Right": "It is advisable to eat wheat to cool down in spring; It is hot in summer and should be eaten cool; Autumn dryness should be eaten with hemp to moisten its dryness; It is advisable to eat cold in winter and treat its cold with heat. "In addition, it is also opposed to eating too much fat, so the cloud" sorghum changes, enough to give birth to a big pot "shows that eating too much fat is easy to cause carbuncle and swelling, and emphasizes that a balanced diet of five flavors can maintain the normal physiological function of human bones and muscles, make people healthy and live longer, which is called" smelling and nourishing thin "and eating vegetarian food for a long time can prolong life. In my opinion, besides ensuring daily nutrition and eating some foods rich in protein, it is best to eat less sugar and high-fat foods and more foods rich in cellulose. Foods rich in cellulose can accelerate intestinal peristalsis, reduce blood lipids and cholesterol, and leave some carcinogens without breeding soil. Avoid overeating, avoid simple obesity and increase the burden on digestive organs and kidneys. In addition, salt, tobacco and wine should also be properly restricted. Reasonable dietary arrangement is the material basis for good health, energy and longevity.
