Principle: "Heaven and man correspond", and the inner diameter is "liver is healthy in spring, heart is long in summer, spleen is nourished in long summer, lung is nourished in autumn and kidney is nourished in winter." It shows that the physiological activities of the five internal organs of the human body must adapt to the changes of yin and yang in the four seasons in order to maintain a harmonious balance with the external environment. "Law is based on Yin and Yang, and skill is the basis. Diet is moderate, daily life is regular, and you get something for nothing ..." Diet in four seasons and health: climate has a very close relationship with people's health. According to the law of "spring in summer, long harvest in autumn and winter storage" in traditional Chinese medicine, this paper puts forward the method of keeping in good health all year round. 1. Spring: Everything revives and the climate changes greatly. Appropriate clothes should be changed according to the weather changes, but attention should be paid to the characteristics of "warm and cold at first" in spring, and it is not appropriate to take off the cotton-padded clothes immediately in early spring. The climate in spring is humid and warm, which is suitable for the growth and reproduction of bacteria and viruses. Attention should be paid to the prevention of respiratory infectious diseases. Spring is the season when everything grows, and people are no exception. The height of children and adolescents increases the most in spring, so it is necessary to provide nutritious meals for primary and secondary school students. 2. Summer: The climate is hot, the human body sweats a lot, the rest is not good, and the physical strength and gastrointestinal function have declined. In addition, the hot and humid climate makes the bacteria multiply rapidly. Therefore, special attention should be paid to food hygiene in summer to prevent the occurrence of digestive tract infectious diseases. At the same time, we should pay attention to a light diet and eat less frozen food to avoid damaging gastrointestinal function. 3. Autumn: The climate is dry and everything begins to gather. In terms of diet, we should eat more abundant food in protein to supplement the energy and nutrition consumed in summer. Especially for children and teenagers, it is easy to lose weight in hot summer, so it is more important to increase their nutrition. However, it should be noted that autumn is the harvest season, and the weight of children and adolescents increases the most in autumn. Attention should be paid to avoiding overnutrition and preventing obesity. In addition, due to the dry climate, the body, especially the respiratory tract, is in a state of water shortage, so we should pay attention to eating more fresh fruits and vegetables and drinking more soup and water in autumn. 4. Winter: the climate is cold, the plants and trees are dying, the insects and beasts are hiding, and everything is lurking and in a collection state. Chinese medicine believes that in winter, we should have enough sleep, prevent colds and keep warm, so that Yin and Yang Can can be stored, and Yin and Yang Can can be balanced to keep healthy. Winter is suitable for tonic, and children and adolescents are required to take food supplements as the mainstay, that is, to ensure a balanced diet, pay attention to the intake of a variety of high-quality protein and necessary inorganic salts, and reserve raw materials for spring growth and development. "It is advisable to eat sour in spring, bitter and hard in summer, spicy and divergent in autumn and salty and soft in winter." In spring, when everything in nature recovers and the anger is strong, we should eat less sour food and increase the sweet products appropriately. The diet should be light and mild, eat more fresh vegetables and less spicy sweets. Everything grows vigorously in summer. Because of excessive sweating and exhaustion of qi and yin in summer, it is advisable to eat foods that are cool and have the function of benefiting qi and nourishing yin. At the same time, we should pay attention to a light diet and eat less frozen food to avoid damaging gastrointestinal function. Autumn is dry, everything is withered, so it is advisable to eat foods that nourish the body and moisten the lungs, nourish yin and moisten dryness. Winter is cold, and everything is withered and hidden. It is advisable to choose meat food that warms and tonifies yang to help the human body hide yang.
