“People are food-oriented”. Diet is the only source of nutrients required for human life and functional activities. Therefore, the diet should be reasonably structured, with three meals a day and seven points. Satisfying body nutrition is the prerequisite to ensure physical and mental health, plus physical exercise and psychological balance to be considered physically and mentally healthy. “People take food as the day”, “seven days without grain will die”, all indicate that diet is vital. This is because all the nutrients needed for human life and visceral functions are derived from the diet. Solid food for food, liquid for drink, together called diet. In fact, the two have their own characteristics, the function is very different: solid food, difficult to digest late, full of hunger and stomach for the specialty, the spleen and stomach strong people appropriate, but also must be paired with the soup and porridge drink, only reasonable, comfortable, scientific. Therefore, folk have “original soup into the original food” said. Nutritionists also say: “eat first soup, slim and healthy”. Southerners in China have such good dietary hygiene habits: soup, porridge, soup, paste, tea for the drink, both the most easily digested and absorbed, very nutritious, but also the best stomach and spleen, spleen and stomach weakness, recovering from a serious illness, indigestion, this drink is the most appropriate, in order to recuperate the most good. We know the importance of diet, but also to know the scientific dining, reasonable with the dietary structure. Thousands of years of dietary culture have given birth to the unique dietary structure of Chinese people: a balanced dietary structure with grains as the mainstay and meat, eggs, cream, fruits and vegetables as supplements. The Chinese medical classic “Nei Jing”, which was written more than two thousand years ago, sums it up as follows: “Five grains for nourishment, five fruits for help, five animals for benefit, and five vegetables for enrichment”. Each type of food has its own strengths, complementing each other but not replacing. Therefore, to “eat the whole”, “eat all”, in order to rich and balanced nutrition. “Eat whole” is a complete variety of food, vegetables, fruits, meat, eggs and cream, can not be partial food, and a reasonable proportion of matching, coarse and fine grains are eaten; “eat whole” is to eat all of the root of a certain food, such as celery leaves are more nutritious than the stem, rice and wheat and other grains near the skin contains Vitamins, crude fiber most, eat fine rice and flour alone is too bad. In addition to eating all and eat all, but also to eat a diet, doctors have a famous saying: “seven minutes full diet, no disease live to old age”. Do not overeat, hunger and fatigue, so as not to damage the spleen and stomach. Doctors warned: “diet since the times, the intestines and stomach is injured. Three meals a day, seven is appropriate. Breakfast should be early, the quality should be high, rich in protein, carbohydrates and sugar and so on; lunch should be good; dinner should be less. Night meal is not good, even if it is necessary, should be less, so as not to affect sleep and damage the spleen and stomach. Chinese medicine has “stomach and restlessness” theory. To do regular rationing, hunger and food, do not eat too much, not full that is just right; thirst and drink, do not drink too much, frequent and often drink, only for science. How is the diet digested? Chinese medicine says: “The stomach is the main receiver, the spleen is the main transporter”. The procedure of entering the body is oral → esophagus → stomach → small intestine → large intestine → anal discharge, which is the channel of food in the human body, only the channel is regulated in an orderly manner, in order to facilitate full digestion and absorption. Chinese medicine says that we have to pass through the “seven rushing doors” (flying door, door of the family, sucking door, cardia, pylorus, appendix, pranic door). This is described in the Book of Difficulties: “The lip is the flying door, the tooth is the door of the house, the meeting is the sucking door, the stomach (upper mouth) is the cardia door, the lower mouth of the taicang (stomach) is the pylorus door, the large and small intestine (intersection) will be the appendix door, and the lower pole is the pylorus door”. These seven gates constitute an orderly channel for the transmission and digestion, absorption, excretion, and regulation of diet in the body. The digestion of food and drink begins through oral chewing. Chewing has a great impact on the entire digestive process, and repeated and sustained chewing can significantly improve the brain’s thinking ability, increase the transfer of information from brain cells, and improve the efficiency of the brain, obviously more chewing and slow swallowing is extremely important for digestion and thinking, so Chinese medicine has “the spleen is the main think” theory, fully explaining the ” The importance of “chewing and swallowing slowly”. When the chewing is completed, large pieces of food into smaller particles, the natural start of the aversion of this pass, through the “suction door” of the absorption, guidance, so that the food orderly and smoothly into the esophagus. Because the esophagus and trachea meet, when swallowing, the eclipses block the tracheal opening and open the esophageal opening, and then run to the stomach through the cardia gate. The peristaltic movement of the stomach with a variety of digestive juices in the stomach to decompose and digest the food, so that small particles of food change into smaller chyme-like, before starting the pylorus of the winding path, smoothly into the small intestine. The small intestine is the main place for digestion and absorption of food, which is called “the official of receiving Sheng” in Chinese medicine, and its function is to “distinguish between clear and turbid”. It means to accept the food and drink transmitted by the stomach, further digest it, absorb the essence of nutrients in the food and drink, participate in blood circulation, and transport it to the whole body. At this time, the “appendix” should be activated to pass the residual dregs to the large intestine. “The large intestine is the official of conduction. Further absorption of its excess water, forming stool, conduction to the anus, and start the prana (anus), discharged from the body. There is also the bile which stores bile and helps with digestion. The three jiao, the bladder has both the task of transporting essence and the task of metabolizing, excreting and storing water and fluids. In Chinese medicine, “the six internal organs are not hidden, so they are full but not real”. The function of the six internal organs is highly summarized. Among them, the stomach, gallbladder, large and small intestines complete the digestion, absorption, transmission, conduction and excretion of food; Sanjiao and bladder complete the transmission of essential nutrients and metabolism of water and fluids. With a reasonable diet and a strong spleen and stomach, we can ensure nutrition, digestion and absorption, and have the basis of the body’s health, plus regular physical training and mental balance, we will become a “healthy person” with physical and mental health.
