Ancient oriental cultural system, medical writings, writers, religious scriptures, folk customs, there are many dietary taboos in the discussion, especially some ancient health practitioners, pay more attention to dietary taboos. Sun Simiao’s “regimen pillow in the square” said: “the disease is born horizontally, more by the diet of the disease, diet of the disease is too much sound and color, diet for the benefit of both wide, for the scourge of the deep, and the taste of a hundred products, touching its taboos, and more into the sinking of the poison, slow the accumulation of years and become sick, the emergency disaster and death also.” Clearly stated whether the diet is appropriate for human health is important. Ancient health practitioners also summarized the dietary taboos of the seasons: “Spring is good to eat spicy, summer is good to eat sour, autumn is good to eat bitter, winter is good to eat salty, all of which help the five organs, benefit the blood and Qi, and avoid all diseases. Eating sour, sweet and bitter, that is, not too much. Spring does not eat liver, summer does not eat heart, autumn does not eat lungs, winter does not eat kidneys, four seasons does not eat the spleen, if you can not eat these five organs, especially in accordance with the principles of heaven.” In short, the ancient health practitioners of this kind of exposition in particular, of which a considerable part does have a certain scientific reasoning.
Spring, the human body pores to adapt to the environment of gradually rising temperatures and gradually open. However, at this time the spring cold has not receded, it is easy to invade the human body muscles and bones, resulting in a variety of diseases. So the health care home that, in the spring, whether it is medicine or food, should be prohibited spicy and hair dispersal, so as not to make the pores more open, to the spring cold injury to the human body to open the door of convenience. Folk proverb says: “spring avoid ephedra summer avoid Su”, “Chrysanthemum, mustard are hairy, eat the whole body itchy scratch”. Jin Yuan famous doctor Li Dongyuan also believes that garlic, leeks, ginger, vinegar, dashi (such as fennel, pepper) class, are very powerful dispersal of products, people have consumed, can not eat more.
Summer weather is hot, people sweat a lot, body fluid consumption is very large, gastric secretion is reduced, so the digestive function is relatively weakened, coupled with the summer people like to eat cold food, making it more difficult to digest fatty food. It is easy to cause indigestion, enteritis and diarrhea. So in the summer in the diet, one is to avoid fat and greasy, the second is not too eat cold. All things in moderation is appropriate, too much will give birth to disaster. Nutritionists believe that the summer over-eating cold, not only will immediately induce enteritis, dysentery, gastrointestinal spasms, causing abdominal pain and diarrhea, will also make cholecystitis, gallstones, cardiovascular diseases, etc., occurring in the fall or attack.
Autumn is the season from hot to cool, hot and cold, the most susceptible to cold, but also the onset of old diseases, so the ancients attached great importance to the fall avoid cold. The law of heaven business” said: ”ten days after the fall, melon should be eaten sparingly.” Emperor Beijing Scenic Spectacle” said: ‘Autumn phase of the precepts do not drink raw water’. There are many health writings talk about the importance of eating less or forbidden to eat cold after the fall. Autumn also has a dry climate side, this cold and dry climate, so that people’s skin, mouth and tongue easy to dry, hair easy to fall off. The lungs are also very unfavorable, very easy to induce chronic bronchitis, tuberculosis, asthma, colds and other diseases. This is what is often called “dry can hurt the lungs”. Therefore, this season should avoid eating or eat less dry and tonic drugs or food. Should not eat dry rice, beef, turbid wine, lettuce, poisonous fish, stale and salty vinegar, sticky and slippery difficult to eliminate things. Do not eat more fried food, ginger and other spicy hot food and ginseng, deer antler and other tonic food. Eating these things tend to cause or exacerbate respiratory disorders.
Winter climate is dry, people eat relatively few fresh fruits and vegetables. More people are used to eating fried food, this eating method is very unfavorable to human health. Deep-fried food is a serious destruction of nutrients, the second is the oil by high-temperature pyrolysis, will produce polycyclic aromatic hydrocarbons, cyclic monomers, dimers and other harmful substances to the human body. These substances can cause liver damage, hepatomegaly or functional changes, slow growth, weight loss, and even reproductive dysfunction. In winter, when the weather is cold and people stay indoors, it is easy for them to catch fire. For a long time, to the late winter or spring, people will be more mouth and tongue ulcers, cough, tonsillitis, hepatitis, nephritis and many other diseases, people say “spring more disease”, is this reason. Spring to get sick more, commit more diseases, also lies in the winter indoor temperature is too high, eat barbecue hot food more, eat fresh vegetables, fruits and other reasons. Barbecue hot and other hot food to eat more, it will make people’s blood not smooth, all kinds of diseases that is born. Therefore, have to eat hot dumplings, hot steamed buns, hot wontons, drink hot porridge and other habits of people, to the spring and summer when it is necessary to the old disease attack, the new disease breeding.
Oriental yin and yang five elements doctrine, the universe of all kinds of things are given five elements attributes. However, there are only four seasons in a year, in order to match with the five elements, after determining the spring is wood, summer is fire, fall is gold, winter is water, and then from each season to take out 18 days of earth. The internal organs of human beings are also categorized into five attributes using the five elements: the liver is wood, the heart is fire, the lungs are gold, the kidneys are water, and the spleen is earth. Various foods are also categorized into five attributes. Thus, the season or month that advocates a certain attribute, it will be avoided to eat the attribute of the food, eat more of the attribute of the food. Such as “regeneration news” said: “summer month is fire. Mainly in the long heart gas, fire, taste is bitter. Fire can be grams of gold, metal lungs, lungs main pungent, when the flavor of summer diet, it is appropriate to reduce the bitter and increase the pungent.”
These theories, constructed a system of large and perfect food culture system, so that people are convinced.
