[Reprint] Is Fasting Healthy? Is fasting harmful to the body?

"Fasting is secularized fasting, fasting is mystical fasting" Fasting in ancient times, had been used as an important means of Taoism used to cultivate immortality, cultivating immortality, people believe that the five grains are all turbid gas, and the heavenly realm is the place of the most clear, if you do not remove a body of turbid gas will not be able to be immortalized. Including Christianity, Islam, etc. have similar fasting teachings and regulations, which makes fasting from the popular level of knowledge seems to be a kind of feudal superstition, but also covered with a layer of ignorance color. Chinese medicine believes that the amount of grains and cereals into the human body, through the transportation of the spleen into the body's necessary qi, blood, essence and fluids, but if you eat too much, it will not be conducive to good health "phlegm-dampness", that is, modern medicine that the fat, lipids, metabolism, etc., and therefore the traditional health sayings there is such a sentence: Therefore, there is a saying in traditional health care saying: "If you want your body to be safe, you should always bring three points of hunger and cold".　　　　However, Prof. Qin Jian pointed out that fasting and fasting, from not eating this level to talk about, they are basically equivalent, but fasting is different from fasting is based on scientific medical means. Fasting can be categorized into short-term fasting of two days on weekends for health care and long-term fasting of 7-11 days for medical treatment of diseases. Short-term fasting does not require strict procedures, while fasting for more than two days must be carried out in a hospital under the close supervision of medical staff on all body functions. According to Professor Qin Jian, "Fasting is a secularized version of fasting, and fasting is a mystical version of fasting. Fasting is not something to be taken for granted, it must be carried out in strict accordance with the medical monitoring and process to ensure that the treatment of disease on the basis of not causing harm to human health."　　　　Fasting to do a good job "trilogy", drink more water is the first thing Prof. Qin Jian said that, in general, at home on their own for two days of short-term fasting is very safe, in principle, there is no special attention to the place, but if the fasting can be in accordance with the "trilogy" to be carried out! It is better: the first step: buffer. Workers who want to carry out the weekend fasting, then from Friday can start to prepare. This preparation is not "tomorrow and the day after tomorrow can not eat anything, I eat a little more today to save it", but consciously reduce the amount of food, through only the intake of fruit and water to give the body the signal of insufficient energy, in the body of energy intake is insufficient, the brain will order the body to gradually shut down the body's various non-essential functions to ensure that the body in the absence of energy intake. The body is able to function normally when there is no energy intake.　　　　Step 2: Fasting period. At the beginning of the fast on Saturday, you can drink 500ml of warm water with Xuanming powder (sodium sulfate) to achieve the effect of "cleansing". However, Prof. Qin Jian emphasized that this kind of "intestinal cleansing" is not to remove the so-called "hangover" or "detoxification", but to empty the intestines and reduce the intestinal garbage for the intestinal stimulation, which in turn reduces the intestinal irritation. It is to empty the intestines, reduce the stimulation of the intestinal tract by intestinal waste, and then reduce the body's hunger. After emptying the intestines, people can live a normal life and even do light exercise, including jogging, yoga, walking and other light and non-strenuous exercise, but Prof. Qin also reminded: it is best not to drive and climb higher during the period of fasting, so as to avoid the danger of insufficient body energy. At the same time, he emphasized that one should drink more water than usual during the fasting period so that the water can flush out waste products such as uric acid and ketoacids from the body. Water intake should be around 3,000 ml per day, and if hunger is too strong, vegetable or fruit juices can be consumed appropriately. If a strong feeling of discomfort arises, fasting should be stopped immediately so as not to bring about a life-threatening situation.　　　　Step 3: Recovery period. After two days of short-term fasting in the weekend, normal diet can be resumed from Monday, but since the stomach has been shrunk by starvation in the two days of the weekend, the amount of food will be smaller than usual, and it can be taken in the form of gradual recovery by eating more vegetables and fruits, and it is not possible to eat a big meal of fish and meat as if you have been liberated, or else the burden on the intestines and stomach will be increased, and you will feel indigestion or even flatulence and pain.　　　　The first time you fast, you may experience some discomfort from hunger, but after a few repetitions, you will find that the discomfort disappears and you will benefit from it.　　　　Fasting can treat gastritis and other digestive diseases, and will not cause damage to the stomach We often hear that so-and-so because of long-term irregular diet or long-term not eating breakfast, and finally found to be stones or even stomach cancer, which makes people have more and more deep and horrible knowledge of the "harm of irregular diet", so two whole days in addition to water do not eat anything, the stomach and gallbladder and other digestive organs, will not be able to eat. So if you eat nothing but water for two whole days, will it harm your stomach, gallbladder and other digestive organs? Prof. Qin Jian replied that the existence of gallstone risk is undeniable, but he also believes that the existence of risk does not necessarily mean that you will get it, and that if fasting can cure more serious and life-threatening diseases such as coronary heart disease and atherosclerosis, then the trade-off between the two should be to choose the practice that is good for your overall health.　　　　In addition, conscious and active fasting not only does not harm the stomach, but even in turn can cure gastritis and protect the stomach. He said, for example, most of the drivers in the past have stomach problems, this is because they want to eat after the meal time but may not have time to eat, but because the brain is constantly imagining the delicious food, the gallbladder will begin to automatically secrete bile, the stomach will automatically secrete gastric acid, but there is no thing for the stomach to digest, the gastric acid will continue to stimulate the gastric mucous membrane, aggravating gastric problems. However, after buffering, fasting therapy, the body itself realizes that there is nothing to eat for these two days, and with this subjective awareness suppressing the relevant reflexes of the nervous system, the stomach will not secrete gastric acid, which in turn is able to alleviate the burden on the stomach and treat gastritis. This is the principle behind the fasting treatment given to many patients with gastric bleeding.　　　　Who is suitable for fasting?　　　　Fasting is good, but not everyone can try it as a matter of course. Prof. Qin Jian pointed out that short-term fasting over a weekend of two days is very safe and in principle everyone can fast at home on their own, but patients suffering from serious cardiovascular diseases, mental disorders, pregnant women, especially thin and weak, and elderly people over 70 years of age, etc. should not fast. Patients suffering from skin allergies, metabolic abnormalities (such as hypertension, type 2 diabetes, coronary heart disease, etc.), digestive system diseases, etc., fasting has a better therapeutic effect on the treatment of diseases, and people with mental stress, back pain, etc., can also be appropriate. The frequency of short-term fasting is generally 1-2 times in January, even for weight loss should not be too frequent, the conditions of the crowd should closely monitor their own blood pressure, blood glucose monitoring when necessary to ensure that fasting scientific, safe and healthy.
