Is it reliable to keep healthy after noon？ It should be understood as eating on time.

　　The saying "no food after noon" has been popular for many years, and many people use this method to lose weight and keep fit. Recently, however, it was reported by the media that the 29-year-old boy in Hangzhou did not eat after noon for five years. As a result, the gastric mucosa was extensively congested and eroded, with two ulcers larger than 2 cm in diameter, bleeding and brown blood scab. So, is skipping food after noon a wonderful way to keep fit or a "sharp weapon" to ruin your body? Does it conform to the law of modern life?

　　Not keeping in good health, but "practicing"

　　Not eating after noon literally means not eating after noon (11 noon to 1 pm) until dawn the next day. It originated from Buddhism. "Not eating after noon is a commandment made by the Buddha for becoming a monk, and the correct statement in the Ministry of Law is ‘ Don’t eat unless it’s time ’ 。” Dr. Wu Yichun, from the emergency department of Beijing Hospital of Traditional Chinese Medicine affiliated to Capital Medical University, said that the Buddha stipulated that there was a complete theoretical training system for not eating after noon, and its purpose was to facilitate practice, abstinence and health preservation.

　　Zhao Puchu, the former president of the Chinese Buddhist Association, also explained the reasons why monks don’t eat after noon: first, it doesn’t increase the burden of the providers, and second, it is conducive to monks’ practice.

　　Later, not eating after noon was mentioned by Yu Jiayan, a medical scientist in the late Ming and early Qing Dynasties, in "Implied Grass", especially referring to the fact that eating with blood syndrome and phlegm syndrome requires the most attention to dietary taboos. Not eating after noon should be understood as "not eating at the right time", that is, eating on time, that is, eating when it is time to eat, and not eating when it is not time to eat.

　　"Not suitable for modern life"

　　"Not eating after noon is not suitable for the life of modern people." Zuo Xiaoxia, director of the Nutrition Department of the 309 Hospital of the People’s Liberation Army, believes that there are far more pressures in modern people’s life and work than in ancient monks, so we must ensure that we can get enough energy from food every day. Moreover, there are objective individual differences between different people and different ages. The energy required by people who often sit in an office is completely different from that required by people who often do manual labor, and cannot be measured by the same standard.

　　Not eating after noon is more from the perspective of practice. As a way of keeping in good health, it should vary from person to person and should not be blindly copied. Wu Yichun said that the human body has a biological clock. At a fixed time of eating, the stomach will start to accelerate peristalsis and bile secretion will be strong. Stop eating after lunch, so that the body is in an empty stomach for a long time, and there is no food to digest, and bile and stomach acid will run idle. After idling for a long time, bile and gastric acid will have countercurrent, corrode gastric mucosa, form peptic ulcer and bile reflux. Moreover, the body has its own regulatory recognition. Being hungry for a long time will make the body respond to this behavior, strengthen the absorption rate of breakfast and Chinese food in the gastrointestinal tract, reduce the basal metabolic rate, and convert more energy into fat.

　　Health must be well-fed.

　　"Don’t eat and eat less are two concepts, you don’t confuse sth with sth else. In particular, not eating dinner has certain harm. " Wu Yichun said that skipping dinner is easy to induce hypoglycemia, especially for diabetic patients, which will lead to insufficient nutrient supply in organs and a decline in human resistance. But eating too much at dinner is also extremely bad for your health. Because the metabolic rate of human body slows down at night and the amount of exercise decreases, it is easy to cause fat accumulation and obesity, thus inducing various diseases, such as obesity, coronary heart disease and diabetes.

　　"Every day at 17: 00 — 19 o’clock is the best time for dinner. " Wu Yichun said that eating too early and getting hungry before going to bed not only affects sleep, but also affects stomach health. But you can’t eat too late, and at the latest, you should be separated from sleeping for 4 hours. This will not only leave enough time for the digestion and absorption of nutrients in the stomach, but also do some soothing exercises so that the intake of calories can be metabolized.

　　Wu Yichun said that the normal way of keeping in good health should be "moderate diet". On the one hand, diet should be moderate, that is, "starve first, but don’t make yourself full; Drink first when you are thirsty, and don’t drink too much "; On the other hand, the diet should have the concept of time. "If you are not hungry, you will feel tired, and if you are not thirsty, you will feel bloated." You can neither "eat after noon" nor "eat all the time". "Eating less and saving your body is the fundamental thing."

　　In addition to "not eating after noon", all kinds of "health tips" are now full of WeChat friends circle — — "Keep doing this every day, and you won’t catch a cold for a year", "Eat less sweets, and don’t have diabetes", "The family got cancer because of this lifestyle" and "Drinking lemon water every day can prevent cancer" … … Everything seems to be well-founded, and some even speak righteously, as if health is at risk if you don’t do it immediately, but in fact, most of them are rumors, and many health care methods have never even been heard of by doctors.

　　Three "Anything" to Identify Health Knowledge

　　Anyone who claims that a certain food can "fight cancer" is basically not credible; Anyone who sees the words "what a study has achieved in mice" will have a long mind, and a large number of "pseudo-health" posts like to take animal experiments as an example; It doesn’t make any sense to talk only about the benefits of food, not about dosage, side effects and taboos.

　　Experts remind that you should pay more attention to all kinds of "health knowledge" and think about the authenticity of these contents first, and you can also learn to master some correct knowledge in order to identify unreliable health methods. Ordinary people are very concerned about their own health, but lack certain professional judgment, so they will be fooled by some ridiculous posts and forward or try. There are still some people who only know one thing and don’t know the other, and listen to the taboos of various diets on the Internet. Therefore, before trying these "health knowledge", it is best to have a certain understanding of it. If it is really impossible to distinguish, it is best to consult relevant experts instead of trying it blindly. (Li Ying)
