In recent years, many businesses have been instilling a concept into consumers: acidic constitution is the source of all diseases, and they believe that acidic body fluids will lead to decreased immunity and susceptibility to colds and other infectious diseases. As a result, some health foods promote the effect of acid excretion, and some beauty salons even launched the "seaweed acid excretion" project. However, experts of traditional Chinese and western medicine have refuted this, because the medical profession holds that acidic constitution is the most healthy from the basic point of view that the pH value of human body fluids is in a weak alkaline state of 7.35 ~ 7.45, but most people's body fluids are below 7.35 due to the influence of living habits and environment, and their bodies are in a sub-health state between health and disease. These people are acidic constitutions. Chinese and western medicine refute the popular saying that "acid constitution is the root of illness", and both western medicine and Chinese medicine experts fundamentally deny the saying that there is no such thing as "acid-base constitution" in the medical field at present. Expert opinion Su Mingshan, deputy chief physician of dermatology of Beijing Zhongguancun Hospital, and Dong Xingyun, deputy chief physician of gastroenterology of the First Affiliated Hospital of Tsinghua University, said that acid-containing metabolites (carbonic acid, lactic acid, etc.) and alkaline products are inevitably produced in the body during life activities. However, the human body has three regulating systems that can balance acid and alkali. The kidneys can excrete excess organic acids through urine, and many acidic components will be rapidly excreted through breathing. Body fluids will also neutralize the acid-base balance. Therefore, the PH value of body fluids of normal organisms is always stable within a certain range, so the human body's constitution will not be acidic. Yin Zhichao, a researcher at China Academy of Traditional Chinese Medicine, also said that there is no such thing as "acid-base constitution" in traditional Chinese medicine. It can only be said that the human body may have symptoms of "yin deficiency" after ingesting too many acidic substances, such as deficiency heat, night sweats, and drowsiness. However, not all of these symptoms are caused by acidity. Clinical viewpoint In fact, there is an untenable logical problem in the concept of acidic constitution, that is, acidic constitution is the source of all diseases. In medical clinic, there are indeed many cases of acidosis. However, it is not acidosis that causes disease, but because of taking certain drugs or getting sick, acidosis will occur. Some common diseases, such as diarrhea, renal failure and metabolic diseases, such as diabetes, do cause acidosis. But the inducement of these diseases has nothing to do with acidosis. Being alkaline in the body is healthy, but it is actually just a wrong proposition of acidic physique theorists to steal the concept. Take Liang Shuanglin's theory, which is known as China's earliest concept of acidic constitution, as an example. They emphasize that the PH value of the body should always be at 7.4. In fact, this is nonsense, because the pH value of normal people's blood is about 7.4. Moreover, not every part of the body is alkaline. There are several places in the human body that must be sour to be healthy. The first one is the stomach, which goes without saying that everyone will know more or less. If vomiting occurs, a large amount of gastric acid will be eliminated from the body, but it will cause mild alkalosis, which is the reason why you will feel dizzy after vomiting. The other is the skin. The pH value of healthy skin should be 5.5, and the skin with weak acidity is less likely to breed bacteria. The ideal environment for women's vagina is also acidic. Once the pH value is greater than 4.5, it will cause inflammation. In addition, human normal urine is also acidic. An important function of the kidney is to expel acidic substances from the urine. If a person's urine is alkaline, it is unhealthy. If according to the theory of acidic constitution, a person's body fluid or blood pH value is alkaline to be healthy, then it is logical that skin, stomach, vagina and urine should also be alkaline. Objectively evaluating the theory of acid constitution is like a lie with holes everywhere, and a lie needs another bigger lie to fill the hole. In fact, they are also trying to fill this hole. Although they can't prove that there has been any new research discovery, which medical journal recognized by the world medical community published the paper, they also cited an example that Otto Heinrich Warburg (warburg), winner of the 193 1 year Nobel Prize in Medicine, supported the acid theory. Acidic Constitutionalists say that the Nobel Prize winner in medicine mentioned that under hypoxia, the body is acidic, which is the root of cancer. As it turns out, in all the public works of this German biochemist, there is no research involving acidic constitution or acidosis, and there is no evidence that hypoxia is related to the acidity of the body. Liang Shuanglin, who claimed to be the first to put forward acidic constitution, revealed in an interview that he put forward this concept in 200 1 year. I don't know how nutritionists in China who are trying their best to promote the pathogenic theory of acidic constitution can successfully carry out a soul dialogue through time and space and life and death. As for the American Nobel Laureate Ryan they mentioned, Professor Zhang Jian, who has been immersed in the American medical field for more than ten years, has no impression at all, let alone using Google or Baidu to search. The so-called "acidic constitution theory" is a pseudo-scientific theory that has been widely circulated in recent years. This theory holds that the acidification of constitution is the source of all diseases, whether it is cancer or common hypertension, diabetes, gout, etc., it is caused by eating too much "acidic food", and the so-called "acidic food" is so common that it can definitely scare you: fish, meat, rice. In particular, rice, the staple food of China people, has been rendered as a typical representative of "acidic food", which has become the chief culprit of the disease, which can almost cause panic in the whole society. Anyone who understands this theory is almost afraid of himself. If people really believe this theory and guide their daily diet according to this theory, it will really do great harm to their health. In fact, the so-called "acidic constitution" can cause disease, which is purely playing with the concept. According to Liang Moumou, who is said to be the first to throw out the theory of "acidic constitution", the pH value of human body must be maintained at around 7.4. In a sense, this is true, but it is nonsense, because normal human body fluids are weakly alkaline, and the pH value is around 7.4. In daily life, you don't have the ability to make it 6.8, even if you eat so-called acidic food every day! Because human body fluids have a strong neutralizing and buffering function, he can maintain the balance of pH, so no matter whether the food you eat is acidic or alkaline, the pH value of the human body is basically unchanged, and there is no so-called "acidic constitution", which has been mentioned in middle school textbooks. Some people believe in the "acid constitution theory", I think it may be because many people have heard of the saying of "acidosis", but in fact it is the result of some serious diseases, not caused by diet for no reason. This is a typical "fruit-taking cause"! Moreover, by the way, besides "acidosis", there are also concepts such as "alkalosis" and "water poisoning" in medicine. When these concepts reach some swindlers who like to create sensational lies, I don't know what kind of associations they will cause, thus creating even more earth-shattering fallacies. In fact, many famous experts and scholars at home and abroad have also criticized the theory of acidic constitution. For example, Zhang Jian, a Chinese scientist at the Arizona Cancer Research Center in the United States, has demonstrated it in many ways and discussed it with his American counterparts. Finally, he said that he can responsibly say on behalf of the experts at the American Cancer Research Center that acidic constitution is a created concept, which is purely false! If someone is superstitious about "acidic constitution theory", it is not only useless but also harmful. Because if a person is influenced by the theory of "acidic constitution" and arranges his diet strictly according to the alkaline recipe put forward by the theory, it will inevitably lead to nutritional imbalance over a long period of time, which may lead to illness, because the human body must balance all kinds of nutrients in order to maintain a healthy constitution. How does editing this paragraph change acidic constitution? 1, don't stay up late: If you don't sleep after 1 in the morning, the energy needed for human metabolism is not supplied by the food you eat, but is completely supported by various hormones secreted by the body. At this time, endocrine metabolism will produce many toxins, which will make the body fluid environment sour. 2, do not eat midnight snack: usually eat after 8 pm is called midnight snack. Because the metabolic capacity of the human body will be reduced at night, and many organs have entered a state of rest, it will cause food to stay in the gastrointestinal system, gradually become sour, ferment, and produce toxins, which will make the body sour. 3, eat breakfast: At 4: 30 in the morning, the body temperature will reach the lowest point of the day, and the speed of blood circulation is also the slowest at this time. If you sleep too late and don't eat breakfast, the human body will not get enough energy supplement, and the speed of blood circulation will become slower, making the human body in a state of hypoxia and getting worse. 4. Eat more coarse grains: Exquisite food will accelerate the aging of the gastrointestinal tract. Although many people now know the benefits of coarse grains, it is still a little far from coarse grains for office workers who lack exercise. Eating exquisite food for a long time will accelerate the aging and decline of gastrointestinal function, and constipation will often occur, which will cause the food they eat to become toxic substances harmful to the human body and gradually deteriorate their physique. 5. Take in the right proportion of acidic and alkaline foods: The human body contains about 80% alkaline substances and 20% acidic substances, so the healthiest way to eat is to take in 80% alkaline foods and 20% acidic foods, of which 80% alkaline foods are composed of 60% vegetables and 20% fruits, while 20% acidic foods are protein and starch.
