In recent years, with the development of industrialization, environmental pollution has become increasingly serious. 20 13 put forward the new term PM2.5, and many people thought of "eating" to solve this health problem. Pig blood once became the darling of people, and the saying that eating pig blood can remove harmful substances from the lungs is also highly sought after. [2]
So, is this statement true? The Chinese teacher will answer you today.
Can pig blood "clear lung"?
We often talk about pig blood, which refers to the blood clot formed by people dropping pig blood in pots or some containers and boiling it in boiling water, also called blood tofu. The main components of blood tofu are water 79%, protein 18.9%, fat 0.4%, carbohydrate 0. 1% and a small amount of inorganic salts and minerals. After pig blood is eaten by people, the above nutrients are decomposed and absorbed in the digestive system, and other components are excreted together with other food residues in the form of feces. The dust in the lungs mainly enters the lungs through human breath, and there is no chance to meet the pig blood eaten in the digestive system, so it is impossible to remove the waste from the lungs.
Although it has been circulating that eating animal blood products can "clear the lungs", there is no clinical basis to prove it. [5] Current studies have proved that fine particles such as PM2.5 are difficult to be removed by human body after entering alveoli, which will increase the level of oxidative stress and inflammation [2-4].
So eating pig blood can't remove harmful substances from the lungs.
The lungs of the earth and our lungs need our love.
Living in the same land, we can choose to breathe the same air, but when the air quality is poor, we can reduce the dust inhalation by physical methods, such as avoiding outdoor sports as much as possible in foggy days, wearing a mask when going out, washing your face in time and exposing your skin after going out. [6] But it is more important for everyone to participate in a low-carbon life, so as to reduce pollutant emissions and improve our living environment. Protecting the "lungs" of the earth is also protecting our lungs.

It is often seen on the internet that eating pig blood can remove harmful substances from the lungs, and it is also said that people who work in a dusty environment can remove dust from the lungs by eating more pig blood. I need to clarify this statement. This is a rumor, not credible. Why do you say that? Below, I will give you an analysis.
First of all, pig blood becomes delicious food after it is cooked. When we eat it, it will be liked and absorbed by our gastrointestinal tract. In this process, most substances in pig blood will be digested and absorbed by human body, especially protein, amino acids and iron, which are rich in pig blood, will be absorbed by human body for our needs.
In addition, pig blood also has the function of moistening intestines and relaxing bowels, which can effectively discharge and remove the silt and dirt in the intestines, promote the discharge of some dust and metal particles in the intestines, and play the role of moistening intestines and relaxing bowels.
But we must look at the situation here. This pig blood reacts in the gastrointestinal tract from beginning to end. Even if it has the function of removing harmful substances, it also removes harmful substances in the intestine. Our gastrointestinal tract and lungs are not connected. How does it go to the lungs to remove harmful substances from the lungs? Moreover, pig blood is digested and absorbed through the gastrointestinal tract, and at most some nutrients flow through the lungs with the flow of blood, but these nutrients have no effect on removing harmful substances from the lungs.
Many people may ask, doesn't Chinese medicine say that pig blood has the effect of clearing lung heat? Yes, Chinese medicine says that pig blood has the function of clearing lung, but this clearing lung is not to clear harmful substances in the lung, but to clear lung heat, which has a certain effect on the disease of lung injury caused by heat toxin.
In addition, some people will ask, then we will have black stool after eating pig blood. Are those black substances toxic in the intestines?
In fact, we all have black stool after eating pig blood, because the pig blood we eat contains a lot of red blood cells, which contain a lot of hemoglobin, and hemoglobin contains a lot of iron. When our intestines digest and absorb pig blood, they will absorb some iron, but most of the iron in pig blood cannot be completely absorbed by human body, so the iron in pig blood will react with some sulfides in the intestines and become black ferrous sulfide, and then these ferrous sulfides will be mixed with feces to form black feces. Therefore, this is not a harmful substance in the intestine.
Of course, some harmful substances in the intestine will still be discharged together with these black stools. We often eat pig blood, which can not only relieve constipation, but also improve iron deficiency anemia. Therefore, for some patients with constipation and some patients with iron deficiency anemia, we can eat more pig blood in daily life and improve symptoms through the role of diet.
Message from the author: I am very happy to give you the knowledge of popular science and health. I am a left-handed doctor. I give you the knowledge of popular science and medicine in simple language every day. Codewords are not easy. If you like my article, please give me a compliment! If you have any questions, you can leave a message in the comments section. Welcome to pay attention and forward. Thank you for your support! Eating pig blood can clear the lungs. Maybe we've all heard this sentence. Especially some middle-aged and elderly people who are keen on keeping in good health always feel that diet is the most important way to keep in good health. It is undeniable that diet is very important, but the problem is that many times, the efficacy of food is exaggerated.
Can eating pig blood remove harmful substances from the lungs? Eating pig blood to clear lung is not groundless. Any statement about the efficacy of food must have a source, and then spread to ten words. The fact that pig blood can clear the lungs is infinitely exaggerated and becomes a well-known fact. There are several theories about the original source of "pig blood clearing lung".
Eating pig blood can clear the lungs. Is it reliable? The first argument is that a long time ago, some people who worked in coal mines and stone powder factories for a long time and were exposed to dust, asbestos and harmful gases were always worried that they would get pneumoconiosis, tuberculosis and other diseases. As the wife of the factory, in order to stabilize the mood of the workers and continue to work, she lied that eating pig blood can remove harmful substances from the lungs. Some workers found that the stool was really black after eating pig blood, so they believed the fact that pig blood cleared the lungs.
Black stool after eating pig's blood is not the effect of clearing lung and detoxifying. This is because the main component of pig blood is red blood cells, which contain heme, so it contains a lot of iron. If iron is not completely absorbed in the body and combined with the ingested sulfur, black iron sulfide will be generated under the induction of internal environment, and in this case, black stool will be formed.
The second argument is that eating pig blood to clear the lungs is a confusion of the concept of traditional Chinese medicine. Clearing lung heat is a concept of traditional Chinese medicine. In fact, it is not what we call "clearing away harmful substances in the lungs", but the meaning of "clearing away lung heat". Traditional Chinese medicine generally says that nourishing yin and clearing lung is a method to treat lung heat and yin deficiency. It is mostly used for patients whose clinical symptoms are dry cough, scanty phlegm, dry throat and hemoptysis, cough and asthma, dry nose and dry lips, mainly nourishing yin fluid and clearing lung heat. In other words, clearing lung is not clearing lung. Therefore, it is not reliable to eat pig blood to clear the lungs.
What are the benefits of eating pig blood? The real benefit of pig blood is not to clean up the harmful substances in the lungs. Pig blood is rich in various nutrients, and the iron content is 18 times higher than that of eggs, so the iron in pig blood is more easily absorbed and utilized by human body. Therefore, the biggest role of pig blood is actually to enrich blood.
Especially for women, eating pig blood often can effectively supplement iron, prevent iron deficiency anemia and make people refreshed. In addition, it is also suitable for children, pregnant women and anemia patients, and can prevent and correct iron deficiency anemia. Protein, which is rich in pig blood, belongs to high-quality protein, which can not only enrich blood, but also supplement protein's food. In addition, studies have proved that trace elements such as zinc and copper contained in pig blood can improve immunity and resist aging, and the elderly can delay aging if they eat them often. Lecithin contained in it is helpful to delay the development of atherosclerosis, prevent cardiovascular and cerebrovascular diseases, prevent and treat Alzheimer's disease and stop bleeding.
It should be noted that there are some artificial pig blood on the market at present, so we should be careful when selecting it, and we should distinguish the color, section and smell. In addition, pig blood should not be eaten with soybean, rehmannia glutinosa, kelp, Polygonum multiflorum Thunb, almond and other ingredients, so attention should be paid to avoid it. Moreover, pig blood contains some metabolic wastes and cannot be eaten in large quantities. It is suitable for patients with hyperlipidemia, fatty liver and gastrointestinal diseases. Try to avoid eating.

In addition, if your family also has troubles related to eating pig blood, please pass this article on to them! Eating pig blood can clear the dust from the lungs.
I can't. People in China often say "what you eat supplements what you eat", which is a rather primitive and simple concept. Anything that can be swallowed must be degraded in the digestive system and become a small molecular compound acceptable to the blood before it can be further absorbed and converted into other substances. Pig blood is also degraded in the human digestive system and has no effect on any harmful substances in the lungs. If there is inflammation in the lungs, the only way that humans can solve it at present is to use antibiotics.
There is a saying in the countryside that eating children with blood deficiency who are often exposed to dust has the effect of clearing away lung heat, but if you think about it carefully, it makes sense and has no scientific basis. Harmful substances in the lungs are residual substances inhaled by people. People who eat blood-enriching children are excreted through digestion, only into the stomach, not into the lungs, and do not touch.
In real life, whether smoking or doing dusty work, our lungs will be deeply damaged. Once we have difficulty breathing or other problems, we always think of eating pig blood at the first time, always thinking that eating pig blood can clear the lungs. In fact, this statement is completely groundless and nonsense. Next, through this question and answer, I will talk about my views on the problem that eating pig blood can clear the lungs.
The general introduction of pig blood is also called "blood tofu" in the mouth of ordinary people. Eating with tofu is a delicious dish. In real life, after pigs are slaughtered in slaughterhouses, the released pig blood will be heated and made into a gel state. Only in this way, when we eat pig blood, we will feel that pig blood is solid, most nutrients will not be lost, and it is fresh and delicious.
Pig blood is rich in nutrients, such as iron, phosphorus, calcium, vitamin B2, vitamin C and protein, especially iron. In order to study the iron content of pig blood, the relevant personnel tested the fresh pig blood and found that the iron content of 100g pig blood was 40mg. More importantly, our human body has a good absorption rate of iron in pig blood. Because of this, it is the "king of enriching blood" in the eyes of our people.
Judging from the rich nutrition of pig blood, pig blood is indeed a high-quality food. It is recorded in Compendium of Materia Medica, a famous Chinese medicine book in ancient China: "Pig blood is salty and flat, and it can produce blood." Both ancient medical books and existing scientific research have given high evaluation to pig blood. Because of this, many people will excessively "myth" the efficacy of pig blood and desperately eat pig blood. But doing so will only bring harm to health.
Can pig blood really clear the lungs? If pig blood can enrich blood, it is definitely more credible than pig blood clearing lung. If pig blood can remove toxic substances from the lungs, it must be related to the plasma protein in pig blood. We eat pig blood, which enters the stomach through the esophagus, and under the digestion and decomposition of the stomach, it will form detoxification substances.
Detoxifying substances are formed in the stomach, which will detoxify the intestines and then excrete them with feces. Based on this, pig blood can only clear the intestines, and has no cleaning effect on toxins, dust and other substances in the lungs.
Why do you say that? The food we eat, sometimes a piece of lean meat, is swallowed without being fully chewed. At this time, our stomach will digest and decompose large pieces of meat into small molecular substances, such as protein and sugar. It is used by whole body cells through intestinal-hepatic circulation. If we eat pig blood, the pig blood is decomposed into useful substances for the whole body by the digestive tract, and the remaining residue will remain in the intestine, so how to clean up the toxic substances in the lungs? So from this point of view, food can sometimes moisten the intestines and clear the intestines, which we can all understand, but when it comes to "clearing the lungs", it is no good.
Although pig blood is rich in nutrition, sometimes it should be eaten safely. I have talked about the benefits of pig blood in detail above, but with the increase in the cost of preparation and storage of pig blood, many unscrupulous merchants have taken a fancy to the general public's favor of pig blood, and often use some dirty behaviors to treat pig blood, such as using formaldehyde to coagulate pig blood and form a delicate taste, which is very harmful to our health. So, here I want to talk about how to eat pig blood safely. In fact, it is mainly "seeing, touching and smelling".
Finally, to sum up, there are many sayings about pig blood clearing lung in real life. We should believe in science and eat pig blood from a scientific point of view. You can't say that pig blood is good, so you overeat it. In fact, this is also very bad for health.
I want to say whether pig blood can remove harmful substances from the lungs, which must be said at different levels. I wonder if Chinese medicine believes that pig blood can clear lung. But modern medicine does not claim that pig blood can clear lung. Check the literature about pig blood. Let me talk about some beneficial effects of pig blood.
Pig blood is very nutritious and is called "liquid meat" and "tofu blood". According to the determination, the content of protein per gram of pig blood is higher than that of protein in beef and lean pork, and it is easily digested and absorbed by human body. Another feature of pig blood is that its fat content is very low, only grams per 100 grams. It is lean pork, which is a low-calorie and low-fat food.
In addition, pig blood also contains mineral salts and various rich minerals, such as iron, calcium, phosphorus, potassium, zinc, copper and manganese. In particular, the content of iron is extremely high, reaching 0/00g mg per kloc, which is higher than that of pork liver, eggs and lean pork. Iron is an important raw material for human body to make blood. If it is iron deficiency anemia caused by iron deficiency, there will be symptoms such as complexion, fatigue, dizziness and tinnitus. At this time, patients often eat pig blood can play a role in enriching blood.
Modern medicine has proved that trace elements such as zinc and copper in pig blood can improve immune function and delay aging. Pig blood also contains a certain amount of lecithin, which can inhibit the harmful effects of low-density lipoprotein and help prevent atherosclerosis. It is an ideal food for the elderly and patients with coronary heart disease, hyperlipidemia and cardiovascular and cerebrovascular diseases. It is also good for preventing and treating dementia, hypomnesia, forgetfulness, insomnia and dreaminess.
In addition, pig blood also has the function of clearing the intestines and relaxing bowels. The plasma protein in pig blood is digested and decomposed in the intestine, and the undigested residue will absorb a lot of water, as well as harmful substances in the intestine, such as metal particles and dust mixed in food and excreted with feces.
Can eating pig blood remove harmful substances from the lungs? It can be said that today, let's refute the rumor. In the face of problems and rumors, you only need to know the main points: smoke enters the respiratory tract, and dishes made of pig blood enter the digestive tract. The path is completely out of range. Do you think it can be cured? For the therapeutic effect, there is no effect. Pig blood can't prevent smoke from entering the human body. But for this rumor, most people would rather believe what they have.
Now let's have a look. Our fear of smoke comes from the harm that smoke inhaled into the lungs may do to our bodies.
We know that PM 2.5 is very dangerous. For example, it contains many harmful substances, such as benzopyrene, heavy metals, pathogenic microorganisms and so on. The key is that their diameter is less than 5 microns. This small suspended particle can directly enter bronchioles and alveoli without any difficulty. When these particles enter the alveoli, they will cause local inflammation in the lungs. In addition, it can also enter the blood system, thus damaging other body organs, such as the heart and central nervous system.
Without any protection, smoke will directly enter our bodies, which is why we are afraid.
Another point is that people's understanding of lung clearance is at different levels. For example, clearing the lung mentioned by Chinese medicine means expelling lung heat. For "phlegm-heat blocking lung collaterals", it is necessary to clear lung. The purpose of clearing lung heat here is to eliminate lung heat, not to clear lung heat. Toxins.
So much food, why choose pig blood? There is a written record of pig blood in Compendium of Materia Medica: pig blood tastes salty and delicious. It can produce blood, malaria, stroke, bruises, fractures, headaches and dizziness. Pig blood can also inhibit stones and detoxify. In addition, lecithin in pig blood also has a certain inhibitory effect on cholesterol. If your family suffers from hypertension, coronary heart disease, hyperlipidemia and cerebrovascular diseases, you can eat some pig blood appropriately. However, this is not the same as stealing the concept. Pig blood has the function of clearing away lung heat, and there is no written record or scientific conclusion.
You may ask, the stool is black after eating pig blood. Will this excrete toxins from the body? It's not the same thing. Pig blood and other animal blood are rich in iron. The human body can only absorb some iron, and the other part can't. After entering the intestine, it combines with the sulfide in the intestine to form ferrous sulfide. Therefore, the dark unknown thing is not toxin but ferrous sulfide.
However, even if pig blood can't clear the lungs, it can't stop loving it. Pig blood is very suitable for stewing, such as frying pig blood. The method is simple: heat the oil pan, add onion and ginger to stir fry until fragrant, add pig blood together, stir fry until it changes color, and finally add cooking wine, soy sauce, sugar and salt. Can cook, spicy and soft, is a typical dinner dish, a bowl of pig blood can definitely kill two bowls of rice, full.

Now the air pollution is getting worse and worse, and there are more and more foggy weather. People usually think that eating foods that clear the lungs, such as pig blood, can effectively remove the dust inhaled into the lungs. So can eating pig blood really remove the dust from the lungs?
1 What's in pig blood?
Pig blood is mainly composed of blood cells and plasma. Every 100g pig blood contains 0.9g of carbohydrate, 0.30g of fat, 8.70mg of iron, 4mg of calcium and 0.28mg of zinc, and protein 12.20g ..
Can eating pig blood remove lung dust?
It is a rumor that people are popular to eat pig blood for dust removal. It comes from the tarry black stool after eating pig blood, which seems to discharge the dust in the body. In fact, it is hemoglobin in pig blood, which contains a lot of iron. If it is not completely absorbed, it will combine with sulfide under the action of gastric acid and intestinal bacteria to form black iron sulfide, which will make the stool black.
3 the reason why eating pig blood can't clear the lungs
Because pig blood is absorbed by human body through digestive tract, and dust in the air enters the body through respiratory tract, pig blood has no ability to pass through digestive tract to absorb dust in respiratory tract. After hemoglobin in pig blood is absorbed by human body, it will not produce substances with dust removal function.
What are the hazards of dust inhalation in the lungs?
There are many suspended particles in the air in foggy days, but not all dust can be inhaled into the lungs. The harm of suspended particles with different diameters to our human body is different.
Diameter 10 um (the diameter of a hair is about 50 70 um).
Basically, it will not be inhaled into the body, but will be excreted with nasal mucus and sneezing, which has little effect on the human body.
5 micron diameter 10 micron
5 10 um suspended particles are mainly inhaled into the airway and can be excreted through coughing and expectoration, which is harmless to human health.
Suspended particles with a diameter of 5 um will enter bronchioles and alveoli, especially particles with an aerodynamic diameter of less than or equal to 2.5 um, that is, PM 2.5, which can almost completely enter alveoli.
PM 2.5 is a carrier of a large number of harmful substances, which will cause local inflammation in the lungs after being inhaled into alveoli, and then damage the lungs. It can also enter the blood through the alveolar capillary barrier, further damaging the heart and central nervous system, which is very harmful to health.
The most effective way to avoid this situation is to wear a mask when going out in foggy weather.
Generally speaking, it can clear the intestines. Clearing lung depends on aerobic exercise to increase vital capacity and activate seldom used alveoli. It seems that black fungus can clear the lungs. This is probably taken for granted. It is the same as washing blood vessels with fungus. In fact, there are many functional differences between these two things besides color. Can't lotus root starch and Ge Fen wash out lung blood vessels? If you want to restore the vitality of the lungs and eliminate the adsorbed toxins, you must speed up the blood circulation there. Eating alone doesn't help much
