Grandpa Liu is 60 years old this year, he is very concerned about his physical health, every morning, he will go downstairs to the park for a walk, Tai ChiHowever, in recent times, he has found that the haze weather is very severe, which makes him feel less comfortable in his lungs.
Grandpa Liu returned home and said to his wife, Grandma Xu, "Oh, the recent smog has been so bad that I always feel uncomfortable in my lungs." ”
After hearing this, Grandma Liu thought for a while, and then said: ".I heard the old man downstairs say that eating animal blood can detoxify, you go buy some pig blood and come back, we also have to try it, detoxification
Grandpa Liu thought it was a good idea, so he immediately went to the market. He bought some fresh pig blood, and the family ate it for almost a week. However, a few days later, Grandpa Liu suddenly found himself with black stool. He was very surprised, thinking that it was a sign of detoxification, and happily told his son, Mr. Liu.
After hearing this, Mr. Liu was worried that this was not a sign of detoxification. He hurriedly took Grandpa Liu to a nearby hospital for examination. Doctor firstAccording to Grandpa Liu's black stool symptoms, he was prescribed a fecal routine and fecal occult blood testExamination results were normal.
Grandpa Liu asked the doctor: "I have black stool after eating animal blood, is my body detoxifying?"The doctor listened to Grandpa Liu's words and told him with a smile: ".Animal blood does not have a detoxifying effect. Your melena is actually caused by the oxidation of iron in the animal's blood, causing the stool to turn black. But that doesn't mean detoxification
After listening to the doctor's words, Grandpa Liu felt very disappointed. He originally thought that eating animal blood would protect his health, but in fact it did not achieve the desired effect. He realized that when facing health problems, he should seek the advice of a professional doctor instead of blindly believing rumors.
In our daily lives, we hear some rumors about the relationship between food and body detoxification. Especially this winter, some provinces of our country have encountered sandstorms. During this time, the traditional "home remedies" of "eating blood products to help clear the lungs" became popular again. Among them, there is a widely circulated saying that after eating animal blood, the black muscle excreted is detoxifying. So, is this true?
First, we need to understand what animal blood is. Animal blood is a food rich in nutrients such as protein, iron, vitamins, etc. During cooking, animal blood may turn black due to high temperatures, due to the oxidation of the iron element in it into black iron ions. Therefore, even if we do not eat animal blood, if we eat iron-rich foods such as red meat, green leafy vegetables, etc., we may have black stools.
In addition, the plasma proteins of animals are similar to human blood in composition, they are made up of blood cells and plasma, and do not produce any new substances with dust removal effects. Some people may experience black stools after consuming animal blood, but that doesn't necessarily mean they're detoxifying. It may be due to the fact that the iron in the animal's blood is not completely absorbed, or because their intestines react to certain components in the animal's blood.
However, some hold the view that "black stool" is strong evidence of porcine serum lung. Regarding this, the doctor gave an explanation: in Chinese medicine, the "food to clear the lungs" meansCertain foods can relieve symptoms related to the respiratory tract, which has a certain therapeutic effect, which is not what we usually understand as "food can remove air dust from the lungs".
Actually, this is just a guess, as there are a few other components in the blood. However, it is not directly related to the concept of "clearing the lungs".
Secondly, we need to understand the body's detoxification mechanisms. The detoxification of the body is mainly carried out through organs such as kidneys and liver. These organs filter out toxins and waste products from the blood and are excreted from the body through urine and bile. Therefore, we cannot tell if we are detoxifying by looking at the color of the bowel movements.
In addition,The vast majority of the dust and dust we inhale enters the lungs mainly through the respiratory system。Therefore, when a large amount of air is inhaled, it must first be excreted from the body through the lung channel, and then enter the gastrointestinal tract through the esophagus, and finally reach the tissues and organs of the body.
However, the ingested blood-based foods are actually digested through the digestive system. This creates a channel between blood and air – a food delivery channel. These two "channels" are actually not connectedThere is no direct link between the entry of animal blood into the digestive system and the inhalation of respiratory dust.
To date, there is no conclusive experimental or clinical evidence that small molecules in food are effective in removing dust from the lungs. Such gossip is just a beautiful fantasy in people's hearts. What we should do is:Maintain a healthy diet, eat a balanced diet, and avoid excessive intake of one food or ingredientto maintain the body's health and detoxification function.
As a traditional food, animal blood products have important nutritional value and are known as liquid meat, and are widely used in many countries and regions. Blood is a transporter of various nutrients, oxygen, and metabolites in the body. Since ancient times, people have been interested in eating blood, believing that blood is a great tonic, so what are the benefits of eating animal blood?
1) Protein supplementation
Animal blood products have a high protein content and can be used as a good protein for the human body**. For people who need to supplement protein, such as athletes, the elderly, etc., moderate consumption of animal blood products can help enhance physical fitness.
Take pig blood as an example, of which solids account for 20%, mainly protein. Protein in 100 grams of blood is about 19 grams, and others include lipids, carbohydrates, vitamins, minerals, etc. The protein content in the blood is comparable to that in beef, and higher than that of lean pork, chicken, mutton, etc, and the fat content, 100 grams of blood contains only 04 grams, only one-tenth of the lean pork.
The protein in animal blood is mainly globulin and hemoglobin, both of which are high-quality proteins, composed of 20 kinds of amino acids, of which 8 essential amino acids contain as much as 54%, which is more than 3 times higher than high-quality soy protein.
2) Prevent anemia
Animal blood products are rich in iron, with a content of up to 45 mg of iron in 100 grams of blood, andThis iron is found in the form of hemeIt is easy to absorb into the intestine, which is a key factor in iron supplementation and blood production and prevention of anemia.
Iron is one of the main components of red blood cellsIron deficiency affects the production and function of red blood cells, which can lead to anemia. Therefore, by ingesting iron-rich animal blood products, it is possible to increase iron intake, thereby preventing anemia.
Children and adolescents in the growth and development period need to eat pig blood more, because the dietary structure of children in China may lead to iron deficiency anemia and affect healthy development. About 40 per cent of children in urban areas suffer from iron deficiency anaemia, and it is higher in rural and poor areas.
Iron deficiency anemia will affect height and mental development, appropriate consumption of pig blood can supplement iron source and heme, reduce the occurrence of anemia, and also have a leading effect on children suffering from anemia.
3) Improve the body's immunity
Animal blood products contain a variety of nutrients that are beneficial to the human body, including vitamins, minerals, hemoglobin, and lipids. These substances are easily absorbed by the body and help to strengthen immunity and prevent diseases.
Animal blood products are an ideal food for the elderly. Because the elderly usually have bad teeth or fall out, difficulty in chewing, poor digestion, poor gastrointestinal peristalsis, less food, low metabolism, easy to form constipation, affecting health. It is worth noting thatBlood fiber in the blood can absorb harmful substances in the gastrointestinal tractStimulates gastrointestinal peristalsis, increases metabolism, makes bowel movements smooth, and has the function of gastrointestinal scavenger.
In addition, animal blood is made of foodnucleic acids, mucopolysaccharides and trace elements zinc, copper, chromiumIt helps the synthesis of proteins and biological enzymes, and has the effect of improving the body's immunity.
In conclusion, animal blood products, as a traditional food, are rich in nutritional value. Moderate consumption can replenish nutrients such as protein, iron and vitamins for the human body, which can help enhance physical fitness, prevent anemia and enhance immunity. However, while enjoying its delicious taste and nutrition, we also need to know some knowledge and precautions about eating animal blood.
(1) Choose high-quality animal blood
The most important thing we need to pay attention to in our daily life is to choose high-quality animal blood. We often see so-and-so hot pot restaurant or steamed vegetable restaurant in the news and newspapersFalsification of duck blood using food additivesreports. Therefore, we should choose fresh and uncontaminated animal blood from regular sources. Avoid buying expired or spoiled animal blood to avoid adverse health effects.
(2) Consume in moderation
Although animal blood is rich in a variety of nutrients,But excessive consumption can lead to certain nutrient overagesFor example, too much iron intake can lead to iron overload. Therefore, we should consume animal blood in moderation and avoid excessive intake. Generally speaking, the consumption of animal blood 1-2 times a week can meet the body's need for iron, and it is best not to exceed 100g each time.
At the same time, when cooking animal blood,Pay attention to the heat and time to avoid overcooking and loss of nutrients. Try to choose light cooking methods, such as steaming, boiling, stewing, etc., and avoid adding too many seasonings and salts to maintain the original flavor and nutrients.
(3) Beware of allergic reactions
There is a small percentage of people who have an allergic reaction to the blood of animals. Allergic reactions may manifest as itching, hives, dyspnea and other symptoms, and in severe cases, may even lead to anaphylactic shock. Therefore, if you experience the above allergic symptoms when consuming animal blood, you should stop eating it immediately to avoid subsequent adverse reactions and avoid unexpected tragedies.
Eating animal blood products does have certain benefits for the human body, such as supplementing protein, preventing anemia, and promoting metabolism. However,In the process of eating, you also need to pay attention to eating in moderation, choosing high-quality products, and paying attention to cooking methods, etc., and don't take it blindly like Grandpa Liu.
