Adding formaldehyde to pig blood; Pig blood contains a lot of hormones; Pig's blood contains metabolic wastes from the pig's body, so it is useless to eat more ... The debate about pig's blood is endless. People are thinking about whether eating pig's blood or other animal's blood products is really harmful to human body while eating pig's blood with tender taste. Food tells you: no!

Pig blood is rich in nutrition and is known as "liquid meat". As we all know, pig blood can "replenish blood with blood", which has a good function of enriching blood, because pig blood is rich in heme iron which is easily absorbed by human body. At the same time, it is also rich in protein, 8 kinds of amino acids and various trace elements needed by human body, and contains less fat. It can also resist aging, prevent cancer, and eliminate harmful substances in the body, so it is a "cleaner" for the human body.

After talking about so many benefits of pig blood, why are there still many "negative news" about pig blood? The reasons are summarized as follows:

Number one: Eat too much.

Although pig blood is good, you can't be greedy. Excessive consumption of pig blood may cause iron poisoning (the iron content in pig blood is 8.7mg/ 100g, while the maximum tolerable iron intake for adults is 50mg/L), and it will also affect the absorption of other minerals. At the same time, pig blood does contain a small amount of metabolic waste from the pig body, and a large amount of it will also bring a burden to the human body. Therefore, unless people with special needs, it is recommended to eat it no more than twice a week, and pay attention to a balanced, moderate and diverse diet.

The second point: the source is unknown

The blood of sick pigs must not be eaten, because the blood of sick pigs contains many substances that are toxic and harmful to human body. Moreover, some illegal farms add a lot of hormones and other chemicals to pig feed, which leads to high hormone content in pig blood. Therefore, pig blood should be purchased through formal channels, and it is best to buy the blood of primitive farmers and pigs. In addition, pig blood is large in volume, high in fluidity and easy to deteriorate. Therefore, when collecting pig blood, attention should be paid to hygiene to avoid contamination by microorganisms or other impurities. At the same time, do not eat pig blood, but should eat cooked pig blood to prevent parasitic diseases.

Whether eating pig blood or animal blood is good for human body or has certain side effects is actually a relative concept, which depends on the amount of food eaten. Let's take pig blood as an example.

Pig blood, also known as "pig red", is rich in nutritional value, because it is rich in vitamins, protein, iron, phosphorus, calcium, niacin and other nutrients. Among them, the content of protein is higher than that of lean pork we eat every day, but the proportion of amino acids is very close to that in human body, so protein in pig blood is easily absorbed by human body. Chinese medicine believes that pig blood is sweet and warm, and has the effects of detoxifying, clearing intestines, enriching blood and beautifying. Eating pig blood is good for human body.

Edible efficacy of pig blood

1, pig blood has a high iron content and exists in the form of heme iron, so it is easy to be absorbed and utilized by human body. For children, pregnant women, lactating women and other people who may be iron-deficient, animal blood can effectively prevent and treat iron-deficiency anemia, because the main nutritional components of animal blood are protein and iron, hemoglobin molecules can supplement the iron required by human hematopoiesis, and it is more easily absorbed by human body than ordinary iron ions, so it is a good "blood-enriching" food.

2. The plasma protein contained in pig blood, after being decomposed by gastric acid in human body, will produce a decomposition product of detoxification and intestine clearing, which can react with dust and harmful metal particles invading human body to promote the toxin to be excreted. The so-called eating pig blood can remove dust, which refers to this situation.

3, pig blood contains a part of vitamin K, which can promote blood coagulation, so it has hemostatic effect.

4, pig blood can also provide a variety of trace elements for the human body. People with malnutrition, kidney diseases or cardiovascular diseases, eating more pig blood is beneficial to nursed back to health, and it is obvious that it can treat dizziness, vomiting blood, injury and bleeding.

If you like to eat animal blood, go to a regular vegetable market or supermarket and choose blood products with guaranteed hygiene and quality.

But everything is too late. Pig blood is nutritious, but you can't eat it all at once! Excessive intake of protein and iron will not only waste nutrition, but also increase the metabolic burden of liver and kidney.

If you don't like to eat animal blood, meat rich in iron, animal offal, and fresh fruits and vegetables that can help iron transformation and utilization are also good choices. They can also be called "blood-enriching food". However, it is emphasized that if the symptoms of anemia are serious, don't just expect to eat something. Go to the hospital in time, find out the reason and see if you need corresponding treatment.

Tangren Health Network, a sugar control platform with temperature, welcome to pay attention and answer questions!

As a nutritionist, I often encounter this problem when I introduce the "iron triangle" (red meat, animal blood, animal viscera) of iron supplementation to you every day. I usually answer each other from the following angles:

nutritive value

iron

The above picture shows the food composition analysis of pig blood. We can clearly see that pig blood is a "low-fat, high-protein" food, and it is rich in minerals and trace elements. In particular, the iron content can reach 8.7 mg per 100 grams. For adult women who need more iron, they need to supplement 20 mg of iron every day. Pig blood is undoubtedly a good iron supplement. Moreover, because the iron in animal blood products is heme iron, it is very beneficial to digestion and absorption, and its absorption and utilization rate is also extremely high.

protein

Most of our residents' diets are mainly cereals, and protein in cereals is an important source of human body. But its lysine content is low. The content of lysine in pig blood protein is just high. When it is eaten with staple food, it can play a very good complementary role in protein-it can not only increase the dietary protein by 20%, but also increase the heme iron by 8.7 mg per100g of cereal, thus improving the nutritional density of the diet.

At the same time, pig blood also contains a variety of enzymes, vitamins, trace elements and a variety of bioactive substances. Studies have shown that pig blood has the effects of smoothing intestines, detoxifying, lowering blood pressure and resisting cancer. It can be said that it is a very nutritious food.

food safety

Most people have concerns about pig blood from the perspective of food safety. Because there is no relevant product standard about animal blood products in China, the pig blood products on the market are mixed and difficult to distinguish. The general purchase principle is: blood products purchased from regular sales channels and produced by regular manufacturers. Even if such products are not bound by a single food quality standard, at least food hygiene and quality safety are regulated by national laws and regulations. The products sold by small vendors are expensive in freshness, but there are indeed loopholes in food supervision.

Therefore, if eating pig blood products is harmful to human body? To be sure, qualified blood products have many benefits to the body.

Is eating pig blood or animal blood products harmful to human body?

Eating pig blood or animal blood products is harmless to human body, but avoid excessive consumption, otherwise it will easily lead to iron poisoning and bring a burden to human body. Doctors suggest that you should not eat pig blood more than twice a week, and it is best to buy it in a regular supermarket.

The benefits of eating pig blood

1, blood. Pig blood contains high iron content, which can prevent and treat iron deficiency anemia. Children in growth and development and pregnant or lactating women can eat more.

2, anti-aging. Polyphosphates in pig blood can improve people's memory, and people with early Alzheimer's disease can eat more;

3. Detoxification. Protein in pig blood can be decomposed by gastric acid and digestive juice, which can produce a kind of disinfectant and intestinal moistening substance. This substance can be combined with particles and dust invading the human body, so that they are not easily absorbed by the human body and discharged through feces.

4. Anti-cancer. Pig blood contains cobalt, which can prevent the growth of malignant tumors and has the effect of preventing cancer.

5. Prevent cardiovascular diseases. Pig blood contains a variety of trace elements, which can effectively prevent coronary heart disease and arteriosclerosis in middle-aged and elderly people.

Taboo population of pig blood

Suitable crowd

1, for people who are healthy and peaceful, they can eat pig blood and have a good tonic effect on the body.

2. Because pig blood is rich in iron, anemia patients can eat it properly, which can alleviate anemia symptoms.

3. Pig blood, also known as the scavenger of human body, is suitable for the elderly, women and people engaged in dust, sanitation, textile and excavation.

4. Patients with blood deficiency, dizziness, intestinal parasites, abdominal distension and other symptoms can also be properly eaten, which can effectively alleviate the symptoms.

Taboo crowd

1, hypercholesterolemia, liver disease, hypertension, coronary heart disease patients should not eat.

2. It is not suitable for people suffering from certain diseases or bleeding symptoms.

Pig blood or animal blood products are harmless in themselves, and there are many trace elements needed by human body, but the source of food is unknown now. First of all, we don't know what these animals are raised with. Secondly, we don't know what blood products are added in the production process, so we can only resign ourselves to fate. I heard a joke that an aunt went to the market to buy a pig leg bone and went home to cook soup to supplement calcium for her son. The ghost said beside her, Don't bother, aunt, I have only lived for three months, and I am still short of calcium than your son.

Some people think that animal blood can not only supplement iron and blood, but also prevent and treat dust and other dirt in the lungs.

For the former, animal blood and its products and pig liver have the best effect in food, and can also supplement high-quality protein. For the latter, it is definitely useless, and it has some effect on the stomach.

However, the counterfeit products made of blood and blood powder on the market now account for a large proportion, so we should pay attention to identification, otherwise, it will not only be useless, but also do a lot of harm.

Animal blood contains high cholesterol, so patients with cardiovascular and cerebrovascular diseases should not eat more.

There are many reasons for anemia (this does not include malignant, megaloblastic, aplastic anemia, etc.), besides the influence of iron and tannic acid in food, it is also influenced by parasites, gastrointestinal function, hemorrhagic diseases and so on.

Children and premenopausal women are prone to iron deficiency anemia. Adult men are not easy to lack iron unless they suffer from hemorrhagic diseases such as severe hemorrhoids.

Thank Yao Ma for her invitation. If the human body is anemic, animal blood-pig blood can be supplemented appropriately, provided that there is no bacterial pollution and it is not a disease. Tofu cooked with pig blood is very delicious, but duck blood tastes better than pig blood. Jinling duck blood vermicelli soup is better, delicious and famous in China. You don't have to be serious about any food, just eat it if you want, stop studying, be healthy and maintain, don't overeat, don't eat too much food, just let nature take its course, give priority to exercise, don't mind, so you can't eat it; Eating like that is bad for your health, living with meat and vegetables, and eating more fruits will keep you alive to a hundred years old.

To sum up, pig blood is a high-protein and low-fat food, which can not only provide high-quality protein for human body, but also prevent and treat iron deficiency anemia, and is a popular tonic. However, the most critical issue of eating pig blood and other blood products is food safety, especially some packaged blood products, which is difficult to judge whether it is hygienic and safe. I suggest you go to large shopping malls to buy fresh blood. After all, the food safety control in large shopping malls can be more strict, and we can eat with confidence. In addition, friends with diarrhea should try not to eat pig blood, because blood has the effect of relaxing bowels and avoiding aggravating diarrhea. Finally, I recommend several small recipes for pig blood.

Women are prone to anemia, a bottle of blood will make them dizzy, weak, yellow, and some serious, dizzy and faint. Anemia eating animal blood products also has a certain blood-enriching effect. Animals themselves suffer from some other infectious diseases. So we must pay attention to sterilization and disinfection when eating animal blood products. Like the most in our daily life is pig blood. Every part of the pig can be eaten. Pig blood makes it into a blood clot, and then it can be taken after being cooked. The blood-enriching effect of bleeding is particularly good. The price is also affordable. The nutrient content of duck blood is also high, but the duck blood of a duck is pitiful, so the price of learning will be relatively much higher. Yang Xue is most suitable for children, pregnant women and lactating mothers, because this kind of people use the most blood, and the nutrients in duck blood just supplement their bodies. Chicken blood and cow blood are the same, their blood is flat and suitable for everyone.

When I was a child, I killed pigs. At that time, there was no slaughterhouse. I killed them at home first. At that time, no one went to collect pig blood or anything. Generally, farmers wait for it themselves, then cook a large pot full, a large farmer's iron pot with a diameter of more than one meter, and add some Philippine food. All of a sudden, most of the village is full of fragrance. Then we pack a bowl of bowls and send it to every household. This is our habit of killing pigs, which is the same in the whole village. When that pig is killed, it will send a bowl to the neighbors. In the past difficult years, it was also a rare disorientation, and the spirit of helping each other among the township leaders. Although it's nothing now, the past will always be inadvertently remembered, full of happy memories.

In modern science, it is found that pig blood or animal blood products have high nutritional content. Rich in iron, blood protein, various trace elements, etc., eating pig blood properly can also detoxify the body, expel dust and relax the bowels. But also good cooking ingredients, such as: pig blood sausage, sour blood duck, hairy blood curd, hot pot blood slices and so on. It has become a signature dish in many restaurants, attracting diners to move their forefinger and appetite, adding bricks and tiles to the weight of [spreading their hands] [covering their faces] [covering their faces].

Pig blood and blood products themselves are generally not harmful, and improper eating and excessive eating may have certain effects, such as: pig blood is not cooked enough, and it turns red after being cooked in time. For example, antler blood is drunk [yi tooth] [yi tooth] [yi tooth]. This will do some harm to the body.

In addition, many domestic animals and poultry are now raised centrally, and antibiotics and obesity hormones are given more. These animals should eat as little blood as possible. There are also some artificial blood products prepared by black-hearted vendors. It's all made of pigments and chemicals, which are harmful if eaten. We pay attention to observation and comparison:

1. It is better to watch the color of blood products, and the color is naturally free of impurities; Dark color, no natural luster, and more impurities are not good.

2. smell. Smell the blood products. Good blood products smell fishy, but they don't choke the nose, have no smell of necrosis, and even valuable products such as antler blood have a faint scent. On the contrary, if you smell a foul smell and necrosis, you must not eat it. In particular, some livestock ready to die of illness have a particularly unpleasant smell.

3. cut. Cut the blood products into pieces, and the good blood products should be cut into pieces, tender and appropriate, and the hands should be broken, and should be handled with care; Poor blood products, which are thick and hard to cut, are like falling dust when touched, or will not break when rolled up.

Step 4 cook. Cooking blood products. After a good blood product is cooked, its luster is natural, its taste is tender and smooth, and it is very enjoyable to eat; Poor blood products have dim color and poor taste, like stirring wax, or have little change after cooking. Cooked for a long time is not rotten or old.

At present, we should keep our eyes open and distinguish between good and bad food. Health is the capital of revolution. Good health can make you enjoy more delicious food. How do you eat blood products? Welcome to the message area to exchange [yi tooth] [yi tooth] [yi tooth]. I look forward to your participation [prayer] [prayer] [prayer].
