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

Adding formaldehyde into pig blood; Pig blood contains a lot of hormones; Pig blood contains metabolic waste in pigs, and it is useless to eat too much ... There are endless arguments about pig blood. While eating fresh and tender pig blood, people are also thinking about whether eating pig blood or other animal blood products is really harmful to human body. 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 effect of enriching blood, because pig blood is rich in heme iron which is easily absorbed by human body. At the same time, it is 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 so much about the 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, it 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 in pigs, and a large intake will also bring a burden to the human body. Therefore, unless people with special needs, it is recommended to eat 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 a high level of hormones in pig blood. Therefore, pig blood should be purchased through formal channels, preferably from primitive farmers and pigs. In addition, pig blood is large in volume, high in fluidity and easy to deteriorate. Therefore, attention should be paid to hygiene when collecting pig blood to avoid being contaminated 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 some side effects is actually a relative concept, depending on the amount of food eaten. Let's take pig blood as an example.

Pig blood, also known as "pig blood", is rich in nutritional value, because it is rich in vitamins, protein, iron, phosphorus, calcium, nicotinic acid and other nutrients. 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 of 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 contains high iron, which exists in the form of heme iron and is easily 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, and hemoglobin molecules can supplement the iron needed by the human body for hematopoiesis, which is more easily absorbed by the 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 detoxifying and clearing intestines, which can react with dust and harmful metal particles invading human body and promote the excretion of toxins. The so-called 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 disease or cardiovascular disease, eating more pig blood is conducive to aftercare, and has obvious therapeutic effects on dizziness, vomiting blood, trauma 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 it's 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. It can also be called "blood-enriching food". But 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 and 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 kind of food with low fat and high protein, and it is rich in minerals and trace elements. In particular, the content of iron can reach 8.7 mg100g. 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 Chinese residents' diets are mainly cereals, and protein in cereals is an important source of human body. But its lysine content is low. The lysine content in pig blood protein is just high. When it is eaten with staple food, it can play a very good role in supplementing protein-it can not only increase the dietary protein by 20%, but also increase the heme iron by 8.7 mg per 65,438+000 grams 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 functions of moistening intestines, detoxifying, lowering blood pressure and resisting cancer. It can be said that it is 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, pig blood products on the market are mixed and difficult to distinguish. The general purchase principle is: blood products produced by regular manufacturers are purchased from regular sales channels. 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 vendors are expensive in freshness, but there are loopholes in food supervision.

So, 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 excessive consumption should be avoided, otherwise it will easily lead to iron poisoning and bring a burden to human body. Doctors recommend eating pig blood no 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. Growing children and pregnant or lactating women can eat more.

2, anti-aging. Polyphosphate 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 to produce a disinfectant and intestinal moistening substance. This substance can combine with particles and dust that invade the human body, making it difficult to be 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 prevent 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.

Pig blood taboo population

Suitable crowd

1, for healthy and peaceful people, you can eat some pig blood, which has a good nourishing effect on your body.

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

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

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

Taboo crowd

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

2. Not suitable for people with 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 have been added in the production process, so we can only leave it 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've only lived for three months, and I'm less calcium than your son.

Some people think that animal blood can not only supplement iron and blood, but also prevent lung dust and other pollutants.

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 still has some effect on the stomach.

However, counterfeit products made of blood and blood powder account for a large proportion in the market now, so we should pay attention to identification, otherwise it will not only be useless, but also cause 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.) ), in addition to the influence of iron and tannic acid in food, it is also affected by parasites, gastrointestinal function and hemorrhagic diseases.

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

Thank you Yao Ma for your invitation. If the human body is anemic, animal blood-pig blood can be properly supplemented, provided that there is no bacterial pollution and it is not a disease. Tofu cooked in pig blood is delicious, but duck blood is more delicious than pig blood. Jinling duck blood vermicelli soup is better, delicious and famous all over the country. You don't have to be serious about any food, just eat it if you want, don't study, keep healthy, don't overeat, don't eat too much, just let nature take its course, focus on exercise, don't mind, so you can't eat it; Eating like that is not good for your health. Eating more fruits will make you live to be 100 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. It is a popular tonic. However, the most critical problem in eating blood products such as pig blood is food safety, especially for some packaged blood products, it is difficult to judge whether they are hygienic and safe. I suggest you go to a large shopping mall to buy fresh blood. After all, food safety control in big shopping malls can be stricter, and we can eat with confidence. In addition, friends with diarrhea should try not to eat pig blood, because blood has the function of moistening intestines and relaxing bowels to avoid aggravating diarrhea. Finally, I recommend several small recipes for pig blood.

Women are prone to anemia, and 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 other infectious diseases. Therefore, we must pay attention to sterilization and disinfection when eating animal blood products. What we like best in our daily life is pig blood. Every part of the pig can be eaten. Pig blood turns it into a blood clot and can be taken after cooking. The blood-enriching effect of bleeding is particularly good. The price is also affordable. Duck blood is also high in nutrients, but a duck's duck blood is pitiful, so the cost of learning will be much higher. Sheep blood is most suitable for children, pregnant women and nursing mothers, because such people use the most blood, and the nutrition in duck blood just supplements the body. Chicken blood and cow blood are the same. Their blood is flat and suitable for everyone.

I killed pigs when I was a child. There were no slaughterhouses at that time. I'll kill them at home first. At that time, no one went to collect pig blood or anything. Generally, farmers wait for themselves, then cook a large pot full of farmers' iron pots with a diameter of more than one meter, and add some Filipino dishes. Suddenly, most of the village was full of fragrance. Then we packed a bowl of bowls and sent them to every household. This is our habit of killing pigs, and the whole village is the same. When the pig is killed, it will send a bowl to the neighbor. In the past hard years, it was also a rare lost direction, and the spirit of mutual help between township leaders. Although there is nothing now, the past will always be inadvertently remembered and full of beautiful memories.

Modern science has found that pig blood or animal blood products have high nutritional content. Rich in iron, blood protein, a variety of trace elements and so on. Eating pig blood properly can also detoxify the body, remove dust and relieve constipation. 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 the signature dish of many restaurants, attracting diners to move their index fingers and appetite, and contributing to the weight of [spreading hands] [covering face] [covering face].

Pig blood and blood products themselves are generally harmless, and improper and excessive consumption may have certain effects, such as: pig blood is not cooked well enough and turns red after being cooked in time. For example, antler blood drink [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 suck blood as little as possible. There are also some artificial blood products prepared by black-hearted vendors. They are all made of pigments and chemicals, which are harmful to eat. We pay attention to observation and comparison:

1. Hope. It is best to look at the color of blood products, and the color is naturally free of impurities; Dark color, no natural luster, no impurities.

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

3. stop. Blood products should be cut into pieces. Good blood products should be cut into pieces, tender and suitable, with broken hands, and handled with care. Inferior blood products, thick and difficult to cut, are like falling dust when touched, or will not break when rolled up.

Cooking. 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. Inferior blood products have dull color and poor taste, like stirring wax, or have little change after cooking. Cooked for a long time, neither rotten nor old.

At present, we should polish our eyes and distinguish between good and bad food. Health is the capital of revolution. Good health can make you enjoy more delicious food. How to eat blood products?
