Duck blood vermicelli, hair blood wang, pig blood soup... These delicacies are familiar to many people, and pig blood and duck blood are also common hot pot ingredients.
During the May Day period, Mr. Zhang ate pig blood at his parents' house for several days in a row, changing the pattern of eating every day, and his mother told him: Eating pig blood can detoxify, taking advantage of the holiday, I will make you a few more meals.
At the beginning, Mr. Zhang was suspicious of the letter, but he did not expect that the color of the stool became darker after eating, which is to excrete the toxin?
So Mr. Zhang came to Ask Uncle Jiu for verification, in order to solve this problem that bothers many people, today, let's talk about "blood tofu"!
<h1 class="pgc-h-arrow-right" data-track="5" >, eat pig blood, can you detoxify in the end? </h1>
The pig blood we eat is divided into two kinds, one is a more traditional pig blood, the fresh pig blood is put in the container, and then put some table salt, the pig blood is coagulated and cut into a small piece, and it can be eaten after thorough cooking.
Another kind of pig blood is more common in the current market, by adding salt, sodium citrate, thickeners and other food additives to pig blood, under the premise of rational use of food additives, eating such pig blood is safe, there is no health risk.
The nutritional value of pig blood lies in the rich protein and iron, and the fat content in pig blood is much lower than that of meat, and it also contains a certain amount of lecithin, which can prevent arteriosclerosis. Modern medical research has also found that pig blood has a laxative effect.
After eating pig blood, people will turn black, so there is a saying of "pig blood detoxification", that is, the black substance in the stool is the garbage and toxins in the body.
In fact, pig blood contains a large amount of iron, and when iron cannot be fully digested and absorbed, it will form iron sulfide with sulfides in the large intestine. Iron sulfide is black and is excreted from the body with the stool, making the stool also appear black. Therefore, there is no scientific basis for the claim that pig blood is detoxified.

As soon as the news came out, public opinion was in an uproar, and many people could not imagine: duck blood could even be faked! After inspection, it was found that the duck blood sold by the store turned out to be chicken blood, and chicken blood is generally rarely used as an ingredient, because eating chicken blood is easy to increase the risk of disease in some people.
In addition, some citizens reported that the finished pig blood products sold in a market were not selling well, the water content was small, and it looked like chewing gum substances. After the reporter's investigation, it was found that the "fake pig blood" was likely to be mixed with a large amount of water, starch, blood meal, pigments and so on.
In order to make pig blood smooth and tender, merchants will add food additives to pig blood, but as long as the use of food additives meets the regulations, it is generally harmless. The authenticity of pig blood mainly lies in the authenticity of raw materials.
So, how should we choose high-quality duck blood and pig blood? Here Uncle Nine gives everyone a few tricks.
1. Look at the color
Fresh and high-quality duck and pig blood are dark red in color, and should be purchased with caution if the color is close to a coffee or bright red, indicating that it is not fresh or with unknown substances added.
2. Look at the taste
Fresh, high-quality duck and pig blood have a faint smell of blood, and if they smell no, or have a fishy smell, the quality is relatively poor.
3. Look at the degree of softness and hardness
Fresh duck blood and pig blood are relatively elastic and not easy to break, if they are crushed or hard when pressed, it means that they are not fresh enough.
4. Look at the cut surface
Fresh and high-quality duck blood and pig blood, after cutting the cut surface is relatively rough, often with honeycomb holes, if the cut surface is smooth after cutting, there is no stomata, it may be fake duck blood or fake pig blood.
<h1 class="pgc-h-arrow-right" data-track="5" >3. Frequently asked questions about pig blood</h1>
As the saying goes, "complement the shape with shapes", so if you eat animal blood such as duck blood and pig blood, can you replenish blood? In fact, it depends on the situation.
In general, animal blood has only undergone a series of processing, rich in iron content, and the human body is easy to absorb and utilize, which can effectively prevent iron deficiency anemia.
However, consumers should not blindly prevent anemia by eating animal blood, because there are many reasons for anemia, eating animal blood is only effective for iron deficiency anemia, if it is other types of anemia, eating more animal blood is useless.
Moreover, not all people are suitable for eating animal blood. Taking pig blood as an example, people who are not suitable for eating pig blood are:
People with diarrhea and dysentery. People with diarrhea and dysentery have weak gastrointestinal function, pig blood is not easy to digest, and eating will increase the burden on the stomach and intestines.
People with recent gastrointestinal bleeding. After eating pig blood, it is not conducive to judging the amount and nature of gastrointestinal bleeding, which is easy to confuse the disease and affect the treatment.
People who do routine stool testing for the first 3 days should not eat pig blood so as not to affect the test results.
People who are taking warfarin contain vitamin K in favalin and vitamin K in pig blood, and the combination of the two will reduce the efficacy.
Finally, it should be noted that although pig blood and other animal blood are delicious and nutritious, do not eat a lot, according to the "Dietary Guidelines for Chinese Residents", eat 2 to 3 times a month, each time eating about 25g is enough.
