I believe that everyone has heard a saying: eating pig blood can detoxify.
The reason is also very intuitive, eating pig blood, the next day the bowel movement will become black, which is the toxin is excreted.
So, is this statement really true?
The answer is, half right, half wrong.
<h1 class="pgc-h-arrow-right" data-track="7" > First of all, eating pig blood does have a certain detoxification effect. </h1>
Studies have found that after the plasma protein in pig blood is decomposed by gastric acid, it will produce a decomposition of detoxification and intestinal cleansing, which can undergo a chemical reaction with dust and harmful metal particles invading the human body, and is easy to excrete toxins.
Therefore, we will find that in some places, when harvesting rice or wheat, we will deliberately eat some pig blood, just to clean up the dust in the body.
In addition, pig blood itself is also a kind of Traditional Chinese medicine, which has the effect of nourishing blood and nourishing the heart, extinguishing the wind and calming the alarm.
Therefore, eating a little properly is good for the body.
<h1 class="pgc-h-arrow-right" data-track="20" > so why does it turn black after eating pig's blood? </h1>
This is actually not related to detoxification, but because the iron content in pig blood is very high, when passing through the gastrointestinal tract, iron is not fully absorbed, under the action of gastric acid gastric juice, black ferrous sulfide will be produced, making the feces black.
This is a normal phenomenon, and everyone does not have to worry.
Compared with whether pig blood can be detoxified in the end, there is a problem that deserves our more attention -
<h1 class="pgc-h-arrow-right" data-track="23" how to distinguish between real and fake pig blood >? </h1>
Because fresh pig blood contains a lot of oxygen, so the surface of real blood has a lot of stomata, and it is easy to break, and there is a faint fishy smell; false pig red is the opposite, the surface is smooth, cut without stomata, not easy to break, smell no fishy smell.
1. Look at the color: fake pig blood is very bright due to pigment or blood red, while real pig blood is dark red;
2. Touch by hand: fake pig blood is more flexible due to mixed with chemicals such as formaldehyde, how can everything not be broken, while real pig blood is harder, when touched by hand, it is easy to break;
3. Look at the cutting surface: Because fresh pig blood contains a lot of oxygen, so after the real pig blood is cut, the cutting surface is rough, and there are many stomata on the surface; on the contrary, after the pig blood is cut, if the cutting surface is smooth and flat, there is no stomata, indicating that there are false;
4. Smell: Real pig blood, there is a faint fishy smell, if you can't smell a little fishy, it may be fake.
In short, pig blood is indeed a good health food, but we must pay attention to distinguish between true and false.
