I have always heard the old man say that eating pig blood has the effect of clearing the lungs, as for whether there is a clear lung effect, let's have a preliminary understanding.
Let's start with the conclusion: from a scientific point of view, eating pig blood has no effect on clearing the lungs, and rumors have been refuted many years ago.
Pig blood mainly contains hemoglobin, which in turn contains iron, which will produce something called ferrous sulfide under the promotion of human gastric acid.
Ferrous sulfide is mainly presented in the form of black, so the feces that we usually excrete after eating pig blood are black.
This is not what the old people said because of pig serum lung, believe in science, don't be superstitious!
Although pig blood does not have the so-called lung cleansing effect, it is still very delicious as a dish.
I would like to share with you a special dish made of pig's blood:
Friendly reminder: tofu and pig blood should be blanched in advance, if the tofu is blanched, it can effectively remove the beany smell; put a lost salt when blanching pig blood, and the pig blood blanching time should not be too long, about 10 seconds!
If you want the pig blood to be more tender, you can first tofu, and then put the pig blood after the tofu is almost cooked, and the pig blood can be put out of the pot for about 30 seconds!
The pig's blood stewed tofu made in this way is still a special meal.
