What are the questions about animal blood?
0 1. Causes of melena after eating animal blood
Animal blood enters the body, and some red iron cannot be completely absorbed. Unabsorbed heme iron will neutralize the sulfide in the intestine and produce black iron sulfide, which will make the feces black.
02. Can animal blood clear lung?
Nowadays, air pollution is becoming more and more serious, and smog or dust can enter the lungs through the respiratory tract. However, all food is absorbed and broken down in the digestive tract, broken down into small nutritional molecules, and then transported to capillaries to provide cells with the energy they need.
That is to say, eating blood tofu can't clear the lungs.
03. The amount of blood consumed by animals
Although animal blood can bring some benefits to our health, the more the better. If you take too much iron at a time, it will lead to acute iron poisoning.
The daily iron intake of adults is10 ~15mg, which is about 200g pig blood or 50g duck blood. However, special people, such as pregnant women, need more iron, and they need to consume 20~30 grams of iron every day, which is about 100 grams of duck blood or chicken blood.
