Second, the disadvantages of eating pig blood:
It may cause iron poisoning. Generally speaking, the recommended daily intake of iron for normal adults is about 10 mg. Eating too much pig blood will increase the burden on the body. Long-term high-iron diet will lead to iron overload and eventually develop into hemochromatosis, which will damage cells in liver, kidney, mucosa and skin. Therefore, it is generally advisable to eat pig blood twice a week, about 50 grams each time.

Eating this unclean pig blood may have health hazards, so you must go to a regular supermarket or vegetable market to buy it. Some people worry that whether pig blood contains toxins metabolized by animals will be harmful to health. In fact, when blood passes through the liver and kidney, it will be transformed into other substances through metabolic filtration. Unlike toxins, most of these metabolites are harmless and have no harm to human health.
