1. There is no essential difference between pig blood and duck blood, except for trace elements. The essence of pig blood and duck blood is protein, and there is no great difference. However, in the presence of trace elements, the iron content of duck blood is still relatively high. For those who need iron supplementation, duck blood is indeed a very good choice. People's impression that duck blood is healthier than pig blood is also due to the existence of iron, which is still important to the human body, but it needs to be taken in moderation.
Second, pig blood and duck blood are actually replaceable, but there is a difference in taste between them. Pig blood and duck blood are usually ordered when eating hot pot, and some people choose them when cooking, but they are relatively few. This is because duck blood and pig blood are still very particular about freshness, and duck blood and pig blood that have been separated for too long are inedible. When eating hot pot, people will choose duck blood and pig blood differently, because there are differences in taste between them, and duck blood will taste better.
Third, compared with duck blood, there will be more people who like and choose duck blood.
