Pig blood does have the function of enriching blood.
Animal blood is rich in protein and iron, which is suitable for developing children, pregnant women, lactating women and anemic teenagers, and can prevent and correct iron deficiency anemia. Protein in animal blood belongs to high-quality protein. Hemoglobin can supplement the iron needed for hematopoiesis, which is easier to absorb than iron ions in ordinary food. Therefore, animal blood can not only enrich blood, but also be regarded as a good food for enriching blood.
Nutritional value of pig blood
Pig blood is not only rich in easily absorbed iron, but also rich in vitamin K, vitamin B2, calcium, phosphorus, iron and various amino acids needed by human body. Its nutrition is similar to that of pork, but according to relevant data, the content of protein is twice as high as that of pork, which is a highly nutritious food. Blood tofu made of pig blood is also called "liquid meat".
Chinese medicine believes that pig blood is light and salty, and it is recorded in the Collection of Medical Forests that eating pig blood can "benefit the large intestine".
Pig blood is not suitable for everyone.
The cholesterol content in animal blood is relatively high, which is not suitable for people with hyperlipidemia, obesity and fatty liver. In addition, blood is the carrier of transporting nutrients and metabolic wastes in animals, and it contains wastes produced by metabolism in animals, including hormones, urea, drugs, veterinary antibiotics and so on. Eating in large quantities will bring a burden to the human body. Therefore, it is recommended not to eat it every day, just 2-3 times a week.
Pig blood is not suitable for eating during gastrointestinal diseases, because pig blood will change the color of feces, and it can't find blood in stool in time. Therefore, eating should be avoided before intestinal examination and during gastrointestinal diseases.
note:
Although pig blood and duck blood have the function of enriching blood, when the cause of anemia is serious and uncertain, it is best to seek medical attention in time to find out the cause, which can not be made up by eating a few good meals. Excessive anemia may require blood transfusion treatment.
