These nutritional characteristics of pig blood are especially suitable for the elderly. The health of the elderly turns from prosperity to decline, and the anabolism of protein gradually slows down, such as the decrease of hemoglobin synthesis, so it is prone to senile anemia. It is generally believed that the high-quality protein in the diet of the elderly should account for about 50% of the total in protein, and protein 1 ~ 1.2g is needed per kilogram of body weight every day. Pig blood contains 8 kinds of amino acids needed by human body and is an ideal food for the elderly. Pig blood is rich in iron, which is an indispensable component of hematopoietic system, and can play a role in "enriching blood" for iron deficiency anemia that is easy to occur in the elderly. Trace elements such as zinc and copper contained in pig blood have the functions of improving immune function and anti-aging. Old people often eat pig blood, which can delay the aging of the body and keep their ears and eyes bright. Pig blood also contains a certain amount of phosphatidylcholine (lecithin), which can inhibit low density lipoprotein and help prevent arteriosclerosis, and is beneficial to patients with hypertension, coronary heart disease, hyperlipidemia and cerebrovascular diseases. In addition, the elderly are prone to malnutrition because of tooth loss, chewing difficulty and decreased digestive function. Pig blood is as soft as tofu, easy to chew and digest and absorb. Therefore, the elderly often eat pig blood, which is not only nutritious, but also beneficial to health.

Modern medical research has found that pig blood can absorb "garbage" in the body. After the plasma protein of pig blood is decomposed by human gastric acid and digestive enzymes, it will produce a substance that can detoxify and moisten intestines. This substance can react biochemically with dust and harmful metal particles that invade the human body, become waste that is not easily absorbed by the human body, and then be excreted from the digestive tract. Now environmental pollution has become a global public hazard. Not only teachers, miners and cleaners are seriously polluted by dust, but almost all urban residents are also harmed by dust. Therefore, eating pig blood often can not only increase nutrition, but also excrete harmful waste in the body, so it is an ideal health food. Medical practice has proved that the trace element cobalt in pig blood can prevent the growth of developing tumors.
This hormone in pig blood not only has therapeutic effect on cancer, but also plays an important role in treating heart disease. In addition, the iron rich in pig blood is almost all bivalent iron (heme iron) easily absorbed by human body, which has a good blood-enriching effect. Nutrition experts have confirmed in experiments that the absorption rate of heme iron in the small intestine can reach 23-37%, while the absorption rate of non-heme iron (iron contained in vegetable, fruit, beans and other plant foods) is only about 9%, so China has always said that "blood is used for enriching blood".
1. Nutrient-rich pig blood is rich in protein, 8 amino acids and various trace elements necessary for human body, with less fat content. Therefore, eating pig blood regularly can not only absorb the nutrients needed by the human body, but also do not have to worry about getting fat.
2. The folk saying of "enriching blood" that can prevent anemia is correct from the perspective of iron nutrition. The intake of a large amount of heme iron is bound to play the role of promoting blood production and enriching blood, and the iron rich in pig blood is almost all heme iron easily absorbed by human body. Therefore, pig blood has a good blood-enriching effect.
It is the "cleaner" of human body. After the plasma protein of pig blood is decomposed by gastric acid and digestive enzymes, it will produce a substance that can detoxify and moisten intestines. This new substance can react biochemically with dust and harmful metal particles that invade the human body, become waste that is not easily absorbed by the human body, and then be excreted. Therefore, eating pig blood often can excrete harmful substances from the body.
4. Anti-aging pig blood contains more chromium, which has a good preventive and therapeutic effect on arteriosclerosis and coronary heart disease. In addition, there are many phospholipids in pig blood, which can increase the amount of acetylcholine and make the connection between nerve cells rapid, thus improving people's memory. Therefore, patients with early Alzheimer's disease should eat more pig blood.
5. Medical practice with anti-cancer effect has proved that trace element cobalt in pig blood can prevent the growth of malignant tumor. Scientists isolated a 1 substance named "trauma hormone" from pig blood, which can remove necrotic and damaged cells and act on injured tissues to gradually heal them and restore their normal functions.
