What are the benefits of eating more pig blood for the elderly?

　　The main purpose of eating meat is to absorb protein, but some elderly people have lost their teeth, have difficulty chewing, have weakened gastrointestinal functions, and have poor digestion of meat foods. At this time, for healthy , the elderly may wish to eat pig blood often.

　　First of all, the high-quality protein content of pig blood is equivalent to that of pork, but it does not have the disadvantages of meat containing a lot of fat. In particular, pig blood has a soft texture, which is easy to chew and digest.

　　Secondly, the number of people over 60 years old in our country anemia The incidence rate is very high, and the result of a recent survey is 21.5%. The iron in pig blood is heme iron, which is not only higher in content than any other food, but also easily absorbed by the human body. Its absorption rate in the small intestine can reach 37%, which is equivalent to the absorption rate of many iron supplements on the market (heme iron), the basic component of which. Therefore, if the elderly eat 20 grams of pig blood every day, they can basically supplement their iron needs and avoid and correct anemia.

　　In addition, pig blood has the function of removing dirt and laxative. The plasma proteins in pig blood are digested and decomposed in the intestines. The remaining undigested residues will absorb a large amount of water and also absorb harmful substances in the intestines, such as metal particles and dust mixed in food, and are excreted with the feces. It not only prevents these substances from causing damage to the human body, but also smoothes the intestines and relieves constipation.

　　Therefore, please invite your elderly friends to eat dishes made with pig blood.

Since heme iron cannot be fully absorbed by the body, the remaining part turns black through the action of gastric acid and digestive enzymes, making the stool tar-like. This is normal and there is no need to worry.
