1. Pay attention to these parts.
(1) Pig neck meat
Pig neck is the place where lymph nodes are concentrated, and lymph nodes are the organs that filter pathogens in animals. Eating lymph nodes by mistake will lead to the decline of human immunity.
When slaughtering, if the germs and viruses in lymph nodes cannot be removed in time, it is difficult to completely remove them when cooking. So, if you can't ensure that the pig's neck is properly handled, don't eat it indiscriminately.
(2) Small kidney
The small kidney, the adrenal gland, is located in the front and upper part of the pig kidney. Eating kidney can cause dizziness, dizziness and other symptoms. In severe cases, blood pressure will rise rapidly and dizziness will occur. However, everyone should pay attention. Small kidney ≠ pig kidney, except small kidney, can be safely eaten.
(3) Pig lung
There are many alveoli in pig lungs, which are places for gas exchange. They will more or less accumulate some dust and breed bacteria, viruses and other substances, which are difficult to clean up. I suggest you eat less.
Pig offal is a frequent visitor at the dinner table, but some parts have been controversial. Let's see what is going on.
Pig liver: more toxins?
The liver is a transit place for toxic substances such as heavy metals, and detoxification cannot be separated from the liver. If it is a healthy pig, the transfer of toxic substances is normal, and the accumulated heavy metals will generally not exceed the standard, so it can be safely eaten.
Eating pork liver in moderation is good for health. Take 1-2 times a month, and control it within 75g each time, which can effectively supplement heme iron and hemoglobin.
Pig blood: iron poisoning?
Pig blood is rich in iron and is an ideal blood-enriching food. Some people say that eating more pig blood will lead to iron poisoning. As long as you don't eat too much pig blood, eating 1-2 times a week will not lead to iron poisoning, but will help your body to supplement iron and clear the intestines and remove dust.
Pig large intestine: unsanitary?
The pig's large intestine is the place where food residues are discharged, and it is also a hotbed of parasites and pathogenic bacteria. Does it mean that the pig's large intestine is unsanitary? In fact, as long as the large intestine is cleaned and fully heated, microorganisms can be killed and it is safe to eat.
2, the efficacy and role of pig blood
1. Prevention of iron deficiency anemia
The content of iron in pig blood is very high, and it exists in the form of heme iron, which is easy to be absorbed and utilized by human body. Children in the growing period and pregnant or lactating women eat more dishes with animal blood, which can prevent iron deficiency anemia and effectively prevent middle-aged and elderly people from suffering from coronary heart disease and arteriosclerosis.
2. Inhibit tumor growth
Cobalt contained in pig blood is an important trace element to prevent the growth of human malignant tumors, which is difficult to obtain in other foods.
stop bleeding
Pig blood contains vitamin K, which can promote blood coagulation, so it has hemostatic effect.
4. Post-illness care
Pig blood can also provide a variety of trace elements for human body, which is beneficial to the recuperation of malnutrition, kidney diseases and cardiovascular diseases, and can be used to treat dizziness, hematemesis, hemorrhage, metrorrhagia, traumatic hemorrhage, convulsion and epilepsy.
5. Human body "sweeper"
Pig blood can also remove the harm of dust and harmful metal particles in human body. Modern medical research has found that protein in pig blood, after being decomposed by gastric acid, can produce a substance that can disinfect and moisten intestines. This substance can react with dust and harmful metal particles entering the human body, and then take these harmful substances out of the body through excretion, which is called "scavenger" of human pollutants.
It should be noted that excessive consumption will cause iron poisoning and affect the absorption of other minerals. Therefore, unless people with special needs, it is recommended to eat no more than twice a week.
