Why can't you eat too much pork liver?

Animal liver is an important detoxification and metabolic organ in animals. Pork liver can be described as the largest "detoxifier" and "transfer station" of poisons in the pig body. Toxic and harmful substances that enter the body, such as heavy metals, veterinary drugs, pesticides, etc., are metabolized, transformed, detoxified and excreted in the liver. When liver function declines or toxic and harmful substances are ingested in large quantities, the liver will accumulate these harmful substances.

The investigation found that the content of heavy metal cadmium and lead in pig liver was high, at 0.149 mg/kg and 0.703 mg/kg respectively, both exceeding my country's food hygiene standards and it is not advisable to eat too much.

In addition to heavy metals, pig livers also tend to have higher levels of veterinary drug residues. A survey in Chengdu found that among commercially available animal products, pig livers have higher levels of veterinary drug residues. Although most of them do not exceed the standard, they are still relatively high compared to pork, beef, etc. In general, the toxins in animal organs such as pig livers and pig hearts are often high.

In addition, the cholesterol content of pig liver is also high, with 100 grams of pig liver containing 288 mg of cholesterol. Excessive intake of cholesterol, especially high intake of low-density cholesterol, will increase the risk of cardiovascular disease. For health reasons, the cholesterol content ingested from food should not exceed 300 mg per day. In short, eating a large amount of pig liver for the so-called "eye-improving" effect is not the best choice.

Nutritional value of pork liver

Pork liver contains more protein than pork heart and ranks first in fat content. The starch content of liver is not only higher than that of lean meat, but also easily hydrolyzed into glucose. The iron content is 18 times that of pork. It also contains rich minerals, trace elements, vitamin A, thiamine, riboflavin, niacin, ascorbic acid and other ingredients. Therefore, it has a strong blood-tonifying effect and has a nourishing effect on people with blood deficiency, physical weakness and poor vision.

Precautions for eating pig liver

1. People with high blood pressure should eat less pork liver

Pork liver contains a high proportion of cholesterol. Eating too much at once will absorb a large amount of cholesterol, leading to arteriosclerosis and cardiovascular disease. Therefore, patients with hypertension should eat less pork liver.

2. Soak the liver before eating

Pork liver should be soaked in salt water for about 10 minutes before processing, or better yet, for more than 30 minutes. Thus, the toxins in the liver are broken down. Since the toxins in the pig liver may not be completely cleared, these toxins will remain in the blood of the liver, which may lead to cancer, leukemia or other diseases.

3. Do not eat pork liver with foods rich in vitamin C

Pork liver is high in copper, which can combine with vitamin C to cause the food to lose nutrition. For example, do not stir-fry bean sprouts with liver. Since part of the bean sprouts contains high vitamin C, mixing the two types together will oxidize the vitamin C in the bean sprouts and reduce the nutrients in the bean sprouts to zero.

4. Must be cooked

If the processing time is too short, some pathogens and parasite eggs in the liver will not be killed. Therefore, if you eat pork liver, you should not only simply process it, but also thoroughly kill the bacteria and parasite eggs in the liver.

5. Pregnant women should not eat pork liver frequently

In addition, if pregnant women eat too much pork liver, it will lead to excessive vitamin A in the body, which is not good for both pregnant women and fetuses. Pregnant women with excessive vitamin A in their bodies will experience symptoms such as dizziness, nausea, skin damage, and the fetus may also cause deformities. Therefore, pregnant women should try to eat less pork liver.
