The reasons why you should not eat more pork liver:
1. Heavy metal residues
Pork liver is the largest detoxification device and poison transfer station in the pig body. Toxic and harmful substances such as heavy metals, veterinary drugs, and pesticides enter the human body through metabolism, transformation, detoxification, etc., and are excreted through the liver. These substances accumulate in the liver when liver function decreases or when toxic substances are consumed. Eating too much of this kind of pig liver is harmful to human health.
2. Vitamin A poisoning
Pork liver has a particularly high vitamin A content, so the more you eat, the better. Vitamin A is fat-soluble and is not easily excreted from the body. Excessive intake may cause toxicity and abnormal bone growth, which may have a greater impact on pregnant women and may affect fetal development.
3. High cholesterol
The cholesterol content of every 100 grams of pork liver is 288 mg, and the recommended daily cholesterol intake is 300 mg. Although the new dietary guidelines no longer limit cholesterol intake, the total dietary fat intake still needs to be controlled, otherwise it will affect human cardiovascular health and be detrimental to the control of the course of diseases such as hypertension.
Extended information:
Each 100 grams of pig liver contains about 8,700 international units of vitamin A, and the daily requirement for adults is 2,200 international units. If you eat a large amount of pig liver, your body will suffer from vitamin A deficiency. Too much A content results in the inability to be excreted by the kidneys, leading to poisoning. Poisoning can cause nausea, vomiting, headache, drowsiness, blurred vision, etc. Over time, it can lead to osteoporosis, rash, dry hair and other symptoms, and it also has a certain damaging effect on the liver.
Each 100 grams of pork liver contains more than 400 mg of cholesterol, and a person should not consume more than 300 mg of cholesterol from food every day. Exceeding the normal amount of cholesterol can lead to arteriosclerosis and aggravate cardiovascular disease. Diseases, especially those with hypertension and coronary heart disease, should pay more attention. Therefore, it is better to eat pork liver in moderation and not to eat too much.
