Is eating fish every day harmful to your health?

Fish is a very common thing in our lives, and everyone knows that eating fish regularly is good for the body. The protein and vitamin content in fish is very high. Eating fish can also prevent cardiovascular disease, reduce the cholesterol content in the human body, and promote the development of the human brain. Eating fish every day is not harmful to the body, but not all fish can be eaten.

Three types of fish that are not suitable to be eaten frequently!

1. Marinated fish

Speaking of salted fish, I believe many people like to eat it. However, salted fish cannot be eaten for a long time. In addition, children and pregnant women cannot eat salted fish, because salted fish is likely to affect the child's brain development or cause symptoms of dystocia in pregnant women. If normal people often eat salted fish, it is very likely to cause high blood pressure, heart disease, and even cancer. Therefore, even if you like salted fish, don't eat it often.

2. Sashimi

Many people have heard of the name of sashimi. In some people's imagination, sashimi is a high-end food. In fact, sashimi is not that high-end, most of it is just hype by merchants. First of all, a lot of sashimi contains parasites. If people eat these parasites, they will be very difficult to eliminate and will cause great harm to the human body.

In addition, some unscrupulous businessmen in our country sell parasites that look like salmon as salmon. When this parasite is cut into slices, it is very difficult to tell whether it is salmon or not, so try not to buy sashimi in your daily life.

3. Catfish

Many people like to eat iron pot catfish, but I don’t know if you are aware of the fact that iron pot catfish is caused by Gouchen disease. The so-called Gou Chen disease is not a disease, but refers to the recurrence of a disease that existed in the body before and was completely cured. Even if a person does not have any disease before, eating catfish for a long time will increase the risk of disease.

This is because the habitat of catfish is very complex. According to research, catfish surviving in sewers are more than 20 times larger than catfish growing in ordinary clean water.

People who are not allowed to eat fish

1. People who take certain medications

People who take cough medicine should not eat fish, especially deep-sea fish, so as not to cause an allergic reaction to histamine, which may lead to uncomfortable symptoms such as skin flushing, conjunctival congestion, dizziness, rapid heartbeat, urticaria, etc. Many deep-sea fish contain histamine. Once the histamine level in the human body exceeds the standard, the substance will enter the human blood circulation and cause a histamine allergic reaction. The reason why you don't experience the above-mentioned discomfort symptoms when eating deep-sea fish is because there is a substance in the human stomach and liver that inhibits the activity of histamine - monoamine oxidase, which prevents histamine from entering the blood. However, some cough medicines contain monoamine oxidase inhibitors, which will inhibit the secretion of monoamine oxidase in the human stomach and liver. Eating deep-sea fish at this time can easily cause histamine to accumulate rapidly in the body.

In addition to cough suppressants, there are other drugs that can inhibit monoamine oxidase. Antibacterial drugs, such as furazolidone (such as furazolidone, etc.), ketoconazole, griseofulvin; antihypertensive drugs such as pargyline; selegiline for the treatment of Parkinson's disease; antidepressants such as moclobemide; anti-tumor drugs such as procarbazine, etc. There are also drugs in traditional Chinese medicine that can inhibit the action of monoamine oxidase, such as deer antler, hawthorn, Polygonum multiflorum, etc.

2. Patients with liver cirrhosis

When the liver is cirrhotic, it is difficult for the body to produce coagulation factors, and the platelet count is low, which can easily cause bleeding. If you eat sardines, herring, tuna and other fish rich in 20-carbon 5-enoic acid, the condition will deteriorate sharply, just like adding insult to injury.

3. Pregnant women

Pregnant women should not eat marine fish frequently. Frequent consumption of seafood will lead to excessive intake of methylmercury. The higher the amount of mercury the fetus is exposed to in the womb, the greater the risk of slight delays in the development of other functions of the child, such as attention, memory, and language skills. Scientists also warn that even if the mother does not consume much mercury, the brain development of her fetus may be delayed. For this reason, pregnant and breastfeeding women should eat less seafood, no more than 1 to 2 times a week, less than 100 grams each time, and avoid eating tuna, swordfish and other marine fish with high mercury content. They can choose to eat pond-raised fish that are not contaminated by mercury.

4. Patients with bleeding disorders

Patients with bleeding diseases such as thrombocytopenia, hemophilia, and vitamin K deficiency should eat less or no fish, because the eicosapentaenoic acid (EPA) contained in fish can inhibit platelet aggregation, thereby aggravating the bleeding symptoms of patients with bleeding diseases.

5. Tuberculosis patients

If you eat certain fish while taking isoniazid, you are likely to have an allergic reaction. Mild symptoms include nausea, headache, skin flushing, conjunctival congestion, etc. Severe cases include palpitations, numbness and swelling of the lips and face, rash, diarrhea, abdominal pain, difficulty breathing, high blood pressure, and even hypertensive crisis and cerebral hemorrhage.

6. Gout patients

Because fish contain purine substances, and gout is caused by a disorder in purine metabolism in the human body.
