The advantages and disadvantages of eating fish, fish has rich nutritional value, and eating fish has a very significant health care effect. Even people who want to keep fit can enjoy the delicious fish. Let's share the advantages and disadvantages of eating fish.

The advantages and disadvantages of eating fish 1 Eating fish to prevent stroke: Eating more fish has a protective effect on cardiovascular and cerebrovascular diseases. Studies have shown that the higher the content of protein and sulfur-containing amino acids in the diet, the lower the incidence of hypertension.

Fish protein is rich in egg amino acids and taurine, both of which are sulfur-containing amino acids. It can affect the regulation mechanism of blood pressure, increase the urine sodium output, thus inhibiting the influence of sodium salt on blood pressure and reducing the incidence of hypertension. Experts suggest that one of the effective ways for middle-aged and elderly people to prevent cardiovascular and cerebrovascular diseases is to take three or four grams of fish oil every day.

Eat fish to prevent aging: In German history, there was a famous prime minister named Bismarck. He ate too much and smoked too much for years. At the age of 68, his body was weak, his face was wrinkled and his eyes were dull, as if death were waving to him.

But then he listened to the doctor and ate herring every day. Soon, a miracle appeared: his skin was ruddy, his eyes were bright and he was full of energy, and he lived until he was 83 years old.

Eating fish is good for your health, but there are the following exceptions:

1, eating contaminated fish will cause skin allergies or allergies to other organs,

2. Pregnant women should eat as little fish as possible. According to Reuters, researchers in Hongkong, China found that pregnant women who eat a lot of fish for a long time will pass the mercury they ingest to the fetus through the placenta, which may affect the intellectual development of the baby after birth.

Although there are many benefits of eating fish now, many water quality is not very good because of the environmental impact. If we eat some fish poisoned by sewage, our health will be destroyed. Usually, if the cooking is not ripe, there will be many parasites in the fish, so parasites will form in our intestines, which is also harmful to health.

Advantages and Disadvantages of Eating Fish 2 Fish can be seen everywhere with the traditional Chinese culture of our Chinese culture. In ancient legends, our ancestors regarded fish as a symbol of strong reproductive ability, and there must be a plate of fish during the New Year or festivals. There are also many fish in folk New Year pictures, and fish are used in ancestor worship.

This shows how much fish affect our daily life. In modern life, everyone often has fish on the dinner table, and fish has penetrated into our lives. So what are the benefits of eating fish?

Benefits of eating fish There are many kinds of fish. Generally, fish are divided into two types-marine fish and fish. Whether it's marine fish or fish, it's just that the marine world of food, clothing, housing and transportation is different, and they contain similar nutrients. The only difference is how big the nutrients are and how big the taste is.

Compared with other meat products, poultry meat, such as goose and pig, is more fleshy, fresh, delicious and nutritious, and is a high-quality source of some vitamins and minerals. Compared with other poultry meat foods, eating fish can provide nutrients needed by the human body, and it can also provide less unhealthy ingredients.

Although there are many benefits, there are still many disadvantages of eating fish. It is best for people with the following symptoms to eat less or not:

First, gout patients.

Some freshwater fish have high purine content, and gout is caused by purine metabolism disorder in the body.

Second, patients with exudation tendency, such as thrombocytopenia, hemophilia, lack of vitamin B 12, etc.

Because fish often contains eicosapentaenoic acid, it can inhibit platelet aggregation, thus aggravating the condition of patients with diseases.

Third, patients with liver cirrhosis.

Thrombin can't be produced in patients with liver disease, and platelets are low, which is easy to cause bleeding. If we take tuna, herring and bluefin tuna containing 20 C 5 enoic acid again, the condition will be greatly deteriorated.

Fourth, tuberculosis patients.

When taking this medicine, if you eat some freshwater fish, it is easy to have allergic symptoms. Mild nausea and vomiting, headache, redness of the skin, conjunctival congestion, severe palpitations, swelling of the lips and face, rash, diarrhea, abdominal pain, poor breathing, and even lead to hypertension and cerebral hemorrhage.

"If you are about to face an important task or exam, I suggest you eat more fish." A study published in the journal Science Library of the United States pointed out that fish oil rich in omega-3 fatty acids was provided as a dietary supplement to a group of young people aged 18~25.

After six months, their brain power has been steadily improved. The reason is that researchers believe that omega-3 fatty acids can affect the storage function of memory.
