Fish has been regarded as a delicacy since ancient times, and "those who give up fish and take bear's paw are also". In their eyes, fish is even more noble than bear's paw. In the eyes of modern people, fish is more suitable for eating than chickens, ducks and pigs. "Eating four legs is not as good as eating two legs, and eating two legs is not as good as eating without legs." Eating fish often does have many benefits, as long as the ingredients are good and the methods are right, it is simply great.

1, the benefits of eating fish often

1 Patients with cardiovascular diseases often eat crucian carp in winter:

Crucian carp is one of the important edible fish in China. The meat is tender, the taste is sweet and the nutritional value is high. It is rich in protein, fat, inorganic salts, vitamin A, vitamin B and so on. According to the determination, every 100 grams of crucian carp contains about 20 grams of protein, second only to prawns. In addition, the protein contained in crucian carp is easily digested and absorbed by human body, which is a good source of protein for patients with liver, kidney, cardiovascular and cerebrovascular diseases.

Carassius auratus is sweet and warm, enters the spleen and stomach, and enters the large intestine meridian. It is clinically used to strengthen the spleen and promote diuresis, harmonize the middle energizer and stimulate appetite, promote blood circulation and dredge the pulse, and warm the middle energizer and lower the qi. It has direct or auxiliary effects on spleen and stomach weakness, anorexia and fatigue, nephritis and edema, ascites due to liver disease, postpartum hypogalactia's disease, dysentery and hematochezia.

2, women eat more fish, effectively reducing the incidence of stroke:

If women often have fish in their weekly diet, their risk of stroke is relatively low. According to the research results of American scientists, compared with those who eat fish less than once a month, women who eat fish more than five times a week have a 52% decrease in stroke incidence, those who eat fish two or four times a week have a 27% decrease in stroke incidence, those who eat fish 1 time a week have a 22% decrease, and those who eat fish at least three times a month have a 7% decrease.

3. Eat more fish seeds to prevent Alzheimer's disease:

Fish roe is a kind of nutritious food, which contains a lot of nutrients such as protein, calcium, phosphorus, iron and riboflavin. It plays a very good role in human development, strengthening physique and strengthening brain, especially for children and adolescents in physical development.

At the same time, the lecithin contained in fish eggs can increase acetylcholine, so it also has a good effect on dementia due to choline deficiency. However, we should pay attention to the fact that fish eggs contain high cholesterol, so patients with high blood fat and sticky blood are not suitable for eating.

2. Eat less of this kind of fish.

Although the delicious and nutritious value of fish is particularly high, there is a fish doctor who advises not to eat more than one bite. It has been listed as a first-class carcinogen!

In the list of carcinogens published by the World Health Organization, China salted fish has been classified as a first-class carcinogen. Including pickled fish, grilled fish, canned fish, etc., many people like this kind of fish. These fish are not only high in salt, but also rich in oil. In particular, pickled fish has been listed as carcinogenic food by the national cancer research institute, which can increase the risk of various cancers and is one of the foods that endanger human health.

These people eat less fish.

1. Gout patients: Because fish contain purine substances, gout is caused by the disorder of purine metabolism in human body;

2. Patients with hemorrhagic diseases: Patients with hemorrhagic diseases such as thrombocytopenia, hemophilia and vitamin K deficiency should eat less or not eat fish, because the eicosapentaenoic acid contained in fish can inhibit platelet aggregation, thus aggravating the bleeding symptoms of patients with hemorrhagic diseases;

3. Patients with liver cirrhosis: It is difficult for the body to produce coagulation factors during liver cirrhosis, and the platelet is low, which is easy to cause bleeding. If you eat sardines, herring, tuna, etc. rich in eicosapentaenoic acid, your condition will deteriorate sharply, just like adding insult to injury;

4. Tuberculosis patients: When taking isoniazid, some fish are prone to allergic reactions, ranging from nausea, headache, skin flushing, conjunctival congestion, etc., to palpitations, swelling of lips and face, rash, diarrhea, abdominal pain, dyspnea, elevated blood pressure, and even hypertensive crisis and cerebral hemorrhage.

Some people don't like fish very much, not because it tastes bad, but because it tastes prickly and is too troublesome. I suggest that you try to eat more fish and get used to how to spit it. In addition, there are no small thorns in some parts of the fish, such as fish belly and fish head, and some species of fish have few fishbones, such as mandarin fish, snakehead and yellow catfish. Finally, some small fish can be cooked in a proper way without spitting.
