Four rules for eating fish: Four types of people should not eat fish

Fish is a rare healthy food. It tastes delicious and is rich in nutrients. It is the first choice for a healthy diet. It should be pointed out that there are many types of fish, but not every type of fish has the right nutritional value for everyone. Below, the editor introduces the nutritional value of 6 kinds of fish commonly eaten by Chinese people, analyzes groups of people who should not eat fish often, and protects your healthy diet.

Fish is rich in thiamine, riboflavin, niacin, vitamin D and a certain amount of minerals such as calcium, phosphorus, and iron. Although fish meat has a low fat content, the fatty acids in it have been shown to have blood sugar-lowering, heart-protecting and cancer-preventing effects. Vitamin D, calcium and phosphorus in fish can effectively prevent osteoporosis. Traditional Chinese medicine believes that eating fish should be done according to the symptoms. Only by eating fish according to the symptoms can its edible and medicinal value be revealed.

Four rules for eating fish

The first rule: Eat sea fish and river fish alternately to achieve a balanced nutrition.

According to surveys, both river fish and sea fish have high nutritional value. However, eating only one type of fish for a long time will lead to nutritional deficiencies. Therefore, if conditions permit, it is best to eat river fish and sea fish alternately.

Commonly eaten river fish include crucian carp, grass carp, eel, etc. If cooking for children, eel is the best, because it contains more iron than other fish, and has no fish bones, so it is delicious and easy to cook. ;If you want to eat marine fish, deep-sea fish is the best, such as salmon, trout, etc. Deep-sea fish are rich in unsaturated fatty acids, especially omega-3 fatty acids, which are very effective in maintaining cardiovascular health and reducing inflammatory responses. This fatty acid is very rare in poultry and livestock.

There is also a little common sense. We often think that frozen sea fish is not fresh and should not be given to children to eat too much. There is a misunderstanding here, because deep-sea fishing requires freezing of fish, but quickly frozen fish can actually preserve the nutrients in the fish meat very well. Therefore, frozen sea fish is also a good choice.

The second rule: Do not eat fish alone, otherwise your health will be unbalanced.

The more fish you eat, the better. Because fish is not a perfect food. For example, the content of the mineral iron in most fish is not as high as that in beef and mutton. Therefore, you should eat several kinds of meat together, with slightly more fish being better. It is recommended to eat fish at least twice a week, 100 to 150 grams each time, and at least one of them should be high-fat fish. For children, the number can be halved accordingly.

Rule 3: Steaming fish is the healthiest way to cook it.

Mothers often use how much their children eat as a criterion for measuring their children's appetite, so when cooking fish, they usually use frying or deep-frying to make fish cakes, fish balls and the like. Children like this type of fish. However, in order for children to absorb more nutrients, it is better to steam the fish, because the cooking temperature is lower, which can ensure that the protein and fat in the fish are not destroyed. Stewed soup is also very good, especially "fish head stewed with tofu". After a long time of stewing, the rich collagen in the fish head can be fully dissolved, and the calcium is easier to be absorbed by the human body.

Avoiding frying or deep-frying can also help prevent children from becoming too obese.

Rule 4: Children can eat more fish brains and fish eyes.

Fish brain is rich in DHA, commonly known as "brain gold", and phospholipids, which help brain development. There is also a saying that "eating eyes can nourish the eyes", which makes sense. DHA can also promote the development of children's retina. Therefore, it is recommended that you do not burn the fish eyes when cooking fish, and keep them intact, especially the eyes of deep-sea fish, which are more beneficial for eye repair.

It should be noted that people with the following diseases should not eat too much fish. These diseases are:

1. Gout patients, because fish contains purine substances, and gout is caused by the disorder of purine metabolism in the human body;

2. Patients with bleeding diseases, such as thrombocytopenia, hemophilia, vitamin K deficiency and other bleeding diseases should eat less or no fish, because the 20-carbon 5-enoic acid contained in fish can inhibit platelet aggregation, thereby aggravating the bleeding symptoms of patients with bleeding diseases;

3. Patients with liver cirrhosis have difficulty in producing coagulation factors, and their platelets are low, which can easily cause bleeding. If they eat sardines, herring, tuna, etc., which are rich in 20-carbon 5-enoic acid, their condition will deteriorate sharply, just like adding insult to injury.

4. Tuberculosis patients are prone to allergic reactions if they eat certain fish while taking isoniazid. 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.
