What are the health benefits of eating fish?

1. Eating fish is helpful for human development.

Fish is rich in protein, and the protein content per 500 grams of fish is equivalent to the protein content of 600 grams of eggs or 850 grams of pork.

Abundant protein is the carrier of human life. It has the functions of nutritional balance, regulating water balance in the body, improving immunity, and can effectively help the growth and development of children, children and adolescents. It's one of the reasons we eat fish when we're sick or injured, because fish can also help wounds heal and heal.

2. Eating fish can help lower cholesterol.

Most of the fats in fish are unsaturated fatty acids, which are easily digested and absorbed by the human body. The digested and absorbed fatty acids can combine with blood cholesterol in the blood to take cholesterol away from the blood vessels, thereby reducing the content of cholesterol in the body, which is beneficial to health.

3. Stroke prevention.

Fish protein is rich in sulfur amino acids, which can affect the blood pressure regulation mechanism and increase urinary sodium excretion, thereby reducing the effect of sodium salt on blood pressure and reducing the incidence of hypertension.

In addition, fish is rich in unsaturated fatty acids, which can reduce triglyceride and LDL cholesterol levels, and reduce platelet aggregation, thereby preventing cardiovascular diseases such as hyperlipidemia and stroke.

4. Eating fish makes people smarter.

Eating fish regularly is also very helpful for our brains because fish is rich in DHA, which is mainly found in the brain, retina and nerves. DHA can not only maintain the normal function of the human retina, but also contribute to the development of the human intellectual system. Therefore, eating more fish will make people smarter.

5. Eating fish is easy to digest.

Many foods are not easily digested, and fish is an easily digested food. Fish are easily digested and absorbed by the body. The protein structure in fish is soft, the muscle fiber structure is relatively short, the water content is high, and the absorption and utilization rate is as high as 96%.

6. Improve the body's immunity.

Eating fish regularly can improve the body's immunity and increase muscle content, because fish is rich in protein, and the protein is relatively delicate and easy to absorb.

Properly eating fish can improve the immune substance content of the body by supplementing protein, and can also provide rich raw materials for muscles, thereby making the body stronger.

Reminder: Eat as little as possible of the five kinds of fish. Many people may not know it yet, so you might as well learn about it.

1. Salted fish

Studies have found that salted fish contains a large amount of carcinogens, and a large amount of consumption is prone to serious diseases such as nasopharyngeal cancer and gastric cancer. In addition, the salt content in salted fish is particularly high, and excessive intake may lead to cardiovascular and cerebrovascular diseases.

Salted fish will have a lot of salt added during the curing process, which will reduce its protein content. Regular consumption of salted fish can cause excessive sodium content in the human body, which has a great impact on health.

2. Sashimi

With the continuous improvement of living standards, people's pursuit of delicious food is getting higher and higher, but some foods are not good for human health, such as sashimi. There may be some parasites in sashimi. The large number of bacteria and parasites in the human body can have a great impact on the gastrointestinal tract.

In addition, excessive storage of parasites in the human body can lead to parasitic diseases, thereby increasing the incidence of liver cancer. Doctors advise not to eat too much sashimi on a daily basis. Because sashimi food is not sterilized, the microorganisms and bacteria inside can damage the health of the gastrointestinal tract. If you eat sashimi regularly, you will experience adverse symptoms such as abdominal pain and diarrhea.

3. Seriously polluted fish.

Highly polluted fish not only carry bacteria, but also contain high levels of heavy metals. It is recommended not to eat this fish. While this fish is relatively cheap and affordable, there are not many. Money is far less important than health.

Many chemical plants discharge raw sewage into rivers and lakes, where fish grow in seawater. Growing in this environment for a long time can cause fish to contain more harmful substances and heavy metals. Although it will not kill the fish, eating this fish can cause the body to disintegrate.

4. The fish is too big.

Generally, we eat freshwater fish, which are farmed in ponds. In pursuit of profit, businesses may feed some hormonal feeds that make the fish too large.

In addition, a fish that is too large also means that it has survived for a long time and may have higher levels of hormones in the body. The flavor of this fish is usually not tender and more like firewood. It is recommended to avoid eating such large fish as much as possible.

5. Fish with red flesh.

Under normal circumstances, fish should be white, but if we find that fish is red, it is because fish protein contains an amino acid called histidine. If the fish is not stored properly after death, the bacteria multiply to break down the protein and convert histidine to histamine.

Histamine Zuan is a poisonous substance. Half an hour after entering the body, we have shortness of breath, rapid heartbeat, and may also experience symptoms such as vomiting and numbness in the limbs.

What should I pay attention to when eating fish?

1. Do not eat undercooked fish.

Eating undercooked fish can lead to parasitic infections. When you cook fish at home, make sure the fish flakes easily and is smooth, and the flesh shouldn't show any signs of translucency. Do not place uncooked fish with other foods to avoid cross-contamination.

2. Do not eat fish on an empty stomach.

In order to lose weight, many people who love beauty eat fish on an empty stomach without eating anything else. This is a very dangerous behavior.

Because fish is high in purines, it's especially prone to gout if you eat it on an empty stomach. So when you eat fish, you have to eat some other staple food or vegetables, not on an empty stomach.

3. Gout patients should not eat fish.

Fish, shrimp, shellfish, and other foods are rich in purines, and gout is caused by abnormal purine metabolism in the body. Therefore, people with gout should avoid all meat and foods high in purines during an acute attack. During remission, they should eat fish and meat in rations. Do not take too much at one time
