Fish has always been highly regarded as a kind of meat in our daily life. Compared with pork, cattle, sheep and other meats, fish is not only high in protein, easy to absorb and low in fat, so it is the best choice for many people to supplement nutrition. Although fish is delicious, many people have problems in their choice of eating fish. Sometimes, not only will it not be good for our health, but it may even be harmful to our health by ingesting heavy metals. Therefore, we must pay attention when eating fish.

what are the benefits of eating fish for our health?

Supplementing protein

protein in fish is high-quality protein, and compared with protein provided by other meats, protein in fish can be better digested and absorbed by human body, which is a good choice for us to supplement protein.

Protecting the skin

The natural fish oil contained in fish can protect the skin, maintain the collagen activity of the skin, and keep the skin moist, which has a certain beauty beauty effect.

Help to regulate blood lipids

Fish contains unsaturated fatty acids, which can reduce blood viscosity and regulate the blood lipid level of human body, which is helpful to prevent cardiovascular and cerebrovascular diseases.

In daily life, six kinds of fish are actually not recommended, which may be harmful to our health.

freshly killed fish

Nowadays, many people pay attention to killing and eating live fish, which feels the freshest, but this idea is actually incorrect. This is because both wild fish and artificially raised fish contain certain toxins in their bodies, and it is too late to completely eliminate the toxins now, which may have adverse effects on our health. And the protein in the fish just killed is not completely decomposed, so the taste is not necessarily more delicious. The correct way is to soak the killed fish in clear water for an hour before cooking, which is more appropriate.

Too big fish

In the ecological environment, the harmful substances are increasing step by step. The larger the fish, the more toxic substances are enriched, and the heavy metals are often more likely to exceed the standard, which is harmful to the health. Therefore, don't buy too big fish in your daily life, it is easy to produce more harmful substances.

Fish with high mercury content

Most fish contain slight mercury pollution. Adults can metabolize harmful substances by themselves, but pregnant women and children can't eat these fish, which may lead to mercury poisoning and directly threaten their health. Therefore, we should try our best to avoid eating this kind of fish in our life. There are many large marine fish, such as tilapia, shark, marlin and so on. The mercury content in these fish is likely to exceed the standard, so we should try our best to reduce consumption.

Raw fish

Like our neighbors, we especially like to eat sashimi, but in fact sashimi is a great threat to our health. This is because fish is eaten raw without cooking, which may contain a lot of bacteria and parasites, which may cause serious gastrointestinal discomfort if eaten directly. Therefore, it is recommended not to eat sashimi, but to choose cooked fish as far as possible.

fish gall

Because fish gall has the function of clearing away heat and reducing fire in traditional Chinese medicine, it is actually a serious mistake for someone to eat fish gall raw, because fish gall contains substances that are harmful to human body, such as amino acid and fish gall toxin, which may lead to serious renal failure and even directly threaten life. Fish gall in traditional Chinese medicine is roasted by professional baking, not raw fish gall. We should pay attention to the distinction and don't listen to folk tales.

salted fish

many people like to eat salted fish, which is unique in taste and easy to preserve, but it is actually not a good habit. This is because the salt content of pickled fish generally exceeds the standard, and it is easy to cause cardiovascular and cerebrovascular diseases such as hypertension if eaten frequently. Besides, pickled food also contains nitrite and nitrosamine, which is carcinogenic, and long-term consumption will pose a threat to our health, so we should try to choose fresh fish to eat.

Fish meat is delicious, and it is loved by people of all ages in Xian Yi. However, not all people can eat fish. Some people should pay great attention to eating fish, otherwise it may cause serious harm to their health.

Patients with kidney disease should pay attention to eating fish

Patients with kidney disease generally have to control their diet and dare not eat anything, but doctors generally suggest that patients with kidney disease can supplement high-quality protein in moderation, which can enhance their physique, and fish is a kind of high-quality protein that is easy to digest and absorb. However, fish contains phosphorus and is not friendly to patients with kidney disease. Therefore, patients with kidney disease need to strictly control the consumption of fish meat, and try to choose fish meat with less phosphorus, such as herring, crucian carp and so on. Moreover, patients with kidney disease should eat less than 5g of fish every day, which is not easy to increase the burden on the kidneys and can help supplement protein.

People with gout need to pay attention to

Because fish contains purine, and foods with high purine content can lead to gout, people with gout should also pay attention to the eating taboos of fish. Gout patients should not eat fish, but should choose the most suitable fish, mainly fish with low purine content. It is generally recommended to choose carp, eel, cod and so on. For example, fish with high purine such as sardines should try not to eat, for the sake of their health.

Fish has a wide audience, and its own fat content is low, which is better for people with cardiovascular and cerebrovascular diseases. Moreover, fish helps digestion, and it is also a good choice for human body to supplement protein. However, we should also pay attention to the correct choice of fish. Fish with low purine and low mercury content is our best choice, and try not to eat raw fish, or it is best to eat it cooked.
