What are the benefits of eating fish?

1, protect eyesight

Many fish are rich in omega-3 fatty acids. This unsaturated fatty acid is an important part of retina, which plays a key role in promoting the development of retinal tissue and reducing the possibility of yellowing of eyes due to aging.

Step 2 protect the heart

There is less inferior fat in fish, and most of them are unsaturated fatty acids. This kind of high-quality fat can nourish blood vessels and protect the brain. At the same time, it can also achieve the functions of anticoagulation, lowering blood pressure, lowering heart rate, inhibiting myocardial excitability, softening blood vessels, effectively protecting cardiovascular and cerebrovascular health and protecting the heart.

Step 3 supplement nutrition

Fish is rich in protein, and protein also contains vitamin A, vitamin D, vitamin B 1, nicotinic acid and trace elements such as calcium, magnesium, phosphorus, iodine and fluorine, which are essential nutrients for human body. Eating fish regularly can improve human digestion and avoid the problem of insufficient trace elements.

It is suggested to stop eating these six kinds of fish, or contain formaldehyde and heavy metals, and learn as soon as possible.

-Fish with a strong fishy smell

Fish itself has a fishy smell, so you must pay special attention to the price of fish when buying fish food. Some people may choose low-priced fish, but we can find that these cheap fish are too strong to buy this kind of fish.

This fish may live in a polluted water environment for a long time, and the water may contain heavy metals or formaldehyde. Eating this kind of fish is easy to make you sick.

-Giant deep-sea fish

Many people in life may prefer to eat deep-sea fish, thinking that fish living in the deep sea will have higher nutritional value.

The environment of deep-sea fish is more complicated than that of freshwater fish, and there will be more heavy metals in it. It is not recommended for children to eat deep-sea fish, otherwise it will cause serious damage to their health and even the nervous system.

salted fish

Idle fish is a kind of pickled food that many people prefer, especially in Sichuan or Chongqing, especially salted fish.

It is found that salted fish contains dimethylamino salt, which is easy to produce carcinogens and dimethyl nitrite nitrogen after entering human body. Salted fish is a kind of pickled food, and a lot of salt needs to be added in the production process. Eating too much can easily raise blood pressure and even damage renal function, especially for people with urinary inflammation or hypertension, and eat less salted fish.

Freshly slaughtered fish

I believe everyone likes to buy fresh and lively fish when they buy fish, and they think such fish is fresh and tender after slaughter, which is particularly refreshing.

What needs to be reminded here is that freshly slaughtered fish should not be eaten immediately as far as possible, because this kind of fish contains a lot of heavy metals, and it is easy to cause food poisoning when ingested too much, and the heavy metal content in the body is easy to exceed the standard, which affects its metabolic level. Fish should not be eaten for a short time after slaughter, and should be brewed with clear water 1~2 hours before eating.

Fish in sludge

There are many fish living in mud, among which loach and eel are the representatives. Fish living in sludge basically contain heavy metals and formaldehyde, and there are many parasites.

Everyone will choose high-temperature cooking in the production process. Many parasites have the habit of resisting high temperature. Even if most parasites can be eliminated, it is impossible to kill them all. Eating this fish for a long time will do great harm to health.

-Fish has been frozen for too long

In order to extend the shelf life of fish, many people will store fish in the freezer, in order to extend the shelf life of fish and avoid fish spoilage.

If the fish is stored in the frozen area for a long time, not only the nutrients will be lost, but also the eyeballs of the stored fish will be particularly turbid, indicating that this kind of fish has long been stale, and even if it is eaten, it will not bring benefits to the body.

What kind of fish is good for your health?

1, hairtail

If you want to supplement energy and nutrition by eating fish, you can achieve the effects of moistening skin, nourishing hair, nourishing liver and enriching blood by eating hairtail. Eating hairtail can supplement unsaturated fatty acids and lower cholesterol. Hairtail is also rich in magnesium, which can not only effectively maintain cardiovascular and cerebrovascular health, but also effectively prevent diseases such as hypertension.

2. herring

Black herring is rich in selenium, iodine, zinc and nucleic acid, which can prevent cancer and resist aging. Proper consumption of black herring can supplement unsaturated fatty acids, prevent blood coagulation and dilate blood vessels.

3. Carp

Carp is rich in high-quality protein, and its digestibility can reach 96%.
