Where not to eat the head of the fish Which parts of the fish should not be eaten

Fish gall bladder. Rumors have been circulating about eating fish gallbladder to cure diseases, but the truth is that a lot of fish gallbladder is poisonous. Eating fish gallbladder will be poisoned, almost no suspense.

Freshwater fish such as herring, grass carp, silver carp, sea bass, and carp contain highly toxic bile toxins in their gall bladders, which are not easily destroyed by heat and ethanol (alcohol). Note that when cleaning the internal organs of the fish, be sure to remove the fish gallbladder.

Fish head. Fish head meat is a favorite of many people, and just looking at a plate of chopped pepper fish head makes my mouth water. However, it is best to eat less fish heads, which are generally more likely to accumulate heavy metals, and children should not eat them for a long time.

With the increase of fish age, the mercury content of fish meat and roe did not change significantly, but the mercury accumulation of fish brain and skin increased significantly. It is recommended that when buying crucian carp, it is best to buy less than half a catty. Such crucian carp is young and has a very low level of methylmercury in its body, so pregnant women and children can eat it with confidence.

Fishskin. As the fish aged, the mercury accumulation in the skin increased significantly, and the mercury content of the skin of the crucian carp was 5 times higher than that of the carp under 200 grams. Fish skin is so much less than fish meat, even if it is a bit of heavy metal, but the total amount is small. I really love to eat fish skin, so it doesn't hurt to eat some in moderation.

Fish blackcoat. Most fish have a black membranous coating on both sides of the abdomen. This membrane coating is the most fishy, earthy-smelling part of the fish, and contains a lot of histamine, lipids and lysozyme.

Accidental ingestion of histamine can cause symptoms such as dizziness, nausea, chest tightness, vomiting, and abdominal pain; Lysozyme has an appetite suppressant effect.

Fish roe. Fish roe contains quite a lot of lecithin, which is helpful for the development of the nervous system, but eating too much is easy to gain weight. Moreover, fish roe is also rich in cholesterol, so people with cardiovascular and cerebrovascular diseases, especially the elderly, must eat less.

If you want to eat fish roe, be sure to cook it thoroughly, and don't overdo it. It should also be noted that some fish roe should not be eaten, such as puffer fish fish roe is highly poisonous, and catfish roe is also poisonous. Accidental ingestion may cause vomiting, abdominal pain, diarrhea, difficulty breathing, etc.

Fishbone. Fish bones and bones are not very different from our bones. The calcium content is very rich, and if you try to mash it, you can still eat it. However, although the amount of calcium in fish bones is large, we can absorb it very limited, and it does not play much role in calcium supplementation.

Peeling the head and skin of the fish can not eat the gills is not only the respiratory organ of the fish, but also a very important detoxification organ, which is also an important reason why people eat fish to remove the gills. Under normal circumstances, there are no toxins present in the fish head, and it is safe to eat the fish head. However, due to the deterioration of the overall environment in recent years, the pollution of water areas and ecological plant chains, coupled with the addition of chemicals to the feed by some farmers, will increase the harmful substances in the fish to a certain extent and be difficult to excrete, which may accumulate in the fish head.

In order to ensure food safety, consumers should try to buy fresh fish and other aquatic products from regular, regulated bazaars, and in addition, eat fish heads in regular restaurants, and try not to order fish heads from roadside stalls.

Ranking of the parts with the highest mercury content: fish head, fish skin, fish meat, and fish roe (try not to eat those with high mercury content).

Taking 400 grams of crucian carp as an example, the mercury content of fish brain reached milligrams, which is 20 times that of fish roe, 15 times that of fish meat, and 6 times that of fish skin. However, this rule does not apply to crucian carp under 200 grams.

Fish "black coat": most fish have a layer of black membrane coating on both sides of the abdomen, which is the most fishy, earthy part of the fishy body, containing a large amount of histamine, lipids and lysozyme, and eating histamine by mistake will cause nausea, vomiting, abdominal pain and other symptoms.

The fishing line can't be eaten, it has to be drawn.

The fish brain of the fish head cannot be eaten, but it is recommended that you do not eat the fish head. The highest mercury content in the body of the fish is the fish head, especially in the polluted water source, if the human body exceeds the mercury standard, it is likely to induce mercury poisoning.

Disadvantages of eating fish heads.

The head of the fish has the highest mercury content on the body, especially if the fish in the polluted water source exceeds the mercury standard, it is likely to induce vertical mercury poisoning. The symptoms of poisoning are dizziness, and in severe cases, coma can be caused. In addition, fish heads are also prone to parasites.

Benefits of eating fish heads.

Fish head is also rich in collagen, and regular consumption can delay skin aging and repair cell tissues. In addition, the fish head is rich in vitamin A, vitamin D and vitamin K. It also contains EPA, a substance that binds to cholesterol in the blood, which can lower cholesterol and prevent cardiovascular disease.

The gills inside the head of a fish are inedible.

The gills are the respiratory organs of the fish, and they are also the detoxification organs of the fish, so the gills must be removed when eating fish, under normal circumstances, there is no problem with eating the head of the fish, but now the water environment is seriously polluted, and some farmers add chemicals to the feed in order to make huge profits, resulting in an increase in the accumulation of toxins in the body of the fish, which may gather in the head, if you eat such a fish head, it may be harmful to the body.

According to relevant medical experts, the overall environment has deteriorated in recent years, leading to water pollution and harmful substances invading the fish. In addition, some farmers add chemicals to the feed, which increases the harmful substances in the fish. These substances are mainly accumulated in fish oil.

Under normal circumstances, the fish head itself is non-toxic and safe to eat. Once there are toxins such as mercury in the fish head, it is mostly caused by environmental pollution or undesirable added components in the breeding process. In addition, it should be pointed out that there are many parasitic residual high worms in the fish head, so you must cook the fish before eating, especially when eating fish hot pot.

If the breeding environment is not contaminated by the bucket, the fish will not have the problem of toxin damage, and the polluted breeding environment often contains long-term pollutants heavy metals, heavy metals are easy to bind to lipids, and the lipid content of the fish brain is higher than that of other parts, which is more likely to accumulate lipophilic methylmercury toxin.

Fish heads are edible.

Such as crucian carp head, squid head, grass carp head, etc., but eat it in moderation, and be sure to choose fresh, unpolluted fish head to ensure adequate cooking.

Fish head contains high-quality protein, lecithin, cholesterol, unsaturated fatty acids, mineral elements and vitamins, etc., and eating it in moderation can help replenish the nutrients needed by the body.

However, there are some fish heads to avoid excessive consumption as much as possible, such as sailfish, tuna and other large deep-sea fish heads, due to long-term survival on the seabed, may accumulate harmful substances in the fish head, fish heads may also contain a lot of heavy metals.

The parts that fish cannot eat are as follows:

1. Fish abdominal black membrane.

Most freshwater fish have a black membrane in their maw, which is known as the "visceral layer of the inner membrane", which lubricates and protects the internal organs of the fish. This membrane has a very high fat content, so it has a strong fishy smell. When fish are contaminated with contaminated water, this black film is contaminated as well.

Therefore, it is best to remove this layer of black film when cleaning fish.

2. Fish gallbladder. Traditional Chinese medicine believes that fish gallbladder is a very good Chinese herbal medicine. Therefore, some friends will feel that eating fish gallbladder has the best effect, and they take it without authorization.

Such an approach is dangerous. The herbs of Chinese medicine are specially treated. Fish gall bladder contains bile toxins, which can lead to poisoning if taken without permission.

Question 7: Why don't you eat fish heads Hello, I'm very happy to answer your question. 1. The head of the fish contains a small amount or even a trace of carcinogenic elements.

2Hairtail fish has many teeth and is very small, and if it is eaten, it may cut through the wall of the esophagus. 3The gills of the head of the hairtail fish are small, unlike carp, etc., and the gills can be cleaned thoroughly, and the dirt in the gills of the hairtail (the accumulation of the hairtail fish when breathing) will remain in the gills. Therefore, it should not be eaten....

I hope mine is helpful to you, hopeful....
