Fish is a good food. It’s a good source of protein, low in fat, and contains unsaturated fatty acids. Chinese people are deficient in vitamin D, selenium and other nutrients, which are also abundant in fish. Xiaobian also especially like to eat fish, but also eat not to gain weight
Dietary Guidelines for Chinese residents suggest eating 280 to 525 grams of fish per week.
But you know what? Because of water pollution, fish tend to accumulate heavy metals, such as methylmercury, a heavy metal pollutant typically ingested by fish. It mainly invades the central nervous system and can cause language and memory disorders.
A place on the fish body must not touch, it is more poisonous than arsenic, still have 4 places, must eat less, had better not eat again from today!
- The gall bladder
Rumors have been circulating about eating fish gall bladders for medical treatment, but the truth is that many fish gall bladders are poisonous. A 51-year-old man in Hunan province, Surnamed Shi, nearly died after eating seven fish gall bladders raw according to the Xiaoxiang Morning Herald. Such things happen all over the place.
Changsha first, chief physician, director of the hospital emergency department LiJun introduction, fish bile poisoning almost no suspense, black carp, grass carp, silver carp, bass, carp and other freshwater fish, the fish bile contains highly toxic bile toxin, because of bile poison not easily damaged by heat and ethanol (alcohol), therefore, no matter to swallow, food or wine send clothes, adult feeding more than 2.5 grams, will most likely lead to poisoning, even make people die. A fish of 1-2 kilograms can achieve, or even exceed, this dose.
Important things say three times: fish gall never eat! Never eat fish gall! Never eat fish gall! Grass carp, carp, dace, herring, crucian carp, silver carp and bighead carp, don’t eat, the farther away the better!
In addition, when cleaning the fish viscera, must remove the fish gallbladder. If it breaks by accident, be sure to wash it thoroughly and be careful not to get the juice into your eyes.
- The fish head
The idea of eating fish head for brain is also very popular in the folk, fish head meat is a lot of people’s heart, just looking at a dish of minced pepper fish head straight saliva. But in fact, this is the same as eating fish eyes, are not reliable “shape to shape” fantasy, fish head had better eat less, fish head is generally easier to accumulate heavy metals, children should not eat for a long time.
This is supported by research data. Nanjing Center for Disease Control and Prevention studied the most common carp in supermarkets and farmers’ markets:
The results showed that the mercury content of carp, roe, skin and brain of carp below 200 grams was very low, and the difference was not obvious. They were all lower than 0.02 mg/kg, far below the national limit (Hg≤0.5 mg/kg), so they could be safely eaten.
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.
The mercury content in the skin and brain of 350 grams of crucian carp increased slightly. The mercury content in the skin of 400g crucian carp is five times higher than that in the skin of 200g crucian carp, and the mercury content in the brain of carp is more than 20 times higher.
Proposal in the purchase of crucian carp, it is best to buy half catty below. Such crucian carp age is small, the methyl mercury content in the body is very low, pregnant women and children can be assured to eat.
If you buy more than seven carp, also do not worry, because under normal circumstances the fish and roe are very safe, but it is best not to eat fish head.
- The fish skin
The experimental results just showed that with the increase of fish age, the mercury accumulation of fish skin increased significantly, and the mercury content of carp skin of 400 grams was 5 times more than that of carp of 200 grams or less.
Nevertheless, fish skin is less than fish so much, calculate a bit heavy metal, but total amount is little, love to eat fish skin really, right amount eats some just as well.
- The fish in black
Most fish have a black membrane coating on both sides of their abdomen. This membrane coating is the most smelly and earthy part in the fish, and contains a large amount of histamine, lipids and lysozyme. Eating histamine can cause dizziness, nausea, chest distress, vomiting, abdominal pain and other symptoms. Lysozyme has an inhibitory effect on appetite.
In Shenzhen, 26 people were poisoned by mackerel eaten by histamine, shenzhen News reported.
- Fish roe
Fish seeds contain a lot of lecithin, which helps the development of the nervous system, but eating too much is easy to get fat. Besides, fish roe is also rich in cholesterol, so people suffering from cardiovascular and cerebrovascular diseases, especially the elderly, must eat less.
Although the roe is small, it is difficult to cook it thoroughly, and it is easy to cause indigestion after eating. Therefore, if you want to eat fish roe, be sure to cook thoroughly, and do not eat too much.
It should also be noted that some fish roe should not be eaten, such as pufferfish roe is highly toxic, catfish roe is also toxic, accidental ingestion may cause vomiting, abdominal pain, diarrhea, breathing difficulties and so on.
- Barb
One might think to oneself that one does not need an expert to remind one that one is too stupid to eat a fish bone. ? That’s a lot! Because someone says fish bone calcium content is rich, ate can fill calcium ah.
However, fish bone is probably the most annoying part of eating fish, both not delicious, but also easy to stick, really uncomfortable, especially children, once stuck and may even endanger life. The calcium was not worth the risk. The fish bone stuck in the throat was not worth the risk.
Fish bones and bones are not very different from our bones. They are rich in calcium and can be eaten if mashed as much as possible. However, although there is a lot of calcium in fish bones, we can only absorb it so much that we can’t do much to supplement it. To get calcium, drinking a glass of milk is much stronger and more comfortable than eating fish bones.
How to eat fish healthier?
Frying and braising generally use more oil, and roasting at a high temperature tends to produce more PAHs. But baking in the oven, which uses less oil, is also a good way, and steaming is probably the best way to cook.
It is better to eat fish after it is cooked and heated, which can kill possible pathogenic bacteria, parasites and so on.
The older a fish is, the more mercury accumulates in its brain and skin. When eating fish, fish head and skin must eat less, or even do not eat! Fish gall is naturally never eat!
