Welcome to the world of funny conversations, health and fish!
Fish is a precious ingredient given by nature to mankind, it is not only delicious, but also nutritious, and is one of the important sources of nutrients that the human body needs. The fish has a unique delicious taste in the taste. The fish meat is delicate in texture and delicious, and it is not only salty and delicious, but also fresh and refreshing, and is one of the delicious dishes loved by the broad masses of the people.
Secondly, fish is rich in a variety of nutrients and plays an important role in human health. Fish is rich in high-quality protein, the human body has a high absorption and utilization rate, and can provide the necessary amino acids needed by the body, but there are studies that show that fish causes cancer, is this true?
First, American research: fish contains carcinogens, eat more or harmful?
The claim that eating fish may cause cancer comes from a U.S. study that surveyed more than 490,000 U.S. adults and found that eating more fish like tuna and non-fried fish was more likely to develop melanoma. The researchers believe that this may be related to contaminants in fish, and the higher the fish intake, the more pollutants accumulate.
However, this is only an observational study and does not prove cause and effect, and the study authors themselves say that changing fish consumption is not recommended. You know, fish is rich in protein, which is not only easy to digest and absorb, but also provides essential nutrients for the human body.
Moreover, fish meat is also rich in omega-3 polyunsaturated fatty acids, which have various effects such as preventing cardiovascular and cerebrovascular diseases, lowering cholesterol, and anti-inflammatory. Therefore, it is good for us to eat fish in moderation every day, but it can also bring some risks if it is not eaten properly.
Secondly, organic mercury contained in fish is a problem that we need to pay attention to, organic mercury is a toxic metal element, if the human body ingests too much, it will cause damage to the central nervous system, and long-term intake of too much organic mercury will increase the risk of cancer.
Therefore, when we choose fish, we should pay attention to choosing fish with low mercury content, such as sea bass, bonito, salmon, etc. In short, fish is not a carcinogen, but you need to pay attention to choosing the appropriate type and processing method when eating.
If we can eat fish correctly, it will not only provide the body with essential nutrients, but also prevent many diseases, which is a very healthy food.
Second, the real carcinogen is these 4 species of fish
Salted fish
Many people have a soft spot for salted fish and like to eat it often, but what some people don't know is that salted fish is a "first-class carcinogen". The reason is that in the process of salting salted fish, a large amount of table salt is used, which leads to the production of nitrite.
Nitrosamines are very carcinogenic, long-term consumption will induce cancer, such as esophageal cancer, liver cancer, etc., salted fish in the production, will also add a lot of salt, long-term excessive consumption of salt, but also increase the incidence of gastrointestinal diseases.
Salted fish is also prone to mildew, and bacteria can easily enter the fish meat, causing the fish meat to deteriorate, and mildew occurs. Moreover, nitrite will become nitrosamines after entering the stomach, and if eaten regularly, it may increase the risk of esophageal cancer, stomach cancer, liver cancer, and bowel cancer.
Fish
Smoked fish is a food made from fresh fish, and in the process of preparation, fresh fish is first washed and marinated, and nitrite may be produced in this process.
Secondly, in the process of smoking fish with charcoal or other methods, a large amount of benzopyrene will be attached to the surface of the fish, which is a strong carcinogenic substance. Although smoked fish is not a particularly healthy food, it also contains protein, vitamin E, minerals and other elements, and it is recommended to eat it no more than 2 times a month.
herring
Bluefish is a common marine fish with delicious meat and rich nutrients, however, bluefish is also a carcinogenic fish. Blue fish often contain a substance called nitrite, which is converted into nitrosamines under the action of stomach acid.
Nitrosamines are a very carcinogenic substance, long-term consumption of food containing nitrite will increase the risk of cancer in humans, so blue fish should be eaten in moderation.
whiting
Cod is a common saltwater fish with tender meat and delicious taste, which is a favorite ingredient for many people. However, cod is also a carcinogenic fish. Cod often contains substances called cholesterol oxidation products, which accumulate in the cod.
Over time, cholesterol oxidation products are a highly carcinogenic substance. Long-term consumption of foods containing cholesterol oxidation products increases the risk of cancer in the body.
