Smoked fish is a kind of "fried fish" in southern cuisine, which is mainly a kind of "fish food" obtained by soaking fried fish pieces in marinade. Some people think that smoked fish is directly smoked fish, and most online comments refer to this kind of smoked fish. This kind of smoked fish is also called "China salted fish" by many people.

It is reported that benzopyrene contained in smoked fish is a "carcinogen". Both smoked fish and salted fish actually represent "pickled fish food". Salted fish has also been listed as a "class I carcinogen" by relevant institutions (substances that are clearly carcinogenic to human body), and eating more will indeed increase the risk of cancer. However, the concept of "quantity" should be considered in any toxic and carcinogenic reactions. Although there is a cancer risk, it does not mean that it is completely inedible.

First of all, for "smoked fish", whether it is smoked directly or fried, it is indeed possible to produce carcinogen benzopyrene under the condition of high temperature cooking. However, it cannot be directly judged that "one kilogram of smoked fish is equivalent to 250 cigarettes", because the smoking degree (duration) and processing time of smoked fish are different, and the dose of benzopyrene contained in it is also very different.

And smoked fish is not a very healthy food, but it contains protein, vitamin E, mineral zinc and other healthy nutrients. Secondly, there are no substances or ingredients beneficial to health in cigarettes, not to mention more than 20 kinds of harmful substances such as polycyclic aromatic hydrocarbons, nicotine, nitrosamines, volatile ketones and aldehydes, which are not as good as smoked fish containing nutrients such as protein.
