Knowing how to use fire is a sign of human progress. Humans are not afraid of fire and can cook all kinds of food with fire. However, after social progress, people prefer raw food, such as sashimi and raw pickles. There is nothing wrong with liking a certain food, and others have no right to question that adults are responsible for their own health. There are many parasites in raw food. Fire can kill these parasites and won't make you parasitic. It can only be said that people who like to eat raw pickles are very courageous, and may also use pesticides or go to the hospital for regular checkups, otherwise it is difficult to guarantee their health.
The common way to pickle things is to add some special seasonings, and sometimes add some fruit juice, such as lemon juice. This food tastes really fresh. If it is just caught seafood, it will produce a special taste after pickling, and people can't help falling in love with it. Some people are cautious and will use high-concentration liquor, but it is useless to do so, and they still can't kill parasites. For example, a woman pickled crabs with high-alcohol liquor on the Internet. As a result, she got drunk after dinner with her friends. It can be seen that crabs are really delicious. However, the parasite eggs inside may not be completely killed, but will become real bugs after being hatched by the human body.
For the sake of health, you can try to eat less raw and salty food or have regular physical examination.
