The harm is certain, but whether it causes cancer varies from person to person, just like smoking causes cancer, but not everyone who smokes will suffer from cancer; If you don't have to eat it, it's recommended to eat it in moderation. It's totally okay to eat it in moderation ... For example, it's the custom in southwest China to smoke meat during the Spring Festival. After eating it for so many years, the incidence of cancer in Sichuan and other places has not been higher than that in other areas. Therefore, please rest assured that a small amount of moderate consumption.
