The harm of betel nut
Let's start with a set of data. In Oceania, there is a country called Papua New Guinea. With a total population of 7 million, more than 60% people like to chew betel nut. It has become a normal state for people to chew betel nut in the street. Some people may think this is nothing. However, the incidence of oral cancer in Papua New Guinea is as high as 2 per thousand, which means that in a country with a population of 7 million, more than 10,000 people suffer from oral cancer every year, which is caused by a large number of people who like to chew betel nut for a long time. Areca catechu was listed as a first-class carcinogen by the World Health Organization in 2004. However, this has not affected people's love for betel nut. Among them, it took less than 10 years for China to become a betel nut country directly, and the incidence of oral cancer in China also rose sharply during this period. During the period when China people were crazy about eat areca, there were more than 60 million people in China who suffered from oral diseases because of long-term eat areca, and this oral disease was a precursor of oral cancer. During this period, China, Hunan and other places were crazy about betel nut. Here, betel nut has become a must-have snack for every family, and almost no one does not chew betel nut. As a result of this crazy love, the incidence of oral cancer in Hunan directly exceeds the national average by more than 30%. Even though most people are aware of the dangers of frequent eat areca, they are still lucky. Many people even come out and say that it's okay for me to chew betel nuts all my life. Faced with this kind of rhetoric, it is easy for people to choose to believe it, and they will not know their regrets until oral diseases really happen to them. So how does betel nut cause cancer?
Destroy one's mouth
Do you know any patients with oral cancer? In order to cure oral cancer, these people will be removed from the part of their faces where cancer cells exist, which may be the tongue, chin, gums, or even half of their faces. The scene is horrible, and these people will become non-people, ghosts are not ghosts, because it is so horrible that we won't let everyone see it here. If you are interested, you can search for it yourself. One of the reasons for the high incidence of oral cancer is betel nut chewed in people's mouths. I don't know if you have heard of arsenic trioxide, also known as arsenic. It is a highly toxic inorganic compound. Betel nut contains this variety, because some manufacturers smoke betel nut with coal soil, which not only has low cost, but also tastes better. However, many people who love to eat don't know that while immersed in betel nut, they don't know that they have taken poison. However, the arsenic trioxide content in betel nut will not cause poisoning death, but it will still do some harm to your mouth and body. What about pure industrial betel nut? Pure industrial betel nut contains very little arsenic trioxide, which is almost harmless to human body, but in the process of chewing betel nut, another harmful substance-nitroso compound will be produced. Nitroso compounds are old friends of carcinogens, and almost all carcinogens have their shadows. But it is still difficult to get oral cancer with this substance alone. After all, people's mouth has a self-protection system, but because betel nut is hard, it will cause harm to the mouth when chewing. At this time, nitroso compounds will take advantage of it, thus greatly increasing the chances of people suffering from oral cancer. And these are actually just one of the hazards of betel nut. The harm of betel nut to oral cavity is far beyond your imagination!
