Betel nut also contains more than 20 kinds of trace elements, of which 1 1 is an essential trace element for human body. Areca seed contains 0.3%-0.6% of total alkaloids, mainly arecoline, and a small amount of arecoline, norarecoline, isonorarecoline, arecoline and homoarecoline, all of which coexist with tannic acid.
Extended data:
Betel nut tastes slightly astringent, slightly sweet and slightly spicy, which can make people feel hot and excited. Therefore, chewing betel nut is addictive, and it has become a traditional custom in the life of local residents in some countries, such as India and the Philippines, as well as parts of China, Taiwan Province Province, Hainan, Yunnan and Hunan.
But chewing betel nut often increases the risk of oral cancer. In 2004, the International Center for Research on Cancer identified betel nut as a first-class carcinogen. Chewing betel nut can easily lead to oral cancer, which is mainly related to the formation of nitroso (carcinogenic compounds) after chewing the chemical substances contained in betel nut, and also related to the mechanical trauma caused by the hardness of betel nut to oral mucosa.
Many investigation data show that regular chewing betel nut is related to the occurrence of oral diseases such as oral submucosal fibrosis, oral cancer, oral leukoplakia, cracked teeth, longitudinal root fracture and so on. In particular, chewing betel nut wrapped in betel nut leaves and ash powder is more likely to increase the risk of cancer.
Proper use of betel nut in clinic can achieve good therapeutic effect. But experts suggest that in order to reduce the risk of oral cancer, the bad habit of chewing betel nut should be changed as much as possible.
