Health dangers of betel nut | Side effect of betel nut


Betel nut holds a key position in several Asian cultures where it is consumed dried, fresh or wrapped in a ‘Paan’ almost every day by a large number of people. Although the exact preparation varies across Asia and even within each country, paan usually contains slaked lime, betel leaf, cardamom, cinnamon and tobacco.  While betel holds a key place in these regions, it is also a root cause of worry for several researchers. 

The International Agency for Research on Cancer has associated almost all of the ingredients of paan, except cardamom and cinnamon, as cancer-causing agents with betel nut being at the top of the list. The World Health Organization has even classified betel nut as a carcinogen.
