Risk of betel
nut chewing
This nut is chewed regularly by at least 10% of the world population, imported by immigrant users wherever they settle, and is the fourth most widely used addictive substance. It is thought, by users, to soothe the digestion and to be a stimulant and its use has a major role in social situations. Specific arecal alkaloids act as competitive inhibitors of GABA receptors and have widespread effects in the body, including actions on the brain, cardiovascular system, lungs, gut and pancreas.
Nitro sated derivatives of arecal alkaloids, proven carcinogens inducing tumors throughout the upper gut and foregut derivatives in animals, are also associated with increased tumor risks in man. Increased central obesity is found in association with betel usage in man as well as increases in circulating markers of inflammatory and cardiovascular damage. The effects of chronic betel usage in man are at least as diverse as those of smoking and the habit increases the risks of ill health.
Betel Nut and Oral Cancer
Betel quid chewing is a strong independent risk factor for pharyngeal cancer (cancer of the back of the throat), but not laryngeal cancer (cancer of the voice box), according to findings published in the International Journal of Cancer. Chewing betel quid, which consists of betel leaf from the Piper betle vine, is popular in many parts of Asia. Betel quid is chewed for its stimulant effects, to satisfy hunger and as a social and cultural practice.
