Chewing Gum Consumers - Must Read
# Gum Base: As indicated above, the gum base is rubbery in nature, and used to be derived from latex sap (called chicle) of the sapodilla tree. Other natural sources includegum Arabic, natural resin, food grade agar, Chiku, Ghatti, Jhingan, Khair etc.
However, nowadays, with the advent of rubber synthesis technology, synthetic rubber is primarily used for making the gum base. These include:
- Synthetic resin
- Polyvinyl acetate
- Polyethylene
- Glycerol esters of wood resin/gum resin
- Glycerol esters of partially hydrogenated wood/gum resin
As has been indicated above, there are many components of gum base (besides lanolin) that remain unknown to the consumer, since the manufacturers have no intention to declare them, in the absence of any strict regulations forcing them to do so.
# Softeners: As the name suggests, the primary function of this component is to maintain a "soft" consistency of the gum so that it is appealing to the consumers. This component helps to retain moisture and prevent the gum from hardening. The most common softeners are glycerin and vegetable oil.
# Sweeteners: As you have probably guessed, the most common sweetener is sugar. Sometimes, corn syrup is also used. For the health conscious, the following artificial sweeteners are also used:
- Saccharin sodium
- Sorbitol
- Mannitol
- Xylitol
- Maltitol
- Aspartame (methyl ester)
- Acesulfame potassium
- Sucralose
# Flavours: The flavor component of chewing gum is usually added last and imparts a long-lasting, refreshing, and zingy taste to the chewing gum. Some of the exciting flavors include the following:
- Mint flavored chewing gums
- Fruit flavored chewing gums
What are the Various Varieties of Chewing Gums?
Chewing gums come in a variety of shapes & sizes, attractive wrappers, flavors and a number of novel functions. Some chewing gums are advertised to impart a white sheen to the teeth or for giving kids some fun. Other varieties have medical functions, and contain drugs impregnated in them. These include the following:
- Analgesic e.g. Aspirin
- Antacid e.g. Calcium carbonate
- To increase alertness e.g. Caffeine
- To prevent dental caries e.g. Xylitol or Chlorhexidine
- To give-up smoking e.g. Nicotine
- To provide nutrition e.g. Vitamin C
Hazards:
- Chewing Gum Can Trigger Temporo- Mandibular Joint Disorder (TMD): The temporo-mandibular joint is the joint that connects the jaw bone (mandible) with the temporal bone of the skull. Excessive chewing can cause differential contraction of the muscles, particularly if you chew more with one side of the mouth as opposed to the other. This can trigger TMD, which causes chronic pain, tightening and inflammation of the jaw muscles, ear aches, tooth aches, as well as migraine-type headaches.
Chewing Gum Can Cause Gastrointestinal Problems: Chewing gum increases the air intake into the gastro-intestinal (GI) tract, which can cause abdominal cramps and bloating. It can also aggravate the condition in patients suffering from irritable bowel syndrome (IBS).
Peppermint flavored chewing gum can cause gastric acid reflux. Also, popping a chewing gum into the mouth immediately causes the brain to send signals to the digestive system to be prepared to expect food intake. As a result, saliva and other gastric juices, including gastric acid starts to be secreted. Since, there is no intake of food, this actually may compromise your ability to digest food due to lack of digestive juices, when you actually consume food. This can cause indigestion. Some chewing gum sweetened with artificial sweeteners can cause diarrhea.
- Chewing Gum Can Cause Tooth Decay: Consumption of chewing gum sweetened with sugar essentially coats your teeth with sugar, which leads to tooth decay. Besides tooth decay, dental erosion can also occur. Dental erosion occurs by cumulative decalcification, which slowly erodes the teeth. This can occur even in the presence of artificial sweeteners, since they contain acidic flavorings and preservatives that can erode the teeth, in spite of the presence of xylitol that fights cavities.
- Chewing Gum Can Release Mercury from Dental Fillings: Amalgamated dental fillings typically contain silver, mercury and tin. Chewing releases mercury vapors from the fillings, which can be rapidly absorbed into the blood. Although the amount of mercury is minute, you wouldn't want to contaminate your system with mercury, however small.
The foregoing discussion highlights the composition, varieties and health hazards of chewing gums. Although primarily the deleterious effects of chewing gums have been highlighted, it may be added that chewing a piece of gum after a meal could be a healthy habit - the saliva released helps to clean the teeth and the flavor can add freshness to the breath! more
