This is because it’s both sweet and low in calories, giving you a sweet taste without negatively affecting your diet. Machiulskiene, Vita; Nyvad, Bente; Baelum, Vibeke (2001).

Bubblegum bubbles are formed when the tension and elasticity of gum polymers acts against the constant and equally dispersed pressure of air being directed into the gum bolus. Bubble gum bubbles are circular because pressure from the focused air being directed into the bolus acts equally on all of the interior surfaces of the gum cud, uniformly pushing outward on all surfaces as the polymers extend. As the bubble expands, the polymers of the gum base stretch and the surface of the bubble begins to thin. When the force of the air being blown into the bubble exceeds the force that the polymers can withstand, the polymers overextend and the bubble pops. Due to the elastic attributes of chewing gum, the deflated bubble recoils and the wad of gum is ready to continue being chewed. [2] a b Bussiere, G.; Serpelloni, M. (1985). Simatos, D.; Multon, J. L.

Swapping your sugary gum for a sugar-free alternative is good for your teeth.

Sugar-free gum contains FODMAPs, which can cause digestive problems in people with IBS.If you’ve been swallowing your gum for years, you can now take a sigh of relief there’s not a great big ball of it just chilling in your intestines. True: You shouldn’t swallow lots of gum This is because sugar is digested by the bad bacteria in your mouth, causing an increase in the amount of plaque on your teeth and tooth decay over time ( 44). However, the overall results are mixed. Some studies have reported that chewing gum does not affect appetite or energy intake over the course of a day ( 34, 35).

A review about the cognitive advantages of chewing gum by Onyper et al. (2011) found strong evidence of improvement for the following cognitive domains: working memory, episodic memory and speed of perception. However the improvements were only evident when chewing took place prior to cognitive testing. The precise mechanism by which gum chewing improves cognitive functioning is however not well understood. Additionally, a study done by Oklahoma State University found that gum is a helpful aid with which to replace nicotine. When smokers were unable to have access to a cigarette during the day, researchers found that chewing gum helped to reduce their cravings. They also didn't smoke as often during the day, and, when they did, they took less puffs from their cigarettes. It makes sense why baseball players are known to turn to gum to cease their nasty chewing tobacco habits, doesn't it? Several studies have demonstrated the benefits of chewing on stress, since Hollingworth [ 138] reported that masticatory movement reduced excessive muscular tension and energy. Soon after the report by Hollingworth, however, foot-tapping was reported to produce the same relaxing effects, suggesting that the stress-reducing effects were not specific to gum chewing [ 139]. Therefore, the benefits of gum chewing on stress remain a matter of debate. The effects of gum chewing on naturally occurring stress are consistently reported to be beneficial. For example, Zibell and Madansky [ 28] investigated whether chewing gum affects perceived levels of everyday stress among subjects who regularly chew gum or among subjects who do not usually chew gum. Stress levels and stress-specific emotions, such as feeling anxiety or tension, decreased after chewing gum, indicating that gum chewing reduces levels of anxiety and stress. Smith [ 29] performed a cross-sectional study of occupational stress in full-time workers and found that non-gum-chewers complained significantly more often of stress at work and home compared with gum chewers, and gum chewers had a lower incidence of high blood pressure. An intervention study revealed that chewing gum reduces occupational stress both at and outside of work, reducing fatigue, anxiety, and depression and leading to a more positive mood [ 29]. Chewing gum is also associated with perceptions of better performance [ 140]. Further, chewing gum is associated in a linear dose-response manner with levels of perceived stress at work and home, as well as anxiety and depression [ 141]. Similar findings were reported for university students [ 142]. Erbay et al. [ 143] examined whether chewing gum is a useful addition to traditional medical treatment of patients with mild to moderate depression and indicated that while chewing gum is not directly effective for elevating a depressed mood, it may reduce the symptoms originating from depression.Other studies [45] indicated that the caries preventive effect of chewing sugar-free gum is related to the chewing process itself rather than being an effect of gum sweeteners or additives, such as polyols and carbamide. A study investigating the in situ effect of casein phosphopeptide–amorphous calcium phosphate (CPP–ACP) found that its incorporation into a sugar-free gum increases the remineralization / protection of eroded enamel surface significantly.
