- The bottom line
The ingredients in chewing gum are safe for people to consume, and the act of chewing may even have mental and physical health benefits. However, some people get jaw pain or headaches from chewing.
People have been chewing gum in various forms for thousands of years.
The first gums were made from the sap of trees, such as spruce or Manilkara chicle.
However, most modern chewing gums are made from synthetic rubbers.
Chewing gum is a soft, rubbery substance that’s designed to be chewed but not swallowed.
Recipes can vary among brands, but all chewing gums have the following basic ingredients:
•Gum. This is the nondigestible, rubbery base used to give gum its chewy quality.
•Resin: This is usually added to strengthen gum and hold it together.
•Fillers. Fillers, such as calcium carbonate or talc, are used to give gum texture.
•Preservatives. These are added to extend shelf life. The most popular choice is an organic compound called butylated hydroxytoluene (BHT).
Butylated hydroxytoluene (BHT)
BHT is an antioxidant that’s added to many processed foods as a preservative. It stops food from going bad by preventing fats from becoming rancid. Its use is controversial, as some animal studies suggest that high doses can cause cancer. However, the results are mixed, and other studies haven’t found this effect (1, 2). Overall, there are very few human studies, so BHT’s effects on people are relatively unknown. However, a Dutch study from 2000 assessed the connection between BHT and stomach cancer and found that men and women who consumed BHT in usual amounts had no increased risk (3). Both the FDA and the EFSA have deemed BHT generally safe in low doses of around 0.11 mg per pound of body weight (0.25 mg per kg) (4). It appears that most people consume far less than this recommended level. One study that analyzed urine samples from multiple countries estimated that the average daily intake of BHT in adults was only 0.21–31.3 micrograms per kg of body weight (5).
Titanium dioxide
Titanium dioxide is a common food additive used to whiten products and give them a smooth texture. Some older animal studies have linked very high doses of titanium dioxide with nervous system and organ damage in rats (6, 7). Inflammation, oxidative stress, and cancer have also been observed in studies that have treated rats with titanium dioxide (8). Research has yet to determine the amount of titanium dioxide that might be harmful in humans. At the moment, the amount and type of titanium dioxide people are exposed to in food is generally considered safe. Nevertheless, more research is needed to determine the safe consumption limit (9, 10, 11).
Aspartame
Aspartame is an artificial sweetener commonly found in sugar-free foods. It’s highly controversial and has been claimed to cause a range of conditions, from headaches to obesity to cancer. Animal studies have suggested that aspartame is a chemical carcinogen in rodents and that prenatal exposure to aspartame increases cancer risk in rodent offspring (12). However, the possible connection between aspartame and obesity needs to be further studied (13, 14). According to the FDA, consuming amounts of aspartame that are within the daily intake recommendations isn’t thought to be harmful (15). However, people who have a rare hereditary condition known as phenylketonuria should limit their consumption of phenylalanine, which is a component of aspartame (15).
Studies have found that chewing gum while performing tasks can improve various aspects of brain function, including alertness, memory, understanding, and decision making (21, 22, 23, 24, 25).
One randomized controlled trial found that students who chewed gum over a period of 7 or 19 days had reduced scores for depression, anxiety, and stress compared to those who did not. Those who chewed gum also achieved greater academic success (26).
Interestingly, some studies have found that chewing gum during tasks may be a bit of a distraction at the start but could help you focus for longer periods (27).
Other studies have found benefits during only the first 15–20 minutes of a task (28).
Experts don’t fully understand how chewing gum improves memory. One theory is that this improvement is due to increased blood flow to the brain caused by chewing gum.
Studies have also found that chewing gum may reduce stress and increase feelings of alertness (22, 29, 30).
Chewing gum could be a helpful tool for those trying to lose weight.
This is because it’s both sweet and low in calories, giving you a sweet taste without negatively affecting your diet.
Some research also suggests that chewing gum could reduce your appetite, which could prevent you from overeating (35, 36).
One small study found that chewing gum between meals decreased feelings of hunger and reduced intake of high carb snacks in the afternoon (37).
The results of another small study suggest that chewing gum while walking could help burn more calories (38).
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 (39, 40).
Chewing sugar-free gum could help protect your teeth from cavities.
It’s better for your teeth than regular, sugar-sweetened gum. This is because sugar feeds the “bad” bacteria in your mouth, which can damage your teeth.
However, some sugar-free gums are better than others when it comes to your dental health.
Studies have found that chewing gums sweetened with the sugar alcohol xylitol are more effective than other sugar-free gums at preventing tooth decay (43).
This is because xylitol prevents the growth of the bacteria that cause tooth decay and bad breath (44, 45).
In fact, one study found that chewing xylitol-sweetened gum reduced the amount of bad bacteria in the mouth by up to 75% (46).
Sugar-free gums contain laxatives and FODMAPs
The sugar alcohols used to sweeten sugar-free gum have a laxative effect when consumed in large amounts. This means that chewing lots of sugar-free gum could cause digestive distress and diarrhea (48). Additionally, all sugar alcohols are FODMAPs, which can cause digestive problems for people with irritable bowel syndrome (IBS).
Sugar-sweetened gum is bad for your dental and metabolic health
Chewing gum sweetened with sugar is really bad for your teeth. 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 (49). Eating too much sugar is also associated with a number of health conditions such as obesity, insulin resistance, and diabetes (50).
Chewing gum too often could cause problems with your jaw
Constant chewing could lead to a jaw problem called temporomandibular disorder (TMD), which causes pain when you chew. Although this condition is rare, some studies have found a link between excessive chewing and TMD (51, 52).
If you like chewing gum, it’s best to choose a sugar-free gum made with xylitol.
The main exception to this rule is for people with IBS. Sugar-free gum contains FODMAPs, which can cause digestive problems in people with IBS.
Those who can’t tolerate FODMAPs should choose a gum sweetened with a low calorie sweetener such as stevia.
Make sure to read the ingredient list on your gum to confirm that it doesn’t contain any ingredients you have an intolerance to. Check in with a dentist or dietitian for help deciding which type of gum is best for you.
The ingredients in chewing gum have been established as safe for humans to consume. In fact, the act of chewing may have surprising benefits for mental and physical health!
However, some people may find that they experience adverse side effects, such as jaw pain or headaches, from chewing gum. If you know this habit causes you problems, it’s best to limit your chewing. Otherwise, a stick or two of gum between meals isn’t a bad idea.
Apr 16, 2023 · Even if the ingredients agree with you, you also gulp and swallow more air as you chew. "Excess air can cause more unwanted belching and bloating," Mitri says. However, on the bright side, she also notes that chewing gum may release enzymes and bile into your digestive tract, which can enhance digestion for some.
According to the U.S. Food and Drug Administration (FDA), chewing gum is considered a food, as the term "food" means "a raw, cooked, or processed edible substance, ice, beverage, or ingredient used or intended for use or for sale in whole or in part for human consumption, or chewing gum". [60]
