To maintain freshness, some gum brands add butylated hydroxytoluene (BHT), a preservative known for its antioxidant properties. The FDA deems BHT safe in small amounts, but studies in animals have associated high doses with cancer. Although the levels in gum are low, BHT’s reputation still raises concerns for some consumers.
Chewing gum excessively can lead to other health issues, such as temporomandibular joint disorder (TMJ), which affects the jaw joint connecting to the skull. TMJ can cause pain, migraines, and earaches, and over-chewing has been noted as a headache trigger, especially in children and teens. This highlights the importance of moderation for gum enthusiasts.
For those seeking more natural options, some brands use plant-based ingredients. Chicle, once the original gum base, is still used by a few natural brands. Another alternative under research is corn zein, a protein from corn that offers similar chewiness without synthetic materials. Though less common, these natural options appeal to consumers looking for plant-derived gum bases.
One popular myth claims that swallowed gum builds up in the stomach, but this has been debunked. Despite its resistance to digestion, gum passes through the digestive system like other indigestible items. As BBC Science Focus explains, swallowed gum “eventually continues its merry way along your digestive tract,” leaving the body naturally. So, while some ingredients may raise concerns, swallowing gum poses no real harm.
For many, learning about what’s in chewing gum has been eye-opening. From rubber-like components to sheep-derived wax, these ingredients underscore the surprising choices made by manufacturers. Although these ingredients are considered safe, many consumers now seek natural alternatives. Whether this knowledge makes you reconsider or inspires you to try plant-based gum, it serves as a reminder to look more closely at what’s inside our favorite products.
