Artificial sweeteners are only one reason to avoid chewing gum. Most brands also contain additional chemical ingredients that do not belong in your body. There are natural chewing gum brands on the market that do not contain these questionable ingredients, so if you must chew gum, look for these. However, keep in mind that even natural chewing gum will pose risks from excess chewing, including TMJ, digestive issues, and more.
1. BHT (Butylated Hydroxytoluene)
BHT is so toxic it’s already been banned in many other countries. In the US, it’s often used as a preservative in chewing gum and other processed foods. BHT has been linked to organ system toxicity, including kidney and liver damage, hyperactivity in children, and may be carcinogenic.
2. Calcium Casein Peptone (Calcium Phosphate)
Found primarily in Trident gum, it’s thought this ingredient may be used as a whitening agent or texturizer. As a highly processed milk derivative, little is known about its long-term ingestion, although casein was previously linked to baby formula poisonings in China and is a well-recognized trigger of autoimmunity.
3. Gum Base
It’s quite a mystery what “gum base” is actually made out of, but the investigators found it’s usually a blend of elastomers, resins, plasticizers, and fillers. Most manufacturers do not reveal more specifics than this. After all, why would they want you to know that you’re potentially chewing on petroleum-derived paraffin wax, polyvinyl acetate (carpenter’s glue) and talc, all of which are linked to cancer.
4. Titanium Dioxide
Titanium dioxide is often used as a whitening agent in chewing gum, but it’s been linked to autoimmune disorders, asthma, and Crohn’s disease and is potentially carcinogenic – especially in its nanoparticle form. One study found children are highly exposed to titanium dioxide in confections, with chewing gum containing the highest levels.
