• Aspartame
    1. The artificial sweetener aspartame is metabolized inside your body into both wood alcohol (a poison) and formaldehyde (which is a carcinogen used as embalming fluid and is not eliminated from your body through the normal waste filtering done by your liver and kidneys). It's been linked to birth defects, cancers, brain tumors and weight gain.
  • BHT (Butylated Hydroxytoluene)
    1. 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.
  • Calcium Casein Peptone (Calcium Phosphate)
    1. 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.
  • Gum Base
    1. It's quite a mystery what 'gum base' is actually made out of, but the investigators found it's usually a blend of synthetic 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, which is linked to cancer.
  • Titanium Dioxide
    1. Titanium dioxide is often used as a color agent in chewing gum, but it's been linked to autoimmune disorders, asthma, and Crohn's disease and is potentially carcinogenic. One study found children are highly exposed to titanium dioxide in confections, with chewing gum containing the highest levels.
