What Is Chewing Gum Made Of?
Chewing gum is mostly made of plastic. Polymers such as polyvinyl acetate can make up nearly 60% of most gums. Alongside this, manufacturers often add fillers, waxes, and emulsifiers to create texture and stability.
Why Is Chewing Gum Sweet?
The sweetness in gum usually comes from sugar alcohols and artificial sweeteners. These additives are common but not always ideal:
- Xylitol – Often used in toothpaste and mouthwash, but less desirable when swallowed in chewing gum.
- Aspartame – An artificial sweetener that can negatively affect the gut microbiome.
Preservatives and Additives
Many chewing gums also contain preservatives. One of the most common is BHT (butylated hydroxytoluene). While evidence in humans is inconclusive, studies in rats have shown carcinogenic effects. BHT may also impair blood clotting and act as an endocrine disruptor.
Flavors in Gum
Flavors can be labeled as “natural” or artificial, but neither type is ideal when added to gum. These flavorings contribute to the product’s appeal without offering meaningful benefits.
Bottom line: Chewing gum isn’t as harmless as it seems. From plastics and sweeteners to preservatives and flavorings, knowing what’s really inside your gum helps you make more informed choices.
