The Best Plastic-Free Chewing Gums
The Hidden Health Risks of Standard Plastic Chewing Gum
Many commercial chewing gums use a base made of synthetic polymers—essentially plastics like polyethylene and polyvinyl acetate. While these materials are approved for use, concerns about their long-term effects on health are growing. Here’s what you need to know
Microplastics in Your System
Chewing gum made with synthetic plastic bases may introduce microplastics into your body. While studies are still ongoing, early evidence suggests microplastics can:
- Accumulate in the body: Microplastics have been found in human blood, organs, and even breast milk, raising concerns about their long-term health impact.
- Damage the gut microbiome: Ingested microplastics may disrupt the balance of gut bacteria, which is essential for digestion, immunity, and overall health.
- Trigger inflammation: Research suggests microplastics can cause chronic inflammation, potentially contributing to conditions like inflammatory bowel disease and other systemic issues.
