Glass Bottles May Be Flooding Your Drink With Plastic.

A 2025 French study from ANSES found that glass-bottled beverages—like soda, lemonade, iced tea, and beer—contain around 100 microplastic particles per liter, which is 5 to 50 times more than plastic or metal bottles.

The culprit? It isn’t the glass—it’s the paint on the metal caps. Tiny scratches during bottling and storage release plastic particles that contaminate your beverage. Surprisingly, even “safer” glass doesn’t protect you from this invisible threat.

For those unaware, microplastics are already linked to inflammation, hormone disruption, DNA damage, respiratory issues, heart disease, and some cancers.

Rinse or blow off bottle caps to reduce exposure by up to 60%, or better yet, skip bottled beverages altogether—your body doesn’t need hidden plastic.
