Is drinking from glass safer than cans or plastic bottles?
Cans can be a BPA source because many use epoxy linings. This study found higher urinary BPA after canned soda than after PET bottles, but it did not prove one package is always safest.
What the study looked at
A 2025 randomized crossover trial followed 103 women who drank the same soda from cans, PET plastic bottles, and glass bottles. The researchers measured bisphenols in urine two to three hours later.
They found urinary BPA was 22.3% higher after canned soda than after PET bottles. They also found BPF, BPS, and BPE at lower levels in some samples. Blood pressure rose after soda in all groups, which the authors said was likely tied to caffeine, not the package.
So is glass safest?
The study supports being careful with canned drinks because can linings can add BPA exposure. It does not prove glass always beats every other package in every setting. Packaging, lining, product type, and brand choices all matter.
What to do
When you have a choice, use simple glass cups or jars at home. Limit canned drinks when easy, especially for pregnant people and kids. Do not assume a BPA-free label means no bisphenol exposure, because related bisphenols can also show up.
Bottom line
Glass is a simple material for home drinkware. For packaged drinks, this study gives the clearest caution signal for cans, not a perfect ranking for every bottle type.
