How much BPA is actually in canned drinks?
Measurable. BPA from can linings leaches into the liquid, especially in acidic drinks.
What's actually in it
The inside of most metal cans is coated with an epoxy lining to prevent the metal from reacting with the food or drink. That lining contains BPA (bisphenol A). BPA is an estrogen-mimicking chemical that the body can confuse for real hormones.
Acidic drinks like sodas, juices, and tomato-based products are worse. The acid helps pull the BPA out of the coating and into the liquid you drink.
What the research says
Researchers in a 2026 study in Molecules measured BPA levels in commercial canned beverages. They found detectable BPA in multiple product types. The levels varied but were consistent with findings from other studies showing that canned beverage consumption raises urinary BPA levels within hours.
Even low doses of BPA matter because the body mistakes it for estrogen. Exposure adds up when you drink multiple canned beverages per day.
Swapping to glass food storage for beverages cuts your BPA exposure significantly. Glass bottles and jars have no lining that can leach into your drink.
