Is it safe for couples trying to conceive to use BPA-free canned food?

What's actually in it

Canned beans, tomatoes, soup, and fish sit in a thin plastic epoxy liner that keeps the metal can from corroding. The original epoxy was a BPA-based resin. Most brands moved to "BPA-free" liners when consumer pressure mounted. The replacements are usually BPS, BPF, or acrylic. All of them leach at some rate into the food, and acidic foods (tomatoes, pineapple) pull more than neutral ones.

Couples trying to conceive care about exposure in the three months before conception, because sperm and eggs both take roughly that long to mature.

What the research says

A 2026 study in Environ Health measured urinary BPA and emerging substitutes in preconception couples and then tracked how long it took them to conceive. Higher total bisphenol load (original BPA plus the newer replacements) was associated with subfecundity: longer time to pregnancy. The replacements hit the same endpoints as BPA. "BPA-free" on a can label did not protect fecundity.

The workaround is to shift to glass jars, dry goods, and frozen versions for the three months before trying. Dried beans soaked overnight replace canned beans and cost less. Glass-jarred tomato products replace cans for sauce. Pouch-packaged fish replaces canned tuna. Fresh and frozen produce replaces canned vegetables. For the foods that really need to be canned, brands that use non-bisphenol liners (some say "oleoresin-lined" or "plant-based liner") are a smaller upgrade.
