Is it safe for couples trying to conceive to use BPA-free canned food?
Use caution. BPA-free does not always tell you what replaced BPA.
Short answer
Use caution with a daily canned-food habit while trying to conceive. A BPA-free label is better than BPA, but it does not always tell you the full liner chemistry. For foods you eat often, glass, frozen, or dried options are better picks.
What is in the can
Metal cans need a liner so food does not react with the metal. Older can liners often used BPA-based epoxy. Some newer liners use other materials. The label may not explain the liner in enough detail for shoppers to compare one can with another.
What the research says
A 2026 Environmental Health study measured urinary BPA and newer bisphenols in couples before conception. Higher mixed bisphenol exposure was linked with longer time to pregnancy. The study measured body burden, not cans alone.
A 2019 Environmental Science and Pollution Research crossover study found urinary BPA rose after canned food intake compared with fresh food intake. Mean BPA levels were higher 2, 4, and 6 hours after canned meals.
What to do
For the 3 months before trying to conceive, make the easy swaps first. Use dried beans instead of canned beans. Choose tomato sauce in glass jars when you can. Pick frozen vegetables instead of canned vegetables. After opening glass-packaged foods or batch-cooking beans, store leftovers in glass.
