Can you eat sardines while pregnant?
SafeYes, sardines are safe and genuinely great during pregnancy: tiny, low-mercury fish full of omega-3s, calcium and vitamin D. Canned sardines are cooked and ready to eat.
Why
Sardines solve several pregnancy nutrition problems in one small can: they are an FDA Best Choice for low mercury, their soft edible bones deliver calcium, and their oil is rich in the DHA that supports fetal brain development. Because sardines are small and short-lived, they never accumulate the mercury of big predator fish. Canned sardines are fully cooked during processing, making them one of the rare pregnancy-safe seafoods that need zero preparation. As an oily fish, they fall under the NHS's 2 portions a week cap.
Safer alternatives
- Canned salmon
- Cooked fresh mackerel (Atlantic, not king)
- Canned light tuna, within its weekly limits

Frequently asked questions
Are the bones in canned sardines safe to eat?
Yes, and they are a feature: canning softens the bones completely, and they are one of the richest food sources of calcium you can eat. Mash them in and you will not notice them.
Sardines in oil, water or tomato sauce: does it matter?
All are safe; it is purely preference. Olive oil packs carry a few more calories, tomato versions add flavor, water keeps it lean. The fish inside is the same cooked, low-mercury sardine.
Can I eat sardines every day while pregnant?
Better to keep them to about 2 portions a week: sardines are oily fish, which the NHS caps at 2 weekly portions in pregnancy over pollutant buildup. Rotate with white fish and shellfish for the rest of your seafood.
