Yes, in moderation. Canned light tuna is a good low-mercury choice; limit albacore and fresh tuna steaks because they contain more mercury.
Why
- Fish provides omega-3 fats that support the baby's brain development — eating some fish is encouraged.
- The FDA lists canned light tuna as a 'best choice' and albacore/yellowfin as 'good choice' (one serving per week).
How to eat it safely
- Up to 2–3 servings a week of low-mercury fish, including canned light tuna.
- Cook fresh tuna thoroughly unless it was frozen before eating raw (UK guidance).
Safer alternatives
- Salmon
- Sardines
- Cod
