While tinned fish is nutritious, there are a few health considerations to keep in mind.
Mercury
Fish and shellfish—such as swordfish, mackerel, and tuna—may contain mercury. Exposure to high levels of mercury can cause:
- Impaired brain development and function
- Cardiovascular disease
- Impaired fetal growth
Pregnant people and young children should avoid excessive mercury intake.
Sodium
Tinned fish can be salty. To avoid the adverse effects of excessive sodium intake, check labels for low-sodium options and be mindful of portion sizes.
When shopping for canned fish or shellfish, it’s best to purchase:
- Low mercury options, like sardines, salmon, and trout
- Low-sodium options (read the label to ensure there is no added salt)
- Sustainably-produced options, such as those certified by the Marine Stewardship Council or other organizations that set standards for sustainable fishing
