Potential Risks and Considerations

While tuna offers many benefits, there are some factors to consider:

Mercury Content: Larger tuna species like albacore and bluefin can contain higher mercury levels, which may pose risks if consumed excessively.
Sodium Levels: Canned tuna can be high in sodium, which may affect blood pressure if eaten frequently.

Recommendations for Safe Consumption

Opt for light tuna over albacore to reduce mercury exposure.
Choose fresh or frozen tuna when possible.
Limit canned tuna intake to 2-3 servings per week.
