How does the mercury level in canned light tuna compare to albacore tuna?
Answer
Canned light tuna generally contains less mercury.
When consuming canned tuna, it is important to distinguish between the varieties available because their mercury profiles differ significantly. Canned light tuna is characterized as containing less mercury compared to albacore tuna. Consequently, dietary guidelines permit consuming more of the light variety throughout the week than the albacore variety. Specifically, albacore tuna should be limited to no more than 4 ounces weekly, reflecting its elevated mercury concentration relative to the light canned option.
