Although tuna is very nutritious, it's also high in mercury compared to most other fish. Therefore, it should be eaten in moderation – not every day.

Limit albacore and regular light tuna (canned) to no more than 12 oz. per week. A better alternative is canned salmon, mainly sockeye or pink from Alaska (these are low in contaminants and high in heart-healthy Omega-3s).
