What makes tuna so powerful?

Canned light tuna in water is the lowest-calorie way to eat it, while tuna packed in oil adds calories from the oil. Mercury varies by type: US FDA guidance lists canned light tuna among the lower-mercury choices and albacore as a more limited one. Draining the can lowers calories if it was packed in oil.
