There are many different kinds of canned tuna you can buy nowadays, even beyond water-packed, oil-packed, and in a brine.

Of all the kinds of tuna you can make culinary creations with, ahi and albacore tuna may be some of the most popular but what makes them different?

Consumer Reports tested 10 products, including albacore and light tuna from each of the five tuna brands. In total, 30 samples — all tuna products that were packed in water — were tested.

For example, Chicken of the Sea’s albacore had 10 times more mercury than its light tuna, but mercury levels in Wild Planet’s albacore and skipjack tunas were very close to each other.

Ahi steak. Akami sashimi. Albacore on sourdough. Whether you smoked yellowfin on the grill or spread skipjack on a sandwich, chances are you’ve had tuna recently.
