Albacore, the most expensive tuna. Canned tuna made from albacore is labeled 'white'. It has the mildest flavor and is easily substituted for canned chicken in most recipes.

Yellow fin tuna and other varieties are labeled 'light' on cans. It has a slightly stronger flavor than albacore. 'Light' tuna can contain several different varieties of tuna.

Bonita has the strongest flavor and highest fat content. This tuna is usually sold canned. If the can you're purchasing doesn't say 'white' or 'light, it's probably bonita or skipjack tuna.

Make sure that the tuna you purchase is labeled 'dolphin-safe'.
