About Can tuna

Canned tuna is a convenient food made by cooking and preserving tuna fish in cans, often with water, oil, or brine. Originating in the early 20th century as a resource-saving preservation method, canned tuna is popular worldwide and prominently features in Mediterranean, Asian, and Western cuisines.
