Tuna Fish

Tuna is a saltwater fish found in oceans worldwide. It is a popular source of protein, often canned or sold as fresh fillets. Canned tuna is typically cooked, and the flesh is then packed in water, oil, or brine.

Tuna is primarily used as a protein source in foods like salads, sandwiches, and casseroles. Its distinct flavor also makes it a key ingredient in dishes such as tuna salad and tuna melts. Manufacturers use it for its nutritional value and savory taste.

Tuna is a good source of protein and omega-3 fatty acids. However, some types of tuna can contain higher levels of mercury, a heavy metal. The FDA advises certain groups, like pregnant women and young children, to limit their intake of fish with higher mercury levels. JECFA has evaluated tuna and found no safety concerns at typical consumption levels.
