Seafood (marine or saltwater fish) refers to any animal living in oceans, seas or brackish water (a combination of salty and freshwater). This category encompasses numerous crustaceans (shrimp and crab), shellfish species such as prawns, lobsters, mussels and scallops as well as edible sea plants such as kelp that provide essential vitamins and nutrients.

Fish are among the most widely consumed types of seafood and provide essential protein, vitamin B6, zinc, selenium and omega-3 fatty acid benefits. Wild-caught or farmed, they make a versatile ingredient which can be poached, sauteed, fried grilled baked deep-fried

Oily fish is an excellent source of omega-3 fatty acids and helps support heart and brain health. In addition, oily fish also contains high concentrations of vitamin D, calcium, phosphorus, and magnesium – tuna, salmon, mackerel are among some examples.

White fish is a nutritious option that many individuals turn to when seeking to reduce their meat consumption, with no increased saturated fat intake and plenty of B6-niacin, choline, and magnesium-rich species such as cod, haddock, plaice, pollock whiting gurnard dab flounder.

Shellfish are an abundant source of protein and minerals like zinc, selenium and iodine. Bivalves feature hinged shells which open and close for maneuverability in water while gastropods like snails (escargot) or periwinkles have single shells.

Mollusks are another category of seafood that includes creatures such as squid and octopus, providing an excellent source of protein, zinc, selenium, and iron. Squid and octopus boast soft bodies with no hard shell but long arms for swift movement through water environments.

Sustainable seafood choices are an easy way to ensure there will be enough fish for future generations. By supporting local fishing industries and purchasing only responsibly caught or raised fish, you can help reduce overfishing which harms the environment while making eating seafood harder in future years.
