Seafood includes a large group of marine animals that live in the sea, fresh water, lakes, and rivers. Fish such as salmon, tuna, trout, and tilapia, along with shellfish such as shrimp, crab, and oysters, are included in this group.
Seafood is an important part of a balanced diet because it contains high-quality protein, good fats called omega-3 fatty acids, and other nutrients. However, many of us do not include enough seafood in our diets to get the full range of benefits.
