Seafood is a broad term that describes the various forms of sea life that are eaten for food. It includes fish, molluscs, crustaceans, algae and other aquatic animals. Some groups of seafood are more common than others.

Crustaceans include oysters, clams, crabs, crayfish, octopus, mussels, and shrimp. These animals are generally eaten whole, but some are marinated. They are a rich source of protein, zinc, and vitamins B6 and B12.

Crustaceans are the main group of seafood. In addition to these, there are several other types. The variety of shellfish includes echinoderms, molluscs, and slugs.

Several studies have shown that people who consume a high amount of seafood are healthier than those who don’t. The nutrients in seafood may lower the risk of certain health conditions, such as cancer, CHD, and cognitive decline. Fish also contain omega-3 fatty acids. These omega-3 fatty acids are critical for the health of the nervous system and for healthy blood flow.

The United States Department of Agriculture (USDA) defines seafood as the edible part of aquatic animals. This is used in internal administrative purposes. However, there is no definition for seafood that specifically excludes mammals.

Seafood is highly perishable, so it is important to choose and store it carefully. Be sure to keep it in the refrigerator, and limit the time it is in the freezer. If you’re planning on freezing your seafood, remember that it needs to be stored at a temperature as low as -20 degrees F. A single pound package will defrost in about an hour. To maximize the quality of your frozen seafood, freeze it in its original packaging.

Many people don’t eat enough seafood. A three-ounce serving of seafood provides about thirty to forty percent of your daily protein requirement. Other essential nutrients in seafood are iron, selenium, and zinc. People with low levels of these nutrients may experience anemia and depression, so it’s important to increase your intake.

Almost every civilization in the world has integrated seafood into their diet. For instance, archaeological evidence indicates that Neanderthals and early Homo sapiens ate marine life. Similarly, the Tianyuan man, who lived in eastern Asia 40,000 years ago, regularly consumed freshwater fish.

Some common types of seafood are albacore tuna, bluefin tuna, Atlantic hard-shell clams, sturgeons, swordfish, tilapia, salmon, and trout. You can find these and other species in season year-round.
