Fish is one of the most important sources of animal protein in the world. It is high in protein, low in fat, and low in calories. Seafood is also a very good source of healthy omega-3 fatty acids. Research has shown that diets containing a lot of seafood have been linked to better cardiovascular health and a lower risk of various diseases. A diet rich in seafood may even be protective against cognitive decline and coronary heart disease.

Seafood includes all bony fishes and shellfish. Some examples include lobsters, abalone, sea urchins, scallops, oysters, sturgeons, and sea turtles. Depending on the species, seafood can be consumed uncooked or cooked. The latter is often done in many savoury dishes. However, the former is generally more delicate and is prepared with milder seasonings.

There are two main types of seafood: freshwater and saltwater. Freshwater species live in lakes, rivers, and oceans. Saltwater species are usually found in the oceans and are often very high in omega-3 fatty acids. They are great sources of vitamins and minerals.

Both freshwater and saltwater species have a wide range of culinary uses, including fish, shrimp, crabs, clams, and mussels. These foods can be eaten raw, steamed, poached, or fried. Many people enjoy eating seafood, but overfishing has devastated the marine ecosystem worldwide. Therefore, it is essential to be sure to purchase sustainably caught seafood.

Seafood is an important source of protein and contains other vital nutrients. A 3-ounce cooked portion of fish offers about 30 percent of the daily protein requirements, and a diet containing seafood is a good choice for those who want to lose weight.

Most lean seafood has about 100 calories per three-ounce serving. However, fattier fish can contain up to 200 calories. This makes seafood a healthier option than meat, which has between 10 and 20 calories per protein gram. Because of its lower calorie content, seafood is often recommended to people who are trying to lose weight.

Seafood is also a great source of vitamins and minerals. Various cultures around the world consume a variety of seafood. For example, the Tianyuan man in eastern Asia is known to have regularly consumed freshwater fish. Other ancient civilizations ate seafood. Archaeological evidence suggests that humans have been collecting and consuming marine life for at least 165,000 years.

Besides providing high-quality protein, seafood is an excellent source of vitamins, antioxidants, and fatty acids. Eating seafood is a healthy and environmentally responsible way to supplement your diet. Be sure to look for seals of certification on seafood products, like the Monterey Bay Aquarium’s Seafood Watch.

Seafood is an ideal protein source for those following a low-calorie or low-fat diet. However, be sure to limit fried or processed seafood. Instead, cook and prepare your meals with other nutritious foods. If you’re interested in learning more about seafood, use the USDA’s online seafood nutrition guide to find out more.

Seafood is a nutritious, high-protein food, and it can be easy to prepare. However, overfishing has destroyed marine environments around the globe, and reducing the number of species can have catastrophic consequences.
