It provides high-quality protein, healthy fats, vitamins, and minerals that support your heart, brain, muscles, and overall well-being. Whether you enjoy fish, shrimp, crab, or shellfish, seafood offers a variety of nutrients that are difficult to obtain from many other foods.
Health experts around the world recommend eating seafood regularly as part of a balanced diet. However, choosing the right types and preparing them in healthy ways can make a big difference.
In this guide, you’ll learn what seafood is, its nutritional benefits, the healthiest options, potential risks, and practical tips for adding more seafood to your meals.
What Is Seafood?
Seafood refers to edible aquatic animals that come from oceans, seas, rivers, and lakes. It generally falls into two main categories:
- Fish, such as salmon, tuna, sardines, cod, trout, and mackerel.
- Shellfish, including shrimp, crab, lobster, oysters, mussels, scallops, and clams.
Seafood is valued for being rich in protein while often being lower in saturated fat than many red meats.
Nutritional Value of Seafood
Although nutritional values vary by species, most seafood provides an excellent balance of important nutrients.
Common nutrients found in seafood include:
- High-quality protein
- Omega-3 fatty acids

Many fatty fish are among the best natural sources of omega-3 fatty acids, which play an important role in maintaining heart and brain health.
Health Benefits of Seafood
1. Supports Heart Health
Many types of seafood contain omega-3 fatty acids that may help support normal heart function as part of an overall healthy lifestyle. Regular seafood consumption is also associated with a balanced diet that supports healthy cholesterol levels and normal blood circulation.

When paired with calcium-rich foods, seafood becomes an excellent part of a bone-friendly diet.
