Seafood dishes refer to meals or courses that contain seafood as one of their main ingredients. Seafood includes a variety of marine animals such as fish, shellfish (e.g., crabs, lobsters, clams), and other aquatic creatures like squid and octopus. These dishes can range from simple preparations like grilled or fried fish to more complex ones like seafood stews, soups, or paellas. Seafood is a popular choice for many people due to its health benefits - it's high in protein, low in fat and calories, and contains essential vitamins and minerals such as iodine, iron, and zinc.
