A pescatarian diet is a plant-based diet that includes fish and seafood as the primary source of protein. Pescatarians eat fruits, vegetables, nuts, seeds, whole grains, beans, eggs, and dairy, and avoid meat and poultry. Some pescatarians may also consume other animal products such as eggs and dairy products. The term "pescatarian" is a combination of the Italian word for fish, "pesce," and the word "vegetarian". The pescatarian diet is considered a healthy diet as it is rich in nutrients such as omega-3 fatty acids, protein, vitamins, and minerals. Some pescatarians choose this diet for environmental reasons, as they believe that land animals raised for food use too many natural resources and add to pollution. The pescatarian diet has been shown to be more popular among women than men. Some drawbacks of the pescatarian diet include the risk of consuming too much mercury and other toxins found in certain types of fish.
