A pescatarian is someone who follows a diet that includes fish and other seafood but excludes other types of meat, such as beef, pork, and poultry. This dietary choice often stems from health, environmental, or ethical considerations. Pescatarians typically consume a variety of plant-based foods, including fruits, vegetables, grains, and legumes, alongside their seafood. Many pescatarians choose this lifestyle for its perceived health benefits, as fish is a good source of omega-3 fatty acids and protein. Additionally, some people find that a pescatarian diet is more sustainable than a meat-heavy diet, as it can have a lower environmental impact.
