A pescatarian is someone who eats fish and seafood but doesn’t eat other types of meat, like chicken, beef, or pork. It’s like being a vegetarian but with fish. Fish are animals that live in water, and some people choose to eat them for food. Pescatarians believe that eating fish is a healthy choice for their bodies. By choosing to be a pescatarian, they can still eat a variety of tasty foods while avoiding other kinds of meat.
