A pescatarian is someone who follows a diet that includes fish and seafood but excludes other types of meat, such as beef, pork, and poultry. This dietary choice often emphasizes the consumption of vegetables, fruits, grains, and legumes, making it a popular option for those looking to eat healthier while still enjoying the benefits of protein from fish. Many people choose a pescatarian diet for various reasons, including health benefits, environmental concerns, or ethical considerations regarding animal welfare. By incorporating fish like salmon and tuna, pescatarians can enjoy essential nutrients like omega-3 fatty acids, which are beneficial for heart health.
