Healthline explains that the term pescatarian, sometimes spelled pescetarian, was coined in the 1990s as a way to combine the words pesce (which means fish in Italian) and vegetarian. It is a lifestyle that is considered to be along the vegetarian spectrum, and refers to people who actively choose to cut out meats and poultry and focus on eating fish, seafood, and veggies. Heathline adds that many people who identify with this eating style often eat dairy and eggs, too.
Consuming a pescatarian diet leads to better overall nutrition as they are eating more fiber and heart-healthy polyunsaturated fats (via Eating Well). Studies have shown that pescatarians are said to get more calcium in their diets than vegans, vegetarians, and omnivores. Another benefit is that pescatarians are said to be at a lower risk for chronic conditions like type 2 diabetes and high blood pressure, according to Eating Well. The one possible drawback about consuming a fish-heavy diet is that fish carry mercury — a toxin that accumulates in fish, shellfish, and other seafood. Although many experts feel that the benefits of regular fish consumption outweigh the potential risk of mercury exposure, it’s a good practice to know which fish carry the most mercury.
