Pescatarians are similar to vegetarians. The difference between pescatarians and vegetarians is that pescatarians eat fish and shellfish in addition to an otherwise vegetarian diet. Major vegetarian organizations, including The Vegetarian Society, does not recognize pescatarians as true vegetarians. Pescatarians believe that they can improve their health. Being pescatarian doesn't automatically make you healthier, in the same way that being a vegetarian doesn't equal instant health. There are a wide variety of snack and junk foods that do not contain animal products, such as potato chips, snack cakes, cookies and even ice creams. Pescatarians still have to be careful of their saturated fat intake even though they do not eat land animals or birds. According to Pescatarian Life, pescatarians may or may not eat dairy, like other types of vegetarians. This is a personal choice that each pescatarian makes based on his own values and opinions about the dairy system. It's not safe to assume that pescatarians eat dairy when preparing meals. It's always best to ask.
person 1: Do you eat meat?
Person 2: Not land animals or birds, but sea food.
Person 1: So you're a vegetarian who eats fish.
Person 2: NO! I am a pescatarian!
Person 1: Why don't you eat land animals or birds?
Person 2: I don't eat land animals or birds because of the hormones and steroids they are injected with, and because 90% of mass produced land and bird meat in the US are gmo and contain human dna.
