I wonder what the breakdown between meat/poultry and fish was. I know it isn't the dictionary definition, but I think the common definition of "vegetarian" in the US includes people who only eat fish. I don't know anyone that uses "pescatarian" in conversation or identifies as that, even if it's accurate.
Vegetarian = no meat, no chicken, no fish, no crustaceans, no dead animals, no meat/fish broth, no lard. Nothing derived from a dead animal. Or as my little sister used to ask: “did this have a face?”
But that’s what “vegetarian” means to me. I guess that’s a “strict vegetarian”?
Time didn't break down their results between meat/poultry and fish, but they did break them down between "red meat" and poultry/fish; 37% of vegetarians had eaten red meat within the last day.
Like humanity in general, there is a lot of variety. My dad has been a pescetarian for 30+ years, so I'm aware of the term and use it at least two or three times a year. Personally, I'm a flexitarian and eat a reduced animal flesh diet. I know quite a few vegetarians, and they don't all eat the same diet (one does eat eggs on a weekly basis and still calls himself a vegetarian, which is somewhat controversial according to the other vegetarians that I talk to). Most vegetarians I know don't consume fish or dairy.
