The Difference Between Vegetarian, Vegan, and Other Diets

The word vegetarian sprouted up in 1839. Fruitarian ("a person who lives on fruit") ripened by 1893. In 1944, vegetarians who consume no animal or dairy products began calling themselves vegans. Then, in 1993, those who eat fish but no other meat chose pesce, the Italian word for "fish," to create the designation pescatarian. In that same year, meatatarian was served up as a word for those whose diet largely includes meat; that word is rare, however, and is usually used in informal and humorous ways, making it the type of fare not included in our dictionaries. Another fairly recent dietary word is flexitarian, a person who follows a mostly vegetarian diet but occasionally eats meat or fish.
