Lacto-ovo vegetarianism or ovo-lacto vegetarianism is a type of vegetarianism which forbids animal flesh but allows the consumption of animal products such as dairy and eggs. Unlike pescetarianism, it does not include fish or other seafood. A typical ovo-lacto vegetarian diet may include fruits, vegetables, grains, legumes, meat substitutes, nuts, seeds, soy, cheese, milk, yogurt and eggs. In India, such vegetarians are known as "eggetarian," which is a portmanteau of egg and vegetarian as "vegetarianism" usually refers to lacto vegetarianism in India. The terminology stems from the Latin lac meaning "milk" (as in 'lactation'), ovum meaning "egg", and the English term vegetarian, so as giving the definition of a vegetarian diet containing milk and eggs. In the Western world, ovo-lacto vegetarians are the most common and most traditional type of vegetarian. Generally speaking, when one uses the term vegetarian, an ovo-lacto vegetarian is assumed. Ovo-lacto vegetarians are often well-catered for in restaurants and shops, especially in some parts of Europe and metropolitan cities in North America. In Indian religions like Hinduism and Buddhism, most individuals are either raised as ovo-lacto vegetarians or lacto vegetarians. However, consumption of egg is not considered a part of vegetarian diet in India, as egg is an animal-product that gives birth to the next generation of that species. Those who consume egg, while not consuming other non-vegetarian products (such as fish and meat), refer to themselves as 'eggitarians'. The Bible Christian Church was a Christian vegetarian sect founded by William Cowherd in 1809. Cowherd was one of the philosophical forerunners of the Vegetarian Society founded in 1847. The Bible Christian Church promoted the use of eggs, dairy and honey as God's given food per "the promised land flowing with milk and honey" (Exodus 3:8). Many Seventh-day Adventist followers are ovo-lacto vegetarians and have recommended a vegetarian diet, which may include milk products and eggs, since late 19th century.
