Lacto-ovo vegetarianism or ovo-lacto vegetarianism is a type of vegetarianism which allows for the consumption of animal products that do not involve slaughter, such as eggs and dairy. Unlike pescetarianism, it does not include fish or other seafood. A typical ovo-lacto vegetarian diet may include fruits, vegetables, grains, nuts, seeds, herbs, roots, fungi, milk, cheese, yogurt, kefir, and eggs.[1]


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 type of vegetarian.[2][unreliable source?] Generally speaking, when one uses the term vegetarian, an ovo-lacto vegetarian is assumed.[3] Ovo-lacto vegetarians are often well-catered to 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.[4]

The Bible Christian Church was a Christian vegetarian sect founded by William Cowherd in 1809.[5] 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).[6]

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.[7]
