Ovo-lacto vegetarianism is a dietary lifestyle that involves abstaining from meat, fish, and poultry but includes the consumption of eggs and dairy products. There are several other terms commonly used to refer to this type of vegetarianism. Some of the most popular synonyms include lacto-ovo vegetarianism, dairy-vegetarianism, and egg-vegetarianism. These terms differ in the order in which they mention the inclusion of dairy products and eggs. Lacto-ovo vegetarianism is often used interchangeably with ovo-lacto vegetarianism and refers to the same dietary practice. Egg-vegetarianism and dairy-vegetarianism, on the other hand, emphasize the specific products that are consumed while omitting meat, fish, and poultry from the diet.
