The Lacto-Ovo Vegetarian Diet
A lacto-ovo vegetarian (also known as ovo-lacto vegetarian, but sometimes incorrectly referred to as octo-lacto vegetarian, as "octo" means eight) is a vegetarian who does not consume dairy products (i.e. milk and its derivatives, like cheese, butter, or yogurt) and eggs. Lacto means "milk" and ovo means "egg".
In the Western world lacto-ovo vegetarians are the most common type of vegetarian. Generally speaking, when one uses the term vegetarian a lacto-ovo vegetarian is assumed. Lacto-ovo vegetarians are well-catered to in restaurants and shops, especially in Europe and metropolitan cities in North America.
Among lacto-ovo vegetarians who are motivated by ethical reasons, it is a common practice to avoid fertilized eggs as well as caviar because both involve the killing of sentient beings.
A lacto-ovo vegetarian doesn't eat poultry, meat or fish. However, cross-culturally, different cultures recognize vegetarianism differenly. For example, there is lacto-ovo, vegan, and even Japanese vegetarians who consider fish to be vegetarian.
