The vegetarian diet includes or excludes different foods for different vegetarians, but there are three broad types of vegetarianism: Lacto-vegetarians include dairy products in their diet but do not consume meat, pork, or poultry. An ovo-vegetarian diet consists of eggs, not meat, pork, or poultry. A pescetarian is a vegetarian who eats fish as their main food but does not consume meat, poultry, or pork. Occasionally, vegetarians incorporate more than one of these foods into their diet. For example, some might identify themselves as lacto-ovo-vegetarians, who consume dairy products and eggs, or as ovo-pescatarians, who consume eggs and fish, but not dairy products.
