The Different Forms of Vegetarian
Vegetarianism is a practice where one refrains from consuming meat, fish and/or any animal-product. Although this seems pretty straight forward, there are three different levels of vegetarianism:
Lacto-ovo-vegetarianism
According the Vegetarian Society of the United Kingdom, this is the most common type of vegetarianism. It consists of a diet highly plant-based (i.e. nuts, seeds, grains, fruits and vegetables), excluding fish, meat, and poultry but allowing for the consumption of both egg and dairy.
Lacto-vegetarianism
This diet is nearly identical to that of lacto-ovo-vegetarians but instead of including both dairy and eggs, they exclude the consumption of eggs and anything made with eggs.
Vegan
Vegan is the strictest form of vegetarianism. This way of life excludes the consumption of all animal-products including any product that is produced with an ingredient that derives from animals.
Note: Pescatarians are commonly mistaken as vegetarians however they are not. Although this practice excludes the consumption of poultry and meat, in includes fish and various sea foods in the diet.
