Vegetarian

Vegetarianism encompasses the practice of following plant-based diets (fruits, vegetables, etc.), with or without the inclusion of dairy products or eggs, and with the exclusion of meat (red meat, poultry, or seafood). Abstention from by-products of animal slaughter, such as animal-derived rennet and gelatin, may also be practiced.

Semi-vegetarian diets consist largely of vegetarian foods, but may include fish or poultry, or other meats on an infrequent basis. Those with diets containing fish or poultry may define "meat" only as mammalian flesh and may identify with vegetarianism. A pescetarian diet, for example, includes "fish but no meat". The common use association between such diets and vegetarianism has led vegetarian groups such as the Vegetarian Society to state diets containing these ingredients are not vegetarian, due to fish and birds being animals.
