Normally when a person says that is usually associated with vegetarian eating habits to the absence of feeding animal meat. However, as we all know, this perception is wrong because the majority of people are vegetarian veganism, and tolerate in your diet products of animal origin such as eggs and dairy, as its name.
Specifically, if we talk about vegetarianism in the strict sense we should refer to veganism, a practice that is a total abstention from eating foods that have any kind of animal origin.
The vegan has permeated the whole philosophy of life that implies respect for nature and animal rights, in addition to defending human rights, and, although it derogatory, in my opinion, no longer a postmodern practice unnecessary without any strength.
