What is a vegetarian?

Vegetarians do not eat meat, fish or poultry; in general, they do not eat dead animals. Vegetarianism is the diet or nutrition based mainly on the consumption of foods of vegetable origin. Some vegetarians consume products obtained from live animals, such as milk and its derivatives and eggs.

There are several reasons to be a vegetarian:

  • for health: some people stop eating meat more out of a health need than a choice. A notable example is Albert Einstein, who suffered from intestinal problems that were aggravated by eating meat.
  • By religion: Buddhists, Hindus and Adventists are vegetarians by religious belief.
  • By culture: some ancestral and indigenous cultures base their diet solely on plants.
  • For ethics: Some people consider eating animals to be a reprehensible act.
  • For the environment: the mass production of animals for human consumption represents a huge ecological footprint; if animals are not consumed indirectly, it is believed that the agricultural industry is being affected.

The Greek mathematician Pythagoras (569-475 BC) is considered the father of ethical vegetarianism. There are now numerous scientific and epidemiological studies showing the health benefits of vegetarian diets.

The only country where a third of the population is vegetarian is India, and in the rest of the countries it is a very low percentage.
