What is a vegetarian?

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

The reasons for being a vegetarian are diverse:

  • For health : some people stop consuming meats more for a health need than for a choice. A notable example is that of Albert Einstein, who suffered from intestinal problems that were aggravated by the consumption of meat.
  • By religion : Buddhists, Hindus, and Adventists are vegetarians by religious belief.
  • By culture : some ancestral and indigenous cultures base their diet only on plants.
  • For ethics : Some people consider that eating animals is a reprehensible act.
  • For the environment : the massive 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, with a very low percentage in the rest of the countries.
