The vegetarian diet is growing all over the world and in several countries. This is partly due to religious reasons but also to ethical reasons. Since vegetarians avoid eating the protein and essential nutrients found in these foods, it is more difficult for them to receive all the nutrients. Other researchers have reasoned that a consistent vegetarian diet may result in multiple health benefits from eating more vegetables, fruits, and legumes. There is a current belief among omnivores that vegetarians limit their diet only because they believe that animals should have the same rights as humans and although this is one of the reasons, it is not the main one.
