Vegetarianism is a kind of food culture. People who practice this diet culture are called vegetarians. These people don't eat food made from various parts of animals, including animal oil and animal glue. Vegetarianism varies from country to country or from culture to culture. Some vegetarians can eat honey, milk and eggs, while others cannot. Vegetarianism shows the cultural concept of returning to nature, health and protecting the ecological environment of the earth. Being a vegetarian can not only get natural and pure balanced nutrition, but also experience the pleasure of getting rid of the noise and desire of the city. The quietly spread vegetarian culture has made vegetarian food more and more a global fashion label. Vegetarianism has become a brand-new environmental protection and healthy lifestyle.
