Non-vegetarian food contains meat, and sometimes, eggs. The term is common in India, but not usual elsewhere. In the generally vegetarian environment of India, restaurants offering meat and fish usually have a "non-vegetarian" section of their menu, and may include the term in their name-boards and advertising. When describing people, non-vegetarians eat meat and/or eggs, as opposed to vegetarians. But in India, consumption of dairy foods is usual for both groups.

Multiple symbols have been developed to represent lacto-vegetarianism and veganism. Several are used on food packaging, including voluntary labels such as The Vegan Society trademark or the V-Label as well as the vegetarian and non-vegetarian marks mandated by the Indian government. Symbols may also be used by members of the vegetarian and vegan communities to represent their identities, and in the course of animal rights activism.
