There are different types of vegetarians defined by what they do and do not eat. Lacto-ovo vegetarians eat eggs and dairy but not meat, while vegans eat no animal products. People become vegetarian for health reasons like lowering cholesterol, moral objections to animal killing, or religious restrictions. A 2012 UK survey found over 3000 vegetarians, most of whom were female and chose vegetarianism for ethical reasons. Major vegetarian food companies produce meat alternatives and ready meals without meat to meet vegetarian dietary needs.
