Vegetarianism has steadily increased in Britain in recent years, rising by about 500 adults and children per year since 2010. A vegetarian diet avoids meat, fish and other animal products for various reasons like health concerns about fat and chemicals in meat, environmental concerns about resource use and habitat destruction, ethical concerns about animal welfare, and religious or personal beliefs. While only about 2% of Britain's population is vegetarian, many companies have expanded their meat-alternative offerings in response to growing interest in vegetarian options.
