A vegan is a person who follows a strict vegetarian lifestyle and shuns the use of animals not only for food but also for clothing, medicine, etc. Vegans are vegetarians in the purest sense. Vegans eschew animal products on the grounds of an ethical concern for animal rights, the environment, human health, and religion. Vegans are strong opponents of factory farming and animal testing. Close to 1.5% of the American population professes to veganism.
