Veganism is a philosophy and way of living that seeks to exclude, as far as possible and practicable, all forms of exploitation and cruelty to animals for food, clothing, or any other purpose. In dietary terms, it denotes the practice of dispensing with all products derived wholly or partly from animals. A vegan diet is based on plants, and vegans do not eat foods that come from animals, including dairy products and eggs. Additionally, vegans avoid using materials that originate from animals, such as wool and leather, and they don't use products that have been tested on animals
