Vegans cannot eat any animal/animal-derived foods. People choose veganism for many reasons. For some, health concerns may be the reason why they choose veganism while animal welfare or environmental concern may be the reason why some others choose veganism. People who follow the vegan way of life avoid all forms of animal products from their life.
 
Vegans do not eat meat, fish, poultry, eggs, milk, butter, cheese, gelatin, honey, and all other animal/animal-derived products. Meat, fish and poultry are obtained by killing the animals and such foods have no place in the vegan and vegetarian way of life. Milk, butter, cheese and honey are obtained through ways that cause harm to animals even if indirectly. Gelatin is obtained from the skin, ligaments and bones of dead animals including cow and pig. Vegans avoid desserts that have gelatin as their ingredient.
