The strict vegan diet and lifestyle excludes use of anything of animal origin, from food to leather clothing and other items such as glue or gelatin capsules; vegan is sometimes called eating lower on the food chain.
Vegan dietary practices and lifestyle are rooted in religious beliefs, respect for the environment, ethical and moral values concerning animal rights, and health practices thought to reduce the potential for disease. Vegans are cautioned, however, to obtain adequate nutrition. The PETA organization has popularized veganism in regards to prevention of cruelty to animals as does John Robbins’ Diet for a New America. There is also a concern that animal factory farming is a large contributor to the greenhouse effect, which is a key eco-motive towards vegan choices.
The growing popularity of veganism has produced a weath of fine recipes.
