"The difference between a vegan and a vegetarian is that vegans eliminate all animal products from their diet, including dairy and eggs. Those following a vegan lifestyle generally do not wear leather and avoid products made from animals such as wool, silk and down. Vegans' tremendous compassion for animals is an abiding, overriding conviction in their lives.
Vegetarians do not eat meat, fish or poultry but they tend to consume dairy products and eggs. Lacto-vegetarians consume dairy products but not eggs, ovo-vegetarians eat eggs but not dairy products and lacto-ovo-vegetarians eat eggs as well as dairy products. Vegetarians also do not eat products that contain gelatine or other meat-based products.
The vegan point of view is that animals are not here to be exploited by man, and that commercialization of animals necessarily involves a fundamental, inhumane component and lack of respect for basic life.
From a nutrition point of view, the only difference is that vegans need to take a B12 and amino acid supplement, since they have no dietary source of these nutrients. You can get all the nutrients you need on a lacto-ovo (eggs and milk) vegetarian diet without supplements.
