The difference between a vegan and a vegetarian is that a vegan eliminates all animal products from his or her diet, including dairy. Those following a vegan lifestyle generally do not wear leather and avoid products made from animals such as wool, silk and down. Vegans’ tremendous humanity for animals is an abiding, overriding conviction in their lives.
Vegetarians do not eat meat, fish or poultry, but might eat dairy products such as cheese, eggs,yogurt or milk. Vegetarians are not as predictable in their beliefs, as there are many reasons to become vegetarian that don’t necessarily include altruism as a primary motive. For example, many vegetarians have eliminated meat for the sake of their health. In fact, there are a great many people lumped into the category of vegetarian. Lacto-vegetarians will eat dairy, but not eggs. Ovo-vegetarians will eat eggs, but not dairy. Lacto-ovo vegetarians will eat eggs and dairy products. The reasons for these choices are varied and based on individual beliefs. In some cases they are based on moral choices, and in others on dietary needs or simple preference.
