vegan

If you’re a vegan, you’re a strict vegetarian, and you don’t eat anything that comes from an animal — not even eggs or dairy. Most vegans also avoid using animal products like wool and leather.

A vegan diet is heavy on fruits, vegetables, nuts, and grains, and since only animal products contain cholesterol, vegans are often healthier than the steak-and-potatoes crowd. On the other hand, eating out can sometimes be harder for a vegan, since things like pizza with mozzarella and hamburgers aren't options. As you no doubt noticed, vegan is related to vegetarian and vegetable.
