A vegan follows the philosophy of the diet.
I always thought about being vegan but was never sure what it entailed?  Are you vegan?
No, but it's the practice of abstaining from the use of animal products.
Does that include things like milk and eggs?
Dietary vegans refrain from eggs, dairy products, and other animal products.
What can they eat instead?
Well executed vegan diets reduce the risk of some chronic diseases.
