What is the difference between a vegetarian and a vegan?
user
A vegetarian would eat fruits and vegetables, grains, and legumes, while avoiding meat, fish, and poultry, or dairy products, and they might make exceptions for medical reasons, such as pregnancy or lactation.  A vegan would eat a similar diet, but with no animal products whatsoever, or even all products that were made using animal-based ingredients, such as gelatin, honey, and silk.

Ah, great question!  A vegetarian is someone who does not eat animal flesh, for instance including no beef, pork, lamb, seafood, or poultry.  A vegan also does not eat these things, but additionally also does not use any animal products, for instance in products like clothing, makeup, and furniture.
