How are a vegan and a lacto-ovo vegetarian similar and different?

Answer 1

Similarities

Both vegans and lacto-ovo vegetarians abstain from consuming foods or ingredients that require the death of an animal: meat, fish, the flesh of other formerly living things, gelatine, rennet, pig-derived insulin, etc.

Individuals who are vegan or vegetarian for ethical reasons will also abstain from using non-food products that require an animal's death, for example, leather and silk.

DifferencesTrue vegans don't consume or use any animal-derived products whether an animal had to die or not. For example, they won't consume dairy, eggs, or honey, and they won't use cosmetics that contain bee pollen.

Lacto-ovo (or ovo-lacto) vegetarians will consume eggs and dairy, except for cheeses and whey that were made with animal-derived rennet. They will often also consume or use other animal-derived foods and products that were made without causing an animal's death.

Answer 2

A Lacto-Vegetarian eats dairy products, an Ovo-Lacto-Vegetarian eats eggs and dairy products.

Answer 3

A lacto vegetarian eats dairy products (milk, cheese), and an ovo vegetarian eats eggs. Neither kind eats meat or poultry, and they generally eschew fish as well.

Answer 4

An ovo-vegetarian eats eggs, an ovo-lacto vegetarian eats eggs and dairy products.
