Many Types of Vegetarians
There are many kinds of vegetarians. Here are some of them:
lacto-ovo vegetarian: eats no meat, but will eat dairy products (milk, butter, cheese) and eggs
ovo-vegetarian: eats eggs, but no meat or dairy products
vegan (say: VEE-gun): eats no meat or animal products
And many other people are semi-vegetarians who don't eat meat, but may eat poultry or fish.
