My name is Christine Marquette, and I'm a registered dietitian with the Austin Regional
Clinic. And I'm going to talk to you about the four types of vegetarians. Now what's
most commonly recognized is the four types of vegetarians, first would be lacto ovo vegetarians.
Lacto referring to dairy, ovo referring to eggs. So this means this is a person who doesn't
eat any meat, they don't eat any seafood, but they will still include dairy products
and eggs in their diet. Dairy products meaning things like milk, cheese, yogurt. The second
type of vegetarian is a lacto vegetarian. So this particular type of vegetarian will
use dairy products, but they don't use eggs, and they don't use any other animal products.
So no meat, no seafood, no poultry. The third type of vegetarian would be an ovo vegetarian.
So this type of vegetarian will have eggs, but they won't do any other dairy products.
No milk, no cheese, no yogurt, and of course they don't eat any meat, poultry, seafood.
And then the last type of vegetarian is a vegan. A vegan is a person who doesn't use
any animal products at all. So no dairy, no eggs, no meat, no poultry, no seafood. They're
strictly using plant foods for their diet. This also means that they are not taking any
supplements or anything that comes from an animal. So they're not going to be taking
fish oil supplements if they want a source of omega three, they will use a marine source
like marine algae to get their omega three. Or they may use flax seed, but they're not
going to use a fish oil as their method of getting omega three, because again they avoid
all sources of animal foods. Some times you will hear somebody mention something like
the semi-vegetarian or flexatarian, this isn't truly a vegetarian. People who truly call
themselves semi-vegetarian, they'll still eat meat on occasion or some type of animal
product. They just are cutting back on the amount of meat that they are actually eating.
So that's not actually truly a type of vegetarian. There really are only the other four that
we talked about, ovo, lacto, lacto ovo, or vegan.
