The group included both vegans and lacto-ovo-vegetarians
avoid all meat, fish and meat by-products, such as gelatine and animal fats.
There are also pesco-vegetarians, who supplement their diet with dairy products, eggs and fish; lacto-ovo-vegetarians
, who eat eggs and dairy products, but no fish; and lacto-vegetarians, who consume dairy products, but no eggs or fish.
* Those who avoid meat, but eat both dairy products and eggs: lacto-ovo-vegetarians
Lacto-ovo-vegetarians: those who eat dairy products and eggs, but no animal flesh.
In fact, some research has shown that lacto-ovo-vegetarians, in particular, may have a lower risk of osteoporosis (the gradual loss of bone mass, due to inadequate calcium stores) than people who eat lots of animal protein.
In 1983 some members became lacto-ovo-vegetarians
(diets including milk and dairy products).
* Vegans and lacto-ovo-vegetarians consumed negligible amounts of meat
Self-reported results showed 7.7 percent were vegan (exclude all animal products), 29.2 percent lacto-ovo-vegetarian (include dairy products and eggs), 9.9 percent pesco-vegetarian (include seafood), 5.4 percent semi-vegetarian (eat animal products/seafood one or fewer times per week), and 47.7 percent non-vegetarian (eat animal products/seafood more than once per week).
These include semi-vegetarian (flexitarian), pesco-vegetarian, lacto-vegetarian, ovo-vegetarian, lacto-ovo-vegetarian
, vegan, and raw food vegan diets.
For example, a lacto-ovo-vegetarian
diet might be expected to provide more protein, calcium and phosphorous than a vegan diet.
