Vegetarians are individuals that involves in a dietary practice whereby they avoid some foods such as meat and by products of meat. This is practised by these individuals either due to the health benefits or for some religious beliefs.
There are different types of vegetarians, these include:
--> strict vegetarians
--> lacto vegetarians
--> Ovo vegetarians
--> Pesco vegetarians
--> partial vegetarians and
--> lacto Ovo vegetarians.
LACTO OVO VEGETARIANS are those vegetarians that exclude meat, poultry, and fish but take plant-based foods, dairy products, and eggs. They can obtain vitamin B-12 from hard boiled eggs and yogurts. This is so because, Vitamin B12 is naturally found only in animal foods such as meat, fish, seafood, poultry, eggs, milk, yogurt and cheese. Since the lacto ovo vegetarians do not feed on meat, fish or seafood, the potential sources of vitamin B-12 for a person who follows a lactoovovegetarian dietary pattern are hard boiled egg and dairy products such as yogurt
