What kind of Vegetarian would you like to-be? Pross and Cons

A vegetarian diet can make it easier to get the recommended minimum of five daily servings of fruits and vegetables, but a purely vegetarian diet is not necessarily better than a plant-based diet that also includes fish or poultry. People who follow a vegetarian and especially a vegan diet may be at risk of getting insufficient vitamin D and vitamin K, both needed  for bone health. Although green leafy vegetables contain some vitamin K, vegans may also need to rely on fortified foods, including some types of soy milk, rice milk, organic juices and breakfast cereals. Well as you see is not easy to be the kind of vegetarian you want.

Becoming a vegetarian requires planning
and knowledge of plant-based nutrition.Strictly speaking, vegetarians are people who don’t eat meat,
poultry, or seafood. But people with many different dietary
patterns call themselves vegetarians, including the following:
Vegans (total vegetarians): Do not eat meat, poultry, fish,
or any products derived from animals, including eggs, dairy
products, and gelatin.
Lacto-ovo vegetarians: Do not eat meat, poultry, or fish, but
do eat eggs and dairy products.
Lacto vegetarians: Eat no meat, poultry, fish, or eggs, but do
consume dairy products.
Ovo vegetarians: Eat no meat, poultry, fish, or dairy products,
but do eat eggs.
Partial vegetarians: Avoid meat but may eat fish (pescovegetarian,
pescatarian) or poultry (pollo-vegetarian).
