The reasons why some people decide not to consume meat are different, which to some extent explains the different categories of vegetarianism.
Some stop eating meat as a protest against the factories that produce it, while others because they don't want animals to be killed in order for them to be fed.
And while the experts continue their debates over the benefits and harms of vegetarianism, a significant amount of people choose one of the 5 groups of food diet which to follow.
This is one of the newer types of vegetarians, describing people who lead a semi-vegetarian way of life. Flexitarians mainly eat foods of plant origin, including dairy products, eggs and meat and fish only from time to time in their diet.
According to flexitarianism, the meat which they consume needs to be obtained by ethical means only, i.e. the animals need to have lived freely and to have fed on organic foods.
Some flexitarians eat meat dishes only if they are served to them at social events, but never cook meat in their own home.
Pescetarians are also among one of the new groups. The name owes its origin to the Italian word "pesce", which means fish.
Seafood is a key source of proteins, healthy fats and some minerals.
This is the most popular type of vegetarianism and includes the most amount of people. Lacto-ovo vegetarians do not consume any type of meat but do eat products of animal origin, such as milk, cheese and eggs.
This group also includes lacto-ovo vegetarians who eat eggs but not dairy products.
The food diet of vegans is based solely on plant foods, with the people from this group abstaining from consuming meat and animal products.
Raw foodists refrain from eating any products of animal origin. The people in this group only eat foods that are prepared at a certain temperature, because it is thought that heat treatment produces cancerous substances.See more
