However, under the label vegetarian one can also fit into other categories depending on how extensively the diet is limited. The ovolacto-vegetarian is the most commonly followed vegetarian diet. Ovolacto-vegetarians will eat both dairy and egg products, but do not eat foods that contain animal products. Ovo-vegetarians, however, will consume eggs. Ovo-vegetarians are uncommon.
Vegans avoid eating any food item which contains any form of animal by-product.
Veganism in general is becoming much more common, and many vegetarians evolve to embrace veganism. An extension of veganism called fruitarianism has recently emerged. This diet is the same as that of a vegan, however frutarians consume a smaller amount of processed and cooked foods. A fruitarian s diet mainly consists of raw fruit, grains, and nuts. The Vegetarian Society maintains that being a vegetarian is not extremely difficult.
