Like the Sun, Moon, and Earth, there are three kinds of vegetarians in existence: ovo-lacto, a vegetarian that eats vegetables, fruits, grains, legumes, seeds and nuts, as well as eggs and dairy products. Lacto, a vegetarian that eats everything the "ovo-lacto" does, except eggs. Finally, we have vegans, a vegetarian that eats what the rest of the others eat, except for any kind of animal products, period. Each group of vegetarian is unique, but branches from the same tree of life.Why would anyo.
