you are right...
no one says the u must be a veggi...

any one can each both veg and non veg....

but i prefer vegg.. more than non veg.

the reason is....
fruits and veg provide more energy than non veg.

the digestion is simple and no load to stomach.

apart from this there are many reason to be a veg.
if u want spiritual growth, u must be veg.

and by veg... it does not mean u can eat any fruits and any vegetables..

there are a list of things which can be used.

so u see....
you diet depend on ur body needs and what u want to do with ur body..

people can live without food...
only by drinking water....
