I eat meat because I have a hatred for living things. Also plants are living things too, so I eat both. But I also prefer meat because I like the texture of it against, say corn. Also, the body can't process a lot of fruits and veggies. So in a way it could be bad for your colon.
To be honest, if it didn't directly kill me, I would eat anything if I liked the flavor and it could be edible.
