how the hell do you know hidan eats? :Suhm...like i said, he's dead. his head was in a huge hole...he's not truly immortal, because he can die of malnutrition...he has no way of getting that nutrition...therefore, he's dead. weeeeeks have passed since that incident. so i'm positive he's dead
the dude's head can get severed and he can still talk, does that seem like anything humanly possible to you? so why do you think he requires human nutrients ? :S
