Than that means Hidan isn't immortal cuz if he doesn't eat he dies. The only person in Naruto closest to never dying is Kaguya and Shinju because they're connected but we can't discredit others for having forms of immortality. And where did it say specifically that immortality in Naruto renders you from dying? A few characters said others were immortal but they could under certain circumstance. They wouldn't age or decay and if you didn't kill them by certain circumstance they'd live forever.
