Can anyone tell me why it is forbidden for Vampires in the Twilight world to eat regular food along with a staple of animal's blood?
Every vampire tome portrays vampires as the Undead. As in their insides don't work anymore. So it's not so much that they're forbidden - it's just they can't do anything with it internally. So since they're never going to shit it out they have to either not eat it or throw it back up.
The question is...since Edward is undead and his insides don't work....how will he get Bella knocked up? Eddie should be shooting blanks.
...and the like*or some sort of infection like in Ultraviolet?
I think it was in the theater version that the hemophages in
Ultraviolet were nicknamed "Vampires" by the press because the disease somehow made the victim's canine teeth grow and made them sensitive to light (although it varied among victims so Violet could walk around like normal but Garth had to wear the shades and stay out of the sun). But they didn't drink blood.
