Can a Vampire eat normal food?
No. A Vampire’s internal organs, including their stomaches are as dead as they are. Vampires don’t breathe, don’t excrete hormones, sweat, wastes or anything else — their skin does not contain sebum which means they seldom leave fingerprints behind though, of course, a bloody fingerprint would be possible. This means, since their stomaches do not secrete digestive acids, they cannot eat or digest food. While a vampire may be able to chew and swallow a hamburger, or drink a glass of wine, they will be compelled, very shortly, to vomit it back up. While such food is in their stomach they will feel extreme discomfort (which means fooling people into thinking they are human via this tactic is a touch-and-go thing at best). When a Vampire drinks blood, the vitae suffuses their entire body in way not fully understood but which is entirely unlike normal human digestion.
