Yes, they do.
ヴァンパイア must eat"normal human" food, too. It is important to keep a healthy diet; they must abide によって the 食 pyramid just as much as any body else on the planet. Because they're not dead nor undead, but are living, their bodies still function fine, including the digestive system. Blood is merely something else that they must ingest toremain healthy in addition to what is on the 食 Pyramid. If any creature were to go without nourishment (blood has various nutrients in it, but cannot sustain a livingbeing -- it is physically impossible --) they would die, it is as simple as that.Once their body dies, thatbody cannot come back to life, it is as simple as that.Mythology threw all of it way out of proportion.
