Can 吸血鬼 eat 食物 as well? 或者 do they get sick?

They can 吞, 燕子 the 食物 but they won't digest it. Like in the first book when Edward ate a bite of Bella's 比萨, 比萨饼 he had to cough it back up later. They all think 食物 it pretty gross too. (Like us eating dirt.)

well, edward did eat a slice of cold 比萨, 比萨饼 with charlie in eclipse, right? 或者 am i just dreaming?
