Well, as I said the symbolic language Christ used wasn't that uncommon in the middle-east of that era. So there's real odds that the crowd was being deliberately obtuse when they rejected his teaching; a conclusion bolstered by the fact that number of his disciples abandoned him afterwords, with the implication that they understood what he had meant.

You see the language of eating and drinking was a common metaphor for making an idea or concept a part of yourself (most of the mosaic dietary law was based on this metaphor, as the animals you were and weren't allowed to eat were used to represent certain lifestyles). Christ talking about eating his flesh and drinking his blood was simply taking that metaphor to its' logical extreme, a call to internalize his teaching in the most absolute way possible.

I'm unsure of my word count, so I'll leave it there.
