Greek actually has several words that are translated as "eat" in English throughout the New Testament, some being more specific then others, so the question of "eating" can be addressed only in specific verses and not in general.
But I am quite sure that the verb used for eating of Christ's flesh was not allegorical at all.
And we all know that a significant and rudimentary part of the Church back then must have been Greeks and Greek speakers like Luke so that must have affected the topic at hand.
