Were the Egyptians in the story of Joseph vegetarian?

[durabone]

Shane's post here reminded me of an old question.

Cain and Abel, being the two sons of Adam and Eve who have been cast out of Eden, merely symbolize the two main forms that the control system took in order to perpetuate conflict. Both ways contain within them implicit ownership of something, either cattle or land, and both suggest the use and manipulation of the earth for their own benefit, and to the detriment of the Great Mother. The only reason Abel was glorified by the Hebrews was because it was their way of life.

Does anyone remember any posts here about the idea that the Egyptians in the story of Joseph may have been vegetarians? Thanks.
