A British company called Tolerance set up this website, which "seeks to lift the barrier of ignorance which prevents people from enjoying the food of the capital [London] and from exploring new cuisines."
The website invites you to "select a religion," offering a choice of nine, then to "select an area" - North London, Central London, West London, etc.
Up come the restaurants in that area that suit your religion of choice, along with symbols showing which other religions can find their food there.
It's interesting, isn't it, how all these rules and prohibitions and forbidden foods have arisen over time?
Back in the day, when cavemen were cavemen, there was very little discussion given to food preferences, I'm almost certain.

"Og not like mammoth meat! Og eat only fruit and veggies!"
"Urgh?"
"Nnnh! Well, okay, sometimes Og eat little bit of fish. But Og still like to think of self as vegetarian!"
All joking aside, cave paintings indicate humans already had profound religious beliefs even back when more of us were cave dwellers. So it's quite possible that cave people did have food preferences of one kind or another. Perhaps not so rigid or sophisticated as modern food preferences, but no less significant to their quality of life.
