That's the thing, though--first, why would God have made it so difficult and unsanitary to begin with for his children (though if that Tower of Babel story is to be taken into consideration, mankind builds this great tower to show their power and everyone speaks the same language and there are now wars...so God says "Screw THAT, you're getting high and mighty, how dare you do so well to build towers and have no wars, I'm shattering that tower and making you all speak different languages, thus ensuring war and destruction THAT'LL teach ya to dare question my Godhood by...building an enormous tower...and not killing one another...which is a sin...but ANYWAY, BOOM!"
But even if we allow for the fact that the OT, for all it's horrors and wrath, WAS designed for a very ancient time by a then-semi-nomadic people in the Hebrews, so sanitation and what to eat and all that really was important...why put it in your HOLY Book? Or, if we want to play to both ideas of the Bible's construction, why would GOD decided to put his Word on the subject in his HOLY Book? It's not as if that was the only book for the Hebrews, they put tons of their history and cultural ideals into The Talmud (which actually I think is worthwhile...maybe I'm biased a as a Jew here, but at least that's a history, it's a slanted and corrupted history but no more so than Herodotus or Pliny and the other Greco-Roman historians, and it's nice to have a not-solely-religious account of those years and that group of people...) so why not put the food ideas in there? Or better still, since they had a Holy Book and History Book in the Talmud, at the risk of sounding cliche...why not have a Cook Book?
ESPECIALLY if we're supposed to take that as God's word...after all, if YOU were an Almighty, All-Benevolent (though your mileage might vary on that one) God, and you were dictating your Word that you'd want your people to know for eons to come...are cooking instructions really all that holy and important? Maybe some room instead to, say, give a logical reason to go with the faith-baed reason to believe in you, or at leat give some explanation why when Adam and Eve were about to eat the Apple you out in the Garden, and you knew their doing so could damn your creation forever, you didn't slap their hand away like a parent slapping a five-year-old's hand away from a fire as they don't know any better (and if we're to take they were totally innocent before the Apple, and God's the Father of Creation, I think that's a fitting analogy, any good human parent, free will or no, would slap their little five year old's hand way if they were about to scar themselves forever over an open flame...why not God?) or why you made man have different languages to ensure war when there was none and they were peaceful, and the one side affect of that is they DARED feel powerful and build a huge tower to show their power?
