>>109083534when it was written, not eating shellfish or pork or a lot of the other stuff made sense - some of it is holdovers from long-forgotten religions and cults that pre-date judaism by millennia (jews in the modern sense, rather than the biblical we-were-here-first sense Jesus liked to ramble on about, date at the earliest from about 600BCE)
and of course these people lived in climates where food spoiled in hours because of the heat, so pork and shellfish, which any good chef will tell you need a little extra care in the walk-in, would give you food poisoning so often (which again, you know, we're talking about a world where nobody understood hydration and illness at all) that it just wasn't worth eating, so to stop the whiners going "but why" they said "because god said so"
i mean, refrigeration's been around a while - in various forms a few hundred years - but back then? nobody was really doing anything you'd call refrigeration or observing a cold chain from slaughter to table
