very similar to modern day food prep techniques
can you give me examples? It may well contain food prep techniques that were widely accepted at that time and discovered through trial and error in other cultures anyway.
People with contagious diseases were also isolated
According to the bible the cure for leprosy is pretty much taking a bath and chucking a bit of bird blood around. Why don't we do this now? Why couldn't god have explained bacteria?
Diseases are the result of the Fall, original sin, which were then inherited
So who actually created the bacteria and viruses that actually cause disease?
Not following God's will for our lives is inherently bad for us
But god has also provided a way for us to avoid the consequences of not following him?
The thing is, we don't need a god to explain what we see around us, putting a god in the picture is entirely unessecary and illogical. I'd need a very good reason to attribute it to a force that we just don't need to (and have absolutely no evidence for) from a basic knowledge of the facts in front of us. Put it like this. It seems to me that if there is no god, things would have developed the same way and we'd be at the same point anyway.
