Quite true.
God's law was pretty big on not eating anything gross, washing frequently, not engaging in unsafe sexual practices, not letting the dead go without proper burial, and other rather enlightened concepts of hygiene, which, for a period when they had literal deities dedicated to beetles that crawled around in shit and where being a sick fuck was considered an act of devotion to certain gods, was a pretty forward thinking set of concepts.
However, given the same people who complain about the Bible being unprogressive are likely the same people who live like pigs IRL (and a lot of tropers outright admit to being NEETs), no wonder that goes unmentioned.
