Without values, we can pretty much say that anything increases odds of disease: walking, driving, eating, shitting, sleeping.

And what's to gain? Hysteria because there's a million ways to die? Or increased distrust in health recommendations, as they're barely actionable?

I think the current recommendations are: do exercise, eat well and get good sleep. They should get you a good baseline. But you don't need to be a fundamentalist: you don't need to obey them 100% of the time!
