Well said. The media and most of the public are quick to confuse correlation and causation when it suits their pithy narratives ("drinking red wine will make you healthier!"), or which makes life easy. But they/we bury their heads in the sand when it comes to the correlation for increases in disease, chronic conditions and mental health issues. Nothing to see here! (Note - high correlations in those problems doesn't mean we know what caused them, but those correlations are a very good sign that more time should be spent trying to figure out those causes.)
@wnelson14 said above that doctors should be paid for fixes. I expect that would take an overhaul of the medical and insurance systems, but why isn't it possible? We put men on the moon, so why can't we figure out a system in which insurance helps to subsidize good food? (This is rhetorical - money is the answer as to why.) And a system in which doctors are paid
more for patients who come in for preventative care? (You can find those doctors, but the way the system works now, I have to pay mine out of pocket for that approach.) I know there are some things on the margin - like I can get some "free" money put in my HSA if I answer some questions and provide my weight, and some other basic stuff - but that is pretty limited (maybe $200 IIRC).
BTW, my concierge doctor is very good, and while we agree on many things (including the irrelevance of my "good" and "bad" cholesterol numbers), he didn't like my idea of a few years ago of getting a continuous glucose monitor ("you're not sick or even pre-diabetic, so don't waste your money"). The Casey book mentioned by the OP goes into some detail, so I'm going to revisit the idea with him.
And as far as "wasting money" - that guy has no idea how good I am at wasting money, and how trivial a CGM cost is in relation to the addictions fostered by Rokslide.
