Our food supply provides a poor supply of vitamins because the land doesn’t rest, getting a natural resupply of nutrients. My wife and have had so many blood test and take supplements based on the results. Vitamin D is now on my low list, moved to Idaho from Florida and lets just say I don’t get the same amount of exposure to the sun.
If you found a doc who looks at your nutrition levels in blood, hang on tight as you have likely found a good doc
Show me some numbers to back up the suggestion that people are actually malnourished in the US. We actually have better bioavailability of essential vitamins and minerals through fortification programs (look at the vitamin profile of white bread some time) and have for most of a century.
The blood tests you took, how were they administered and what guidelines were used to assess nutritional deficiency?
I don't know why anyone is looking at our vaccination rates and thinking that the problem is that people would be healthier if we just told them not to be fat and to eat better. Everything in media overwhelmingly tells you to not be fat, to the point where any message other than "fat people are ugly and dumb" stands out, and is pretty frequently called out. Further, there is no shortage of people promoting supposedly healthier diets. I can't spend 30.minutes on the elliptical without seeing at least 2 different commercials for a diet, supplements, or weight loss programs. Honestly I don't know how anyone could exist in the US and think that the problem is that people just aren't getting the message that they're probably fat and need some kind of supplement or diet change. If you're going to say the problem is that we don't.get that message enough, I have some serious doubts about how well you have thought that through, and how effective yet another media campaign would be.
I'll broaden my reply to briefly mock the statement that hospitals don't make any money off making people healthier. A hospital is probably one of the very few places that keeps an actual panel of nutritionists employed as part of the care routine. But hospitals are not regular medicine, they are by their very nature the last line of defense.
Now if you ask me we could eliminate the profit motive in medicine by just nationalizing all of it. Anything short of that, there's always going to be a profit motive for somebody. That would include repealing the current exemptions that allow "supplements" not to be regulated as food or drugs by the FDA. Make dietary supplements subject to the same rules as drugs with regard to proving that they are in fact effective at treating the condition they claim to treat and I wager you'll quickly see an end to the supplement industry. Make it illegal to advertise drugs, and make the government (the people) the primary shareholder if the not the sole shareholder in every pharmaceutical company, the sole insurer, and the sole employer of healthcare workers. Tada, no more profit involved. Bonus, it's much cheaper to employ doctors and we can afford to maintain surplus capacity of workers beyond what's profitable!
Bonus for the "blame obesity" people, we could end our corn subsidy programs. I'm sure everybody can agree that's one of the fastest ways to stop having corn syrup in everything. If we really wanted to act we could spend some money taxing fast food and subsidizing healthier eating.
Of course this would interfere with the free market, end a significant number of profitable grifts (go look at how many dietary supplements are manufactured by drug companies and their subsidiaries), and it would immediately be decried as communism. Strange too that the "small government" wing of our political sphere never seems to talk much about ending our corn subsidies or restructuring our farm subsidies to make people healthier. I will wager that these fairly obvious steps are for some reason not popular here, despite how effective they are at addressing the problems that we do agree exist.
