You're not wrong there, but it's also not accurate to say it's THE driver for increased health care costs.
Price signals which work so well in the rest of the marketplace are skewed by healthcare regulation and regulatory compliance carries a huge cost. Take the role of "billing specialist" for one example. The one and only reason for the proliferation of that craft is to deal with Medicare and Medicaid requirements, which the health insurance companies all too happily require as well. With the blessings of the US congress as well as the state legislatures, they exist in a market closed to competition. Then there's regulatory capture and the revolving door between places like NIH/FDA and Phizer, GSK, Bayer, and all the rest.
Ever heard of a concierge medical practice? Average cost of annual membership is somewhere between $2000 and $5000. Not cheap. But you also generally get unlimited visits with your doc, and they actually take the time to sit down and discuss your concerns with you. In standard internal medicine practices, many of those docs need to see 40 or 50 patients per day to make their nut.
I've come to believe that most of the chronic issues people have are diet-related - food being another heavily regulated industry suffering from massive regulatory capture. Eat meat and greens to your heart's content; complex carbs sparingly; simple sugar and processed food not at all - to include ultra-processed seed and vegetable oils like canola, corn, saffron, and the like. Poly-unsaturated fats are just poison. Stick with animal fats like hog lard, beef tallow, butter, duck fat, bear lard, and mono-unsaturated fats like olive oil, coconut oil, and avocado oil. IOW, shop the outer edge of the grocery and skip the rest.
Since I went near total carnivore about 3 years ago, my HDL has gone up from about 45 to 74, my triglycerides are down from over 200 to 75, and LDL down from over 200 to 120, and I no longer need to take blood pressure meds; and I'm down from 265 to 225. My doc did a full body ultrasound on me last year, my pipes are as clean as a healthy 30 year old, and I was 55 at the time. My heart's ejection fraction is 72% - normal for men is 52 -72%. Since I gave up all the processed shit, my knees, hips, and shoulders rarely hurt anymore. I used to take a lot of daily ibuprofen for all of that. I don't remember the last time I had to take any for joint pain. I've had a torn labrum in one of my hips since HS. Even all the walking and crawling and what-not on my safari back in August didn't cause me any discomfort. The acacia thorns tearing at my flesh are another matter.
Ever heard of the Warburg Effect (discovered nearly a century ago)? Most cancers require a steady stream of sugar for the purpose of fermentation, even when O2 is already abundant . When they grow cancer cells in vitro, many of them have to be bathed in insulin so they can absorb enough sugar, otherwise the cancer cells die.
People don't get Type II diabetes from a lifetime of abusing animal fat and protein, they get it from a lifetime of punishing their pancreas with a steady diet of sugar, causing all cells to become insulin resistant over time. Type II diabetes comes along with a number of other comorbidities - obesity, cardiovascular disease, generalized inflammation, metabolic syndrome, etc. Obesity is a non-trivial risk factor for quite a lot of cancers as well.
And of course, the answer for all of this from Big Medicine and Big Pharma is pills. And of course, they and Big Ag have a vested interest in
NOT looking at the dietary angle on any of this.
Apologies, I didn't intend to turn this into a rant. Malpractice insurance is certainly a contributing factor to increased health care delivery costs, but it isn't a big one.
