You only only see what they want you to see. Do you know food in the EU costs a lot more than in the us (most of our agriculture and meat producers, dairy/chicken farms and graineries are subsidized by the USG! Their food is much healthier and tastier than the commercial crap here ( fruits, vegetables, meats, foul, dairy products...) consequently, they are healthier, and their health care costs much lower. You are hat you eat, or eventually a bad diet will translate into poor health.
Im no food saint, but I eat a lot healthier than the 60 something yo people I grew up with, or know. And I cured a 30 year long debilitating incurable disorder that the paid health care system could not, or didn't care to figure out. Bit of both probably
That forced me to delve into diet, and alternative therapies like; liver cleanses (essential, even if you're healthy), and a variety of holistic treatments, none of which are covered, but did nothing. Solving this critter wasn't easy. It took me 5 years spending every spare dollar all out of pocket, and without the heath system, which sucks paid, or unpaid
