I'm suspicious of the medical-pharma-industrial complex in a lot of ways and yes, they do it to themselves. I understand we have to try to adapt to the latest medical science, and science changes. But time after time after time the stuff they preach changes and it is like, oh well, "the science has changed". Take for instance people with high cholesterol being told they can't eat stuff like eggs. Now they can because "they" decided eating high cholesterol foods does not impact your blood cholesterol. No biggie, it is just people have been choking down nasty Egg Beaters for breakfast for 20 years when they could have been enjoying real eggs. Same with beef - was OK, then was bad, now OK. Blood pressure in 65 year old male 130/81 used to be great, now "hypertensive". LDL of 110 used to cause a guy to jump up and down with joy, now candidate for a statin if you can't get it below 100. Doctors used to recommend smoking for throat health, now not OK. And on and on.
