Doctors: We were wrong
Below is an excerpt from the latest issue of the "Journal of the American Medical Association". It is about as close as you can get to an official admission that the official diet advice given to Americans for many decades was totally wrong and probably harmful.
The message from that is a hard one: Don't rely on official science about anything. You have to look at the evidence for yourself. I have been reading health and diet advice from the early days of Lelord Kordell (he recommended lots of protein) and my response has always been to eat whatever I like whenever I like it. So at age 71 I have had a lifetime of good dinners and only iatrogenic health problems.
On my reading of the evidence, I doubt very much that it makes much difference what you put into your mouth. The small differences that medical researchers find in their research results are almost certainly as trivial in their importance as they are trivial in their size. The lessons for global warming believers are obvious. Long live good dinners! The planet won't notice one way or the other
