Keys’ Lipid Hypothesis “Made Out of Whole Cloth”

http://high-fat-nutrition…on-between.html

Gary Taubes (Good Calories Bad Calories) and Tom Naughton (Fat Head) both pointed it out, as have others I’m sure, but Peter’s charts add a nice crescendo to the chorus. What am I talking about? Nothing less than the biased, incompletely used data upon which Ancel Keys built his infamous, notorious, and utterly bogus lipid hypothesis. It’s a solid example of confirmation bias and scientific chicanery reigning supreme.

As if that wasn’t bad enough, just imagine how many people have been sick or gone to an early grave because they were following the resultant bogus advice that comes out of the lipid hypothesis, which is to say nothing of the wealth that has been utterly wasted trying to support both research into a bad hypothesis and the healthcare of an increasingly sick population paranoid about eating fat (While getting fatter every day eating more and more “whole grains”)!

Rant over.

The gist is that Ancel Keys ignored the entirety of a study and handpicked the data that would support his lipid hypothesis. You can read about it in Taubes’ book. You can watch a great, animated snippet illustrating the legerdemain compliments of Tom Naughton (youtube: http://www.youtube.com/watch?v=v8WA5wcaHp4 ) or you can dive into the charts from Peter.

Here’s a snip from the latter:

OK, this is the graph of heart deaths plotted against fat intake, produced by Ancel Keys in 1953. It’s a beautiful curve, utterly convincing to any Congressperson looking to find fame by funding a cure for heart disease:

. . . Slightly less convincing is when the choice of different countries from the same data bases suggests that dietary fat has nothing to do with heart disease and that heart disease is very rare anyway . . .

So let’s stop playing and look at the whole database from which Keys carefully selected his six countries:

OK, there IS a correlation. It’s pathetic, especially compared to the original line swept in by Keys. Of course things get worse if you add in the Masai, the Inuit, the Rendile, the Tokelau and a few others, shown as red dots:

At this point you would have thought that the name Keys would have become a joke and people would simply have ignored him as a self publicising evangelist with scant respect for the truth. But Keys was nothing if not determined.

There’s even more chart-making sleight-of-hand if you’re curious. Sad “science.” We can only hope that one day the verdict of “guilty” on fat is overturned.
