True. And while it is also true that association does not prove causality, lack of association is a pretty good proof of non-causality. It is particularly telling when you commission a major study with the idea of supporting your hypothesis and the study fails to show the expected association.
Keys knew that, which is why, when he actually studied twenty two countries, he only reported on the seven countries that supported his hypothesis. Harcombe’s re-analysis of all the data showed that the effect Keys puported to find was actually non-existent.
He admitted that dietary cholesterol had no effect on serum cholesterol, which is partly why he then focused on saturated fat in the diet, instead. Teicholz has mentioned this in several lectures, but I thought she also put it in the book. So much for keto clarity, huh?
