>and ironically it's the animal based fats that tend to be healthier
Got any sources to back up that claim?
The Yerushalmy and Hilleboe paper is usually the study that people quote when they try to debunk Ancel Keys. In that study, they show that there is a distinct correlation between fat as a percent of total calories and heart disease. And they show that animal fat is more highly correlated than other types of fat. (That paper said that Ancel Keys screwed up on methodology, and they re-did with proper methods and found essentially the same result)
Big thing to keep in mind is that the data showed (and still shows) a distinct correlation between animal fat and heart disease. One theory suggests that the true cause is simply how wealthy a given nation is. i.e., wealthier nations eat more animal fat, and wealthier nations have better health care which prevents other types of deaths.
