Our body doesn't posess the enzymes to dehydrate saturated fats, therefore we can't process them as efficiently,
Additionally saturated fats lead to cell membrane instability and 'crystallisation' due to the straight-line chemical arrangement of the carbon atoms.
Cis - (A type of) unsaturated fats by contrast, have kinks in the chains which induces fluidity into cell membranes. Interestingly Cholesterol is used to maintain membrane stability/'fine-tune' membrane fluidity when there are lots of Cis fats.
I haven't listened to the whole talk yet and take it the poster's angle is that there is a lot more to diet, nutrition and preventable diseases like Ischaemic heart disease than just 'saturated fats and cholesterol'. Yes. No doubt. But they are still terrible for you in high doeses, Epidemiological studies have shown this beyond a doubt and the basic science is sound.
