Well, first thing to note is that saturated fats may in some increase some fraction of cholesterol, the thing is - who cares!
Cholesterol is not the bogeyman you may have been led to believe it is. There is for instance no correlation between patients admitted to ED with acute myocardial infarction (heart attack) and their level of cholesterol - if the hypothesis were true that cholesterol causes heart disease, the result would be skewed towards high cholesterol. Cholesterol is (mostly - with the exception of some genetic variants) a sign of inflammation, the attempt of the body to fix things.
The main issue with PUFA is oxydation - or in another term, they turn ‘rancid’. That is why a lot of those PUFA need to be chemically treated/ processed to be palatable, and to remain so over the (prolonged) shelf life of the product.
Most dieticians are still wed to the old Keysian ‘Lipid Heart Disease Theory’ - this theory has been shown to be incorrect at least 30 years ago, if not longer.
Well my dad has high cholesterol problems and high blood pressure, not to mention an excised gall bladder, and I've been looking to see if a keto diet and consuming saturated fats would be beneficial for him, but I'm sure his doctor would disagree. Would keto work for him or people like him?
