Could it possibly be that there is a corner of the internet where friendly discussion can take place?
I hope so - If I come across as thinking that I know anything, I don't feel it. All of this is fiendishly complicated, and I find that trying to explain a thing is the best way to learn how little you know about it.
And lots of topics all of a sudden..
On whether the link between saturated fat and heart disease has ever been proven; I'll choose my words carefully. The most obvious point is that in 2006, the biggest study of it's kind - the Women's Health Initiative, set out to do exactly that (partly because of this ongoing argument) - and concluded quite the reverse. "The diet had no significant effects on incidence of CHD"
More broadly - it's a difficult thing to prove. In most of science, you forward a hypothesis, then try to dis-prove it - if you repeatedly cannot, then it's likely to be true, but if you disprove it once, it's false. It really is true to say that no study has proven a causal link.. there are many that appear to do so... but you can (and I have, and there are many sources that will go through a history of all studies done) see that there is a history of trying to 'show' the right data to make the case, not try to disprove.
The most glaring example is the famous seven country study, that shows quite a striking connection between levels of heart disease and consumption of saturated fat. Really conclusive, to the point that you can only agree with the 'this is a known thing' perspective. Except, inconveniently, if you know that at the time, data for 23 countries existed, and if you plot them all, the full picture proves absolutely nothing.
So - especially when you understand that even the initial trial results that underpin all of this, published by Ancel Keys, were careful to state that this was an association, not a proof, and further that when you realise that people involved in those studies went back after the event and showed that sugar consumption was a better statistical fit to the data.... it really is factually correct to say that the link between saturated fat and heart disease is still an unproven working hypothesis.
@HairySmurf - I congratulate you on hitting your weight goal - bravo. I am also prescribed Statins, and this is very much a bone of contention with my GP, because I stopped taking them. I kind of feel like Pfizer are quite happy for us to all take moderate to high levels of statins and then eat what we like, but I'm not sure it's a very good plan.
The main problem with Statins is that they require the saturated fat hypothesis to be true, and if it isn't, then there are well studied risks.. most obviously about an equal risk of developing Diabetes (statistically compared to the benefit in terms of reduced risk of CHD). And a 1 in 20 risk of muscle problems, and a long list of additional risks. I would point you at Dr Malcolm Kendrick on that one...
I dropped in to his blog to see if there was any link to the 'Rice Diet' - which I agree on the face looks interesting (at least within the confines of what you could get away with in 1937) - and his comment was simply, "Let us see if anyone else can replicate this work." - which says it better than I can.
I don't think I have a problem with the study that shows an increase in LDL receptors with increased fat consumption of any kind; that would be totally normal. The problem is the assumption that it's a bad thing... Every cell needs Cholesterol to function, and LDL receptors are what trigger LDL particles to engage with the cells, and drop off their load of Cholesterol - they are only transport vessels for that purpose. But they are constructed in the Liver. The lower intestine will create Chylomicrons from dietary fat. Plus, the Cholesterol present in them is different from then crystalline Cholesterol present in blood clots that become Plaque.
