The benfits of omega 3s and the balance between omega 3 and 6 are well documented and accepted
Here is what the British Dietetic association says on
Omega 3 and Heart disease (2002)

or food facts fats which describes the different fats and suggests a balance between them.

I've looked at the first 5 articles in the 2nd post (then gave up). Apart from the first one ( a very short trial with mice and chylomicrons which can be found in saturated fats,) The rest are concerned with the various types of oils (rice, grapeseed, olive, fish, flax) benefits of monounsaturated and polyunsaturated fats, omega 3 and 6 fats . and the balance between Omega 3 and 6. None of the articles I read endorsed a high consumption of saturated fat and one warned of caution over the use of coconut oil in the absence of any real research.
As to the establishment backtracking, who and for what?
Governments? Scientists? or food manufacturers?
The history of cholesterol/lipid/cardiovascular/statins is not the same on this side of the Atlantic as that in the US.(we're always hearing about US experience, do we eat the same things, did the British government give the same advice?)
this is one British version of the history, from those who did the research (long and at times difficult for the non specialist)
Cholesterol, Atherosclerosis and Coronary Disease in the UK, 1950–2000 (witness seminar)
