Yeah, it is turning around to some extent now, particularly in relation to butter and full fat dairy products. Recent studies have identified some negative health outcomes associated with low fat dairy products (but not with full fat), and more and more people are starting to realize that they've been conned. Here in Australia the price of butter has soared (after being extremely cheap for many years as you say) from about 80c up to about $2.40 for the same per 250g pack! That's a 3x increase over just a few years. So people must be waking up to it.
Apparently the rise in butter prices isn't solely due to increase demand for butter per se (though that has increased), but more so due to the demand for other full fat dairy, and decline in low fat and skimmed products, which has greatly reduced the opportunity for processors to get hold of the required dairy fat.
But still the advice "... and avoid saturated fat" never wavers.
