But you've given away Scott's point. We've been listening to how bad saturated fat is for my entire lifetime pounded into the public with the maximum volume science has available to it at the highest governmental and science authority levels, and now, oops, mea culpa, it's more complicated than we thought, and right now it's not exactly out of the question that "saturated fat" will be entirely removed from the "bad thing" or even "consumed too much by Americans" column in another 10 to 20 years.
No matter how upset you get about people being a bit glib about what the consensus said (and frankly I'm not sure I couldn't establish "science said saturated fat is bad, full stop" with just a bit more effort than I'm willing to put in right now), you can't get out of the fact that the pounding was apparently unjustified, and there's a nontrivial chance it was flat-out wrong. Science and scientists shouldn't expect to escape from those decades of being wrong at maximum volume and the corresponding vicious evils inflicted on the world (because after all the US consensus has been exported all over the world), and it would be utterly and completely irrational for me not to update my beliefs based on this evidence.
Further one doesn't need to look very hard to find "proof" that the "fat = bad" message is prevalent in society.
Go to the grocery store. Go to the dairy isle. Look at the various products. If you can't find "low fat" or "light" versions of most of things there, I would be dumbfounded.
If major corporations have picked up on the "low fat" movement then I think it's fairly safe to say that it's prevalent in society.
