The campaign against saturated fat was itself spearheaded by the vegetable oil and processed food industries. I remember hearing a series of CBC radio broadcasts about this a number of years ago, and the role played by these industrial interests in shaping a pseudo-scientific nutritional consensus was striking. All that nonsense about how eggs will kill you, etc. etc., which was foisted on the public for a generation, was propaganda.

It seems the ship is now slowly being righted. The OP looks like a great example of this. I wonder how much mainstream attention it will pick up.

Edit: one interesting thing I remember from that radio series, which does not often get mentioned, is how much fear people had about heart disease in the 1950s and 60s. The meme of the seemingly-healthy middle-aged man who suddenly drops dead of a heart attack no longer has the power it once did. (Other fears have taken its place.) But in the early days of the campaign against saturated fat, this fear was widespread and highly exploitable, and it was deliberately and very successfully exploited. (This, at least, was what the radio program argued, credibly to me at the time. I'd like to hear it again.)
