Andy, bravo! I'm tired of different foods being declared unhealthy, then healthy, then killer unhealthy, then the next craze. The latest one I saw was that heavy drinkers (and I count myself as one) live longer than moderate or non-drinkers. Now, give me a break. Even I'm not that delusional. Anything I read or hear when it comes to food I take with a huge grain of salt. And there's an organization that always over-states the obvious. They've come out with butter is fattening (talking about movie popcorn), sweet and sour pork is bad for your heart, etc; all of which you'd know if you took a home ec class when you were a teenager.
I may be wrong, but I think Andy was rightly skewering misinformation and speculation dressed up as facts rather than making a blanket statement about ALL research or information.
While it's true that sometimes it seems as if scientists and researchers can't make up their collective minds, I attribute that to the evolution of the field itself. We're always learning something new.
It's the non-credible world of rumor-mongers who are so sure of their facts that they will never allow new information or research to get in the way of their latest conspiracy theory.
