"Isn't that basically what we've been doing with dietary guidelines since the 80s?"
If by this you mean to ask if the new guidelines are the same as previous ones from the 80s, then no. The new pyramid is different, makes different recommendations (more meat, for instance, and less wheat and grains). The website linked to explicitly shows how it is different from the previous "food pyramid" guidelines.
No, what I meant was "haven't we been basically ignoring science on nutrition since the 80s?" I think we have.
For those who don't believe me - go find some old family photos of your parents or grandparents, whichever generation would have been young adults in the 1960s or 1970s. Compare them to people of the same age born any time after, say, 1990. Nothing come of one sample, but people from the previous generation just weren't fat in their 20s like we are.
Yes, there's more to it than that. But food is a big part of it.
