Like, don't get me wrong, RFK will kill N*10^5, N*10^6 people with his outlook on diseases, but....how many people have had their lives wrecked by "fat makes you fat", "ketchup is a vegetable", and "eat a balanced diet composed entirely of sausage, flour, and sugar"? As a GenXer I've been dealing with the echoes of this for a long time.
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.
