As I see it, the point of this new pyramid is not to add more emphasis to meat specifically, but to undo some of the past vilification of fat (note the emphasis on whole milk and full fat dairy), and to move emphasis away from carbs as the basis of the diet. And honestly, I think that's pretty much correct - the low fat movement was a disaster for our collective health, because food manufacturers added more sugar to compensate for the bad effects on taste that that has, and because if you eat a good amount of full fat stuff, there's not nearly as much need to snack between meals.

If you go to Western Europe, they're not drinking lots of skim milk, and if you eat things from the bakeries, there's more butter and not as much low quality vegetable oil or sugar. When my French cousins come here, they find lots of the stuff sold here revoltingly sweet.
