This chart linked by barrelstrength compares what Americans actually eat (the blue) with what the USDA says they should be chowing down (the yellow). We seem to get only potatoes right. Are you surprised we drink more fruit juice and eat more cheese than counselled? And as barrelstrength points out, most veggies don't make the grade. Are hundreds of millions of free-choice citizens wrong while some thousands of USDA employees are all in the right? I doubt it.
