Despite the fact that there are many different "food pyramids" the USDA food pyramid was basically pay to play propaganda, created by various food industries. Also note how I say was because the USDA food pyramid existed less than 20 years and was retired in 2011 because the science became undeniable. Of course the new "food plate" really isn't much better and is still USDA propaganda paid for by the food industries.
