Modern dietary guidelines still put breads at the bottom, the Harvard Healthy Eating Pyramid is a really good version of the "pyramid infographic" style of nutritional guidance. There is some evidence the old US food pyramid guideline of 5-11 servings of grains were influenced by lobbying from the food industry, however by my calculations 5-11 servings of grains is pretty much necessary if you follow the AHA's optimal health guidelines of 300 minutes of cardio per week. If you look into the history of how the US food pyramid got made the biggest influence of industry lobbyists were on the meat and dairy recommendations, changing "no more than 2-3 servings" to "2-3 servings a day" and removing red meat from the "sparingly" peak at the top of the pyramid.
