The blame also rests with regulators like the FDA, who for decades promoted a food pyramid that was basically upside-down in terms of what was healthy; who for decades promoted that partially-hydroginated oils (trans-fats) were preferable to natural saturated fats; who encouraged a "low fat" diet that prompted food producers to substitute sugar for fat to make foods tasty and consumers to consume an unhealthy high-starch, high-sugar diet and a nearly manic avoidance of fat.
Remember the FDA is part of the Department of Agriculture and that the Ag department's responsibility is to simultaneously protect the food supply (i.e. make sure it happens, take the farmers' side etc), manage food safety and support public health. Any surprise these objectives are at odds, and which side has more profit attached?
This is like the Department of the Interior whose mission is to protect the environment and to encourage mining. In their case it means oil company employees had did drugs with and had sex with their government regulators (http://www.nytimes.com/2008/09/11/washington/11royalty.html?...)
I am beyond considering this corrupt and simply shake my head that it's fundamentally mis-architected.
There are many ways the government could raise money for a small program like designing the food pyramid. It's really not relevant which one they picked.
