Fat Boy Slim
I have not read the article but I have read a great deal on how the food pyramid was created and why everything is low fat, low fat , low fat....
Ok here goes the story in a nutshell:
When the food pyramid was created the USA was in a crisis of cardiovascular illness (and still is). Obesity had not risen yet, but cardiovascular illness was increasing. There were a few studies done that suggested decreasing cholesterol and saturated fat in the diet led to less cardiovascular illness. To illustrate this to the public the pyramid was created because the dieticians had to consider that some Americans read poorly; so they used pictures.
To eliminate fat, they inadvertantly eliminated protein (because at that time most foods high in protein also contained fats). They also did not know the physiological function of fat other than to say it was an energy store.
....THE END
