The pyramid being upside down with grain on the bottom and fats and oils being on top is directly from south park.

The only difference is that meat, fat, dairy, fruits and vegetables are grouped together with this new pyramid with grains on the bottom. while south park puts fats -> meat and dairy -> fruits and vegetables -> grains as the order.
