The USDA food pyramid has been inadequate since its inception in 1992. It is accepted that each day we need to consume protein, fat, and carbohydrates, in addition to the 8 essential amino acids, a lot of water, and some vitamins and minerals.

Below is a sampling of these alternative pyramids, some helpful, some witty, and some literally flipping the pyramid concept on its head.

Each image demonstrates the brilliantly iconic form of the pyramid, while also exposing the limitations of trying to encapsulate a diet in an isosceles triangle. These are just the tip of the iceberg.
