Image of the Week: World War II-era food wheel

With obesity rates over 20 percent in all but one US state, nutrition is, understandably, an often-discussed topic. The USDA even recently revamped its traditional "food pyramid" in an attempt to provide more modern nutritional standards for 21st-century Americans.
