I came across this slide show from Time magazine on Party Perfect, titled "What the World Eats". I agree that it is a fascinating pictorial showing families around the world with a sample of a week's worth of groceries. Equally interesting is the weekly food expenditures associated with each picture, listed below each one.
The family from North Carolina is probably a good representation of how most Americans eat (sadly). It is crazy to think we spend more than most countries on food, yet we eat the most highly processed foods, and the least whole foods.
