Bonnie over at Ethicurean created a fascinating infographic for Wired that overlays the price per calorie of various foods with their energy payoff and sugar content.  It depicts what Adam Drewnowski researched and Michael Pollan wrote about for the New York Times: 1. The cheapest available food is often the most fattening.  2. The most calorie-dense foods (usually processed and frozen convenience items) tend to be concentrated in the center shelves of supermarkets.

This supermarket setup seems pretty pervasive - it even holds true at my idealistic, non-profit Food Coop where I spent my monthly shift last night ringing up fancy cheese and (expensive) mixed-drink ephemera like limes and mint for people's New Year's celebrations.  Check out Bonnie's graphic above and, when shopping in the "middle aisles" of your grocery store, don't forget Rambam's "middle way" - moderation.
