A new one actually. Here's one of his early, and typically smart, posts on food policy and menu labeling:
The key insight here is that small changes in behavior can have large impacts on outcomes. A Health Impact Assessment (pdf) prepared for the city of Los Angeles estimated that if calorie labeling convinced a mere 10 percent of large-chain patrons to order meals that were merely 100 calories lighter, then menu labeling "would avert 38.9% of the 6.75 million pound average annual weight gain in the county population aged 5 years and older." Get 20 percent to reduce their meals by 75 calories? You've knocked out 58.3 percent of the projected 6.75 million pounds. That's huge.
