A new study at the UC Berkeley revealed that given menu labeling, most patrons will choose the healthier food options. Faced between a 500-calorie hamburger, or a 120-calorie salad, the numbers might make you feel guilty about what you are eating, and you choose the salad.

Kaiser Permanente, an advocate for healthy eating, will now be the first health care provider to display calorie and nutrition info within the cafeteria menus in their hospital.

My question is, why weren't they doing this before?

McDonald's has had a free menu of their calories for food placed in their restaurants for... how long now? A year at least.
