The article “Health law to put calorie info on vending machines” [News, Dec. 29] presents an incomplete picture of the effectiveness of calorie labeling.
Our study in King County was the first long-term look at the impact on customers’ choices of including calorie information in menus. We found that at 18 months post-regulation, calories purchased decreased. (Previous studies including the New York City study cited and our study show that 6 months after requiring labeling, calories purchased did not change).
