Study Compares Menu Items in U.K. Restaurants With and Without Calorie Labels

U.K. researchers have published the findings of a comparison of calorie counts on menu items in restaurants that feature labeling of those counts and in restaurants without such labeling. Dolly R.Z. Theis & Jean Adams, “Differences in energy and nutritional content of menu items served by popular UK chain restaurants with versus without voluntary menu labelling: A cross-sectional study,” PLOS One, October 16, 2019. The researchers compared offerings from “the 100 most popular UK restaurant chains by sales” and found that 42% of the restaurants offered nutritional information, and 13 of those voluntarily provided menu labeling. The researchers were reportedly able to establish that restaurants that provide calorie labeling on menus offered food with 45% less fat and 60% less salt, though they could not identify whether the labeling caused the companies to formulate products with lower fat and salt contents.
