Trends in Calories and Nutrients of Beverages in U.S. Chain Restaurants, 2012-2017

Abstract

Introduction: Although beverages comprise one third of all menu items at large chain restaurants, no prior research has examined trends in their calorie and nutrient content.

Methods: Beverages (n=13,879) on the menus of 63 U.S. chain restaurants were the final analytic sample obtained from a restaurant nutrition database (MenuStat, 2012-2017). For each beverage type, cluster-bootstrapped mixed-effects regressions estimated changes in mean calories, sugar, and saturated fat for beverages available on menus in all years and for newly introduced beverages. Data were analyzed in 2018.

Results: Traditional sugar-sweetened beverages, sweetened teas, and blended milk-based beverages (e.g., milkshakes) were significantly higher in calories from 2012 to 2017 for newly introduced beverages (p-value for trend <0.004). For all newly introduced sweetened beverages, sugar increased significantly (2015, +7.9 g; 2016, +8.2 g; p<0.004) whereas saturated fat declined (2016, -2.3 g; 2017, -1.6 g; p<0.004). For beverages on menus in all years, saturated fat declined significantly (p<0.001), whereas mean calories and sugar remained relatively constant. Significant declines were observed for sweetened coffees (-10 kcal, -0.5 g saturated fat, p<0.001), teas (-2.6 g sugar, p=0.001), and blended milk-based beverages (-28 kcal, -4.2 g sugar, -0.8 g saturated fat, p<0.001). From 2012 to 2017, the total number of beverage offerings increased by 155%, with 82% of this change driven by sweetened beverages.

Conclusions: Sweetened beverages available in large chain restaurants were consistently high in calories, sugar, and saturated fat and substantially increased in quantity and variety from 2012 to 2017.
