Changes in the nutritional quality of fast-food items marketed at restaurants, 2010v.2013

Abstract

AbstractObjectiveTo examine the nutritional quality of menu items promoted in four (US) fast-food restaurant chains (McDonald’s, Burger King, Wendy’s, Taco Bell) in 2010 and 2013.DesignMenu items pictured on signs and menu boards were recorded at 400 fast-food restaurants across the USA. The Nutrient Profile Index (NPI) was used to calculate overall nutrition scores for items (higher scores indicate greater nutritional quality) and was dichotomized to denote healthierv.less healthy items. Changes over time in NPI scores and energy of promoted foods and beverages were analysed using linear regression.SettingFour hundred fast-food restaurants (McDonald’s, Burger King, Wendy’s, Taco Bell; 100 locations per chain).SubjectsNPI of fast-food items marketed at fast-food restaurants.ResultsPromoted foods and beverages on general menu boards and signs remained below the ‘healthier’ cut-off at both time points. On general menu boards, pictured items became modestly healthier from 2010 to 2013, increasing (mean (se)) by 3·08 (0·16) NPI score points (P<0·001) and decreasing (mean (se)) by 130 (15) kJ (31·1 (3·65) kcal;P<0·001). This pattern was evident in all chains except Taco Bell, where pictured items increased in energy. Foods and beverages pictured on the kids’ section showed the greatest nutritional improvements. Although promoted foods on general menu boards and signs improved in nutritional quality, beverages remained the same or became worse.ConclusionsFoods, and to a lesser extent, beverages, promoted on menu boards and signs in fast-food restaurants showed limited improvements in nutritional quality in 2013v.2010.
