To 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.
Menu 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 healthier v. less healthy items. Changes over time in NPI scores and energy of promoted foods and beverages were analysed using linear regression.
Four hundred fast-food restaurants (McDonald's, Burger King, Wendy's, Taco Bell; 100 locations per chain).
NPI of fast-food items marketed at fast-food restaurants.
Promoted 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.
Foods, and to a lesser extent, beverages, promoted on menu boards and signs in fast-food restaurants showed limited improvements in nutritional quality in 2013 v. 2010.
研究 2010 年和 2013 年美国四家快餐连锁(麦当劳、汉堡王、温迪和塔可贝尔)菜单中推广食品的营养质量。
在美国各地的 400 家快餐店记录招牌和菜单板上的食品。使用营养成分谱指数(NPI)来计算食品的整体营养得分(得分越高表示营养质量越高),并将其分为更健康和不太健康的两类。使用线性回归分析 NPI 得分和推广食品及饮料的能量随时间的变化。
400 家快餐店(麦当劳、汉堡王、温迪和塔可贝尔;每家连锁店 100 个地点)。
在快餐店推广的快餐食品的 NPI。
一般菜单板和招牌上推广的食品和饮料在两个时间点都低于“更健康”的标准。在一般菜单板上,2010 年至 2013 年,图片上的食品略有改善,NPI 得分增加(平均值(SE))3.08(0.16)点(P<0.001),能量减少(平均值(SE))130(15)kJ(31.1(3.65)kcal;P<0.001)。除塔可贝尔外,所有连锁店都呈现出这种模式,因为图片上的食品能量增加。儿童区的图片食品显示出最大的营养改善。虽然一般菜单板和招牌上推广的食品在营养质量上有所改善,但饮料的情况保持不变或变得更糟。
2013 年与 2010 年相比,快餐店招牌和菜单板上推广的食品,尤其是饮料,其营养质量的改善有限。
