PLOS MED:近7000万次交易提示,实施卡路里标签后人们外出就餐情况

2021-07-22 MedSci原创 MedSci原创

卡路里标签与快餐的平均卡路里和营养成分的小幅下降有关,这些变化意味着卡路里标签与美国连锁餐厅购买的膳食质量的小幅改善有关。

随着全球饮食模式越来越多地转向增加外出就餐,需要采取各种策略来促进零售环境中的健康食品选择。为了提高透明度和鼓励健康饮食,许多国家已经引入或实施了营养标签政策,如菜单标签、包装前的营养披露、警告标签等。

卡路里菜单标签,要求食品店公布菜单上的卡路里含量,就是这样一个策略,已经在一些国家实施,包括美国、韩国和沙特阿拉伯。当其他国家考虑通过或实施类似的菜单标签政策时,需要更多关于它们对顾客膳食选择的影响的真实证据。

2018年5月,美国食品和药物管理局要求在分店数量≥20家的餐饮场所实施卡路里菜单标识。一些研究发现,标签后消费者购买的卡路里或营养素含量没有变化,但对零售交易的大型数据库的研究检测到膳食的卡路里含量略有下降。

然而,在美国全国范围内实施这一政策后,没有任何研究对这些关联进行研究。在全国范围内的实施可能改善了顾客购餐的情况。为了提高了人们对该政策的认识,并鼓励更健康的购买,来自哈佛大学公共卫生学院的专家开展了一项全国性的调查研究,结果发表在PLOS Medicine杂志上。

研究人员从美国3个州(路易斯安那州、密西西比州和德克萨斯州)的104家快餐连锁店的餐厅获得了每周汇总的销售数据。该专营店提供了从2015年4月到2019年4月的所有销售数据。该特许经营店在2017年4月对菜单进行了标注,比美国食品和药物管理局规定的2018年5月的全国范围内的实施日期提前了1年。

从Menustat获得了所售物品的营养信息(卡路里、脂肪、碳水化合物、蛋白质、饱和脂肪、糖、膳食纤维和钠)。这是一个公开的数据库,包含了美国顶级创收餐厅连锁店所提供物品的营养信息。研究人员使用了一个中断的时间序列来寻找特许经营和全国范围内的标签后每笔交易的平均每周卡路里和营养成分的水平和趋势变化。

全国范围内实施标签后,每笔交易的平均购买卡路里的水平和趋势变化。

分析样本代表了在67112342次交易中购买的331776445件物品。总的来说,特许经营标签与每次交易平均卡路里减少54kcal有关(95%CI:-67~-42),但随后每4周会增加3.3卡路里/交易(95%CI:2.5-4.1)。

全国范围内的政策实施与每次交易平均卡路里减少-82kcal有关(95%CI:-88~-76),随后每4周内会继续下降2.1kacl/交易(95%CI:-2.9~-1.3)。在研究结束时,基于模型预测的平均卡路里/交易量降低了4.7%(变化=-73kcal/交易,95%CI:-81~-65)。

特许经营卡路里标签实施后(2017年4月)和全国范围内卡路里标签实施后,每笔交易购买的平均卡路里和平均营养素的变化

此外,营养素/交易量比我们在没有实施标签时预期的低1.8%(饱和脂肪)到7.0%(糖)。

综上,卡路里标签与快餐的平均卡路里和营养成分的小幅下降有关,这些变化意味着卡路里标签与美国连锁餐厅购买的膳食质量的小幅改善有关。
