The nutritional quality of restaurant foods in Canada is not monitored by government and limited research has evaluated the nutrient content of these foods. Given the increasing proportion of foods consumed outside the home, this study aims to assess levels of nutrients of public health concern in Canadian fast-food and sit-down restaurant menu items.
Levels of calories, saturated fat, sodium, and sugar of 10,285 menu items from 90 national chain restaurants in Canada were assessed. Data were collected in 2016, extracted and analyzed between 2018 and 2020, and presented overall and by category. Levels in fast-food and sit-down restaurant establishments were compared.
Overall mean levels of saturated fat, sodium, and sugar were high. Entrées contained on average 52% of the total daily value for sodium (1,256 mg/serving) and 45% of the daily value for saturated fat (8.9 g/serving). Beverages and desserts had high levels of total sugar (mean=44 g and 32 g/serving, respectively) but tended to be low in sodium. Sit-down restaurant items had significantly (p≤0.0001) higher levels of calories, saturated fat, and sodium overall, although fast-food restaurant items had higher average sugar levels because of the higher number of beverage and dessert items.
Levels of nutrients of concern in Canadian menu items are excessive among most food categories. As the frequency of eating out in restaurants rises, government policies to promote reformulation and increase transparency of the nutritional content of these items are required to reduce their negative impact on public health.
加拿大政府并未对餐馆食品的营养质量进行监测,而且针对这些食品的营养成分含量,相关研究也十分有限。考虑到人们越来越多地在家庭以外的地方就餐,本研究旨在评估加拿大快餐和坐式餐厅菜单项目中具有公共卫生意义的营养素水平。
评估了加拿大 90 家全国连锁餐厅的 10285 个菜单项目中卡路里、饱和脂肪、钠和糖的含量。数据于 2016 年收集,2018 年至 2020 年期间提取和分析,并分别进行了总体和分类呈现。比较了快餐店和坐式餐厅的水平。
总体而言,饱和脂肪、钠和糖的平均水平较高。主菜平均含有 52%的钠(1256 毫克/份)和 45%的饱和脂肪(8.9 克/份)的日推荐值。饮料和甜点的总糖含量很高(平均分别为 44 克和 32 克/份),但钠含量较低。从总体上看,坐式餐厅的项目卡路里、饱和脂肪和钠含量显著更高(p≤0.0001),尽管快餐店的项目由于饮料和甜点项目的数量更多,平均糖含量更高。
加拿大菜单项目中大多数食品类别中,人们关注的营养素含量过高。随着外出就餐频率的增加,需要政府制定政策促进这些食品的配方改革,提高营养成分的透明度,以减少其对公共健康的负面影响。
