The majority of food expenditures are made in supermarkets and this environment influences our purchasing and food intake. Breakfast cereals are frequently marketed as healthy food choices. The objective of this study was to examine the frequency of in-store promotions for cold breakfast cereals in Canadian supermarkets and to determine whether healthier or less healthy breakfast cereals are promoted more frequently.
Data was collected once per week over a four-week period from a convenience sample of the five largest Canadian supermarkets in the Ottawa/Gatineau area. Data collection included the number of shelf facings, promotional displays, and the cost of cereals/100 g. The UK Nutrient Profiling Model was used to determine the healthfulness of each breakfast cereal.
29.8% (n = 67) of the 225 unique cereals were classified as healthier and 70.2% (n = 158) were classified as less healthy. Less healthy cereals were displayed at eye level, in the profitable middle shelves, 2.9 times more frequently than healthier cereals. There were 5.3 times more breakfast cereal shelf facings, 4.2 more end cap displays, 1.7 more mid-aisle displays and 3.3 more special pricing signage for less healthy cereals compared to healthier cereals. Less healthy cereals had a significantly higher average total number of shelf facings compared to healthier cereals (t = -4.28 (280.8), p < .001).
Breakfast cereal manufacturers need to consider reformulation of their breakfast cereals to improve their healthfulness and supermarkets need to increase the marketing of healthy breakfast cereals within their stores.
大部分食品支出都发生在超市,而这种环境会影响我们的购买行为和食物摄入。早餐谷物经常被作为健康的食物选择进行营销。本研究的目的是调查加拿大超市中冷早餐谷物的店内促销频率,并确定更健康或不太健康的早餐谷物是否更频繁地得到促销。
在四周时间内,每周从渥太华/加蒂诺地区五家最大的加拿大超市的便利样本中收集一次数据。数据收集包括货架陈列面数量、促销展示以及每100克谷物的成本。使用英国营养成分剖析模型来确定每种早餐谷物的健康程度。
225种独特谷物中,29.8%(n = 67)被归类为更健康的,70.2%(n = 158)被归类为不太健康的。不太健康的谷物在与眼睛平视的位置、利润较高的中间货架上的展示频率比更健康的谷物高2.9倍。与更健康的谷物相比,不太健康的谷物的早餐谷物货架陈列面多5.3倍,端架展示多4.2个,过道中间展示多1.7个,特殊定价标识多3.3个。与更健康的谷物相比,不太健康的谷物的平均货架陈列面总数显著更高(t = -4.28(280.8),p <.001)。
早餐谷物制造商需要考虑重新配方以提高其健康程度,超市需要在店内增加对健康早餐谷物的营销。
