To examine parents' beliefs about the meaning of common front-of-package nutrition-related claims on children's cereals and determine whether the claims would make them more willing to buy the cereals.
Parents viewed images of box fronts for children's cereals of below-average nutritional quality, as assessed by a validated nutrient profiling model. These boxes featured various nutrition-related claims including 'supports your child's immunity', 'whole grain', 'fibre', 'calcium and vitamin D' and 'organic'. Participants were provided possible meanings for these claims and asked to select any that applied with the option to write in additional meanings. They also indicated how the claim would affect their willingness to buy the product.
Online survey.
Parents with children between the ages of 2 and 11 years (n 306) recruited through an online panel.
The majority of parents misinterpreted the meaning of claims commonly used on children's cereals. They inferred that cereals with claims were more nutritious overall and might provide specific health-related benefits for their children; and these beliefs predicted greater willingness to buy the cereals.
These findings indicate that common front-of-package nutrition-related claims are potentially misleading, especially when placed on products with high levels of nutrients to limit (e.g. sugar, sodium) and low levels of other nutrients to encourage (e.g. fibre, protein). Additional regulation is needed to protect consumers in the USA.
研究父母对儿童麦片包装上前瞻性营养相关声明含义的看法,并确定这些声明是否会使他们更愿意购买这些麦片。
父母观看了经过验证的营养成分分析模型评估为营养质量低于平均水平的儿童麦片的盒面图像。这些盒子上有各种营养相关的声明,包括“支持孩子的免疫力”、“全谷物”、“纤维”、“钙和维生素 D”和“有机”。研究人员向参与者提供了这些声明的可能含义,并要求他们选择适用的含义,也可以选择填写其他含义。他们还表示声明将如何影响他们购买产品的意愿。
在线调查。
通过在线小组招募的 2 至 11 岁儿童的父母(n=306)。
大多数父母错误地理解了儿童麦片上常见声明的含义。他们推断,有声明的麦片总体上更有营养,可能为孩子提供特定的健康相关益处;而这些信念预测了他们购买麦片的更大意愿。
这些发现表明,常见的包装上前瞻性营养相关声明可能具有误导性,尤其是当它们被放在营养成分需要限制(例如糖、钠)水平高而需要鼓励(例如纤维、蛋白质)的其他营养成分水平低的产品上时。美国需要额外的监管来保护消费者。
