Health claims on food products, which aim at informing the public about the health benefits of the product, represent one type of nutrition communication; the use of these is regulated by the European Union. This paper provides an overview of the research on health claims, including consumers' perceptions of such claims and their intention to buy products that carry health-related claims. This is followed by a discussion on the results from some recent studies investigating public perceptions and willingness to use products with health claims. In these studies, claims are presented in the form of messages of different lengths, types, framing, with and without qualifying words and symbols. They also investigate how perceptions and intentions are affected by individual needs and product characteristics. Results show that adding health claims to products does increase their perceived healthiness. Claim structure was found to make a difference to perceptions, but its influence depended on the level of relevance, familiarity and individuals' need for information. Further, the type of health benefit proposed and the base product used also affected perceptions of healthiness. The paper concludes that while healthiness perceptions relating to products with health claims may vary between men and women, old and young and between countries, the main factor influencing perceived healthiness and intention to buy a product with health claim is personal relevance.
食品的健康声称旨在向公众宣传产品的健康益处,这是一种营养传播方式;这些声称的使用受到欧盟的监管。本文概述了有关健康声称的研究,包括消费者对这些声称的看法以及他们购买带有与健康相关声称的产品的意愿。接着讨论了一些最近研究的结果,这些研究调查了公众对健康声称的看法和使用带有健康声称的产品的意愿。在这些研究中,声称以不同长度、类型、框架的信息形式呈现,有或没有限定词和符号。研究还调查了个体需求和产品特征如何影响看法和意愿。结果表明,在产品上添加健康声称确实会增加其被感知的健康度。声称结构对看法有影响,但影响取决于相关性、熟悉度和个体对信息的需求水平。此外,提出的健康效益类型和使用的基础产品也会影响对健康度的看法。本文得出结论,尽管与具有健康声称的产品相关的健康度看法可能因性别、年龄和国家而异,但影响感知健康度和购买具有健康声称的产品意愿的主要因素是个人相关性。
