“…The Swedish Keyhole (Larsson et al, 1999) and the Smart Choices logo (Lupton et al, 2010) are examples of such schemes which evaluate both positive and risk nutrients to establish whether the product is deemed to be healthy in relation to other foods in the same category.…”

“…In addition to BOP nutrition labelling, simpler front-of-pack (FOP) labels can be used to show the percentage of Guideline Daily Amounts (GDA) for several key nutrients or to indicate the general healthfulness of food products (9,16,17) . Examples of the latter approach are the Green Keyhole logo that is used in Sweden (18) and the Pick the Tick logo that is used in New Zealand (19) . Besides nutritional information on food packages, however, there are several other ways to convey product health information, such as attaching information to shelves (20) , using posters that are placed next to or over the product rack (21) or audio messages that are played in supermarkets and grocery stores (22) .…”

Objective: Information about healthy and unhealthy nutrients is increasingly conveyed at the point of purchase. Many studies have investigated the effects of product health information on attitudes and intentions, but the empirical evidence becomes sketchier when the focus of research is actual purchase behaviour. The present paper provides an overview of empirical evidence on the effectiveness of product health information for food products at the point of purchase. Design: A systematic literature review was conducted. Setting: Only studies were included that assessed the effect of product health information at the point of purchase on actual purchase behaviour, using data provided by stores' sales records or obtained by investigating customer receipts as the primary outcome measure. Subjects: The included studies' target group comprised supermarket clientele. Results: Several studies found no significant effects of product health information on actual purchase behaviour. Interventions were more likely to be effective when they lasted for a longer time, when they included additional intervention components, and when they targeted the absence of unhealthy nutrients instead of or in addition to the presence of healthy nutrients. Conclusions: No strong evidence for the effectiveness of product health information was found. The effect of intervention duration, additional promotional activities and targeting of healthy v. unhealthy nutrients should be closely examined in future studies.

“…Front-of-pack nutrition icons on products with relatively favourable product compositions have been introduced in some countries to help consumers make healthier choices (4) . For example, the Green Keyhole has been in use in Sweden (5) and Pick the Tick programme in Australia (6) since the late 1980s. More recently, the Choices health logo has been introduced in the Netherlands (4) and the Smart Choices programme in the USA (7) .…”

“…These front-of-pack labelling formats differ not only by appearance but also by regulations on which the right to use a logo on products is based and by authorities responsible for the system in each country. For example, in Sweden, the Green Keyhole logo was introduced by the Swedish National Food Administration (5) , whereas in Australia, the Heart Foundation created the Pick the Tick logo based on national criteria for salt, energy, fibre and added sugar (6) . In the USA, in turn, the criteria are based on the 2005 Dietary Guidelines covering nineteen product categories and six nutrients and, in some cases, energy (7) .…”

Objective: To study the awareness of the Heart Symbol in different age and educational groups, and changes in the awareness over a 9-year period. In addition, the reported use of products with the symbol was examined. Design: A series of annual cross-sectional postal surveys on Health Behaviour and Health among the Finnish Adult Population. Setting: A random sample (n 5000 per annum) from the Finnish population aged 15-64 years, drawn from the National Population Register, received a questionnaire. Subjects: Men and women (n 29 378) participating in the surveys in [2000][2001][2002][2003][2004][2005][2006][2007][2008][2009]. Results: At the early 2000s, 48 % of men and 73 % of women reported to be familiar with the symbol. The corresponding rates were 66 % for men and 91 % for women in 2009. The reported use of products with the symbol increased from 29 % to 52 % in men and from 40 % to 72 % in women. In men, the awareness did not vary by age, whereas older women (45-64 years) were less likely to be aware of the symbol compared with younger women (25-34 years). Men and women with the highest education were best aware of the symbol and more likely to use the products in the early 2000s. The educational differences diminished or disappeared during the study period. Conclusions: The majority of Finnish adults are familiar with the Heart Symbol, and the reported use of such products increased in all age and educational groups, especially among the less educated. The symbol may work as an effective measure to diminish nutrition-related health inequalities.
