ABSTRACT
Insights into the use of health-related information on foods are important for planning studies about the effects of such information on the consumer's understanding, purchasing, and consumption of foods, and also support further food policy decisions. We tested the use of sales data for weighting consumers' exposure to health-related labeling information in the Slovenian food supply. Food labeling data were collected from 6342 pre-packed foods available in four different food stores in Slovenia. Consumers' exposure was calculated as the percentage of available food products with particular food information in the food category. In addition, 12-month sales data were used to calculate sales weighted exposure as a percentage of sold food products with certain food information in the food category. The consumer's in-store and sales-weighted exposure to nutrition claims was 37% and 45%, respectively. Exposure to health claims was much lower (13%, 11% when sales-weighted). Health claims were mainly found in the form of general non-specific claims or function claims, while children's development and reduction of disease risk claims were present on only 0.1% and 0.2% of the investigated foods, respectively. Sales data were found very useful for establishing a reliable estimation of consumers' exposure to information provided on food labels. The high penetration of health-related information on food labels indicates that careful regulation of this area is appropriate. Further studies should focus on assessing the nutritional quality of foods labeled with nutrition and health claims, and understanding the importance of such labeling techniques for consumers' food preferences and choices.

Mentions: After collecting the data, the retailers were asked to provide 12-month, country-wide sales volume data for each product included in the database (January 2011–December 2011). Ensuring proper data handling, we were able to obtain sales data from retailers covering over 62% of the national market. Sales data were available for 5104 foods in the above-mentioned database (80.5%) and this sample was used for further analyses (Table 2, Table 3 and Table 4 and Supplementary Tables S1, S3, and S4), except for comparisons between different store types (Figure 1, supplementary Table S2) which was done on the full sample of foods. One retailer (DIS) decided not to share its sales data due to its internal company policies. Unfortunately, such a policy is in place in all discounters in Slovenia. It should be noted that the sales data retailers provided referred to the complete national market and presented food product sales for the same year in which the above-mentioned food composition database was compiled. This was arranged on the condition that the results would not reveal the sales data of any particular retailer/product. The sales data were given in universal form and included the EAN barcode, description of the product, number of products sold per year and the quantity of food (kg/L) per packaging. The matching of foods between the databases was performed using EAN barcodes.

ABSTRACT
Insights into the use of health-related information on foods are important for planning studies about the effects of such information on the consumer's understanding, purchasing, and consumption of foods, and also support further food policy decisions. We tested the use of sales data for weighting consumers' exposure to health-related labeling information in the Slovenian food supply. Food labeling data were collected from 6342 pre-packed foods available in four different food stores in Slovenia. Consumers' exposure was calculated as the percentage of available food products with particular food information in the food category. In addition, 12-month sales data were used to calculate sales weighted exposure as a percentage of sold food products with certain food information in the food category. The consumer's in-store and sales-weighted exposure to nutrition claims was 37% and 45%, respectively. Exposure to health claims was much lower (13%, 11% when sales-weighted). Health claims were mainly found in the form of general non-specific claims or function claims, while children's development and reduction of disease risk claims were present on only 0.1% and 0.2% of the investigated foods, respectively. Sales data were found very useful for establishing a reliable estimation of consumers' exposure to information provided on food labels. The high penetration of health-related information on food labels indicates that careful regulation of this area is appropriate. Further studies should focus on assessing the nutritional quality of foods labeled with nutrition and health claims, and understanding the importance of such labeling techniques for consumers' food preferences and choices.
