Front of pack food labelling is becoming increasingly common on packaged foods in the UK. The UK government has recommended that the front of pack labelling scheme includes traffic light labelling – so called because of the distinctive red, amber and green colours. Traffic light labelling shows the levels of total fat, saturated fat, sugar and salt in food products in an 'at a glance' format, in order to help shoppers in buying healthier foods. We know, however, that front of pack labels currently have little influence on what shoppers' decide to buy. This study investigates whether an interactive web application (the intervention), designed to change behaviour though 'behaviour change theory', leads to healthier food purchases. The application offers, for example, interactive information on traffic light labelling, personalised feedback on each participants shopping behaviour and strategies for using front of pack labels to make healthier food purchases. The aim of the study is to measure important aspects of the study design - such as how quickly shoppers can be recruited for the study. This will help to design a bigger study of whether the intervention works at a later date.

Electronic loyalty card purchase data is collected for all foods purchased by participants during the study period, and in the six months before the study starts. This store card data is used to measure whether the intervention has influenced food purchases. Participants are randomly allocated into two groups: –a control group and an intervention group. The intervention group is given access to the intervention (delivered by email) for 6 weeks. Both the control and intervention groups are asked to fill in three questionnaires during the study: at enrolment, three weeks into the study and at the end of the study. The questionnaire is designed to measure psychosocial variables associated with use of front of pack food labels. After the study is completed, phone interviews are conducted with some of the participants to find out what did and didn't work with the study.


UK residents aged 18 or older, a regular user of the participating supermarket loyalty card, the primary shopper for the household, frequent purchasers of ready meals and/or pizzas, and are not planning to leave the UK for a period of three weeks or more during the study period.
