We developed an implementation plan including several components to support implementation of the "Guidelines for Healthier Canteens" in Dutch secondary schools. This study evaluated the effect of this plan on changes in the school canteen and on food and drink purchases of students. In a 6 month quasi-experimental study, ten intervention schools (IS) received support implementing the guidelines, and ten control schools (CS) received only the guidelines.

The Netherlands Nutrition Centre has developed 'Guidelines for Healthier Canteens'. To facilitate their implementation, implementation tools were developed: stakeholders' questionnaires, the 'Canteen Scan' (an online tool to assess product availability/accessibility), a tailored advisory meeting/report, communication materials, establishment of an online community, newsletters, and a fact sheet with students' wishes/needs. In this quasi-experimental study, we investigated the effect of these tools in secondary schools on (a) factors perceived by stakeholders as affecting implementation; (b) the quality of implementation.

However, to date, these strategies are not often investigated in real-life settings, such as worksite cafeterias, or are only done so on a short-term basis.

Objective: The objective of this study is to examine the effects of a healthy worksite cafeteria ["worksite cafeteria 2.

The aim of this paper is to describe the intervention development and design of the evaluation of an intervention to make the purchase behavior of employees in the worksite cafeteria healthier. The developed intervention called "the worksite cafeteria 2.

This review evaluates the methodological quality of current front-of-pack labeling research and discusses future research challenges. Peer-reviewed articles were identified using a computerized search of the databases PubMed and Web of Science (ISI) from 1990 to February 2011; reference lists from key published articles were used as well. The quality of the 31 included studies was assessed.

Objective: Nutritional interventions to decrease energy intake, aimed at portion sizes and front-of-package labelling, are effective only if people do not compensate for their reduced energy intake. Since several observational studies indicate that these interventions could prompt compensation behaviour, it is important to assess underlying beliefs. Therefore, the purpose of the two studies reported here was to develop a Diet-related Compensatory Health Beliefs Scale (Diet-CHBS).

By both increasing the availability of healthy foods and labeling these products with the Choices logo, caterers may facilitate employees to make a healthier choice in their worksite cafeterias. The aim of this study was to explore which attributes influence the implementation of the Choices logo in worksite cafeterias in the Netherlands. Questionnaires were completed by catering managers of 316 cafeterias of two large caterers in the Netherlands (response rate 49.

This study investigated the effectiveness of labeling foods with the Choices nutrition logo on influencing cafeteria menu selection and the behavioral determinants of menu choices in work site cafeterias in the Netherlands. A cluster randomized controlled trial was conducted. Intervention cafeterias (n=13), where the Choices logo was used to promote healthier eating for a 3-week period, were compared with control cafeterias (n=12), which offered the same menu without the logo.

Background: In addition to helping consumers make healthier food choices, front-of-pack nutrition labels could encourage companies to reformulate existing products and develop new ones with a healthier product composition. This is the largest study to date to investigate the effect of a nutrition logo on the development of healthier products by food manufacturers.

Methods: A total of 47 food manufacturers joining the Choices Foundation in the Netherlands (response: 39.

Objective: A front-of-pack nutrition logo on products with relatively favourable product compositions might help consumers to make more healthful choices. Studies investigating actual nutrition label use in point-of-purchase settings are scarce. The present study investigates the use of the 'Choices' nutrition logo in Dutch supermarkets.

This study aimed to perform a quantitative and qualitative process evaluation of the introduction of the Choices logo, a front-of-pack nutrition logo on products with a favorable product composition, adopted by many food producers, retail and food service organizations, conditionally endorsed by the Dutch government, validated by scientists, and in the process of international dissemination. An online questionnaire was sent to adult consumers 4 months after the introduction of the logo (n = 1,032) and 1 year later (n = 1,127). Additionally, seven consumer focus groups (n = 41) were conducted to provide more insight into the questionnaire responses.
