Smart Food Intake: development of a 2-hour recall methodology to measure context specific food intake and underlying food choice motives : overview of the project

An energising smoothie for breakfast, a convenient sandwich for lunch at work and a healthy and tasty curry for the family di nne r. During the day, we make different eating choices, depending on where we are and with whom we eat. To better collect insights in the wha t, where, when and why of food consumption, the food industry has expressed the need for more advanced data collection methods for food in take and its determinants. Current methods of monitoring food intake and food choice motives come with a range of drawbacks, inclu din g 1) a lack of linkage between food intake and its determinants, 2) a lack of inclusion of contextual variability, 3) high measureme nt errors, 4) time consuming data collection and 5) a high burden for the consumer and the researcher. Therefore, Smart Food Intake aimed to develop an innovative flexible methodology that enables to collect reliable food intake data and underlying food choice motives as important determinants of food intake. For that purpose, this project successfully developed a 2 hour recall ("snapshot") methodology. The methodology has proven to provide an adequate estimate of actual dietary intake and an acceptable estimate of habitual dietary intake via different sampling strat egi es. In addition, the measurement of food choice motives showed stable results in similar contexts and showed variability across different eati ng contexts, indicating the added value of measuring in context. The test retest reliability and the content validity of the food choice moti ves was satisfactory. The integrated methodology, combining assessment of food intake, the eating context and food choice motives, is positively evaluated. The SFI Traqq app has been developed to function as a tool to apply the integrated methodology in combination with survey software and is evaluated by users as easy and nice to use, and not too lengthy. The modular approach ensures the flexibility to easily adjust to specific research questions and enables to research 1) what people eat, 2) why they eat that, and 3) how this differs across eating contexts. These insights could help the food industry to stimulate m ore healthy and sustainable food consumption, by tailoring food formulations, communication and interventions towards various target groups a nd eating contexts better than before

Organics unpacked : The influence of packaging on the choice for organic fruits and vegetables

In many supermarkets throughout Europe, it has become common practice in the fruit and vegetable department to offer options in plastic packaging. Recent trends, however, move towards the removal of packaging. The current study examines whether offering fruit and vegetables without primary packaging increases the likelihood that consumers choose these products. This is especially relevant for organic fruit and vegetables, given that plastic may be perceived as contrary to the sustainable nature of these products. A first experiment, using a student sample and an immersive 3D virtual supermarket environment, shows that choice for organic fruit and vegetables indeed increases when organics are offered without packaging. A second experiment with the virtual supermarket generalizes these findings to a sample of supermarket patrons, additionally showing that unpacked fruit and vegetables are preferred over packed options overall, both for organic and non-organic products. We conclude that removing the primary packaging of organic fruit and vegetables appears to be a promising intervention in attempts to increase organic sales.</p

Using a Virtual Store As a Research Tool to Investigate Consumer In-store Behavior

This paper describes the use of a desktop virtual store to create virtual shopping environments to investigate in-store consumer behavior. A description of the protocol to build and run experiments, example results from an experiment concerning store layout, and important considerations when conducting virtual store experiments are presented

Consumer acceptance of personalised nutrition : The role of ambivalent feelings and eating context

Providing dietary suggestions based on an individual's nutritional needs may contribute to the prevention of non-communicable dietary related diseases. Consumer acceptance is crucial for the success of these personalised nutrition services. The current study aims to build on previous studies by exploring whether ambivalent feelings and contextual factors could help to further explain consumers' usage intentions regarding personalised nutrition services. An online administered survey was conducted in December 2016 with a final sample of 797 participants in the Netherlands. Different models were tested and compared by means of structural equation modelling. The final model indicated that the result of weighing personalisation benefits and privacy risks (called the risk-benefit calculus) is positively related to the intention to use personalised nutrition advice, suggesting a more positive intention when more benefits than risks are perceived. Additionally, the model suggests that more ambivalent feelings are related to a lower intention to use personalised nutrition advice. Finally, we found that the more the eating context is perceived as a barrier to use personalised nutrition advice, the more ambivalent feelings are perceived. In conclusion, the current study suggests the additional value of ambivalent feelings as an affective construct, and eating context as a possible barrier in predicting consumers' intention to use personalised nutrition advice. This implies that personalised nutrition services may need to address affective concerns and consider an individual's eating context.</p

Agro-Nutri Monitor 2022 - Achtergrondrapport : monitor prijsvorming voedingsmiddelen

Problemen in de prijsvorming of in de positie van boeren en tuinders in de keten kunnen ertoe leiden dat verduurzaming van de voedselproductie belemmerd wordt. Het ministerie van Landbouw, Natuur en Voedselkwaliteit (LNV) heeft de Autoriteit Consument & Markt (ACM) gevraagd hiernaar onderzoek te doen en daarbij een monitor te ontwikkelen. Dit rapport is een van de twee bijlagen bij het Hoofdrapport van de derde Agro-Nutri Monitor en wordt het Achtergrondrapport Agro-Nutri Monitor 2022 genoemd (kortweg Achtergrondrapport 2022). De andere bijlage is de consumentensegmenteringsstudie die ook in 2022 is uitgevoerd
