Abstract [en]

This field experiment explored whether and to what extent claims about expert recommendations (i.e., those of the chef) and recommendations from other restaurant guests influenced customers' food choices in a restaurant. The menu in the study consisted entirely of vegetarian dishes, two of which were selected to be emphasised either as “Chef's choice” or as “Guests' choice” on the menu, thereby providing expert-based and social-based cues suggesting one of the dishes at different study time points. The selected dishes were a vegetarian version of a conventional Swedish meat dish (a plant-based patty) and a nonconventional dish (lentils with “zero-waste” pesto). Over four weeks, the restaurant's sales data were collected, and customers were invited to participate in a voluntary survey. This survey gathered information regarding sociodemographic characteristics and more details about the dish selection, including subjective ratings of dish liking and overall meal satisfaction. A total of 1540 dishes were sold, and 524 customers participated in the survey. The plant-based patty was the most popular choice across all weeks, and the “Chef's choice” had no additive effect, suggesting its high stability in popularity. Labelling a less popular dish (lentils with “zero-waste” pesto) with “Chef's choice” had a positive impact on its selection, while labelling it with “Guests' choice” made no difference. These results suggest that in the absence of meat options, some customers appear to transfer the concept of a meat-centric dish to a similar vegetarian dish (in this case, a plant-based patty), whereas a less popular dish with no resemblance to a conventional meat dish can become more popular when recommended by a presumable expert on the matter. However, further research is necessary to ascertain the efficacy of this effect in diverse restaurant contexts, based on designs with better possibilities to establish causality.

Abstract [en]

The contemporary food system is no longer just a matter of nourishment; it has become a mirror reflecting the ecological, social and psychological tensions of our time. The manner in which we produce and consume food is intricately linked to a number of the most pressing challenges facing society, including climate change and rising health issues. The significance of dietary choices is becoming increasingly evident, with the heart of the matter being why people eat what they do and how people's food choices can be changed. This dissertation explores the role of hedonic and social factors in shaping the adoption of sustainable food choices by exploring three themes: Products, Restaurants and Everyday life. Each theme is explored through a combination of different methodological approaches, including consumer sensory evaluation, field experimentation and a randomised controlled trial enriched with social network analysis.The findings collectively highlight the need for multi-level strategies, which must integrate psychological, social and situational factors in order to be effective. While consumer preferences for the sensory attributes of plant-based meat alternatives differ depending on consumer psychographics (i.e. meat attachment), a preference for products that replicate the sensory experience of conventional meat remains dominant. Beyond sensory drivers, meat also carries symbolic meanings associated with tradition, strength and status. These cultural associations reinforce a 'meat-centric’ gastronomic logic, even in vegetarian formats. However, consumer choice can be influenced when a gastronomic authority (i.e. a chef) recommends a less-popular, non-meat-mimicking vegetarian dish. The same cannot be said for social cues (i.e. cues from other guests), which do not appear to influence consumer choice. It is possible that the fragmentary information – whether factual or social – provided to participants within the studies of this dissertation was insufficiently potent to induce continuous and systematic dietary changes in everyday life, suggesting that influence may stem more from particularly influential individuals than from generic others. All in all, this dissertation provides insights into segmentation strategies that may be considered for future product development within the industry, for use within the food-service sector and for methodological application to future research.
