Perceptions of food risk management among key stakeholders : Results from a cross-European study

In designing and implementing appropriate food risk management strategies, it is important to examine how key stakeholders perceive both the practice and effectiveness of food risk management. The objective of this study is to identify similarities and differences in perceptions of, and attitudes to, food risk management practices held by consumers and experts with an interest in food safety. Focus groups were conducted in five European countries chosen for their (hypothesised) cultural differences in attitudes towards risk: Denmark, Germany, Greece, Slovenia and the UK. Content analysis was carried out on the resulting texts and (sub) categories were identified within the analysis framework to facilitate the capture of emerging themes. Five key themes were identified as common to the perceptions of both consumers and experts, although these are not represented in the same way by both groups. These key themes are: (1) efforts made by the responsible authorities to manage food risks; (2) responsibility for prevention and management of food risks; (3) how priorities are established within regulatory systems; (4) scientific progress and its implications for food risk management; and (5) media attention and food safety incidents. Although some similarities emerged between the groups, differences were also identified. For example, experts appeared to be highly negative about media influences, whereas consumers appeared more indifferent about media influences and motives. These different perspectives need to be addressed in order to reduce the perceptual distance between key stakeholders, and in particular, to enhance consumer confidence in the food risk management system. Based on the study findings, recommendations for food risk management policies are outlined.

Consumer preferences for front-of-pack calories labelling

Objective In light of the emerging obesity pandemic, front-of-pack calories labels may be an important tool to assist consumers in making informed healthier food choices. However, there is little prior research to guide key decisions on whether caloric content should be expressed in absolute terms or relative to recommended daily intake, whether it should be expressed in per serving or per 100 g and whether the information should be further brought alive for consumers in terms of what the extra calorie intake implies in relation to activity levels. The present study aimed at providing more insight into consumers’ appreciation of front-of-pack labelling of caloric content of food products and their specific preferences for alternative execution formats for such information in Europe. Design For this purpose, eight executions of front-of-pack calorie flags were designed and their appeal and information value were extensively discussed with consumers through qualitative research in four different countries (Germany, The Netherlands, France and the UK). Results The results show that calories are well-understood and that participants were generally positive about front-of-pack flags, particularly when flags are uniform across products. The most liked flags are the simpler flags depicting only the number of calories per serving or per 100 g, while more complex flags including references to daily needs or exercise and the flag including a phrase referring to balanced lifestyle were least preferred. Some relevant differences between countries were observed. Although participants seem to be familiar with the notion of calories, they do not seem to fully understand how to apply them. Conclusion From the results, managerial implications for the design and implementation of front-of-pack calorie labelling as well as important directions for future research are discussed.

Consumer-oriented functional food development: how well do functional disciplines reflect the ‘voice of the consumer’?

Food innovation can have its source in either superior understanding of consumer demand (pull) or in superiority at the supply side (science and technology push). However, in either case market success depends on the degree to which the new product reflects unmet consumer needs. The present study provides a framework, which allows to obtain relevant consumer and expert input in the early stages of functional food development. By systematically generating and rigorously screening a large set of functional food concepts both inside (functional food experts) and outside (consumers) the company, the framework prevents that high potential opportunities are overlooked. This in turn provides a platform for product developers to discuss and decide upon which opportunities to pursue. The illustration of the framework shows the extent to which expert judgements are an accurate reflection of consumer demand.

Healthy snacks at the checkout counter: A lab and field study on the impact of shelf arrangement and assortment structure on consumer choices

BackgroundThe essence of nudging is to adapt the environment in which consumers make decisions to help them make better choices, without forcing certain outcomes upon them. To determine how consumers can effectively be guided to select healthier snacks, we examine the effect of manipulating the assortment structure and shelf layout of an impulse display including both healthy and unhealthy snacks near the checkout counter of a canteen.MethodsBoth a lab and field study applied a two-factor experimental design manipulating snack offerings both in an on-screen choice environment and a natural environment (hospital staff restaurant). Shelf arrangement (i.e. accessibility) was altered by putting healthy snacks at higher shelves versus lower shelves. Assortment structure (i.e. availability) was altered by offering an assortment that either included 25% or 75% healthy snacks. Participants in the lab study (n = 158) made a choice from a shelf display. A brief survey following snack selection asked participants to evaluate the assortment and their choice. The field experiment took place in a hospital canteen. Daily sales data were collected for a period of four weeks. On completion of the field study, employees (n = 92) filled out a questionnaire about all four displays and rated their attractiveness, healthiness and perceived freedom of choice.ResultsThe lab study showed a higher probability of healthy snack choice when 75% of the assortment consisted of healthy snacks compared to conditions with 25% healthy snack assortments, even though choices were not rated less satisfying or more restrictive. Regarding shelf display location of healthy snacks, no significant differences were observed. There was also no significant shelf arrangement by assortment structure interactive effect. The field study replicated these findings, in that this assortment structure led to higher sales of healthy snacks. Sales of unhealthy and total snacks were not impacted by manipulations (no main or interaction effects). Employees preferred shelf displays including a larger healthy snack assortment located at top shelves. Employees also felt more freedom in choice when healthy snacks were displayed at top shelves compared to lower shelves.ConclusionsOverall, results suggest that increasing the prominence of healthy snacks by enlarging their availability, while permitting access to unhealthy snacks, is a promising strategy to promote sales. These results point to the importance of nudging strategies to encourage healthier snack patterns.

The Growing Role of Front-of-Pack Nutrition Profile Labeling: A Consumer Perspective on Key Issues and Controversies

Nutrition-related diseases, such as some cancers, heart diseases, and obesity, belong to the most challenging health concerns of our time. Communicating intuitive and simple nutrition information by means of front-of-pack (FOP) nutrition profile signpost labeling is increasingly seen as an essential tool in efforts to combat unhealthy food choices and improve public health. Consequently, much attention in policy and research is given to nutrient profiling methods and the determination of optimal nutrition criteria. Although consumer research on nutrition signpost labeling is now gradually appearing in the literature, the value and meaning of these labeling systems for consumers have received less attention. In the current debate a concise overview is lacking of the consumer perspective, including relevant psychological phenomena, in relation to much debated controversies surrounding these labels and their further development, such as the most effective type of signpost labeling system and varying stakeholder interests. Therefore, this paper aims to critically review the literature in the consumer domain of FOP nutrition labeling in order to illustrate the strengths and weaknesses of this form of nutrition education from a consumer perspective.

Consumer perceptions of the effectiveness of food risk management practices : A cross-cultural study

Abstract Consumer perceptions of food hazards and how the associated risks are managed are likely to be an important determinant of consumer confidence in food safety. While there is a body of research that examines public perceptions of various types of food hazards, less attention has been directed to understanding how the public perceives food risk management practices. Utilizing elements of the repertory grid approach in focus group discussions, this research explored public attitudes regarding the effectiveness of current food risk management practices in four European countries (Denmark, Germany, Greece and the UK). While the issue of food safety did not emerge as a key factor in everyday food choice, participants were concerned about health aspects of food. There were three main factors that participants considered to be evidence of ‘good’ food risk management: the existence of identifiable control systems that respond quickly to contain a risk, the instigation of preventive measures and the availability of information that offers individuals the ability to exercise informed choice. These evaluations were similar in each of the countries under consideration and were linked to ideas regarding the controllability of risks and to questions of who is responsible for managing the risks.

Serving Bowl Selection Biases the Amount of Food Served.

OBJECTIVE To determine how common serving bowls containing food for multiple persons influence serving behavior and consumption and whether they do so independently of satiation and food evaluation. METHODS In this between-subjects experiment, 68 participants were randomly assigned to either a group serving pasta from a large-sized bowl (6.9-L capacity) or a medium-sized bowl (3.8-L capacity). RESULTS Analysis of covariance showed that when given a large-sized bowl, diners served 77% more pasta (364.0 vs. 205.5 g; P < .01) and felt more satiated (P = .03) compared with diners given a medium-sized bowl, even though the food was not rated tastier or otherwise notable (all P > .32). CONCLUSIONS AND IMPLICATIONS In contrast to those in studies involving larger-sized plates and spoons, people serving from larger bowls felt more satiated. These findings again highlight the role that external cues play in food consumption and show the importance of considering serving bowl size in nutrition education.

Food risk management quality: Consumer evaluations of past and emerging food safety incidents

In European countries, there has been growing consumer distrust regarding the motives of food safety regulators and other actors in the food chain, partly as a result of recent food safety incidents. If consumer confidence in food safety is to be improved, a systematic understanding of what consumers perceive to be best practice in risk management is crucial. Previous qualitative and quantitative research has revealed underlying factors determining consumer perceptions of food risk management quality. The aim of the current case studies is to provide ‘proof of principles’ of these different factors against historic and emerging food safety incidents. Participants in four countries were questioned about country specific case studies, guided by the earlier findings regarding factors that determine perceived good practice in food risk management. In each country, two food safety incidents were selected. Semi-structured interviews with at least 25 participants per case study were conducted in Germany (BSE; nematode worms in fish), Greece (mould in Greek yogurt/carcinogenic honey crisis; avian influenza), Norway (E. coli in meat; contaminants in Norwegian salmon) and the UK (BSE; contaminants in Scottish salmon). The results generally confirm the importance of the previously identified factors, which help to explain relative perceptions of well and poorly managed incidents. Differences and similarities across countries and cases are detailed, and implications for future efforts to communicate about risk management are drawn.

Dinner rituals that correlate with child and adult BMI

What predicts whether a child will be at risk for obesity? Whereas past research has focused on foods, eating habits, feeding styles, and family meal patterns, this study departs from a food‐centric approach to examine how various dinner rituals might influence the BMIs of children and adults.

Knowledge, perceptions and preferences of elderly regarding protein-enriched functional food ☆

Promoting protein consumption in the elderly population may contribute to improving the quality of their later years in life. Our study aimed to explore knowledge, perceptions and preferences of elderly consumers regarding protein-enriched food. We conducted three focus groups with independently living (ID) elderly (N = 24, Mage = 67 years) and three with elderly living in a residential home (RH) (N = 18, Mage = 83 years). Both the ID and RH elderly were predominantly sceptical about functional food in general. Confusion, distrust and a perceived lack of personal relevance were main perceived barriers to purchasing and consuming these products, although a majority of the participants did report occasionally consuming at least one type of functional food. For the ID elderly, medical advice was an important facilitator that could overcome barriers to purchasing and consuming protein-enriched food, indicating the importance of personal relevance for this group. For the RH elderly, in contrast, sensory appeal of protein-enriched foods was a facilitator. Carrier preferences were similar for the two groups; the elderly preferred protein-enriched foods based on healthy products that they consumed frequently. Future studies should explore ways to deal with the confusion and distrust regarding functional food within the heterogeneous population of elderly.Promoting protein consumption in the elderly population may contribute to improving the quality of their later years in life.
