Applying partial least squares to model genetically modified food purchase intentions in southern Spain consumers

Consumers’ potential reactions towards genetically modified (GM) foods influence their commercial feasibility and determine the decisions of economic agents. This paper studies the underlying factors involved in determining consumers’ choice behaviour towards GM foods in order to develop an integrated analytical framework. Reliable information about consumers’ behaviour towards GM foods should lead to the design of political strategies intended to make citizens feel safe in their purchasing choices. In addition, there is an analysis of behavioural differences due to consumers’ objective knowledge levels. The research was performed in southern Spain using variance-based structural equation modelling, namely the Partial Least Squares (PLS) regression technique. The results support those arguments that connect consumers’ behavioural intentions, attitudes and different factors involved in determining consumer choice, because attitudes towards GM foods link consumer purchasing intentions to the perceived benefits and risks posed by GM foods. Furthermore, there are some insights into the moderating role played by the consumers’ level of knowledge in their purchase intentions to GM food.     

A consumer segmentation of nutrition information use and its relation to food consumption behaviour

Consumers need information such as nutrition tables to assess the nutritional value of a food product. Although a broad range of studies has examined consumers’ attention, perception and use of nutrition tables, relatively little is known about what types of consumers use what kind of nutrition information. Therefore, using data from the Swiss Food Panel, we conducted a cluster analysis of nutrition information usage and health and nutrition interest to determine whether consumers could be segmented into specific groups. We identified four segments, which we labelled Official Information Users, Internet Users, Moderate Users and Uninterested. We then determined the segments’ demographics, food frequencies and perception of food. Based on our findings, we provide suggestions for targeted interventions that stimulate healthy food choices among these four segments. Our findings imply that nutrition education or the improvement of nutrition labels is unlikely tostimulate nutrition information usage among all consumer types; some consumers may rather benefit more from environmental cues that prime healthy food choices.     

Change is good!? Analyzing the relationship between attention and nutrition facts panel modifications

Many consumers do not pay attention to nutrition information, a necessity to make healthy food choices. We measure attention to a Nutrition Facts Panel (NFP) currently used in the U.S. and to a modified NFP that emphasizes key information, using eye-tracking in a between-subjects experiment. We test for differences between attention to the current and modified NFP but also for differences across food items. We find asymmetric effects, depending on the product. For healthier items more attention is paid to the modified NFP than to the current NFP. For less healthy items less attention is paid to the modified NFP than to the current NFP. Results suggest that a single modified design may not be uniformly effective.     

Health information and consumer learning in the bottled water market

This paper examines the impact of health information in different media outlets on bottled water consumption through consumer learning. We develop a random coefficient discrete choice model with Bayesian learning process to capture consumers’ learning of health information and changes in their beverage choices over time. Consumers are assumed to have initial prior beliefs about the health effect of different beverages and to update their beliefs using health information received from different media types. Empirical results show that consumers’ perceived quality of bottled water kept increasing during our sample period, and this learning process accounted for 24.44% of the industry’s revenue, which is about 4.8 billion dollars per year. Comparing the effectiveness of different media outlets, we find that the sales impact of traditional media (TV and radio) is greater than online sources. Our findings highlight the contribution of health information to the bottled water industry and provide policy makers with a new direction to reduce high-calorie food consumption and improve public health.     

The impact of expiration dates labels on hedonic markets for perishable products

This study draws inferences from a pre-registered field experiment to investigate how expiration dates impact consumer preferences for food products with different ages. Based on a power analysis, we recruited 373 adult participants for the experiment. The results demonstrate that expiration dates largely influenced the perceived freshness of a food product as they seem to indicate a quality standard. When no explicit expiration date was present, consumers believed that the product’s quality decreased monotonically as time passed. However, in the presence of an expiration-date label, consumers initially perceived the product as more acceptable, but then that perception changed quickly after the date of expiration to levels more consistent with what they would perceive if the expiration date was not present. These results support policies that label expiration dates for consumers, as these labels benefit consumers, producers, and the public, especially for times prior to the expiration date. These results also suggest that it is important to craft policy and market strategies for products that are past the expiration date, but are still safe to consume. Policies that set the expiration dates to the time where the taste quality begins to worsen would likely benefit both consumers and producers, while policies that set the expiration dates to the time where the food is no longer safe probably improve the public outcomes as it minimizes food waste.     

Impact of health-related claims on the perception of other product attributes

New EU legislation (EU Regulation 1924/2006) will allow a number of nutrition and health claims in food products. The objective of this research was to study how health claims affect consumers’ perception of other product attributes. A survey with a total of 4612 respondents from the Nordic countries explored consumers’ perceptions of attractiveness, healthiness, naturalness, tastiness and ability to reduce risk of disease by comparing ratings of products with and without health claims. Used claims varied in their benefit, active ingredient, claim structure and framing. The results showed that health claims had a moderate but mostly negative impact on the perception of other product attributes; the most significant impact was decrease in perceived naturalness. Consumers could also interpret the benefits in claims as intended. The wording of the claim had only small impact on the perception of the products, whereas earlier market presence of the ingredient had a large impact: differences among the Nordic countries reflected the previous exposure to health claims. The findings from this study suggest that consumers do not imply other health benefits from health claims and the health claim per se is not likely to cause any unrealistic positive inferences in perceived product quality.     

Traffic lights and food choice: A choice experiment examining the relationship between nutritional food labels and price

In this paper we investigate how consumers respond to the UK nutritional food label Traffic Light System (TLS). Employing a choice experiment (CE) we find that consumers appear to behave in a manner consistent with our expectations regarding the impact of the TLS. We identify a strong preference on the part of respondents to avoid a basket of goods containing a mix of foods with any “Red” lights. In addition, we find that consumers have a hierarchy of importance in terms of perception of the various nutrients examined and there are clear behavioural differences associated with particular socio-economic characteristics confirming early research on the use of nutrition labels. Overall our results indicate significant heterogeneity in the attitudes and responses of consumers to the TLS nutritional food labels within and across socio-economic strata.     

An experiment on cash and in-kind transfers with application to food assistance programs

The impact of providing food assistance in kind (via food, stamps, or restricted debit cards) vs. cash has long been a subject of debate. Prior efforts to causally identify the effects of the two types of transfers have been hindered by concerns over non-random selection into assistance programs, misreporting of program benefits, and identification of inframarginal households who, theoretically, should treat cash and in-kind transfers identically. This paper reports the results of an economic experiment designed to cleanly test some conceptual issues associated with in-kind vs. cash giving in a lunchroom meal setting. Given current debates about the healthiness of food assistance recipients’ diets, we also consider the impacts of placing restrictions on in-kind transfers that either prohibit soda purchases with the transfer or require the transfer be spent on fruits and vegetables. Overall, we find that, as theory predicts, in-kind transfers have the same effect on food expenditures as an unrestricted cash transfer for inframarginal consumers, and for extramarginal consumers, food expenditures are higher for in-kind than cash transfers. Participants also respond to the fruit and vegetable restriction as theory would predict. However, in contrast to the theoretical prediction, the soda restriction reduces soda expenditures for more than half the inframarginal consumers.     

European consumer preferences for beef with nutrition and health claims: A multi-country investigation using discrete choice experiments

The European Union (EU) nutrition labelling policy aims to facilitate consumers’ food choice, stimulate innovation and facilitate the circulation of foods bearing claims across countries. However, the beef industry has not fully taken advantage of utilizing nutrition and health claims based on the EU nutrition labelling policy to differentiate beef products in the market. This study investigates consumer preferences for nutrition and health claims on lean beef steak. Two choice experiments were conducted among 2400 beef consumers in four EU countries (Belgium, France, the Netherlands, United and United Kingdom). Multinomial logit and error component models were estimated. Our results generally suggest that consumer valuation of nutritional and health claims varies across countries. In Belgium, the Netherlands and France, nutrition and health claims on saturated fat yielded higher utilities than claims on protein and/or iron, while the opposite was found among consumers in the UK. The results imply that marketing opportunities related to nutrition and health claims on beef are promising, but that different nutritional marketing strategies are necessary within different countries.     

Assessing consumer willingness to pay for Arctic food products

The food industry increasingly seeks to differentiate food products based on sustainability assurances, the use of traditional or ‘authentic’ production methods, a unique origin, or an association with a distinct cultural identity, often relying on certification to enhance the credibility of a quality claim. The natural conditions of the Arctic circumpolar region, its pristine environment, and the relational tie to Indigenous cultures in many circumpolar Arctic nations, distinguish Arctic foods from other commercially available foods, however, little is known about how consumers respond to foods from the Arctic. This paper examines consumers’ perceptions of and willingness to pay (WTP) for foods originating from the Canadian Arctic, and their receptivity to certification for sustainability, authenticity, and origin in the presence of multiple credence attributes. Data from an online survey of 1342 Canadian consumers show that preferences for Arctic foods are driven by the unique geographic origin and a connection with Indigenous cultures and traditions, as well as a desire to improve social and economic conditions in northern Canada. A discrete choice experiment featuring Arctic char elicits consumers’ WTP for attributes related to origin, certification, wild vs farmed fish, and Indigenous vs non-Indigenous fishers. Random parameters logit and generalized mixed logit models allow for both preference and scale heterogeneity. The analysis informs strategies to promote the Arctic food system, both from a Canadian regional economic development context and across the broader Arctic circumpolar region. Limitations imposed by the current seafood labelling regulatory environment in Canada are noted.     

Consumers’ valuation for food traceability in China: Does trust matter?

Food safety is a very important topic in China. We investigate Chinese consumers’ preferences and willingness to pay (WTP) for food traceability using a choice experiment. Given that consumers’ trust in the food system may affect their preferences and WTP, we also assess the interaction between consumers’ trust in government’s supervision of food safety and food labels and consumers’ preferences for traceable food products. Using data collected from a choice experiment on Fuji apples in a face-to-face survey in six Chinese cities, the results show that (i) consumers are willing to pay for traceable food but their valuations can differ upon the degree of their trust in government’s supervision of food safety and food labels; (ii) consumers are willing to pay for traceability with strong evidence of preference heterogeneity; (iii) government is not the most trusted safety inspection and certificate authority as found in prior studies using animal food products in China.     

The rising disparity in the price of healthful foods: 2004–2008

Nutrient-dense foods that are associated with better health outcomes tend to cost more per kilocalorie (kcal) than do refined grains, sweets and fats. The price disparity between healthful and less healthful foods appears to be growing.This study demonstrates a new method for linking longitudinal retail price data with objective, nutrient-based ratings of the nutritional quality of foods and beverages. Retail prices for 378 foods and beverages were obtained from major supermarket chains in the Seattle, WA for 2004–2008. Nutritional quality was based on energy density (kcal/g) and two measures of nutrient density, calculated using the Naturally Nutrient Rich (NNR) score and the Nutrient Rich Foods index (NRF_9.3). Food prices were expressed as $/100 g edible portion and as $/1000 kcal. Foods were stratified by quintiles of energy and nutrient density for analyses.Both measures of nutrient density were negatively associated with energy density and positively associated with cost per 1000 kcal. The mean cost of foods in the top quintile of nutrient density was $27.20/1000 kcal and the 4-year price increase was 29.2%. Foods in the bottom quintile cost a mean of $3.32/1000 kcal and the 4-year price increase was 16.1%.There is a growing price disparity between nutrient-dense foods and less nutritious options. Cost may pose a barrier to the adoption of healthier diets and so limit the impact of dietary guidance. Nutrient profiling methods provide objective criteria for tracking retail prices of foods in relation to their nutritional quality and for guiding food and nutrition policy.     

Exploring dietary guidelines based on ecological and nutritional values: A comparison of six dietary patterns

The objective of this study was to explore the synergies between nutritionally healthy and ecologically sustainable diets. The aim was to explore the possibilities for future integrated dietary guidelines that support consumers to make informed dietary choices based on both ecological and nutritional values. We developed a score system for health and sustainability. Subsequently, we tested six different diets: current average Dutch, official ’recommended’ Dutch, semi-vegetarian, vegetarian, vegan and Mediterranean. For the sustainability rating, we used the Life Cycle Assessment, measuring the impacts on greenhouse gas emissions (GHG) and land use (LU). For the health rating, we used ten nutritional indicators. By comparing the overall scores we found that the consumption of meat, dairy products, extras, such as snacks, sweets, pastries, and beverages, in that order, are largely responsible for low sustainability scores. Simultaneously, these food groups contribute to low health scores. We developed a matrix that illustrates that the health and sustainability scores of all six diets go largely hand in hand. Fig. 1 provides a visualisation of the position of the six diets in the full health and sustainability spectrum. This matrix with scores can be considered a first step in the development of a tool to measure both sustainability and health issues of specific food patterns. In selecting the diets, we examined two directions: health focus diets and the animal protein reduction diets. The Mediterranean diet is generally the health focus option with a high sustainability score. We conclude that guidelines oriented in between the two directions (i.e., semi- and pesco-vegetarian) are the option with the optimal synergy between health and sustainability.     

Indigenous Shawi communities and national food security support: Right direction,but not enough

Food insecurity is a major challenge facing Peru’s Indigenous Shawi communities, who receive food support through national level programs. There is limited research, however, on how national food and social programming support is perceived, received and used among Indigenous communities. We address this research gap by characterizing the preferred diet and coping mechanisms among Shawi Indigenous households, and investigating community perspectives on the national food program and national social supports. We used a mixed methods approach, including a quantitative survey among eleven Shawi communities in the Peruvian Amazon (n = 177 households), and semi-structured interviews with key informants (n = 24). We found that national food programs in Peru rarely provide foods that are desired and preferred among the Shawi, particularly familiar and locally-sourced protein sources such as bushmeat and fish. Food and social programming requirements do not integrate consideration of the remoteness of many vulnerable households, and are considered culturally or linguistically inaccessible to many families. In some cases, foods supplied by national programs are not consumed as they are perceived as unfamiliar. Key opportunities to improve food and social programing include: monitoring and revising eligibility requirements for remote and highly vulnerable households; increasing provision of locally-preferred protein food and familiar food types; avoiding use of written Spanish as a sole source of information to support programming; extending food provision outside of school months; developing contingency plans during education sector strikes; considering hiring of staff with working knowledge of local languages for community distributions; using visual or oral communication rather than written communication to increase accessibility of programs; increasing knowledge on the use and nutritional value of external food; and considering exemptions to school and health eligibility requirements during the rainy season and during sector strikes. Nationally-developed programming that does not consider Indigenous and cultural contexts risks inefficiency, limited improvement of health outcomes, and the potential to increase inequities in Indigenous health.     

Front-label health claims: when less is more

Growing global attention has been directed toward labeling the ingredients, processing methods, and health claims of food. Accompanying this attention is an interest in how consumers process or understand the information on such labels. This article examines how the length of a front-label claim influences the nutritional beliefs and evaluation of a product when used in combination with complete back-label information. The results indicate that the presence of a shorter health claim on the front of the package (in combination with a more complete claim on the back) leads a person to generate more attribute-specific thoughts about the product and fewer general evaluative thoughts compared to longer health claims. These shorter health claims also led to more favorable beliefs about the product and to a more positive image of the product. This article concludes with a discussion of the implications of the findings for policy makers, consumers and researchers.     

The demand for organic foods in the South of Italy: A discrete choice model

This paper analyses organic food consumer’s demand that can help advising on implementing organic food policies at European level or, for a particular European country. In particular, it investigates the main factors explaining organic food demand in the South of Italy. Following the Lancaster consumer’s demand theory we assume that consumer’s utility depends on product characteristics instead of the product itself. Thus, consumers will choose the product (organic versus conventional) that possesses the combination of attributes that maximises its utility. Consumer’s choice for organic foods is analysed within the random utility discrete choice model and a bivariate probit model has been specified. The data were collected through a questionnaire conducted in the Italian region of Campania (Naples) in 2003. Findings indicate that economic factors are still factors limiting the growth of organic demand in Europe. Moreover, the consumers’ perceived benefits of organic food (environmental and health) are factors promoting organic food demand. In addition, greater information on organic food products is crucial to expand its demand in the South of Italy because this information will increase the consumer’s organic knowledge. Then, higher organic knowledge will increase the probability to buy organic foods and, to a larger extent, the level of consumption among existing consumers.     

Does food processing mitigate consumers’ concerns about crops grown with recycled water?

This paper presents results from a field experiment designed to evaluate whether food processing alleviates consumers’ concerns about crops grown with recycled water. Recycled water has emerged as a potentially safe and cost-effective way to replace or supplement traditional irrigation water. However, adoption of recycled water by U.S. agricultural producers has been modest, in part, because of concerns that consumers will be reluctant to accept their products. Our results suggest that simple processing of foods such as drying or liquefying can relieve some of consumers’ concerns about use of recycled irrigation water. While consumers of processed foods are indifferent between irrigation with recycled and conventional water, they are less willing to pay for fresh foods irrigated with recycled water relative to conventional water. We also found that consumers would experience a welfare gain from a labeling policy communicating the use of recycled irrigation water on both processed and fresh foods. Our analysis further reveals that informational nudges that provide consumers with messages about benefits, risks, and both the benefits and risks of using recycled water have no statistically significant effect on consumers’ willingness to pay for fresh and processed foods irrigated with recycled water relative to a no-information control group.     

Do firms leverage the FDA nutrient label rounding rules to generate favorable nutrition fact panels or health claims?

The increasing incidence of nutrition related health concerns has made food labeling an important policy issue. Previous work suggests the importance of communicating nutrition information to consumers through product packaging. This paper investigates the role of labeling guidelines, which allow the rounding of calorie and nutrient levels on nutrition fact panels and affects front of package claims. We examine ready-to-eat cereal products as a bundle of nutrient attributes, and estimate the likelihood and magnitude of the rounding of specific nutrients and calories. We find systematic rounding, both up and down, of several nutrients, which affects allowable health claims and may influence consumer product choice and health outcomes.     

Adherence to WHO’s nutrition recommendations in the UK: Dietary patterns and policy implications from a national survey

Analysis of dietary patterns has largely focused on their association with diseases or risk factors, but limited research has been conducted on the heterogeneity of population dietary patterns and their adherence to international or national nutritional guidelines. As a result, the aim of this study is to identify latent dietary patterns of UK residents and to assess how well different segments comply with WHO dietary norms.To achieve this objective, the UK’s National Diet and Nutrition Surveys for 2011–12 dataset was analysed performing a latent class analysis on energy (kcals) derived from selected food groups. To assess adherence to different dietary patterns of the British population to nutritional guidelines, a traffic light system and a composite conformity index were developed to establish how well the identified segments comply with current dietary WHO norms regarding salt, free sugars, total fat, saturated fat, fruit and vegetables and dietary fibre.Results show four different segments which on the basis of heterogeneity of dietary patterns were named ‘high sugar/high fat consumers’, ‘prudent eaters’, ‘high fat consumers’ and ‘junk food eaters’. These segments show significant differences within and between groups in terms of dietary calories intakes and their adherence to WHO norms. Although ‘prudent eaters’ are closer to WHO dietary guidelines than other segments, none of the identified segments fully comply with dietary WHO norms. Policy implications of these findings are fully discussed in the conclusions arguing how current, future and potential dietary demand and supply measures affect consumers’ compliance with WHO norms.     

The impact of food advertisements on changing eating behaviors: An experimental study

This research examines how three types of food advertising (healthy food, unhealthy food, and anti-obesity) impact consumers’ purchases of lunch items. The analysis is based on an economic experiment conducted with 186 adult non-undergraduate student subjects, each of which were randomly placed into either the control group or one of four treatments: (1) healthy food advertising, (2) anti-obesity advertising, (3) unhealthy food advertising, and (4) mixed (all three food) advertising. The results indicate that healthy, anti-obesity, and mixed food advertising reduced intakes of total calories, fat, sodium, and carbohydrates. Similarly, anti-obesity, healthy, and mixed food advertising results in increasing the probability of selecting more healthy items and fewer unhealthy items from a menu. Healthy food advertising has a stronger impact than anti-obesity or mixed food advertising.
