    Attitudes - Food choice motives - Food Choices Questionnaire - Food4Me - Intention - Nutrigenomics - Personalised nutrition - Survey

    Objective: The present study explored associations between food choice motives, attitudes towards and intention to adopt personalised nutrition, to inform communication strategies based on consumer priorities and concerns. Design/Setting: A survey was administered online which included the Food Choice Questionnaire (FCQ) and items assessing attitudes towards and intention to adopt personalised nutrition. Subjects: Nationally representative samples were recruited in nine EU countries (n 9381). Results: Structural equation modelling indicated that the food choice motives ‘weight control’, ‘mood’, ‘health’ and ‘ethical concern’ had a positive association and ‘price’ had a negative association with attitude towards, and intention to adopt, personalised nutrition. ‘Health’ was positively associated and ‘familiarity’ negatively associated with attitude towards personalised nutrition. The effects of ‘weight control’, ‘ethical concern’, ‘mood’ and ‘price’ on intention to adopt personalised nutrition were partially mediated by attitude. The effects of ‘health’ and ‘familiarity’ were fully mediated by attitude. ‘Sensory appeal’ was negatively and directly associated with intention to adopt personalised nutrition. Conclusions: Personalised nutrition providers may benefit from taking into consideration the importance of underlying determinants of food choice in potential users, particularly weight control, mood and price, when promoting services and in tailoring communications that are motivationally relevant.

    Acceptance of Agri-Food Nanotechnology : Insights from the Evolution of Food Technology, Novel Foods and the Psychology of Novel Food Acceptance and Evidence from Present Research
    Gupta, Nidhi ; Frewer, Lynn ; Fischer, Arnout - \ 2017
    In: Nanotechnologies in Food / Chaudry, Qasim, Castle, Laurence, Watkins, Richard, Royal Society of Chemistry (Nanoscience & Nanotechnology Series 42) - ISBN 9781782621713 - p. 39 - 59.

    Food technology has evolved from being focused on the issues associated with food availability to include, more latterly, additional foci on food safety, sustainability and functionality. Despite the intuitive appeal of these beneficial factors in providing the basis for consumer acceptance of emerging technologies applied to food production, consumer acceptance of the benefits of agri-food nanotechnology will not be automatic. Understanding consumer psychology is essential if we are to understand and predict peoples' responses to (bio) nanotechnology in the agri-food sector. A review of the socio-psychological factors influencing the societal response to novel food technologies in the past may throw some light onto the possible trajectory of the societal response to agri-food applications of nanotechnology. This chapter draws insights from past research into the psychology of novel food acceptance, novel foods and the evolution of food technology, along with current evidence from present research on agri-food nanotechnology, to identify potential barriers and opportunities for the development and introduction of agri-food nanotechnology.

    The BROWSE model for predicting exposures of residents and bystanders to agricultural use of plant protection products: An overview

    New models have been developed, with the aim of improving the estimate of exposure of residents and bystanders to agricultural pesticides for regulatory purposes. These are part of a larger suite of models also covering operators and workers. The population that is modelled for residents and bystanders relates to people (both adults and children) who have no association with the application (i.e. not occupational exposure) but are adjacent to the treated area during and/or after the application process. The scenarios that the models aim to describe are based on consideration of both best practice and of real practice, as shown in surveys and from expert knowledge obtained in stakeholder consultations.

    The work has focused on three causes of exposure identified as having potential for improvement: boom sprayers, orchard sprayers and vapour emissions.

    An overview of the models is given, and a description of model input values and proposed defaults. The main causes of uncertainty in the models are also discussed. There are a number of benefits of the BROWSE model over current models of bystander and resident exposure, which includes the incorporation of mitigation measures for reducing exposure and the use of probabilistic modelling to avoid an over-conservative approach.

    It is expected that the levels of exposure that the BROWSE model predicts will, in some cases, be higher than those predicted by the current UK regulatory model. This is largely because the modelled scenarios have been updated to account for current practice and current scientific knowledge.

    Background: Personalised nutrition (PN) may promote public health. PN involves dietary advice based on individual characteristics of end users and can for example be based on lifestyle, blood and/or DNA profiling. Currently, PN is not refunded by most health insurance or health care plans. Improved public health is contingent on individual consumers being willing to pay for the service. Methods: A survey with a representative sample from the general population was conducted in eight European countries (N = 8233). Participants reported their willingness to pay (WTP) for PN based on lifestyle information, lifestyle and blood information, and lifestyle and DNA information. WTP was elicited by contingent valuation with the price of a standard, non-PN advice used as reference. Results: About 30% of participants reported being willing to pay more for PN than for non-PN advice. They were on average prepared to pay about 150% of the reference price of a standard, non-personalised advice, with some differences related to socio-demographic factors. Conclusion: There is a potential market for PN compared to non-PN advice, particularly among men on higher incomes. These findings raise questions to what extent personalized nutrition can be left to the market or should be incorporated into public health programs.

    Barriers to using consumer science information in food technology innovations: An exploratory study using Delphi methodology

    Consumer science - Food technology - Communication - Innovation - Delphi - Interdisciplinary
    Food technology innovation has the potential to deliver many benets to society, although some technologies have been problematic in terms of public acceptance. In promoting the commercial success of innovative technological processes and resultant products it will be important to incorporate
    information relating to consumer preferences and concerns during their development. The barriers to the utilisation of consumer information during technological development was explored using a two round Delphi study involving 75 experts with an interest in new food technology (food technologists and consumer scientists). There was overall agreement that consumer information should be used in technology implementation and product design, and that good communication between key actors at pivotal stages during the development of new food technologies and products was important.
    However disciplinary dierences were perceived to be a barrier to communication, as were diculties associated with producing consumer information usable by food technologists. A strategy to improve
    inter-disciplinary communication is proposed, involving the creation of multi-disciplinary teams working together throughout the development project's duration, including those with interdisciplinary experience. Deciencies in the specication of the information required from consumer scientists need
    to be overcome. Consumer science results need to be concrete and presented as salient to and usable by food technologists.

    Examining those risk and benefit perceptions utilised in the formation of attitudes and opinions about emerging technologies such as nanotechnology can be useful for both industry and policy makers involved in their development, implementation and regulation. A broad range of different socio-psychological and affective factors may influence consumer responses to different applications of nanotechnology, including ethical concerns. A useful approach to identifying relevant consumer concerns and innovation priorities is to develop predictive constructs which can be used to differentiate applications of nanotechnology in a way which is meaningful to consumers. This requires elicitation of attitudinal constructs from consumers, rather than measuring attitudes assumed to be important by the researcher. Psychological factors influencing societal responses to 15 applications of nanotechnology drawn from different application areas (e.g. medicine,agriculture and environment, food, military, sports, and cosmetics) were identified using repertory grid method in conjunction with generalised Procrustes analysis. The results suggested that people differentiate nanotechnology applications based on the extent to which they perceive them to be beneficial, useful,necessary and important. The benefits may be offset by perceived risks focusing on fear and ethical concerns. Compared to an earlier expert study on societal acceptance of nanotechnology, consumers emphasised ethical issues compared to experts but had less concern regarding potential physical contact with the product and time to market introduction. Consumers envisaged fewer issues with several applications compared to experts, in particular food applications.
    Food4Me study: Validity and reliability of Food Choice Questionnaire in 9 European countries

    motives - consumers
    This analysis has been conducted to explore the validity and reliability of the Food Choice Questionnaire (FCQ) across 9 European countries. Variation in the factor structure and the perceived importance of food choice motives have been compared cross-nationally. Volunteers (N = 9381) were recruited from an existing panel of a social research agency to take part in the Food4Me survey in Germany, Greece, Ireland, Poland, Portugal, Spain, the Netherlands, the UK and Norway. The survey was administered on-line. Configural, metric and scalar invariance fell within acceptable limits and were consistent across the 9 countries. All reliability parameters were above acceptable levels. Factor analysis confirmed that all items loaded onto the same 9 factors established by Steptoe and Pollard (1995). There was highly significant agreement in the relative importance of food choice factors between countries. Price was ranked as most important food choice factor in five countries (Spain, Greece, Ireland, Portugal and the Netherlands), sensory appeal was ranked first for three countries (Norway, Germany and the UK) while natural content was ranked as the most important factor in Poland. Familiarity and ethical concern were consistently ranked as least important in all countries. These data suggest that the FCQ is a suitable tool for exploring food choice motives across different European populations. Differences in relative importance of factors within countries may need to be taken into account in dietary health intervention and food product development.
    The perceived impact of the National Health Service on personalised nutrition service delivery among the UK public

    Personalised nutrition (PN) has the potential to reduce disease risk and optimise health and performance. Although previous research has shown good acceptance of the concept of PN in the UK, preferences regarding the delivery of a PN service (e.g. online v. face-to-face) are not fully understood. It is anticipated that the presence of a free at point of delivery healthcare system, the National Health Service (NHS), in the UK may have an impact on end-user preferences for deliverances. To determine this, supplementary analysis of qualitative data obtained from focus group discussions on PN service delivery, collected as part of the Food4Me project in the UK and Ireland, was undertaken. Irish data provided comparative analysis of a healthcare system that is not provided free of charge at the point of delivery to the entire population. Analyses were conducted using the ‘framework approach’ described by Rabiee (Focus-group interview and data analysis. Proc Nutr Soc 63, 655-660). There was a preference for services to be led by the government and delivered face-to-face, which was perceived to increase trust and transparency, and add value. Both countries associated paying for nutritional advice with increased commitment and motivation to follow guidelines. Contrary to Ireland, however, and despite the perceived benefit of paying, UK discussants still expected PN services to be delivered free of charge by the NHS. Consideration of this unique challenge of free healthcare that is embedded in the NHS culture will be crucial when introducing PN to the UK.
    Critical review of methodology and application of risk ranking for prioritisation of food and feed related issues, on the basis of the size of anticipated health impact

    This study aimed to critically review methodologies for ranking of risks related to feed/food safety and nutritional hazards, on the basis of their anticipated human health impact. An extensive systematic literature review was performed to identify and characterize the available methodologies for risk ranking in the fields of feed and food safety and nutritional hazards, as well as the socio-economic field. Risk ranking methods from the environmental field were studied as well to determine whether approaches used in this field could also be applied for ranking human health risks related to feed and food safety and nutritional hazards. The review used a predefined search protocol. It covered the bibliographic databases Scopus, CAB Abstracts, Web of Sciences, and PubMed over the period 1993-2013. All references obtained were stored into an Endnote database and evaluated for their relevance. All references deemed to be relevant were studied in–depth so as to characterize the risk ranking method described. Characteristics of each method were stored in an Excel database. The methods for risk ranking were then grouped into method categories, which were described in general. These groups included: risk assessment, comparative risk assessment, risk ratio method, scoring method, cost of illness, DALY/QALY, willingness to pay, multi criteria decision analysis, risk matrix, flow charts/decision trees and expert judgment methods. Based on the characteristics of the individual methods and the method categories, an overarching framework was developed for selection of the appropriate method(s) that could be used for risk ranking of feed and food related hazards, on the basis of human health impact. This framework has the format of a decision tool, with which – given the characteristics of the risk ranking question at hand - the most appropriate method(s) can be selected. Application of this overall framework to several case studies showed it can be a useful tool for risk managers/assessors to select the most suitable method for risk ranking of feed/food and diet related hazards, on the basis of expected human health impact.

    The notion of educating the public through generic healthy eating messages has pervaded dietary health promotion efforts over the years and continues to do so through various media, despite little evidence for any enduring impact upon eating behaviour. There is growing evidence, however, that tailored interventions such as those that could be delivered online can be effective in bringing about healthy dietary behaviour change. The present paper brings together evidence from qualitative and quantitative studies that have considered the public perspective of genomics, nutrigenomics and personalised nutrition, including those conducted as part of the EU-funded Food4Me project. Such studies have consistently indicated that although the public hold positive views about nutrigenomics and personalised nutrition, they have reservations about the service providers’ ability to ensure the secure handling of health data. Technological innovation has driven the concept of personalised nutrition forward and now a further technological leap is required to ensure the privacy of online service delivery systems and to protect data gathered in the process of designing personalised nutrition therapies.

    BACKGROUND: Double-blind placebo controlled food (DBPCFC) is the gold standard diagnostic test in food allergy because it minimizes diagnostic bias. OBJECTIVE: To investigate the potential effect of diagnosis on the socioeconomic costs of food allergy. METHODS: A prospective longitudinal cost analysis study was conducted in Spain and Poland within the EuroPrevall project. Food-allergic patients were enrolled into the study and in all cases diagnosis was confirmed through a standardized DBPCFC. Data were collected through a self-administered survey on all aspects of health and social care resource use, costs of living, and costs of leisure activities. Costs were measured before and 6 months after the DBPCFC and reported in international dollars with 2007 as the benchmark year. RESULTS: Forty-two patients were enrolled. Twenty-one patients had a negative DBPCFC and the suspected food was reintroduced into their diet. Comparing total direct costs before and after the DBPCFC, the reactive group spent a significantly higher amount (median increase of $ 813.1 over baseline), while the tolerant group's spending decreased by a median of $ 87.3 (P=0.31). The amount of money spent on food 6 months after diagnosis was also significantly higher in the reactive group (P=40). Finally, a larger, but not statistically significant, decrease in total indirect costs was observed in the tolerant group compared with the reactive group ($538.3 vs $ 32.3). CONCLUSION: DBPCFC has an impact on indirect and direct costs of living. The main contrubition to this increase was money to spent on food. Keywords: Food allergy. Double-Blind Placebo-Controlled Food Challenge. Diagnosis. Socioeconomic impact.

    The Nutrition Researcher Cohort (NRC) was launched at the 10th NuGOweek 2013 and represents a new generation research platform. Thereby, each individual provides and owns her/his selfquantification data on her/his health data using various gadgets and/or clinical analysis. The NRC approach is thus in a stepping-stone ‘development phase’ for a new way to merge observational research, personal health empowerment, (nutritional) intervention studies and preventive healthcare with the goal to become a globally accepted standard. Thereby, the NRC aims to renew the relationship between research and healthcare. Participants actively take part in research studies, by monitoring their health status themselves, instead of being passive data-and-blood-donating humans. In addition, participants will have a direct health benefit from participating in research by personalized health information and advice based on their personal data. We here present the first results of the initiation study, which included metabolomics and metabolite profiling of Dried Blood Spots (DBS) of finger prick blood, accomplished by five participating laboratories. Furthermore, all participants were asked to enter self-quantification data on food intake, anthropometrics, age, blood pressure, glucose response and several more. In total, about 300 metabolites were identified and relatively or absolutely quantified using LC-MS/MS and GC-MS. In addition, four trace elements were determined using total-reflection X-ray fluorescence analysis. Metabolite profiles will be connected to self-quantification data, anthropometrics and food intake. Thereof, first examples of visualization will be presented. The final aim is to provide personal advice on health, lifestyle and diet. As the NRC is a ‘crowd or citizen science’ initiative, any lab is invited to participate in optimizing and supplying DiY sampling (e.g. DBS, mucosal swaps) and analytics, metabolomics, data visualization and interpretation or other relevant methods.

    Abstract: Personalised nutrition is a relatively new field of research aiming to provide personalised dietary advice, which can be based on an individual’s genotype, phenotype, dietary and lifestyle data. According to this approach, dietary recommendations are tailored to meet personal nutritional needs. The goal of this analysis is to explore differences in perceived barriers to the uptake of personalised nutrition between consumers in different European countries. Data for this research were collected in February and March 2013, using on-line survey methodology. A total of 9381 participants from 9 European countries (Germany, Greece, Ireland, Poland, Portugal, Spain, the Netherlands, the UK, and Norway)participated. Perceived barriers for the adoption of personalised nutrition were measured using 18 items for which responses were on a five-point scale where respondents had to indicate their level of concern regarding various circumstances that could potentially prevent them from taking up personalised nutrition. Results showed significant differences between the 9 European countries in perceptions of barriers to the uptake of personalised nutrition. In some countries, like Greece, Spain and Germany, trust barrier was dominant while in other (e.g. Poland and Ireland) family and social barriers were deemed more important. This implies that policies targeted at promoting adoption of personalised nutrition need to be adapted for each country. Keywords: personalised nutrition, barriers, Europe

    The literature on public perceptions of, and attitudes towards, nanotechnology used in the agrifood sector is reviewed. Research into consumer perceptions and attitudes has focused on general applications of nanotechnology, rather than within the agrifood sector. Perceptions of risk and benefit associated with different applications of nanotechnology, including agrifood applications, shape consumer attitudes, and acceptance, together with ethical concerns related to environmental impact or animal welfare. Attitudes are currently moderately positive across all areas of application. The occurrence of a negative or positive incident in the agri-food sector may crystallise consumer views regarding acceptance or rejection of nanotechnology products.

    Objective To develop a model of the psychological factors which predict people’s intention to adopt personalised nutrition. Potential determinants of adoption included perceived risk and benefit, perceived self-efficacy, internal locus of control and health commitment. Methods A questionnaire, developed from exploratory study data and the existing theoretical literature, and including validated psychological scales was administered to N = 9381 participants from 9 European countries (Germany, Greece, Ireland, Poland, Portugal, Spain, the Netherlands, the UK, and Norway). Results Structural equation modelling indicated that the greater participants’ perceived benefits to be associated with personalised nutrition, the more positive their attitudes were towards personalised nutrition, and the greater their intention to adopt it. Higher levels of nutrition self-efficacy were related to more positive attitudes towards, and a greater expressed intention to adopt, personalised nutrition. Other constructs positively impacting attitudes towards personalised nutrition included more positive perceptions of the efficacy of regulatory control to protect consumers (e.g. in relation to personal data protection), higher self-reported internal health locus of control, and health commitment. Although higher perceived risk had a negative relationship with attitude and an inverse relationship with perceived benefit, its effects on attitude and intention to adopt personalised nutrition was less influential than perceived benefit. The model was stable across the different European countries, suggesting that psychological factors determining adoption of personalised nutrition have generic applicability across different European countries. Conclusion The results suggest that transparent provision of information about potential benefits, and protection of consumers’ personal data is important for adoption, delivery of public health benefits, and commercialisation of personalised nutrition.

    Purpose – Food products developed using genetically modified (GM) animals may soon be introduced in Europe and beyond. Their successful commercialisation depends on consumer acceptance, and so it is timely to review the existing literature in this respect. The paper aims to discuss these issues. Design/methodology/approach – A systematic review identified 42 English language peer reviewed papers assessing public opinion of GM animals associated with food production. Thematic analysis was applied to the results to identify and explain consumer attitudes. Findings – Publication peaked in 2004, and declined thereafter. European consumers were less accepting of GM animal technology than the US and Asian consumers, although the latter reported more ethical concern. Risk and benefit perceptions, ethical concerns (e.g. related to animal welfare) may explain negative consumer attitudes towards animals in food production. Research limitations/implications – There is a lack of data on consumer attitudes to GM animals applied to food production, in particular in relation to consumers in emerging economies and developing countries. This is problematic as applications of GM animal products are about to enter the market. Practical implications – There is a need to track changes in public opinion as GM food production animals are further developed. The introduction and commercialisation of applications with specific characteristics may further shape consumer attitudes. Social implications – Methods need to be developed to involve consumers and other stakeholders in shaping future applications of agri-food applications of GM animals. Originality/value – The review collates existing quantitative and qualitative knowledge regarding the drivers of consumer attitudes towards GM animals used in food production using systematic review methodology.

This paper attempts to answer these questions through a structured review of the academic literature, focusing on the identification of ‘methodologies’ of expert involvement, and on analying the subsequent policy impact of those exercises. Coding was applied to 103 articles, revealing that only a small range of methods has been utilised, that method choice is infrequently justified, and with little evidence of evaluation (either of the expert involvement process or of policy impact). We argue that robust evaluative processes are necessary to refine the efficacy of involvement processes (and the accuracy with which involvement methods are aligned to specific types of policy questions) and to document policy translation of outcomes. We therefore propose a framework to identify appropriate consultation methods for specific policy questions, and suggest some criteria for reporting expert involvement processes in the future. Keywords: expert involvement; policy development; policy translation; stakeholder involvement; systematic review.
